ok, so i thought i had the hang of tiktok, right? been pushing a pretty straightforward home goods offer, decent creatives, good targeting. but man, just hit a wall. CPMs shot up like crazy overnight, conversions plummeted. spent the last 3 days trying different angles, new creatives, even flipped my landing page. nothing's working. in fact, i ended up burning more than i made. feels like the algorithm just turned off for me. i know back in the day we could dial in a vert and ride it to the bank, but now it's a total guessing game. just gotta keep testing and hope i find a new angle before my budget's gone. anyone else dealing with these sudden cpm spikes?
