Demand Gen Campaigns
By the AdFlint research team · Last reviewed July 2026
Serves image and video ads across YouTube, Shorts, Discover, and Gmail using audience segments rather than keywords, inside Google's feed-based browsing inventory.
You load images and video, choose first-party or lookalike segments, and pick a conversion or click goal; Google places ads in feeds people browse rather than search. The type replaced Discovery campaigns and absorbed Video Action campaigns. Advertisers use it to create demand upstream of search. The mistake is expecting search-level intent and cutting it before view-through and assisted effects are measured.
Key takeaways
- Demand Gen Campaigns replaced Discovery Campaigns and absorbed Video Action Campaigns - an account still showing those older campaign types has not migrated or is on inventory Demand Gen has since consolidated.
- Supplying both video and image assets across multiple aspect ratios matters here specifically because the campaign spans YouTube, Shorts, Discover, and Gmail at once; a format gap structurally locks the campaign out of whichever surfaces it can't serve.
- This is a demand-creation channel, not a demand-capture channel - judging it on same-week last-click conversions the way you'd judge Search Campaigns systematically undersells it.
- Check assisted conversions and view-through lift, and segment by asset type and surface, before deciding a Demand Gen campaign isn't working.
In practice.
Demand Gen Campaigns serve image and video ads across YouTube (including Shorts), Discover, and Gmail - all feed-based, browsing-oriented surfaces where people are scrolling rather than searching. The mechanism is audience-first: instead of matching a stated query, you load creative assets, choose first-party audience segments (your customer lists, website visitors) or Google-built segments like affinity and in-market audiences, optionally add lookalike-style custom segments built from your own data, and select a goal (clicks, conversions, or in some setups a value-based ROAS goal). Google then places your ads into people's feeds based on how well the model predicts they will respond, similar in spirit to how Meta's auction scores relevance, but running across Google's browsing surfaces rather than Search inventory.
This campaign type replaced Discovery Campaigns outright and absorbed Video Action Campaigns into a single format, which matters practically because older account structures or documentation referencing either of those names are describing what Demand Gen now does under one roof. If you are auditing an older account, a Discovery Campaigns or Video Action Campaigns line item is a signal the account has not been migrated or is running on legacy inventory that Demand Gen has since consolidated.
Creative format interacts heavily with delivery here in a way it does not in Search Campaigns. Because Demand Gen spans YouTube, Shorts, Discover, and Gmail simultaneously from one campaign, a single asset group with only static images will underperform on video-native surfaces like Shorts, and a single long-form video with no vertical crop will underperform on feed surfaces built around quick scrolling. Supplying multiple aspect ratios and both video and image assets within the same asset group lets Google's system actually compete for the full range of inventory the campaign is eligible for, rather than being structurally locked out of entire surfaces by a format gap.
Advertisers use Demand Gen Campaigns to create demand upstream of search - reaching someone who is not actively looking for a product but is receptive to discovering one while browsing, which puts it in a similar funnel position to Display Campaigns but in materially higher-attention, feed-native inventory that typically costs more per impression. The common mistake is expecting search-level purchase intent from a channel built around passive browsing, then cutting the campaign after a short window because direct conversions look weak. Demand Gen's real value usually shows up as assisted conversions and lift in branded search volume over the following weeks, which a same-week last-click read will not capture.
In reporting, treat Demand Gen the way you would treat Display Campaigns or Video Campaigns run for upper-funnel goals: check assisted conversions and view-through activity, not just last-click, before judging performance. Segment performance by asset type (video versus image) and by placement surface where that breakdown is available, since a campaign blending YouTube in-feed, Shorts, and Gmail into one number can hide that one surface is carrying the results while another is dead weight. If direct conversion volume is the honest goal from day one, that is a signal Search Campaigns or a well-tracked Performance Max campaign is the better tool, and Demand Gen should be evaluated on reach and downstream lift instead.
Reading assisted conversions before cutting a campaign
Suppose a DTC skincare brand runs a Demand Gen Campaign at $1,500/month with a conversion goal, and last-click reporting shows only 8 direct conversions at a $187 cost per conversion - well above their $60 target, prompting a plan to cut the campaign after three weeks.
Checking GA4's assisted conversion path data first, they find another 34 conversions over the same period had a Demand Gen impression or click somewhere earlier in the path, even though a different channel (usually branded search or direct) closed the sale. Counting those as at least partially attributable, the campaign's real influenced cost per conversion is closer to $1,500 / 42 = about $36 - well under target, not over it. This is the specific pattern that makes cutting an upper-funnel campaign on last-click data alone a costly mistake: the channel was working, just not in the position last-click attribution gives credit to.

Common questions.
What happened to Discovery campaigns in Google Ads?
Discovery Campaigns were replaced by Demand Gen Campaigns, which also absorbed Video Action Campaigns into the same format; any account still running Discovery or Video Action campaign types is on a legacy setup that should be migrated to Demand Gen.
Why is my Demand Gen campaign only serving on YouTube and not Discover or Gmail?
This is usually a creative format gap - if the asset group only has video assets in one aspect ratio, or only static images, Google's system may not have eligible creative to compete for Discover or Gmail inventory specifically. Adding both video and image assets across multiple aspect ratios to the same asset group typically opens up the full surface range.
How long should I run a Demand Gen campaign before judging performance?
Give it at least a few weeks beyond the learning period before drawing conclusions, and check assisted conversions and any branded search volume lift alongside direct conversions, since Demand Gen's effect frequently shows up downstream rather than in same-session last-click data.
Can I use Demand Gen for direct response instead of awareness?
Yes, it supports a conversion goal and can drive direct response, but expect intent to be lower than Search Campaigns since people are browsing rather than actively searching; it performs best as a complement to demand-capture channels rather than a replacement for them.
