Those that submit products through Google Merchant Center to be shown on Google Shopping/Google Product Search can now submit feedback to Google for issues and feature requests.
Ronald from the Google team posted a thread at the Google Merchant Help forum asking for feedback. He said:
Hello Google Merchant Center Users,
Beginning this week, we are initiating a new exercise to collect your opinion, feedback and suggestions to improve the Google Merchant Center. I will start a discussion thread on every Monday on a particular section of the Google Merchant Center. One of our team members will respond to the thread at the end of the week.
This week's topic is "Account settings." Please let us know what you like or dislike about the Google Merchant Center account settings, what else you would like to see in this section.
Please do take sometime and provide us with your valuable feedback.
Merchants have already taken the time to submit some feedback to Google, so why don't you do the same?
Also, Ronald noted in another thread that removing the file or metatag you added to your website as part of the verification process will result in losing your "verified" status and will need to go through the verification and claiming process again.
So submit your feedback!
