Over the past month I have started give or take 30 Facebook health/beauty ad campaigns - promoted posts and website click ads - across 15-20 different accounts, business and personal, all with a budget of around $250 per day. The accounts are all matured to $250-500 thresholds.
When the ad is approved we wait for the account to spend a little and activate our redirect. For argument sake, let's say that our avg CVR is around 7% step 1. After 50 clicks we will see our benchmark CVR start to drop 200-250 basis points, sometimes more. When we rotate our presale index our CVR will spike, but then gradually fall again. Our Relevancy Scores range between 8-10, our cpc's hover between $0.06 and $0.12 per click, ad CTR is around 4-7%. My focus is on what would be causing the diminishing CVR across all of our campaigns. This has happened on every campaign we have started for the past month, across all networks. Feedback from networks is that they cannot see what is wrong - no irregular declines, etc.
We have split test pages, offers, networks, servers - we cannot see what we might be overlooking. Any opinions, insight, suggestions are greatly appreciated.
Its seasonal for especially diet, and skin as well.
