Three days. That's how long it took for my inbox to fill with 47 emails from clients all asking the same question: "Wait, is it Data Studio or Looker Studio now?

Facebook told us we drove 100 sales from a campaign. GA4 said we drove 10. Same campaign, same week, same product. And my CMO wanted to know which number to put in the board deck.

Our CRM recorded 1,847 signups in Q1. GA4 showed 1,204. That's not a rounding error. That's a 35% gap that went unnoticed for nearly six months, quietly distorting every marketing decision we made.
We were celebrating a 340% ROAS on a paid social campaign when our CFO asked a question that made the room go quiet: "Why did revenue only go up 6% if this campaign performed so well?" That single question kicked off a two-week audit that uncovered something ugly.

I've watched marketers panic over a 73% bounce rate on their blog while completely ignoring a 52% bounce rate on their pricing page. They had it exactly backwards. The blog was performing beautifully. The pricing page was bleeding revenue.
We spent $40,000 on a Q1 campaign that our dashboard said was generating a 4.2x return. High fives all around. Then someone on the finance team asked why revenue didn't actually go up. Turns out, a misconfigured UTM parameter was double-counting conversions from organic search as paid conversions.
