Sites are re-measured as the crawler comes back around to each city, so a redesign or a technical fix shows up in the score. Agencies that claim their profile can also submit corrections, which our team reviews before anything goes live.
Listing is automatic: the crawler finds agencies from public search results, so there is nothing to buy. To manage a listing, open your profile and claim it with an email on your own domain. That unlocks a dashboard with profile analytics, quote requests, editable details and an updates feed.
