i lost $4k on an influencer collab because i only checked follower count
Ran a paid collab last year with a creator at 180k followers on X. Engagement rate looked fine on paper. Posts converted basically nothing.
When I went back and actually scrolled the comments, the same 15 accounts were replying to every single post. It was a co-engagement pod. Real people, real accounts, but a tiny circle inflating each other's numbers. None of them were remotely in our target demo.
The other red flag I missed was the timing curve. Their "viral" posts got 80% of likes in the first 45 minutes then completely flatlined. Organic content doesn't behave like that.
Since then I've changed how I vet. I look at 90 days of posting history instead of a highlight reel, I check whether the audience actually overlaps with my buyer, and I pay way more attention to who is engaging rather than how many. The whole process takes longer but it's saved me from repeating that $4k lesson.
Still figuring out the best workflow for this honestly. Spreadsheets and manual scrolling only scale so far.
