"Normal" performance on the 50 accounts we monitor as well. Over the last fortnight, nothing spiking or tanking in any direction - just flat delivery across the board.
For context, I've been cross-referencing this with Search Console and Ahrefs for organic bleed, plus the usual Meta Business Suite breakdowns. If I had to put a number on it, CPA is sitting within ±8% of the 90-day average, which for this time of year is about as steady as it gets.
One thing I have noticed: the usual Tuesday/Wednesday volume spike has been a lot flatter than usual. Might be worth checking if anyone else is seeing the same plateau mid-week.
Are you seeing any shift in auction dynamics or is it just same-old same-old?
