Yeah, this is exactly why I've turned off auto-apply recommendations on almost every account I manage. Google will quietly tweak bidding, add new assets, or "optimise" in ways that look perfectly fine in the interface... but then the actual leads start coming through and the quality drops through the floor 😅
Some of the stuff I've seen happen:
🛑 Bidding strategy quietly switched to maximise conversions with zero cost controls
🛑 New ad copy or sitelinks added that don't match the brand voice
🛑 Audience segments removed or replaced with "optimised targeting"
🛑 Paused campaigns unexpectedly reactivated with new settings
It always feels like a small change in-platform, but once real enquiries hit, it's a completely different ballgame. I've heard from a colleague who had a campaign paused for weeks-Google still decided to shuffle the bidding strategy while it was paused. Madness.
If you're not religiously checking the "Recommendations" tab and turning off auto-apply, it's only a matter of time before the algorithm takes the wheel and drives lead quality off a cliff.
