Internal Linking Strategy for Blogs
Internal links connect your blog posts to each other. They help Google understand your site structure, distribute page authority, and keep readers engaged longer.
Why internal links matter
When Google crawls your site, it follows links to discover and understand content. Pages with more internal links pointing to them are seen as more important. Internal links also reduce bounce rate by giving readers a clear next step.
Topic clusters
Organize your blog around topic clusters: a pillar post (comprehensive guide) linked to multiple supporting posts (specific subtopics). Each supporting post links back to the pillar. This signals topical authority to Google.
Where to place internal links
- Within body content where the topic is naturally relevant
- In the introduction when referencing prerequisite knowledge
- At the end as "related reading" or "next steps"
- In H2/H3 section transitions when the topic shifts to something you've covered elsewhere
Anchor text best practices
Use descriptive anchor text that tells readers (and Google) what the linked page is about. Avoid generic anchors like "click here" or "read more." Vary your anchor text — don't use the exact same phrase every time you link to a page.
How many internal links per post?
There's no hard rule, but aim for 3-5 internal links per 1,000 words. New posts should link to existing posts, and you should go back and add links from existing posts to new ones.
How Quillly helps
Quillly has a built-in suggest_internal_links MCP tool. Your AI can analyze your existing blog posts and suggest where to add links in new content — automatically building your internal link structure.
