Discover Feed

The Discover feed is Google's personalized stream of recommended articles, videos, and other content, and advertisers reach it through Demand Gen. Google lists Discover as one of the channels in Demand Gen campaigns, alongside YouTube, Gmail, and the Google Display Network. You do not buy Discover directly, and you cannot choose it as a standalone campaign type. Ads appear in the feed as image or video units mixed into recommendations, and what decides whether a person sees yours is their interest profile and your creative, not a search term. The feed feels closer to a magazine than a search page, so your ad sits among stories people chose to read.

Because there is no query, targeting is built from signals. In Demand Gen you can use lookalike segments, which Google builds from a seed such as past purchasers, website visitors, or YouTube channel viewers, plus your own data segments and audience signals. Creative includes images in landscape, square, and portrait shapes, text such as headlines and descriptions, video, and carousels. Channel controls in each ad group let you leave the setting on All Google channels, which Google recommends, or choose channels yourself, including Discover. Reporting is available by channel, so you can see Discover's share. Creative variety matters, because the same person may see your ad repeatedly in a feed they open daily.

The settings around it carry consequences. Demand Gen offers goals based on clicks, conversions, and conversion value. For a target CPA, Google says to set a daily budget of at least 10 times the target. Google also advises judging overall campaign efficiency rather than individual channel costs, and notes that to force more spend on one channel you can place it in its own ad group with a higher CPA target, though this may reduce efficiency. Lift studies, including brand lift and conversion lift, are available for measuring what the ads did beyond clicks. Keep the campaign structure simple at first, with one ad group per audience theme, so channel reports stay readable.

The classic error is applying Search expectations. Nobody is looking for you in Discover, so intent is low, click rates are modest, and last-click conversion numbers can look weak. Another is using a thin image library: the feed is visual, and a single banner repeated everywhere underperforms. A third is isolating Discover too early. Channel controls let you split Discover into its own ad group, but that narrows what the system can optimize across, so only do it when you have a reason to test. Also avoid swapping assets daily; the system needs steady impressions before it can compare images fairly.

To work with it this week, open a Demand Gen campaign and check the channel controls for each ad group. Read the channel report to see how much of your spend and conversions came from Discover versus YouTube and Gmail. Upload fresh images in all three shapes and a short video, with a clear first frame and a plain offer. If you cannot judge results from clicks, decide in advance whether you will use a lift study or a simple before-and-after comparison on branded searches. If the feed does not suit your goal, you can turn it off in channel controls and keep YouTube or Gmail.
