Why internal linking is important for SEO (and how to do it well)
Internal links are one of the most underused levers in SEO — they shape your site's hierarchy, spread ranking power to the pages that matter, and keep visitors moving toward a sale. Here's how we use them.
Internal linking is the practice of linking from one page on your website to another on the same domain. It matters for SEO because it tells search engines how your pages relate, spreads ranking authority to the pages you most want to rank, and guides visitors deeper into your site toward a conversion. It's one of the highest-leverage, lowest-cost things you can do in SEO.
Most businesses pour effort into content and backlinks and then leave internal links to chance. That's a mistake — a deliberate internal linking structure quietly lifts your whole site. Here's why it works and how we approach it.
Backlinks earn authority; internal links decide where it goes. Point your strongest pages at the pages you most want to rank, and you compound the value of every link you've already earned.
What internal linking is
An internal link connects two pages within the same site — for example, a blog post linking to a relevant service page, or a service page linking back to the homepage. Search engines crawl these links to understand your site's structure and the relationship between pages, starting from the homepage and following the links outward.
Done consistently, this creates a clear map of your site that both Google and your visitors can navigate. Done poorly — or not at all — important pages get stranded where neither can find them easily.
It builds a clear site hierarchy
Sites with strong internal linking have a defined hierarchy: visitors move logically from category to category and find relevant content with ease. Google pays particular attention to the links on your homepage when working out which pages are most important, so the structure you build sends a strong signal about what matters.
A coherent hierarchy also helps Google discover new content faster — a fresh blog post linked from established pages gets crawled and indexed sooner than an orphaned one. If you're publishing regularly, this is how you make sure that work actually gets seen; see our guide to getting pages indexed.
It spreads ranking power to the right pages
Every page accrues some authority, and links pass a share of that authority to the pages they point to. So when a strong, well-linked page links to another page, it lends some of its ranking power. A page that's linked to from many relevant places is treated as more valuable and tends to rank higher.
This is the lever most businesses miss. If you have a high-value service page you want to rank, deliberately link to it from your most authoritative pages and relevant blog posts — you're channelling existing authority exactly where you want results.
It improves user experience (and that helps rankings too)
A well-linked site is simply easier to use. Visitors find related, relevant pages without hunting, which keeps them engaged and moving toward whatever you want them to do next. Good site structure and thoughtful internal links work hand in hand here.
That engagement feeds back into SEO. When visitors move smoothly from page to page rather than bouncing after one, it signals to Google that your site is useful — and useful sites rank better. Internal links are one of the simplest ways to lower a high bounce rate.
How to do it well
- ✓ Link with descriptive anchor text. Use the words that describe the destination page (its target keyword) rather than "click here". The anchor text tells Google what the linked page is about.
- ✓ Link from strong pages to priority pages. Identify your most authoritative pages and point them at the pages you most want to rank.
- ✓ Link every new page in. Whenever you publish, connect it to relevant existing pages — and add a link to it from an established page so it isn't orphaned.
- ✓ Keep it relevant. Only link where it genuinely helps the reader. A link that fits the context adds value; a forced one annoys readers and dilutes the signal.
- ✓ Mind the homepage. Because Google weights homepage links heavily, make sure your most important pages are reachable from it.

Mistakes to avoid
- Generic anchor text. "Read more" and "click here" waste the signal — describe the destination.
- Orphaned pages. A page with no internal links pointing to it is hard for Google and users to find. Every page should be linked from somewhere.
- Over-linking. Stuffing dozens of links into one page dilutes their value and irritates readers. Link with purpose.
- Set and forget. As you add content, revisit older pages to link to the new ones. Internal linking is ongoing, not a one-off.
Internal linking won't make headlines, but it's one of the most reliable ways to get more out of the content and authority you already have. Get the structure right and everything you publish afterwards lands on firmer ground.
Frequently asked questions
What is internal linking in SEO?
Internal linking is linking from one page on your website to another on the same domain. It helps search engines understand how your pages relate, spreads ranking authority to the pages you want to rank, and guides visitors deeper into your site — making it one of the highest-leverage, lowest-cost SEO tactics.
Why is internal linking important for SEO?
Internal links shape your site's hierarchy, pass ranking authority from strong pages to priority pages, and help Google discover and index new content faster. They also keep visitors engaged and moving toward a conversion, and that lower bounce rate signals quality to search engines — improving rankings overall.
What is the best anchor text for internal links?
Use descriptive anchor text that reflects the destination page's topic or target keyword, rather than generic phrases like "click here". The words you link with tell Google what the linked page is about, so relevant, descriptive anchors strengthen the page's relevance for those terms.
How many internal links should a page have?
There's no fixed number — link wherever it genuinely helps the reader and reflects a real relationship between pages. The priority is relevance and purpose over quantity; stuffing a page with dozens of links dilutes their value and worsens the reading experience.
What is an orphaned page?
An orphaned page is one that no other page on your site links to, making it hard for both Google and visitors to discover. Orphaned pages rarely rank well. Every important page should be linked from at least one relevant, established page so it can be crawled and found.
