What problem does internal link optimisation solve for Irish websites?
You have published forty blog posts. Maybe fifty. You have spent real money on content, maybe even hired a copywriter who actually understood your industry. And yet half those pages get zero traffic. Some of them have never even appeared in Google's index. They just sit there, invisible, gathering digital dust while your competitors rank for the exact terms you targeted.
Sound familiar? You are not alone.
This is one of the most common problems I see when auditing Irish websites, from solicitors in Dublin to e-commerce shops shipping across Munster to accountancy firms in Galway. The content exists. It might even be good. But it is poorly connected. There is no clear path from one page to the next, no structure telling Google which pages matter most, and no logical journey for a visitor who lands on your site and wants to explore.
The fix is not more content. Not yet, anyway. The fix is internal linking.
Internal linking is one of those SEO fundamentals that gets talked about in every "top 10 SEO tips" listicle but rarely gets the thorough treatment it deserves. Most advice boils down to "add more internal links." That is like telling someone to "eat healthier" without explaining what a balanced meal looks like.
In this guide, I am going to walk you through the full picture. What internal links actually are. Why they matter so much for both rankings and user experience. How to build a strategy that works, specifically for the kinds of websites we see here in Ireland, whether that is a five-page brochure site for a plumber in Cork or a 2,000-product online store. We will cover best practices, common mistakes, tools you can use today, and a checklist you can work through this week.
A few things to set expectations upfront. Internal linking is not an overnight rankings hack. It will not take a page from position 80 to position 1 by next Tuesday. What it will do, consistently and reliably, is improve how Google discovers your content, help your most important pages accumulate more authority, and make your website genuinely easier for people to use. Over time, that compounds. And in a competitive Irish market where most SMEs are not doing this well, it can be a real advantage.
What are internal links (and how are they different from external links and backlinks)?
Let us start with the basics, because the terminology gets muddled surprisingly often.
An internal link is a link from one page on your website to another page on the same website. If you are on your homepage at example.ie and you click a link that takes you to example.ie/services/seo, that is an internal link. Both pages live on the same domain. Simple enough.
An external link (sometimes called an outbound link) is a link from your website to a different website entirely. If your blog post links to a Wikipedia article or a government resource on revenue.ie, that is an external link. You are sending the visitor away from your domain.
Now here is where people get confused. Backlinks. A backlink is a link from someone else's website pointing to yours. If The Irish Times publishes an article and links to your site, that is a backlink for you. Backlinks are one of the strongest ranking signals in SEO, and they are notoriously hard to earn.
Are internal links "backlinks"? No. They are not the same thing. You control internal links entirely. You cannot control who links to you from the outside. Both matter, but they serve different purposes. Backlinks build your domain's overall authority. Internal links distribute that authority across your pages and tell Google how your content is organised.
What is a link and what is anchor text?
A link, in its simplest form, is a clickable element on a web page that takes you somewhere else. The visible, clickable text that the user actually sees and clicks is called anchor text.
Anchor text matters because it gives context. It tells both the reader and Google what the linked page is about before anyone clicks on it. Compare these two links:
- "Learn more about our SEO audit process for Irish businesses"
- "To learn more, click here"
The first one is descriptive. Google reads that anchor text and understands the destination page has something to do with SEO audits for Irish businesses. The second tells Google nothing useful. "Click here" could lead anywhere.
This distinction matters more than most people realise. We will come back to anchor text best practices later, because getting it right is one of the easiest wins in internal link optimisation.
What are the main types of internal links I should use?
Not all internal links are created equal. There are three broad categories, and a solid website uses all of them.
Structural and navigational links. These are the links baked into your site's template: your main menu, your footer links, sidebar navigation, breadcrumbs, category pages. They appear on every page (or most pages) and form the skeleton of your site. When someone lands on your homepage, the menu is what guides them to "Services," "About," "Blog," "Contact." Breadcrumbs show the path from homepage to current page, like Home > Services > SEO Audit. These links are fundamental to how Google understands your site hierarchy.
Contextual links within content. These are the editorial links you place inside your blog posts, service page descriptions, case studies, and other written content. They sit naturally within paragraphs. For example, in a blog post about technical SEO, you might write: "One of the first things we check is whether your XML sitemap is properly configured." That link to your sitemap guide is a contextual internal link. These carry significant weight because they are placed deliberately, in relevant context, surrounded by topically related text.
Related content modules. "Related articles," "You may also like," "Further reading" sections at the bottom of blog posts or product pages. These are semi-automated in most CMS platforms. They help keep visitors on your site and expose them to content they might have missed. Not as powerful as a well-placed contextual link, but still valuable for discovery and engagement.
Why are internal links important for SEO (and user experience)?
I could give you the textbook answer here. But let me put it in practical terms instead.
They help Google actually find your pages. Google discovers new content primarily by following links. If you publish a new blog post but it is not linked from anywhere else on your site, Google's crawler may never find it. Or it may take weeks. Internal links create crawl paths, the routes Googlebot follows to discover and revisit your content. For smaller Irish sites with limited external backlinks, internal links are often the primary way Google navigates your site.
They establish your site's hierarchy and topical structure. Which pages on your site are most important? Google figures this out partly by looking at your internal link structure. A page that is linked from your homepage, your main navigation, and fifteen blog posts is clearly more important than one buried three clicks deep with a single link from an old article. Internal links are how you signal priority.
They distribute link equity internally. When an external site links to your homepage (which is where most backlinks tend to point), that authority does not just sit on the homepage. It flows through internal links to other pages on your site. Smart internal linking means you can channel some of that authority to your most important service pages, location pages, or conversion-focused content. Think of it as plumbing. The water (authority) comes in through the main pipe (backlinks to your homepage), and internal links are the pipes that distribute it throughout the house.
They strengthen topical authority through clusters. If you have a pillar page about "accountancy services in Dublin" and ten supporting articles about specific topics (tax returns, VAT registration, payroll, company formation), linking them all together tells Google this site has comprehensive coverage of accountancy. That topical depth matters. Google increasingly rewards sites that demonstrate genuine expertise in a subject area, and internal linking is how you prove the connections between your content.
They provide contextual clarity. The anchor text and surrounding content around an internal link reinforce what the target page is about. If five different articles link to your "SEO audit" page using anchors like "comprehensive site audit," "technical SEO review," and "full website health check," Google builds a richer understanding of what that page covers.
They improve navigation and engagement. This is the bit that directly affects your visitors, not just your rankings. Good internal links keep people on your site longer. They reduce pogo-sticking (when someone clicks back to Google immediately because they did not find what they wanted). They create natural pathways: someone reading about content marketing might want to know about keyword research next, and a well-placed internal link takes them there without effort.
They increase visibility of key pages. Your services page. Your contact page. Your booking form. Your location-specific landing pages. These are the pages that actually generate leads and revenue. Internal linking is how you make sure visitors (and Google) can always find them easily, no matter where on your site they enter.
How do I build a cohesive internal linking strategy (site architecture + topic clusters)?
Here is where most people go wrong. They start adding links randomly, sprinkling them into blog posts without any plan. A link here, a link there. It is better than nothing, but it is not strategy.
A proper internal linking strategy starts with structure.
Determine your website structure before adding lots of links
Before you start linking things together, you need to know what you are linking and why. Think of your website as a building. You would not start running electrical wiring before you have the walls up.
Most business websites follow a similar hierarchy:
- Homepage at the top, linking to your main sections
- Category or service pages one level down (e.g., "SEO Services," "Web Design," "Content Marketing")
- Detail pages beneath those (e.g., "Technical SEO Audit," "Local SEO for Dublin," "E-commerce SEO")
- Supporting content like blog posts, case studies, FAQs, and guides
This is sometimes called a "flat" or "shallow" architecture, meaning any page on your site should be reachable within three or four clicks from the homepage. Deep, maze-like structures where pages are buried six clicks deep are bad for both users and crawlers.
If you are running a small service-based business in Ireland, say a physiotherapy clinic in Limerick, your structure might be straightforward: Homepage > Services (Back Pain, Sports Injury, Post-Surgery Rehab) > Blog. But even that simple structure benefits enormously from deliberate internal linking between the blog and those service pages.
How do I identify my most important content to prioritise?
Not every page deserves equal linking attention. You need to know which pages are your priorities.
Money pages. These are the pages that directly generate business. Your services page, your contact page, your booking form, your product pages if you are in e-commerce. These should receive the most internal links from across your site.
High-intent informational pages. Content that catches people when they are close to making a decision. A page about "how much does an SEO audit cost in Ireland" is closer to a conversion than "what is SEO." The former should get more internal link attention.
Evergreen resources. Comprehensive guides, tools, calculators, or reference pages that remain relevant over time. These tend to accumulate backlinks naturally and serve as strong hubs in your internal link structure.
Make a list. Write down your top 10 to 15 pages. These are the ones you are going to focus on linking to from every relevant piece of content on your site.
How do I create topic clusters and add contextual links?
Topic clusters are the backbone of modern content strategy, and internal linking is what holds them together.
The concept is straightforward. Pick a broad topic that is central to your business. Create a comprehensive pillar page that covers that topic broadly. Then create supporting articles that go deep on specific subtopics. Link them all together.
Here is a concrete example. Say you run an SEO agency (like we do at BeFound). Your pillar page might be "SEO Services Ireland," a comprehensive page covering everything you offer. Your supporting articles might include:
- What is a technical SEO audit?
- How to do keyword research for Irish businesses
- Local SEO tips for Dublin service businesses
- How to optimise your Google Business Profile
- Why site speed matters for SEO
Each supporting article links back to the pillar page. The pillar page links out to the most relevant supporting articles. And where it makes sense, supporting articles link to each other. The result is a tightly connected web of content that signals to Google: "This site knows SEO inside and out."
The linking should be two-way, but it does not need to be symmetrical. Your pillar page should link to perhaps five or six of the best supporting articles. Every supporting article should link back to the pillar. And when a supporting article naturally references a topic covered in another supporting article, link to it.
How do I handle location intent for Ireland?
This comes up constantly with Irish businesses, especially those serving multiple areas. You have a national service page, and then you want to rank in Dublin, Cork, Galway, Limerick, and Waterford individually.
The wrong approach: create five nearly identical pages with just the city name swapped out. Google sees through this. Thin, duplicate location pages can actually hurt you.
The right approach: make each location page genuinely unique and useful. Your "SEO Services Dublin" page should mention specific things about operating in Dublin, reference Dublin-based clients or case studies if you have them, and address challenges specific to that market. Your Cork page should do the same for Cork.
Internal linking between location pages should be natural. Your national "SEO Services Ireland" page should link to each location page. Each location page should link back to the national page. But you do not need every location page linking to every other location page unless there is a genuine reason. A simple "We also serve Cork, Galway, and Limerick" line at the bottom is perfectly fine and much better than a forced grid of cross-links.
What are internal link best practices for SEO?
Now for the practical guidance. These are the rules I follow when optimising internal links for our clients, and for our own site at BeFound.
Use descriptive, keyword-rich anchor text. We covered this earlier, but it bears repeating. "Our technical SEO audit service" is better than "click here to learn about our services." You are telling Google and the reader exactly what to expect on the other end of that link. But do not go overboard. Stuffing exact-match keywords into every anchor looks unnatural and can trigger penalties.
Link deep. Everyone remembers to link to their homepage and contact page. Few people remember to link to their detailed service pages, their older blog posts, or their case studies. These deeper pages are precisely the ones that need internal links most, because they are least likely to get them naturally.
Prioritise links from your strongest pages. If your homepage has the most authority (which it usually does), links from your homepage carry more weight. If a particular blog post has attracted lots of backlinks, use it to link to your most important pages. Authority flows through links, so link from where you have it to where you need it.
Keep links contextually relevant. Do not shoe-horn a link to your "wedding photography packages" into a blog post about corporate headshots just because you want to boost the wedding page. The link should make sense to the reader. If they would naturally want to explore that topic next, link it. If you have to stretch to justify the connection, skip it.
Fix broken internal links promptly. A link to a page that no longer exists (returning a 404 error) is worse than no link at all. It wastes crawl budget, breaks the user experience, and leaks the authority that link was supposed to pass. We will talk about how to find these shortly.
Do not overload pages with internal links. There is a point of diminishing returns. If a 1,000-word blog post contains 30 internal links, each one carries very little individual weight, and the page looks spammy to readers. More importantly, it becomes genuinely hard to read. Quality over quantity, always.
Use follow links for your internal pages. This sounds obvious, but I have seen it happen: sites that accidentally add rel="nofollow" to their own internal links, usually through a poorly configured plugin or a theme that adds nofollow to all links by default. Nofollow tells Google "don't pass authority through this link." You almost never want that for your own internal links.
How many internal links should a page have?
There is no magic number. Google's John Mueller has said repeatedly that there is no specific limit. The old "100 links per page" guideline from years ago is outdated and was never a hard rule.
Here is a better way to think about it. For a typical blog post of 1,500 to 2,500 words, I would expect to see somewhere between 3 and 10 contextual internal links. That does not count navigational links in your header, footer, and sidebar, which are site-wide and expected.
For a large e-commerce category page, you might have hundreds of internal links (to products, subcategories, filters). That is fine. It is the nature of the page.
The real test: would a reader benefit from this link? Would they naturally want to explore the linked page next? If yes, include it. If you are adding the link purely for SEO purposes and it interrupts the reading experience, question whether it belongs.
What anchor text should I use for internal links?
This is worth going into some detail on, because anchor text strategy for internal links is different from external link building.
Exact match anchor text uses the target keyword precisely. If your page targets "SEO audit Ireland," your anchor text is "SEO audit Ireland." This is fine to use occasionally for internal links. Unlike external backlinks, where heavy exact-match anchoring can trigger Google Penguin penalties, internal links have more flexibility. But "occasionally" is the key word. If every single internal link pointing to that page uses the identical phrase, it starts looking manufactured.
Partial match anchor text is usually the best approach. It includes the target keyword or close variations naturally within a phrase. "Our comprehensive SEO audit for Irish businesses" or "we start every engagement with a full technical site audit." The keyword is there, but it reads naturally within the sentence.
Branded anchors like "BeFound's approach" or generic anchors like "read more" and "learn more" are fine as supplementary anchors but terrible as your primary ones. They waste an opportunity to provide context. If most of your internal links use "click here" or "read more," you are leaving value on the table.
A healthy internal link profile for any given page has a mix: mostly partial match, some exact match, the occasional branded or descriptive anchor. Variety is natural. Monotony is suspicious.
How do I find and fix internal linking problems on my website?
Knowing what to do is only half the battle. You also need to know what is currently broken. Here is how to audit your internal links.
How to audit existing internal links
Screaming Frog SEO Spider. This is my go-to tool for technical audits, and the free version crawls up to 500 URLs, which covers most small to medium Irish business websites. Run a crawl and you will get a complete map of every internal link on your site: which pages link where, what anchor text they use, and which pages have the fewest inbound internal links. For most of the sites we work with in Ireland, 500 URLs is more than enough. If you need more, the paid licence is well worth it.
Ahrefs Site Audit. If you have an Ahrefs subscription, their Site Audit tool is excellent for internal link analysis. It identifies orphan pages, broken links, redirect chains, and pages with low internal link counts. The visualisation tools are particularly useful for understanding your site structure at a glance.
Google Search Console. Free and already set up for most sites. The Coverage report shows you which pages Google has indexed and which it has not (and why). The Links report, found under "Links" in the left sidebar, shows you which pages on your site receive the most internal links. If your most important service page is not near the top of that list, you have work to do.
Common problems to look for
Orphan pages. These are pages with zero internal links pointing to them. Google can only find them if they are in your sitemap or have external backlinks. For a small Irish business site, orphan pages are shockingly common. Someone publishes a blog post, forgets to link to it from anywhere, and it sits there undiscovered. Check for these first. They are the quickest win.
Over-linked pages. Your homepage probably has links to every page in your navigation, footer, and maybe a featured content section. That is normal. But if it also has 200 links in the body content, each individual link carries very little weight. More is not always better.
Broken links. Internal links pointing to pages that return 404 errors. This happens when you delete or rename a page without setting up redirects. Every broken internal link is a dead end for both users and crawlers.
Redirect chains. Page A links to Page B, but Page B redirects to Page C, which redirects to Page D. Every hop in the chain wastes crawl budget and dilutes the authority being passed. Ideally, every internal link should point directly to the final destination URL, not to a page that redirects.
Nofollow internal links. As mentioned earlier, some plugins or themes add nofollow attributes to internal links. Check for this. Your internal links should almost always be standard follow links.
Generic anchor text everywhere. If a Screaming Frog crawl shows that your most common internal link anchors are "click here," "read more," "learn more," and "this page," you are missing opportunities. Each of those should be replaced with descriptive, contextual anchor text.
How does internal linking work differently for different types of Irish websites?
Not every site is the same. The principles are consistent, but the application varies depending on what kind of website you are running.
Internal linking for service-based businesses (solicitors, accountants, tradespeople)
This is the most common type of website we work with in Ireland. A solicitor in Dublin with a dozen service pages, a handful of blog posts, and an about page.
The strategy here is straightforward. Your service pages are hubs. Every relevant blog post should link back to the appropriate service page. Writing about the process of buying a house? Link to your conveyancing service page. Writing about employment law updates? Link to your employment law service page.
And it works the other way too. Your service pages should link out to relevant blog posts, case studies, or client testimonials that support the claims you are making. "We have helped dozens of Dublin businesses with employment disputes" is stronger when it links to an actual case study.
For location pages, link them to each other sensibly. If you are a plumber covering Dublin, Kildare, and Wicklow, your Dublin page might mention that you also cover neighbouring counties, with links. But do not force a matrix of cross-links between every location page. It should feel natural.
Internal linking for e-commerce sites in Ireland
E-commerce internal linking is a different beast. You are dealing with potentially hundreds or thousands of product pages, category pages, filter options, and sorting parameters.
Category pages to product pages is the foundational link structure. Every product should be reachable from its parent category within one click. Products should also link to related products ("customers also bought," "you might also like") and to relevant buying guides or FAQ content.
Blog content is your secret weapon here. A well-written buying guide about "choosing the right running shoes for Irish weather" that links to your actual running shoe category page is incredibly powerful. It captures informational search intent and funnels readers toward transactional pages.
One major pitfall for e-commerce sites: faceted navigation. Filters for size, colour, price range, and brand can generate thousands of URL variations, most of which are thin, duplicate, or near-duplicate pages. If Google tries to crawl all of them, it wastes your crawl budget on low-value pages. Use canonical tags, robots directives, or parameter handling in Search Console to manage this. That is a whole topic in itself, but it is worth mentioning because poor faceted navigation is one of the most common technical SEO issues we see on Irish e-commerce sites.
Internal linking for blogs and content sites
If your site is primarily content-driven, think about news sites, niche blogs, or media publications, your internal linking strategy revolves around topic clusters.
Pick your pillar topics. Create comprehensive pillar posts for each one. Then create supporting articles that go deep on specific angles. Link them together. We covered this structure earlier, but the key point for content sites is ongoing maintenance.
When you publish a new article, add links to it from relevant older articles. This is the step most people skip. They write the new post, link from it to older content, and publish. But they forget to go back to those older articles and add a link to the new one. Those older articles have had time to accumulate authority and backlinks. A link from them to your new content is valuable. Do not leave it on the table.
Set a recurring task, monthly or quarterly, to review your most popular posts and update their internal links. New content gets published. Old links break. Topics evolve. Internal linking is not a "set it and forget it" job.
What tools help with internal link optimisation?
You do not need expensive software to do this well, but the right tools make it faster and more thorough.
Screaming Frog SEO Spider. The best technical crawling tool available. The free version handles up to 500 URLs and gives you everything you need for a small to medium website: internal link mapping, anchor text analysis, broken link detection, redirect chain identification. If your site is larger than 500 pages, the annual licence (around £199 per year) is money well spent. This is the first tool I open for any internal link audit.
Ahrefs Site Audit. Part of the broader Ahrefs toolset. It crawls your site and presents internal link data in a more visual, digestible format than Screaming Frog. Particularly useful for finding orphan pages and understanding link distribution across your site. It requires a paid Ahrefs subscription, but if you are already using Ahrefs for backlink analysis and keyword research, the Site Audit feature is included.
Google Search Console. Free. The internal links report (under Links > Internal Links) shows you which pages on your site receive the most internal links. Compare this against your list of priority pages. If your most important service page has fewer internal links than a random blog post from 2019, that is a problem you can fix today.
Link Whisper. A WordPress plugin that suggests internal link opportunities as you write. It scans your existing content and recommends relevant pages to link to. It is not perfect, some suggestions are a stretch, but it surfaces opportunities you might miss manually. Especially useful if you have a large content library and cannot remember every post you have published.
Yoast SEO and RankMath. Both of these popular WordPress SEO plugins offer internal link suggestions as you write. They are less sophisticated than Link Whisper, but since most Irish websites already have one of these installed, you might as well use the feature. Yoast's internal linking suggestions appear in the sidebar as you edit a post, showing related content you could link to.
Internal link optimisation checklist for Irish websites
Here is a practical checklist you can work through. Do not try to do everything at once. Pick the first two or three items, complete them, then move on.
- Audit your current internal links. Run a Screaming Frog crawl or Ahrefs Site Audit. Identify orphan pages, broken links, and redirect chains. Export the data so you have a baseline.
- Identify your 10 to 15 most important pages. Write them down. These are your money pages, your best-performing content, and your core service/location pages. Every one of these should have strong internal link support.
- Create or update a hub-and-spoke topic cluster structure. Map out your pillar topics and supporting articles. Draw the connections. Then build the links.
- Review anchor text quality across the site. Replace generic anchors ("click here," "read more") with descriptive, keyword-informed alternatives. Vary your anchor text so it looks natural.
- Fix broken internal links. Every 404 link you find in your crawl data should be either updated to point to the correct URL or removed entirely. Set up 301 redirects for any pages you have deleted or moved.
- Ensure location pages link coherently. If you serve multiple Irish cities or counties, check that your location pages link to each other and to relevant service pages in a way that makes sense for users.
- Add contextual links in blog posts. Go through your most recent and most popular blog posts. For each one, add two or three internal links to relevant service pages, pillar content, or related articles. Then do the same in reverse: update older posts to link to newer content.
- Re-crawl after changes. Once you have made your updates, run another crawl to confirm the improvements. Check that orphan pages are now linked, broken links are fixed, and your priority pages have more internal links than before.
This is not a one-time exercise. Internal link optimisation should be part of your ongoing content process. Every time you publish a new page, ask: "What should link to this, and what should this link to?"
Frequently asked questions about internal link optimisation
Do internal links help SEO?
Yes. Internal links help Google discover, crawl, and index your pages. They distribute authority across your site, signal which pages are most important, and strengthen topical relevance through anchor text and content clustering. They also improve user experience by making your site easier to navigate, which can indirectly support rankings through better engagement signals. Internal links are one of the few ranking factors you have complete control over.
How many internal links should I have on a page?
There is no official limit. The right number depends on the page type and content length. A typical blog post might have 3 to 10 contextual internal links. A category page on an e-commerce site might have dozens or hundreds (linking to products and subcategories). The guiding principle: every link should serve the reader. If it helps them find useful, related content, include it. If it is there only for SEO manipulation, leave it out.
What is the best anchor text for internal links?
Descriptive, partial-match anchor text is generally the best approach. Instead of "click here," use phrases that naturally include relevant keywords, like "our guide to technical SEO" or "find out about our Dublin-based SEO services." Use a mix of exact match, partial match, and natural variations. Avoid using the exact same anchor text for every link pointing to a given page.
Can too many internal links hurt SEO?
In theory, an excessive number of links on a single page dilutes the authority passed by each individual link. In practice, this is mainly a concern for user experience. If a page is so overloaded with links that it becomes difficult to read or navigate, that is a problem. Google is unlikely to penalise you for having too many internal links, but users might leave. Focus on quality and relevance rather than quantity.
What is an orphan page in SEO?
An orphan page is a page on your website that has no internal links pointing to it from any other page on the site. Because Google primarily discovers content by following links, orphan pages are often not indexed at all, or they are indexed very slowly. Common causes include publishing a blog post without linking to it from existing content, removing a page from your navigation without redirecting it, or migrating a site and losing internal link connections. The fix is simple: add relevant internal links from existing pages.
