I have set up my google merchant account a few days ago and I tried to add my first product and it got disapproved but after a few hours I can see the following message on my account: "Account isn't eligible for enhanced listings on surfaces across Google" Anyone has faced the same issue and how did you guys solve this.
Thanks in advance.
Make sure you fulfill all requirements. I have written a great article explaining this here: https://feedarmy.com/kb/requirements-for-enhanced-listings-on-surfaces-across-google/
You do still need to follow all other policies. My article only covered enhanced listings.
Here is a full checklist: https://feedarmy.com/kb/google-shopping-before-you-start/
That is correct. Enhanced listings is currently only in the US. But may change at any time.
The requirement is to target the US, you do not need to have your business in the US.
Poor or no performance can be due to a lot of reasons, carefully inspect your data feed, and campaign setup.
Check your website quality and setup.
