Hey, @Shawn512 .
Thanks for reaching out and posting this question!
You only need to submit the main file, sitemap.xml, to Google for each of your connected domains and there’s a couple of ways you can do that. After you find the sitemap, you can verify your domain(s) using the following methods:
- Add domain properties and verify your site with Google
- Submit your sitemap file to Google Search Console
That being said, if you prefer more of a guided tutorial, then we’ve also got a video on that here: How to submit a sitemap to Google.
I’d love to hear more about your business! What kinds of products are you selling? Do you have a marketing plan prepared for your store?
