How many internal links should a page have?

There is no magic number. The useful test is whether every important page is reachable in a few clicks from the homepage and receives links from related content. Pages with no internal links pointing to them are effectively invisible regardless of how good they are.

Do internal links really affect rankings?

Yes, and they are the most under-used lever most sites have. Internal links distribute authority, signal which pages matter, and give search engines context through anchor text. Unlike backlinks, they are entirely within your control.

On-Page SEO

Internal Link

An internal link is a link from one page on your site to another page on the same site.

Internal links pass ranking signals between pages, help search engines discover content, and guide users deeper into the site. A deliberate internal linking structure is one of the highest-leverage and most underused SEO moves, because it costs nothing and you control it entirely. For example, linking a blog post to the relevant service page channels relevance toward that service.

The pages most in need of internal links are the ones hardest to notice, because nothing about them looks broken. A crawl that reports inlink counts finds them quickly: sort by fewest incoming links and the orphaned and near-orphaned pages surface immediately. These are often exactly the pages that matter, since service pages tend to be linked once from navigation while blog posts accumulate links naturally. Adding contextual links from relevant existing content is one of the few SEO changes that costs nothing, carries no risk, and takes effect on the next crawl.

Example

A crawl shows a conversion-rate-optimisation service page receiving exactly one internal link, from a footer menu, while twelve blog posts about landing pages and testing never mention it. Adding one contextual link from each post gives the page thirteen relevant votes. It moves from page three to position six over the following six weeks, with nothing else changed.
