Internal links are links from one page on your blog to another. They’re one of the simplest and most underused ways to improve both your readers’ experience and your search rankings. And unlike backlinks from other sites, they’re completely in your control.
Why internal links matter
- Readers find more of your content, stay longer and understand topics more deeply.
- Search engines discover and understand your pages and how they relate to each other.
- Authority flows between pages: a popular post can help newer posts rank by linking to them.
- Your most important pages get signaled as important when many posts link to them.
The basics
Use descriptive anchor text
Anchor text is the clickable text of a link. Make it describe the destination: “our keyword research guide” is better than “click here”. Vary it naturally; don’t use the exact same phrase every time.
Link where it helps the reader
Add links where a reader would naturally want more: a term you mention but don’t explain, a related step, a deeper guide.
Keep it reasonable
There’s no strict limit, but a few relevant links in a 1,500-word post (often 3–8) is typical. Dozens of links in every paragraph become distracting.
A simple system: pillars and clusters
- Pillar posts: your big, complete guides (e.g. “How to Start a Blog”).
- Cluster posts: smaller posts on specific subtopics (“How to Choose a Blog Niche”, “Blog Name Ideas”).
- Link both ways: the pillar links to each cluster post; each cluster post links back to the pillar and to one or two related cluster posts.
This structure makes it obvious to readers and search engines that you cover the topic thoroughly.
A routine for every new post
- Before publishing: add 2–5 links to relevant existing posts.
- After publishing: find 2–3 older posts on related topics and add a link to the new post.
- Link to your pillar post for the topic.
- Check that all links work.
Other places for internal links
- Related posts at the end of each article
- A “Start here” page for new readers
- Category pages with short introductions
- Your About page (link to your best content)
- Breadcrumbs (Home › Category › Post)
Common mistakes
- Orphan posts: posts no other page links to are hard to find.
- Only linking to new posts: older evergreen guides need links too.
- Generic anchors like “here” or “this post”.
- Broken links after changing URLs. Use redirects when you change a slug.
- Linking irrelevant posts just to add links.

FAQs
Should internal links open in a new tab?
Generally no. Readers expect internal links to open in the same tab. New tabs are more common for external links, though either is acceptable.
Can too many internal links hurt?
Only if they hurt readability or look manipulative. Link naturally where it helps the reader.
