Catch-all campaigns offer bid coverage for products not included in other campaigns that have inventory filters and custom labels applied. They ensure that 100% of approved products are targeted in your account and capture any new products added to your feed.
Best practices during or after campaign set up
- Create a catch-all Shopping campaign or Performance Max campaign with one 'All Products' product group and a single bid.
- Additional granularity using the Product Type or Google Product Category (GPC) attributes for subdivisions may be applied if the catch-all campaign is targeting a large number of products not broken out in another campaign.
- Choose a bid strategy that is in line with the preferred bid strategy of your Shopping campaign. Google recommends using 'Maximise conversion value' for Performance Max, 'target return on ad spend' for Standard Shopping campaigns that are tracking conversions and 'Maximise clicks' for Standard Shopping campaigns that are not tracking conversions.

- Ensure that the campaign is not budget constrained.
- Set the campaign priority to low (if using Standard Shopping campaigns).
- Do not apply inventory filters or exclusions to the campaign.
Alternatively, you can add any non targeted products in your existing campaigns.
If your primary Shopping campaigns are Performance Max campaigns, we recommend creating a Performance Max campaign as a catch-all campaign with lower budget and higher ROAS target.
