Merchant Center

Shopping ads and Performance Max product ads are built from Merchant Center data: titles, prices, images, availability. A product that is not approved there cannot be advertised at all.

Product issues are listed in Merchant Center, not in Google Ads, which is why limited or disapproved products are often missed.

1. Open Merchant Center and go to Products.
2. Look at Needs attention for disapproved and limited products, with their issues.
3. Check the link with Google Ads under Settings, then Access and services, then Apps and services.
4. Review the feed's update schedule so prices and stock stay current.

A shop finds 300 products marked limited in Merchant Center because the colour attribute is missing. Adding colour to the feed lets them show in all the places they were held out of.

• Never opening Merchant Center after the first setup.
• Letting prices in the feed differ from the website.
• Ignoring warnings because the products still show somewhere.

The audit checks Oppy runs on this, each with its own page.

• Products that cannot appear at all
• Products held back by something in the feed
• The part of the catalogue that got no impression lately

• Product feed: The file of your products, with titles, prices, images and attributes, that Merchant Center reads.
• Shopping campaign: A campaign that shows product ads with an image, a title and a price, built from your Merchant Center feed.
• Listing group: The way a Shopping or Performance Max campaign divides the product feed, by category, brand or custom label.
