Hey guys, I have an issue with one of my clients fb account : He gets send trash traffic I mean terrible traffic, his ad is a video ad to a free course, great CTR (over 7%) but once they're on the page no optins over 700 visits (and we've tested, it's not a technical issue) We think it's because one of his past landing page had a technical issue, facebook noticed it was a "bad customer experience" and now sends trash. I've tried from another ad account inside the same business manager but same issue. Any advice? Should we try from another BM ?
