Google is requiring Google merchants who submit their products to Google Product Search to verify and claim their website URL. This step is meant to verify that merchants have the right to upload their product listings for the website they are advertising.
When you log in to your Google Merchant Center, you should notice the message: “From May 18th, you will not be able to submit any product listings unless you have previously claimed your Website URL”
Verifying your website will only take a few minutes. Here are Google’s Instructions on how to complete this verification process.
