Internal linking is how the pages on your own site point at each other. It is the least glamorous item on any SEO checklist. It is also one of the very few you control completely, with no outreach, no budget, and nobody else’s permission required.

What Is Internal Linking?

An internal link goes from one page on your site to another page on the same site. An external link points somewhere you do not own. That is the whole distinction.

A standard crawlable internal link helps search engines discover the destination and understand its context. It also gives readers an obvious next step while they are already interested in the topic.

Why They Matter More Than People Think

Unlike links from other websites, internal links are entirely yours to place. They are one of the most accessible ways to improve navigation and help search engines understand how your content fits together.

A page with no internal links pointing to it is an orphan. Search engines may still discover it through a sitemap or an external link, but readers cannot reach it through your site’s own links. Internal linking also helps show which pages are related and important within your site.

Cyrus Shepard’s Zyppy team studied 23 million internal links across roughly 1,800 sites, matched against Search Console clicks. Pages with at least one exact-match anchor pointing at them had over five times the traffic of pages without. Variety mattered too. The more distinct phrases pointed at a page, the more traffic it tended to get. That is correlation, not proof, and the study says so itself. It is still the right direction to aim in.

How to Do It Well

  1. Describe the destination in the anchor text. Use wording that tells readers what they will find. Exact-match text can be natural, but do not cram keywords into anchors.
  2. Let the wording vary naturally. Different sentences will call for different anchor text. Clarity matters more than following a fixed exact-match formula.
  3. Link from your strongest pages, not just your newest. Most people add links going forward and never revisit. The bigger win is usually opening an old post that already gets traffic and pointing it at something newer.
  4. Give every new post useful connections. Add links to older pages when they answer a likely follow-up question. Use relevance, not a quota, to decide how many.
  5. Do not force it. A link the reader would not want is just noise. Google does not publish an ideal number of links per page, so add as many as are genuinely helpful and keep the page easy to use.
  6. Go find your orphans. Crawl the site and list every page with nothing pointing at it. Fix the ones you actually care about. It is a slow afternoon, and usually the highest-value linking work available.

WordPress users can try a plugin like Link Whisper, which scans your posts and suggests places a link would fit. The suggestions need judgment applied, but it beats searching your own archive by memory.

RightBlogger can pull internal links from your connected site while it drafts, so new posts arrive already pointing at relevant older ones instead of needing a manual pass afterwards.

The Short Version

Internal linking takes a couple of minutes per post and compounds for years. Name the destination clearly in the anchor, link from strong pages as well as new ones, and go rescue whatever is sitting there with nothing pointing at it.
