Ads kicked in Wednesday, then flatlined Thursday through today. Budget won't deliver, audience targeting is completely off, and zero conversions in 48 hours.
Same pattern every time the algorithm "relearns" - expands to garbage segments, burns through daily spend on junk clicks, then stops spending entirely when it realizes the quality isn't there.
Only thing that's worked consistently: feeding it a tight seed list of actual buyers (intent signals, technographics, firmographics) and letting lookalikes build from that instead of pixel events. Pixel data alone is too noisy at low volume.
If you're running cold with broad targeting, you're just lighting money on fire while the system figures out who isn't your customer.
