Optimising Internal Links for SEO

You’ve published forty blog posts. Maybe fifty. You’ve 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’re not alone.

This is one of the most common problems I see when auditing Irish websites:

  • Solicitors in Dublin with excellent practice area pages that Google never finds
  • E-commerce shops shipping across Munster with product pages buried in their site structure
  • Accountancy firms in Galway with valuable tax guides that get zero organic traffic

The content exists. It might even be good. But it’s poorly connected. There’s no clear path from one page to the next, no structure telling search engines which pages matter most, and no logical journey for a visitor who lands on your site and wants to explore.

The fix isn’t more content. Not yet, anyway. The fix is internal linking.

Why internal linking matters more than you think

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’s like telling someone to “eat healthier” without explaining what a balanced meal looks like.

In this guide, I’m going to walk you through the full picture:

  • What internal links actually are (and how they differ from external links and backlinks)
  • Why they matter so much for both rankings and user experience
  • How to build a strategy that works, specifically for Irish websites
  • Best practices that you can implement today
  • Common mistakes I see on Irish business sites
  • Tools you can use to find and fix internal linking issues
  • A practical checklist you can work through this week

A few things to set expectations upfront. Internal linking isn’t an overnight rankings hack. It won’t 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
  • Make your website genuinely easier for people to use

Over time, that compounds. And in a competitive Irish market where most SMEs aren’t doing this well, it can be a real advantage.

Let’s start with the basics, because the terminology gets muddled surprisingly often.

Link Type

Definition

Example

Who Controls It?

Internal Link

A link from one page on your site to another page on the same site

Homepage → Services page

You (completely)

External Link

A link from your website to a different website

Your blog → Wikipedia

You (completely)

Backlink

A link from another website pointing to yours

Irish Times → Your site

Others (not you)

Here’s where people get confused. Are internal links “backlinks”? No. They’re not the same thing. You control internal links entirely. You can’t 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

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 search engines what the linked page is about before anyone clicks on it. Compare these two links:

Anchor Text Example

SEO Value

User Value

“Learn more about our SEO audit process for Irish businesses”

High – descriptive and keyword-rich

High – clear expectation

“Click here”

Low – no context

Low – unclear destination

This distinction matters more than most people realise. We’ll come back to anchor text best practices later, because getting it right is one of the easiest wins in internal link optimisation.

Not all internal links are created equal. There are three broad categories, and a solid website uses all of them:

These are the links baked into your site’s template:

  • Main menu navigation
  • 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.” These links are fundamental to how search engines understand your site hierarchy.

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’re placed deliberately, in relevant context, surrounded by topically related text.

These include:

  • “Related articles” sections
  • “You may also like” recommendations
  • “Further reading” suggestions

They’re semi-automated in most CMS platforms. Not as powerful as a well-placed contextual link, but still valuable for discovery and engagement.

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 page but it’s 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 search engines navigate 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 linked from your homepage, main navigation, and fifteen blog posts = clearly important
  • A page buried three clicks deep with a single link from an old article = not so important

Internal links are how you signal priority.

When an external site links to your homepage (which is where most backlinks tend to point), that authority doesn’t just sit on the homepage. It flows through internal links to other pages on your site.

Think of it as plumbing:

  • The water (authority) comes in through the main pipe (backlinks to your homepage)
  • Internal links are the pipes that distribute it throughout the house

Smart internal linking means you can channel some of that authority to your most important service pages, location pages, or conversion-focused content.

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”
  • “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
  • Reduce pogo-sticking (when someone clicks back to Google immediately)
  • Create natural pathways between related content

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 money pages – services, contact, booking forms, location-specific landing pages – these 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 an effective internal linking strategy?

Here’s 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’s better than nothing, but it’s not strategy.

A proper internal linking strategy starts with structure.

Before you start linking things together, you need to know what you’re linking and why. Think of your website as a building. You wouldn’t start running electrical wiring before you have the walls up.

Most business websites follow a similar hierarchy:

  1. Homepage at the top, linking to your main sections
  2. Category or service pages one level down (e.g., “SEO Services,” “Web Design,” “Content Marketing”)
  3. Detail pages beneath those (e.g., “Technical SEO Audit,” “Local SEO for Dublin,” “E-commerce SEO”)
  4. 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.

Topic clusters linking pillar pages to supporting content

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:

  1. Money pages. These are the pages that directly generate business. Your services page, your contact page, your booking form, your product pages if you’re in e-commerce. These should receive the most internal links from across your site.
  2. High-intent informational pages. Content that catches people when they’re 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.
  3. 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’re going to focus on linking to from every relevant piece of content on your site.

Topic clusters are the backbone of modern content strategy, and internal linking is what holds them together.

The concept is straightforward:

  1. Pick a broad topic that’s central to your business
  2. Create a comprehensive pillar page that covers that topic broadly
  3. Create supporting articles that go deep on specific subtopics
  4. Link them all together

Here’s a concrete example for an SEO agency like BeFound:

The linking should be two-way, but it doesn’t need to be symmetrical:

  1. Your pillar page should link to perhaps five or six of the best supporting articles
  2. Every supporting article should link back to the pillar
  3. 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:

  1. Your “SEO Services Dublin” page should mention specific things about operating in Dublin
  2. Reference Dublin-based clients or case studies if you have them
  3. Address challenges specific to that market
  4. Your Cork page should do the same for Cork

Internal linking between location pages should be natural:

  1. Your national “SEO Services Ireland” page should link to each location page
  2. Each location page should link back to the national page
  3. You don’t need every location page linking to every other location page unless there’s a genuine reason
  4. A simple “We also serve Cork, Galway, and Limerick” line at the bottom is perfectly fine

What are the best practices for internal linking?

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.

1. 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’re telling Google and the reader exactly what to expect on the other end of that link.

But don’t go overboard. Stuffing exact-match keywords into every anchor looks unnatural and can trigger penalties.

Everyone remembers to link to their homepage and contact page. Few people remember to link to:

  1. Detailed service pages
  2. Older blog posts
  3. Case studies
  4. FAQ pages

These deeper pages are precisely the ones that need internal links most, because they’re least likely to get them naturally.

Authority flows through links. 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.

Don’t 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.

Ask yourself: Would they naturally want to explore that topic next? If yes, link it. If you have to stretch to justify the connection, skip it.

A link to a page that no longer exists (returning a 404 error) is worse than no link at all. It:

  1. Wastes crawl budget
  2. Breaks the user experience
  3. Leaks the authority that link was supposed to pass

We’ll talk about how to find these shortly.

There’s a point of diminishing returns. If a 1,000-word blog post contains 30 internal links:

  1. Each one carries very little individual weight
  2. The page looks spammy to readers
  3. It becomes genuinely hard to read

Quality over quantity, always.

This sounds obvious, but I’ve 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.

There’s no magic number. Google’s John Mueller has said repeatedly that there’s no specific limit. The old “100 links per page” guideline from years ago is outdated and was never a hard rule.

Here’s a better way to think about it:

Page Type

Typical Word Count

Contextual Internal Links

Notes

Blog Post

1,500-2,500 words

3-10 links

Not counting nav/footer links

Service Page

500-1,000 words

2-5 links

Focus on related services and case studies

E-commerce Category

200-500 words

20-200+ links

Mostly to products and subcategories

Pillar Content

3,000+ words

10-20 links

Links to all supporting articles

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’re adding the link purely for SEO purposes and it interrupts the reading experience, question whether it belongs.

This is worth going into some detail on, because anchor text strategy for internal links is different from external link building.

Types of anchor text and when to use them

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 a page uses the identical phrase, it starts looking manufactured.

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 audit and fix common internal linking mistakes?

Knowing what to do is only half the battle. You also need to know what’s currently broken. Here’s how to audit your internal links.

  1. Screaming Frog SEO Spider. This is my go-to tool for technical audits. The free version crawls up to 500 URLs, which covers most small to medium Irish business websites. Run a crawl and you’ll 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.
  2. 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.
  3. Google Search Console. Free and already set up for most sites. The Coverage report shows you which pages Google has indexed and which it hasn’t (and why). The Links report shows you which pages on your site receive the most internal links.

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’re running.

Internal linking for service-based businesses

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:

  1. Your service pages are hubs
  2. Every relevant blog post should link back to the appropriate service page
  3. Writing about the process of buying a house? Link to your conveyancing service page
  4. 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:

  1. Relevant blog posts that support your expertise
  2. Case studies demonstrating success
  3. Client testimonials
  4. FAQ pages answering common questions

Internal linking for e-commerce sites in Ireland

E-commerce internal linking is a different beast. You’re dealing with potentially hundreds or thousands of product pages, category pages, filter options, and sorting parameters.

Key strategies for e-commerce:

  1. Category pages to product pages is the foundational link structure
  2. Every product should be reachable from its parent category within one click
  3. Products should link to related products (“customers also bought,” “you might also like”)
  4. Link from products 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: 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. Use canonical tags, robots directives, or parameter handling in Search Console to manage this.

Internal linking for blogs and content sites

If your site is primarily content-driven – think news sites, niche blogs, or media publications – your internal linking strategy revolves around topic clusters.

The key for content sites is ongoing maintenance:

  1. When you publish a new article, add links to it from relevant older articles
  2. Don’t just link FROM new content TO old content
  3. Go back to those older articles and add a link to the new one
  4. Those older articles have had time to accumulate authority and backlinks
  5. A link from them to your new content is valuable

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 isn’t a “set it and forget it” job.

Basic internal linking suggestions

Here’s a practical checklist you can work through. Don’t try to do everything at once. Pick the first two or three items, complete them, then move on.

  1. Audit your current internal links
  2.    
  3.    Run a Screaming Frog crawl or Ahrefs Site Audit
  4. Identify orphan pages, broken links, and redirect chains
  5. Export the data so you have a baseline
  6. Identify your 10 to 15 most important pages
  7.    
  8.    Write them down
  9. These are your money pages, best-performing content, and core service/location pages
  10. Every one of these should have strong internal link support
  11. Create or update a hub-and-spoke topic cluster structure
  12.    
  13.    Map out your pillar topics and supporting articles
  14. Draw the connections
  15. Then build the links
  16. Review anchor text quality across the site
  17.    
  18.    Replace generic anchors (“click here,” “read more”) with descriptive alternatives
  19. Vary your anchor text so it looks natural
  20. Fix broken internal links
  21.    
  22.    Every 404 link should be either updated to point to the correct URL or removed entirely
  23. Set up 301 redirects for any pages you’ve deleted or moved
  24. Ensure location pages link coherently
  25.    
  26.    If you serve multiple Irish cities or counties, check your location page links
  27. They should link to each other and to relevant service pages in a way that makes sense
  28. Add contextual links in blog posts
  29.    
  30.    Go through your most recent and most popular blog posts
  31. Add 2-3 internal links to relevant service pages, pillar content, or related articles
  32. Then do the same in reverse: update older posts to link to newer content
  33. Re-crawl after changes
  34.    
  35.    Run another crawl to confirm the improvements
  36. Check that orphan pages are now linked, broken links are fixed, and priority pages have more internal links

This isn’t 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?”

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.

There’s 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’s there only for SEO manipulation, leave it out.

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.

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’s 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’re 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.
