Hi everyone,
I'm running on Taboola right now and I'm experiencing huge a CPM decrease and CPC increase (using SmartBid) since the past 7-10 days.
To give you an example I had CPCs of around $0.40 before and now I'm paying $0.65-$0.70. CTR decreased drastically, which is of course in direct correlation to the CPC, CPM. Banners I'm using are very similar or even the same. Tried uploading new creatives, totally new images (even gifs, videos), new headlines, tried new offers, new countries but nothing seems to be increasing the CTR - lowering the CPC. CTR is about 2-3x lower than previously which is making the whole campaign unprofitable.
My manager says that they've seen a slight increase in CPCs in the past few days also.
