Internal links are the cheapest rankings you can buy, because you are not paying in money — just a few minutes per page.
Why they matter
- They spread authority from strong pages to pages that need it
- They help search engines discover and understand your pages
- Descriptive anchor text tells search engines what the target is about
- They keep users on site longer
Rules of thumb
- Link from high-traffic pages to pages you want to rank
- Use descriptive anchors, not "click here"
- Keep it natural; a handful of contextual links per article
- Fix broken internal links so you do not waste crawl budget
Build topic clusters
A pillar page links to related sub-pages, and each sub-page links back to the pillar. This makes topical coverage obvious to search engines.
Audit it
Paste a page's HTML into the free link extractor to list all internal and external links, spot broken ones, and see which pages you are sending authority to.
