What you need to know
Internal links help people move from a broad guide to a focused answer. They also communicate how pages relate and which routes are important within your site.
How to apply it
Link from relevant articles using natural anchor text, include a clear path back to topic hubs, and make sure key pages are reachable within a few clicks from navigation or a directory.
Common mistake to avoid
Do not add links that do not help the reader or use the same exact keyword anchor everywhere. Relevance matters more than link count.
