CONFIRMED
Internal links pass PageRank
The Myth
"Internal links help distribute link equity (PageRank) throughout your website, helping important pages rank better."
The Truth
This is TRUE and well-documented. Internal links do pass PageRank and help Google understand your site structure and page importance. Strategic internal linking from high-authority pages to important pages can significantly boost rankings. The anchor text used in internal links also helps Google understand what the target page is about. This is one of the most underutilized SEO tactics.
Multiple SEO Tests
Consistent improvements seen when adding internal links from authoritative pages to target pages.
DInsight from @dejanseo
"Internal linking is free and 100% in your control. Most sites massively underutilize this. I've seen rankings jump just from fixing internal link structure. It's probably the highest ROI SEO activity you can do."
