Backlinks help the system trust your site. Internal links tell the system what matters and where each page belongs. This explains how internal linking affects indexing/retrieval, why many sites misinterpret “authority”, and the architecture patterns that reliably move pages into visibility.
Topic clusters are not a “content hack”. They are a way to make intent coverage legible: a small set of related pages that reinforce each other through hierarchy and links. This explains what a topic cluster is, how search engines interpret clusters, why most clusters fail, and how to validate outcomes in GSC.
Orphan pages are URLs with no meaningful internal links pointing to them. This guide shows how to detect orphans (crawl + GSC + sitemaps), what to do with them (link, merge, noindex, or remove), and how to validate the fix.
