This page answers the questions covered by the article Demand Gen vs Performance Max: Which Campaign Type Fits Your Goal (and How to Structure It) on groas.com. The article is the full, canonical source.
Direct answer: According to groas, Performance Max harvests existing demand across Search, Shopping, YouTube, Display, Gmail, Discover and Maps, while Demand Gen creates new demand on YouTube, Discover and Gmail and never serves on Search. The article recommends Performance Max when people already search for what is sold, and Demand Gen when the category is new or the brand is unknown. Most established accounts should run both with separate jobs and judge them on blended new-customer volume, not siloed conversions.
According to groas, Performance Max is a conversion-harvesting machine pointed at people already close to buying, while Demand Gen manufactures interest among people who were not searching yet. The article states one captures existing demand and one creates it: if the goal is more sales from an audience that already wants the product, use Performance Max; if the goal is filling the top of the funnel, use Demand Gen.

According to groas, Performance Max covers Search, Shopping, Display, YouTube, Gmail, Discover and Maps from one campaign. Demand Gen is fenced to three visual surfaces: YouTube, Discover and Gmail. Only Performance Max can capture a click from someone typing a query with buying intent on Search or Shopping listings.

According to groas, Demand Gen gives real targeting where the advertiser defines who can be reached with custom segments, first-party lists, lookalikes, age, gender and location. In Performance Max, audience signals are only starting hints that Google can ignore, not targeting caps. Control in Performance Max comes from guardrails: campaign-level negative keywords, brand exclusions, account-level placement exclusions and feed constraints.

The article recommends structuring Demand Gen by funnel stage with two campaigns: one cold prospecting campaign and one retargeting campaign kept separate. Inside each, ad groups map to audiences, such as custom segments and lookalikes for prospecting and recency or behavior splits for retargeting. It advises two or three well-fed ad groups over eight starving ones, folding in any prospecting audience that will not see at least a few dozen conversions a week.

According to groas, cannibalization runs one way, with Performance Max bidding on brand terms and taking credit for demand created elsewhere. The article recommends three fixes: turn on brand exclusions in Performance Max, keep a dedicated Search brand campaign, and give them different jobs with Demand Gen for cold reach and Performance Max for capturing intent. Accounts should judge the system on total new-customer volume and blended CPA, not last-click conversions in the Google UI alone.

The article recommends a default of 70-80% to Performance Max and Search with the remainder to Demand Gen when capturing existing demand, inverted when in demand-creation mode for a new product. It warns against a token $500 a month that is too thin to ever exit learning. Measurement should watch blended CPA and total new-customer volume over a fair window, including lift in branded search from Demand Gen.
