Dear Sir or Madam,
Google shopping Merchant Center ask us to verify that you own the site,
How to uplode the html file to my shop?
so how can we do it?
There is another option underneath that asks you to paste the code in the theme.liquid. Its quite simple.
If you need help setting up PLA's, you can always reach out to me at UriWeinber@gmail.com - it is a service I offer.
