To gain access to the merchant center account Kliken has created for you, a Gmail-powered email address must be added to the advanced section of the campaign management page. This can be done by going into your account, selecting Manage under Google Shopping Ads, and click the edit button (pencil icon), and then select Advanced, add a Google-powered email address (doesn’t need to be @Gmail.com, just Gmail powered). Example screenshots are available below. After adding your email address you should then receive an email to confirm access.
You can then click the link below to access the merchant account https://www.google.com/retail/solutions/merchant-center/ and sign in with that email address and password. Once in your merchant account, you can review product data and other information from the diagnostics page.
