An internal link is a link from one page on a website to another page on the same site.
Internal links help visitors find related pages and help search engines discover pages and understand which ones matter most.
Pages with no internal links pointing to them are hard for search engines to find and tend to rank poorly.
Why it matters for a launch
Linking your blog posts, docs and feature pages to each other spreads the value of the backlinks you earn across the whole site.
