How Google Merchant Center works with Google Ads

Merchant Center holds your products. Google Ads decides where and when they show. One feeds the other.

Merchant Center decides what

  • Stores your product feed
  • Approves or disapproves products
  • Controls titles, images and prices
  • Runs free listings

Google Ads decides where

  • Sets budgets and bids
  • Runs Shopping and Performance Max
  • Chooses which searches you appear on

Your feed becomes your ad

Every line in your feed turns into part of the ad.

A weak feed costs you twice

Messy feed
  • Products disapproved, ads stop
  • Vague titles miss searches
  • Wrong searches waste budget
  • Google Ads can't bid by margin
Clean feed
  • Every product eligible to show
  • Titles match what shoppers type
  • Budget goes to buying searches
  • Custom labels push best sellers

Merchant Center and Google Ads FAQs

Do I need Merchant Center to run Google Shopping ads?

Yes. Shopping ads and product ads in Performance Max pull every product from your Merchant Center feed. Google Ads has no product data of its own.

How do I link Merchant Center to Google Ads?

In Merchant Center, open Settings, then Apps and services, and link your Google Ads account. Accept the request inside Google Ads.

What happens if a product is disapproved?

It stops showing in every Shopping and Performance Max placement until the issue is fixed and re-reviewed.

Does a better feed lower my costs?

Often. Clear titles and correct attributes match you to more relevant searches, so you pay for fewer wasted clicks.
