Reviewing how your own pages link to each other is a manageable, high-value task that most sites never get around to doing deliberately.
Check for Orphaned Pages
Pages with no internal links pointing to them are hard for both visitors and search engines to find, and a manual review often surfaces several.
Improve Generic Anchor Text
Replacing vague link text like "click here" with a description of the destination page strengthens the signal for both readers and search engines.
Link New Content Back to Established Pages
Every new page you publish is an opportunity to add relevant links from your strongest existing pages.
Next step: Use the SEO Audit to identify pages with weak internal linking as part of your broader site review.
