Side by side
These rows come from Google's comparison table on the Demand Gen help page.[1]
| Demand Gen | Performance Max | |
|---|---|---|
| Purpose | Generate demand and results on Google's most visual surfaces | Maximize performance across all of Google's channels |
| Channels | YouTube (Shorts, in-feed, Home, watch next, Search), Discover, Gmail, Display Network. You can choose. | Search, YouTube, Discover, Gmail, Display Network, Maps. Google chooses. |
| Audience | Target segments you choose, including lookalikes | No hard targeting; audience signals and goals steer it |
| Bidding goals | Clicks, conversions or conversion value | Conversions or conversion value |
| Formats | Image, video, carousel (2 to 10 cards), product feeds | Text, image and video assets in asset groups |
The real difference: who is in control
Both campaigns use Google AI. The difference is how much you steer it. Demand Gen lets you choose the channel (a vertical video can run on Shorts only), choose the audience segments, and run A/B experiments on creative.[1] Performance Max takes a goal and assets and decides channel, audience and bid for you.[2]
That makes Demand Gen the better test bed for creative and audiences, and Performance Max the better tool for spending a budget against a conversion goal with less setup.
Who sees the ads
Performance Max can show on Google Search, so part of its spend reaches people who are already looking for what you sell. Demand Gen cannot show on Google Search results pages; its people are scrolling YouTube, Discover or Gmail. Expect Demand Gen to have a lower conversion rate and, often, a lower cost per click. Neither number alone tells you which is working. Compare cost per conversion, and for Demand Gen allow for a longer path to purchase.
When both run in the same account, Google settles overlap by Ad Rank: the campaign with the higher Ad Rank serves.[3]
Budgets and bidding
- For Demand Gen with target CPA bidding, Google recommends a budget of at least 10 times the target CPA.[1]
- For both, Google's budget panel suggests up to three daily budgets and calls the lowest one the minimum recommended.[2]
- Demand Gen can bid for clicks, which helps a brand-new account with no conversion data. Performance Max always bids for conversions or value.[1]
- When purchases are rare, Google suggests Demand Gen optimize to lighter events such as add to basket.[1]
Which to choose
- Pick Demand Gen if you sell something people don't search for yet, you have short-form video or strong images, and you want to test creative and audiences.
- Pick Performance Max if you have a product feed or steady leads, reliable conversion tracking, and want one campaign covering Search and the rest of Google.
- Run both once each has enough budget to learn. Give Demand Gen its own budget so Performance Max's search conversions don't make it look weak by comparison.
