Internal linking is one of the simplest SEO practices, and one of the most useful.It just means linking from one page on your website to another page on the same website. You have seen it many times: a blog post that says “read our guide to keyword research” and links to that guide is using an internal link.
Despite its simplicity, internal linking does a lot of work. It helps readers find related content, helps search engines understand how your site is organised, and helps important pages get discovered. This guide explains how it works and how to do it well, without overcomplicating it.
What Is an Internal Link?
An internal link is a link where both the starting page and the destination page belong to the same website. For example, if your site has a post about gardening and a post about soil preparation, a link from the gardening post to the soil post is an internal link.
This is different from an external link, which points to a different website, and from a backlink, which is a link from another website to yours. Internal links are fully under your control. You decide where they go, what words they use, and how many you include.
Internal links appear in many places: in the body of an article, in navigation menus, in footers, in sidebars, and in lists of related posts. Body links are often the most valuable because they appear in context, where a reader is already thinking about that topic.
Why Internal Links Matter for Readers
The most important reason to add internal links is to help readers. Good links guide people to the next logical step.
Imagine a reader finishes your beginner’s guide to SEO and wants to learn about keyword research next. If you link to your keyword research post at the right moment, you save them a search and keep them on your site. If there is no link, they may leave and look elsewhere, even though you already have exactly what they need.
Internal links also help readers understand a topic more deeply. A beginner may need background information before they can follow an advanced post. Linking back to a simpler explanation makes your content more accessible and more useful.
Why Internal Links Matter for Search Engines
Search engines use links to discover and understand pages. When a crawler visits your homepage and follows links to your posts, it can find content that might otherwise stay hidden. Pages with no internal links pointing to them are sometimes called orphan pages, and they are much harder for search engines to discover.
Internal links also show relationships between pages. If several posts about SEO all link to your main SEO guide, that pattern suggests the guide is an important page on that topic. This does not guarantee a ranking, but it helps search engines understand your site’s structure and priorities.
Anchor text matters here too. Anchor text is the clickable wording of a link. Descriptive anchor text, such as “on-page SEO checklist,” tells readers and search engines what the linked page is about. Vague anchor text, such as “click here,” gives much less information.
A Simple Internal Linking Strategy
You do not need a complex strategy to start. First, identify your most important pages. These are usually your main guides, your homepage, and your key category pages. These pages should receive links from related posts, because they are the pages you most want readers to find.
Second, link related posts to each other. When you write a new post, think about two or three older posts that cover connected topics, and add links to them where they fit naturally. Then, when you have time, go back to older posts and add a link to the new post if it is relevant. This keeps your site connected as it grows.
Third, use a logical structure. A common pattern is a hub-and-spoke model: a main guide links out to more detailed posts on subtopics, and those detailed posts link back to the main guide. For example, a general SEO guide might link to posts about keyword research, on-page SEO, and internal linking, and each of those posts links back to the guide.
How Many Links and What Anchor Text?
There is no magic number, and you should not aim for a specific count. The right number depends on the length of the article and how many genuinely relevant pages you have. As a general guide, a medium-length blog post might include a handful of internal links, perhaps three to eight. What matters is relevance. Every link should help the reader or add useful context. If you have to force a link into a sentence, it probably does not belong there.
For anchor text, keep it specific but natural. Instead of writing “click here to learn more,” write a sentence that includes the topic, such as “our guide to keyword research explains this step in more detail,” and link the relevant words.
Do not repeat the exact same anchor text for every link to a page, and do not stuff keywords into anchor text. Also check that your links still work. If you change a URL or delete a page, update the links that point to it.
Conclusion
Internal linking is simply connecting your own pages in a way that helps people. Link related content, use descriptive anchor text, give your most important pages enough links, and keep your site easy to explore.
You do not need special tools or advanced knowledge to do this well. Start with your next post: add a few thoughtful links to related articles, and then revisit an older post to link forward to the new one. Over time, those small connections build a site that is easier for readers to use and easier for search engines to understand.
