If Google Ads, Meta and your store all show different conversions, your ROAS and CPA are guesses. I fix conversion tracking with GA4, GTM and server-side tagging so every number above matches your real sales.
A good ROAS is any ROAS above your break-even ROAS, which is 1 divided by your profit margin. With a 40% margin you break even at 2.5x, so 3x is profitable. With a 20% margin you need 5x just to break even. Use the Break-even ROAS calculator to find your number.
Divide 1 by your profit margin after product, shipping and fees. If you keep $40 of every $100 sale, your margin is 40% and your break-even ROAS is 1 ÷ 0.40 = 2.5x.
ROAS measures revenue per ad dollar. POAS measures gross profit per ad dollar. Two products with the same ROAS can have very different profit, so POAS shows which campaigns actually make money.
Start from your goal. Divide the number of conversions you want by your conversion rate to get the clicks you need, then multiply by your average CPC. The Google Ads Budget calculator does this for you and gives a daily budget too.
Meta recommends about 50 optimization events per ad set within a week. Multiply 50 by your expected cost per conversion to get the weekly budget, then divide by 7 for the daily budget.
Ad blockers, iOS privacy limits, cookie consent, duplicate tags and different attribution models all cause gaps. Use the Tracking Accuracy checker to measure the gap. Server-side tracking and offline conversion imports are the usual fixes.
