Case #031: The default settings that quietly taxed me 30%
New traffic source, new platform. I launched on the out-of-the-box settings — automatic placements, broadest optimization, accept-all targeting. $110/day on a gaming offer. ROI limped at -12% and I assumed the source was just weak.

Then I read the placement report I'd been ignoring. The platform's "automatic" placement was dumping 40% of my budget into a low-quality network of parked domains and content-farm widgets that the platform bundles in by default. Real users converted. The default bundle converted at a tenth the rate and ate nearly half my spend. The platform wasn't weak. The defaults were designed to spend my money on their cheapest inventory.

The fix: on any new source, the first thing I do now is open every default setting and turn off everything that says "automatic," "recommended," or "expanded" until I've manually chosen what's on. Defaults serve the platform's fill rate, not my ROI.

I stripped it to hand-picked placements only, killed the bundled junk network, and tightened the targeting myself. $1,500 spent, $2,250 back. 50% ROI from the same source I'd written off as a dud.

— The lesson: a platform's default settings are optimized for the platform's revenue, not yours — untick everything that says 'automatic' before you spend a dollar.
