Pete Bowen here. I own GhostBlocker.
I've used Google Ads to generate more than 2 000 000 leads for my clients over the last 17 or so years.
Dealing with spam form submissions has been a constant problem. GhostBlocker comes from the solutions we've developed for identifying and preventing spam - without stopping legitmate leads from converting.
I write about Google Ads and turning Google Ads leads to clients at Pete-Bowen.com.
