Use a product feed to show your products in Discovery ads

An animated example of different placements for Discovery ads with product feeds.

Discovery ads enable you to automatically promote the right products to the right people at the right time as they scroll through their favorite content on YouTube, Discover, and Gmail. This can help you drive purchases from people who might not have been aware of your brand.

If you’re a retailer, you may have a product catalog that you source when it comes to your advertising. Google Merchant Center is a great place to keep that product catalog because it helps millions of people discover, explore and buy products.

Use product feeds with Discovery ads to promote your Google Merchant Center product catalog and to increase sales, leads, or other actions on your website.

Important: On average, Discovery campaigns that are optimized either for sales or lead generation conversion goals, or for both, achieve 45% more conversions at a similar CPA by using product feeds*.
*Source: Google internal data, Global, November 2022. Based on an analysis of 458 advertisers who used product feeds in 731 Discovery campaigns from August to November 2022.


  • Performance: Promote the right products to the right audience at the right moment, reaching potential customers among the 3 billion people on YouTube, Discover, and Gmail. Google machine learning will anticipate a user's interests and intent to automatically show relevant products, helping to meet your max conversions, Target CPA, or Target ROAS (beta) goal.
  • Simplicity: Instead of creating an ad for each item you promote, connect your Discovery campaign to your existing Google Merchant feed. Images and product details in the feed will be used as a large set of creatives for ads that are automatically surfaced to potential customers. Potential customers can select a product image to immediately go to the product’s landing page for more information and to make a purchase.
  • Flexibility: Set and use predefined product group filters to create more targeted Discovery ads.

Note: You will need to set up a new Discovery campaign to link to your Google Merchant Center feed. Adding a Google Merchant Center feed to an existing Discovery campaign isn't supported. You also cannot make changes to a Google Merchant Center feed that's already attached to a Discovery campaign.

Best practices

Use these best practices for optimal results for your prospecting or remarketing campaigns.


Prospecting campaigns

Remarketing campaigns


Prospecting campaigns will help you achieve a range of objectives, from generating site traffic to engagements to sales. Remarketing campaigns typically focus on specific goals such as sales.


Use the custom segments and in-market audiences, and enable optimized targeting to find more potential new audiences. Exclude the previously engaged users to focus on new customers.

Tip: Avoid excluding “all website visitors” as these users may still be your potential new customers.

Include Customer Match and remarketing lists for users who have shown interest in your products or site before.

Tip: If you are looking to measure success for remarketing audiences specifically, then only focus on first-party audiences. If you are looking to expand your audience, consider adding custom segments and in-market audiences.

Product groups

Include as many products as possible that are relevant and are a good match for your selected audiences.

Tip: If your product selection is too narrow, it could impact the ability to serve the most relevant product for each user.

We recommend you include all products from your catalog.

Bids and budgets

  • If hitting a target KPI is your primary goal, use Target CPA or Target ROAS (beta) bidding strategies.
  • Benchmark your KPIs against your social channels, as Discovery ads run on feed-based ad placements with social-like ad formats.
  • Recommended daily budget is 10 times the Target CPA, or expected CPA, or at least $100 USD to $500 USD per day, whichever is higher.

Tip: Just like standard Discovery campaigns, allow 1–2 weeks for your campaign to ramp up.


Assets for product feed ads are primarily populated from your Google Merchant Center catalog.
  • Ad headlines and descriptions: Use your ad-level headline and description to show your storefront or overall offering.
    • Example: “Free shipping on all products” or “10% off storewide”.
  • Intro card: Intro cards are optional. If you supply an intro card, it may appear as an alternative or a fallback when product details cannot be shown.

Google Merchant Center

Use the Google Merchant Center attribute short title [short_title] to power your thumb-stopping product ads.
  • Use quick and snappy titles, which are usually less than 65 characters, that can attract user attention as they browse.
  • Avoid attributes that are specific to product variants, like sizes or gender.
  • We recommend that your most important feed products are represented with square images (1:1) or close to square images (0.6:1.4) for best coverage.
