Frequently Asked Questions

What is a good ROAS for e-commerce Google Ads?

The average e-commerce ROAS target is 3-4x (300-400%), meaning for every $1 spent, you generate $3-$4 in revenue. However, this varies significantly by margin a 20% margin business needs 5x ROAS to break even on ad spend, while a 50% margin business can be profitable at 3x. Calculate your breakeven ROAS as 1/gross margin before setting targets.

Should e-commerce stores use Performance Max or Shopping campaigns?

For most e-commerce stores, Performance Max has replaced traditional Shopping campaigns as Google's recommended approach. Performance Max delivers inventory across Search, Shopping, Display, YouTube, Gmail, and Maps with a single campaign. However, brands with strong creative assets and large budgets ($10,000+/month) often benefit from running both to maintain control over placement type and budget allocation.

How much should I budget for e-commerce PPC?

E-commerce PPC budgets depend on your average order value, ROAS target, and competitive landscape. A practical starting budget for new campaigns is $3,000-$5,000/month for Google Ads. Under $1,000/month rarely provides enough data volume for the algorithm to optimize effectively. Scale budgets as you validate positive ROAS at lower spend levels.

How often should I optimize my e-commerce PPC campaigns?

Core optimizations (bid adjustments, negative keyword additions, search term reviews) should happen weekly. Budget pacing should be checked daily. Strategic changes (campaign restructuring, audience strategy, bid strategy changes) should happen monthly based on 30-day performance data. Avoid making multiple significant changes simultaneously isolate variables to understand what drives results.
