PPC feels more unpredictable lately, is it just me?

I’ve been running different PPC campaigns and it feels like performance swings a lot more than it used to. Even with similar setups, results can change week to week without obvious reasons. I’m curious if others are seeing the same thing or if I’m missing something basic in how I’m approaching optimization.

Many advertisers are noticing more volatility lately, so focusing on tighter tracking, testing creatives frequently, and adapting to platform changes usually helps stabilize results over time.
