LINKS · SEO GLOSSARY
Internal Linking
Links between pages on the same domain that distribute PageRank, establish site hierarchy, and guide crawlers to important content.
Definition
Internal linking is the practice of linking from one page on a domain to another page on the same domain using anchor text. Internal links serve three purposes: they pass PageRank (link equity) from pages with high authority to pages that need it, they signal to crawlers which pages are most important, and they establish the information architecture that tells users (and search engines) how the site's content is organized.
Why it matters for SEO
Orphan pages — pages with zero internal inbound links — are rarely crawled and almost never rank well. Crawlers discover pages by following links; a page that no other page links to may only be found via the sitemap, and even then may receive minimal crawl budget. At the other end, hub pages that receive many internal links inherit higher PageRank and tend to rank for their cluster's primary queries. The anchor text of internal links also carries semantic weight — descriptive anchor text is a relevance signal.
How DeepSEOAnalysis checks this
The audit maps internal links between all crawled pages and flags pages with zero inbound internal links (orphans) as a warning. It also flags pages with very few inbound links relative to the rest of the site, excessively deep click depth (buried more than 4 clicks from the homepage), and broken internal links (pointing to 404 pages) as critical issues.
