If you want to sell products on Google Shopping, follow this Google Merchant Account setup for your eCommerce store. The Google Merchant Center can be found by visiting google.com/merchants and logging in with the same Gmail account you use to access Google Analytics and Google Adwords.
Once logged in, the Merchant Center will walk you through the set up process. The first steps are entering your store name and website URL. Under contact details, use your name and make sure to add a technical contact if an agency or another member of your team is handling your account. Then click continue.
The next page will ask you to agree with the Terms & Conditions. This is the last part of the initial setup process, and once completed you will be taken to the Merchant Center dashboard. The dashboard is where you can submit a data feed, promotions feed, and more.
Verify your Google Merchant Account
In order to link your new Merchant account to your store, you must verify and claim your website in the Merchant Center dashboard. To do this, click on the Settings link and then click General. Under website URL, use Google Webmaster Tools to verify your website URL. You will be taken to Google Webmaster and will have several choices for verifying your website. We typically verify by linking the Merchant Center with Google Analytics.
Once you have successfully verified your site, return to the General tab under Settings and click I want to claim this website.
At this point, you will now be able to upload your product feed and link your Merchant Center with Adwords. Your Google Merchant Account will sync with your Adwords account – allowing you to set up Google Shopping campaigns.
