Many people spend their energy chasing links from other websites, while one SEO tool sits entirely in their own hands and often goes ignored: internal links. An internal link points from one page of your site to another page on the same site. For a search engine it is a path for discovering pages and a hint about which pages relate to each other. For readers it is a signpost to what to read next. A good structure costs nothing, only planning.

Search engines find new pages mostly by following links. A page that has no incoming link from any other page on the site, called an orphan page, is hard to discover and gets visited less. Internal links also show how topics relate: if many articles about keyword research point to one main guide, it is clear to a search engine that this guide matters to your site.

For users, the right link answers the next question before the reader has to search for it. Readers who find a useful follow-up tend to stay longer on the site, which is good for everyone.

Good Anchor Text

Anchor text is the clickable text. Write words that describe what the destination page is about, such as "keyword research guide", rather than "click here" or "read more". Descriptive anchors give context to readers and search engines alike.

Vary them naturally. There is no need to use the exact same keyword in every link, and forcing it feels contrived. Let links flow within the sentence the way a human writer would place them.

Also make sure links use the right HTML element: an a tag with an href attribute. A link that is only a JavaScript button without an href may not be readable by crawlers.

Structure with Main and Supporting Pages

A practical way to think about it is as clusters of topics. One main page covers a broad topic thoroughly, and several supporting pages cover sub-topics in depth. The main page links to each supporting page, and each supporting page links back to the main page and to relevant siblings.

For example, a complete guide to SEO can be the main page, while dedicated articles on backlinks, keyword research, and local SEO act as supporting pages. This pattern gives a clear reading path and shows how deeply you cover the subject.

  1. List all your important pages. Decide which pages are priorities, such as product pages, services, or the main guides.
  2. Look for opportunities in existing content. When writing a new article, link to relevant older ones. Then go back to the older articles and link to the new one.
  3. Place links within the content. A link inside a relevant paragraph is usually more useful than a long list at the bottom.
  4. Use navigation and breadcrumbs. Menus, breadcrumbs, and related-article lists keep structural links consistent.
  5. Keep the number reasonable. There is no magic figure. The test is usefulness: link when it genuinely helps the reader.

Find orphan pages by comparing the list of URLs in your sitemap against the results of a site crawl from an audit tool such as Screaming Frog or similar. URLs that are in the sitemap but never reached through links need to be connected.

The Links report in Google Search Console shows which pages receive the most internal links. Check whether the pages you consider important are really there. If a strategic page has only a few incoming links, add some from relevant pages.

Also watch for broken links that lead to 404 pages. Fix them by updating the link target, or set up a 301 redirect if the page has genuinely moved. Long redirect chains should be shortened so links point straight to the final address.

Common Mistakes

  • Using generic anchors like "read more" on every link.
  • Linking every page to every other page, so no priority can be read from the structure.
  • Leaving important pages reachable only through internal search or forms rather than ordinary links.
  • Linking to different versions of a URL, for example with and without a trailing slash or with tracking parameters, when the page is the same.
  • Never updating old articles after new content is published.

Wrapping Up

Internal links are not glamorous, but the payoff is real because you control them completely. Start by listing your most important pages, find orphan pages, then add links with clear anchors from existing content. Make it a habit: a new article is not finished until it links to related articles, and older articles are updated to link back to it.
