Internal Linking Explained Simply
Internal linking, the practice of linking from one of your own posts or pages to another, is one of the simplest SEO habits you can build, and one of the most skipped. It costs nothing, takes seconds per post, and genuinely helps both readers and search engines.
What internal linking actually does
Every link on your site tells two different audiences something useful. For readers, it says “if you liked this, here’s something related you might want next,” keeping them on your site longer instead of bouncing back to search results. For search engines, it maps out how your content connects, which helps them understand what your site is about and which pages you consider important enough to link to repeatedly.
A blog with zero internal links looks, from the outside, like a pile of disconnected pages. A blog with thoughtful internal links looks like an organized library where everything points somewhere useful.
The rules that actually matter
- Only link when it’s genuinely relevant. Don’t force a link into a sentence where it doesn’t belong just to hit a number. Readers notice, and so does the flow of your writing.
- Use descriptive anchor text. Link the words that actually describe the destination, like “our guide to choosing a blog name,” instead of a vague “click here.” Descriptive anchor text helps both readers and search engines understand what they’ll find on the other end.
- Link in both directions over time. When you publish a new post, link back to relevant older ones. Just as importantly, go back and add a link from those older posts forward to the new one. New content rarely gets linked to automatically; you have to do it.
- Don’t overdo it. A handful of genuinely useful links per post is plenty. A paragraph with five links crammed into it is harder to read, not more helpful.
A quick before-and-after
Weak: “If you want to learn more about this, click here.”
Better: “If you haven’t settled on a name yet, our guide to choosing a blog name walks through the whole process.”
The second version tells the reader exactly what they’re clicking into before they click, which builds trust and improves the odds they’ll actually follow the link.
Finding linking opportunities in what you’ve already written
Internal linking isn’t just something you do while writing a new post. Some of the best opportunities live in your archive. A simple process:
- Search your own site for a topic related to a post you just published.
- Skim older posts that mention the topic, even briefly.
- Add a natural link from that older post forward to your new one.
- Do this for two or three older posts each time you publish something new.
This habit pairs naturally with reviewing and refreshing your archive, which is exactly what How to Update Old Blog Posts covers in more detail.
A realistic target
There’s no strict rule for how many internal links a post needs. A useful rough guideline for a typical blog post is two to five internal links, spread naturally through the piece rather than clustered in one paragraph. If a post genuinely doesn’t have a relevant related post yet, don’t force one. Just make a note to link back to it once you write something that fits.
