To gauge success, track how your local keyword rankings change over time using tools like Semrush or Ahrefs. Monitor referral traffic in Google Analytics to see if more users are clicking through from specific directories. You can also check Google Business Profile insights to see if your phone calls, direction requests, and website visits are climbing. Watch for overall improvements in your domain authority or trust flow metrics if you’re earning quality backlinks from local listings. Additionally, keep an eye on the consistency of your NAP data with aggregator tools like Moz Local—any downward shifts might signal newly introduced inaccuracies. If you notice a surge in local enquiries or foot traffic, that often indicates your citation-building and local SEO efforts are working in harmony. Adjust as needed, focusing on the directories or listing types that bring in the highest engagement and best-quality leads.
