been there done that. The biggest mistake people make when scaling is not analyzing the data properly. Like, yeah, you see some initial growth and think 'cool, I can bump it up'. But most of the time it's just a fluke. So I started breaking down every metric - CPC, CTR, conversions, holdout days, traffic source quality, even time of day. You gotta know exactly what's driving your ROI and what's just noise. One campaign I boosted from 50 to 200 a day and it tanked. Turns out, the traffic quality dipped when I scaled. Switched back to a smaller, tighter source, optimized the lp, and only then added another 100 bucks. Same traffic, different results. It's not just about pushing numbers up, it's about understanding the data behind those numbers. Use split tests, check your drop-offs, re-allocate budget to what's actually converting well. You can't just blindly scale, gotta do it systematically or you'll burn your bankroll fast. YMMV but for me, slow and steady with real data analysis beats just throwing money at the wall.
