Spent $2,000 on Meta Ads. Got 400 signups and exactly 2 paying customers. What now?

We finally decided to dip our toes into paid acquisition last month. We had $2,000 saved up specifically for a marketing test. I spent a week tweaking the Meta Ads manager, designing creatives, and writing copy.

When the campaign ended, the dashboard looked incredible. We got 400 new signups for our free tier at a Cost Per Lead (CPL) of just $5. I was doing the math in my head, thinking, "If even 10% of these convert to our $29/month plan, we're golden."

Reality hit hard this week.

• Of the 400 signups, 280 never even logged in after creating an account.

• Another 100 logged in once, clicked around for two minutes, and never returned.

• Out of the 20 people who actually connected their data and used the product, exactly 2 upgraded to a paid plan.

I just spent $2,000 to acquire $58 in monthly recurring revenue. Our payback period on this ad spend is basically 34 months, assuming those two users never churn (which they probably will).

I realized the ad was targeting "freebie seekers." The copy promised "Free AI automation" and people clicked expecting a magic wand, not a SaaS tool that requires setup and time. I optimized for the wrong metric (signups) instead of actual activation.

For those who have cracked paid ads: How do you filter out tire-kickers in your ad targeting and messaging?

Did you switch to a "credit card required" free trial to kill the friction? Or did you completely change your ad copy to focus on a specific, high-intent pain point? I'm terrified to spend another dollar until I fix this funnel.
