I've read every sitemap issue thread I could regarding "couldn't fetch". To summarize the solutions:
Those did not work for us. After a lot of mucking with the system I've finally got the sitemap.xml file so it now contains all four categories (pages, blogs, collections and products). Sidenote: when I created my first page it kept putting it in https://jindosofla.myshopify.com/sitemap_pages.xml instead of https://jindosofla.myshopify.com/sitemap_pages_1.xml. Not sure if that matters. But the main sitemap only contained https://jindosofla.myshopify.com/sitemap_pages_1.xml which had no pages at the time. In any case its in what I assume is the right place now.
We are using the default shopify subdomain, jindosofla.myshopify.com, and not a custom domain. We are still getting this error in GSC:
Here is our sitemap: https://jindosofla.myshopify.com/sitemap.xml
Here is the products sub sitemap: https://jindosofla.myshopify.com/sitemap_products_1.xml?from=4252921987119&to=4364195233839
We have 100 products listed in our products sub sitemap, could that be the issue why it can't fetch? Is that too many?
Solved! Go to the solution
The number of products is not an issue. 100 is little. Have clients with far larger SKUs that we're able to submit sitemaps for with no problem.
Of the 100s of sitemaps I've submitted as part of Google Analytics or SEO work, we've never submitted one for a store with a myshopify.com domain. So I don't know if using that myshopify.com is the problem, but it is otherwise not recommended if you're serious about looking serious. Using a custom domain, setting that up in GSC, then submitting a sitemap for it may fix it.
This is an accepted solution.
Ah yes thanks both of you.
That indeed solved the problem. The sitemap can now be found by google. For anyone else experiencing this issue - you need your own domain. The default shopify subdomain will not integrate with Google Search Console. Also added a blog post, page, etc.
