Internal links help people and crawlers discover useful content.
Why this matters
A good link connects related ideas. Link a glossary definition to a tutorial that uses that term, or a general guide to a more detailed troubleshooting article. Avoid creating hundreds of near-identical links solely to influence a score.
Example and interpretation
A website audit might flag an orphaned article that exists in the sitemap but is not linked from any relevant page. Adding a link from a related guide improves discoverability and gives visitors a meaningful next step.
What to do next
Start with your five most important pages. Make sure each is reachable through the navigation or a relevant hub page. Recheck broken URLs after moving or renaming articles.
