A systematic audit of your existing pages against fresh related-term research often reveals easy opportunities to strengthen content that's already live and earning some traffic.
Start With Pages That Are Close to Ranking Well
Content already performing reasonably well is often the best candidate for a related-term audit, since a modest improvement can meaningfully affect its position.
Compare Each Page Against a Fresh Related-Term List
Rather than relying on memory of what a page covers, generate a current related-term list and check the actual page content against it.
Prioritize Additions That Genuinely Improve the Content
Add related terms because they make the page more thorough and useful, not simply because they were missing from the list.
Next step: Use the LSI Tool to generate the related-term benchmark you'll audit your existing content against.
