Demand gen campaigns
Demand gen campaigns were initially created to capture engagement and awareness across YouTube, including Shorts, Discover, Gmail, and Google video partners.
Over the last few years, Google has continuously looked at the demand gen campaign as something that can become bigger and more should be a part of every advertiser’s media plan. This is becoming a key campaign for capturing initial demand and creating an initial impact on the user’s mind.
It now allows advertisers to have their messages appear across most visually appealing inventory. It also allows you to customise your ads to suit specific inventory. You can have videos for YouTube, image and carousel ads for Discovery Network, and headlines and descriptions on Gmail inventory.

The most recent update from Google is that we will not be able to create YouTube video action campaigns anymore. It will be there for a few more months; however, after July 2025, we won’t be able to do it. Existing Video action campaigns will get upgraded to demand gen campaigns. I think one of the primary reasons Google is doing this is to consolidate the number of campaigns and let advertisers have more control over where their ads are appearing.
Just to keep it short, Demand gen campaigns provide engagement opportunities across YouTube inventor. This campaign allows you to target an audience based on their interests, behaviours, and demographics.
Demand gen campaigns are a great medium for achieving brand awareness, engagement, and lead generation. They allow you to use interactive content, eye-catching visuals, and short-term videos.
This campaign type should be used for brand launches and brand lift studies.
