30-40% invisible conversions = massive wasted spend and broken algorithm optimization.

30-40% data loss typical. $10K/month ads = ~$3K wasted monthly on misattribution. $50K/month = $15K wasted. Missing conversions train algorithms wrong, causing poor targeting and overspend on 'losers' that actually work.
