PMax Conversion Value Tracking
What AdGradr checks
Section titled “What AdGradr checks”AdGradr examines conversion data across all active PMax campaigns, checking not just whether conversions exist but whether conversion values are being passed. This is one of the most important checks for Performance Max accounts.
AdGradr flags accounts with zero conversions despite active spend, accounts where conversions exist but record $0 conversion value, and accounts where conversion values are properly flowing. The severity increases with the degree of missing data. When conversions with values are detected, the report also calculates and displays your PMax ROAS for reference.
Why this matters
Section titled “Why this matters”Performance Max is Google’s most heavily automated campaign type. It runs across Search, Display, YouTube, Gmail, Discover, and Maps simultaneously, letting the algorithm decide where to place your ads. The only way it makes good decisions is through conversion data.
Zero conversions means the algorithm is flying blind. It will spend your entire budget with no feedback on what works.
Conversions without values is nearly as bad. PMax can optimize for conversion volume, but it cannot distinguish between a $50 lead and a $5,000 sale. Without values, the algorithm treats every conversion as equal, often chasing the cheapest, lowest-quality conversions it can find.
What good looks like
Section titled “What good looks like”A well-configured PMax account passes conversion values on every conversion action. For e-commerce, this is typically the transaction revenue. For lead generation, this means assigning values to different lead types (form fills, phone calls, demo requests) based on their average close rate and deal size.
With conversion values flowing, PMax can optimize for revenue, not just volume. This is the difference between “we got 100 leads” and “we got $50,000 in pipeline.”
Common mistakes
Section titled “Common mistakes”- No conversion tracking at all. PMax absolutely requires conversion data. Running it without conversions is spending money with no optimization signal.
- Default $0 values on conversion actions. Google Ads lets you create conversion actions without assigning values. Many accounts leave this at $0 and never revisit it.
- Using “Maximize Conversions” instead of “Maximize Conversion Value.” Without values, you are forced into volume-based bidding, which attracts low-quality conversions.
- Tracking only one conversion type. PMax benefits from seeing the full conversion funnel. Track both micro-conversions (add to cart, form start) and macro-conversions (purchase, qualified lead).
How to fix it
Section titled “How to fix it”- Go to Tools > Conversions. Verify every primary conversion action has a value assigned. For e-commerce, use dynamic values from your transaction data. For lead gen, assign estimated values based on historical close rates.
- Switch PMax bidding from Maximize Conversions to Maximize Conversion Value (with optional Target ROAS) once conversion value data is flowing.
- If conversions show zero after 2+ weeks of spend, debug your conversion tags. Ensure they fire on the correct pages and pass values correctly.
- Add conversion actions for multiple touchpoints in your funnel so PMax has a richer signal to learn from.
When to ignore this check
Section titled “When to ignore this check”PMax campaigns that launched within the past 2 weeks may still be in the learning phase. Google recommends allowing 4 to 6 weeks for PMax to fully optimize, but you should see some conversion activity within the first 14 days if tracking is configured correctly.
