What internal links are
An internal link is a link from one page of your site to another page on the same site. Menus, footers, breadcrumb trails, related-article blocks and links inside the text are all internal links. They are the paths visitors use to move around, and the paths crawlers use to discover pages.
Since you control them completely, internal links are one of the more practical levers you have. They cost nothing and need no cooperation from anyone else, unlike backlinks from other websites.
What “passing value” means
SEO writing often says that links “pass value” or “pass authority.” The idea is simple: a link from one page to another is a vote of relevance, and pages that receive more and better-placed links are commonly assumed to be treated as more important. Search engines have described link analysis in general terms, but how much any single link counts is not public and changes over time. Treat the idea as a helpful mental model, not a formula.
Two practical consequences follow. First, a page with no links pointing to it gets none of this attention and may not be found at all. Second, a page that is linked from many relevant places, especially from prominent pages like the home page, sends a signal that it matters.
Links for people come first
The best internal links answer a reader’s next question. If a paragraph mentions a concept that deserves a deeper explanation, a link lets the interested reader go there and the others keep reading. That is a better test than asking whether a link helps rankings. Links added only to push a page will usually feel awkward, and awkward writing is a poor user experience.
Where to put internal links
- In the body text. Contextual links, surrounded by relevant words, are generally the most useful kind.
- In navigation. Menus link to your most important sections. Keep them short, as discussed in the guide on navigation menus and breadcrumbs.
- In hub pages. A page that lists and briefly describes everything on one subject links to each item and gives the cluster a center.
- In related-content blocks. Short lists at the end of an article suggest where to go next.
- From high-traffic pages. If one page gets steady visits, linking from it to a newer or deeper page can help that page get noticed.
Writing good link text
The visible words of a link are its anchor text. Descriptive anchor text tells readers and search engines what to expect at the other end. “Our checklist for moving a site” says more than “click here” or “this page.”
A few guidelines:
- Describe the destination in natural words.
- Vary the wording a little instead of repeating one exact phrase everywhere. Repeating an identical phrase hundreds of times can look mechanical.
- Keep link text reasonably short; a full sentence as a link is hard to scan.
- Make sure link text makes sense out of context, which also helps people who use screen readers.
How many links is too many?
There is no safe maximum, but there is a practical one: a page with hundreds of links makes each link less noticeable and hurts readability. In body text, link when it genuinely helps, and avoid linking the same destination several times in one short passage. A reader scanning an article should not feel they are walking through a field of blue underlines.
Linking and structure
Internal linking is the practical expression of your overall site architecture. If you have organized content into topic groups, linking within each group makes the relationships visible: the overview links to details, details link back to the overview, and related details link to each other. This is often called a hub-and-spoke or cluster approach.
It also affects click depth. Adding a link from a shallow page to a deep one shortens the path, which can make a buried page easier to find and visit. And because pages with nothing pointing to them become orphans, regular checks for those gaps are part of keeping the site healthy.
Common mistakes
- Broken internal links. Links to pages that were moved or deleted lead to error pages. Regular checks for broken links catch these.
- Links through redirects. If a page moved, update the link to point at the new address directly, instead of relying on a redirect chain that adds delay.
- Vague or empty anchor text. Phrases like “here” and “read more” give no context.
- Linking only through menus. Menu links are valuable, but contextual links within content are often where the strongest relevance signals come from.
- Links hidden in places visitors never use. A link that no person would find is not doing its job for visitors.
- Linking to pages you have decided to exclude. Pages marked noindex or blocked from crawling usually should not receive prominent internal links.
- Over-optimization. Cramming exact phrases into every sentence to chase rankings tends to read badly and is not a dependable tactic.
A simple review you can do
- Pick five pages that matter most to you.
- For each, find out which other pages link to it. A site crawler can list incoming internal links.
- If a key page has few or no links, find two or three relevant pages where a link would genuinely help a reader, and add them.
- Check that your newest articles are linked from somewhere sensible, not only listed in an archive.
- Look at whether important pages are linked with descriptive text.
Repeat this occasionally, especially after publishing new material. Results vary and improvements in search visibility cannot be guaranteed, but a well-connected site is easier for everyone to use.
