What if I have already submitted a sitemap previously?
Question: I have already submitted a sitemap. Is it OK to submit another through this app?
Answer: There are no negative effects from submitting another sitemap.
What our app submits to Google is the most up-to-date version of your Shopify sitemap. Each Shopify store has only one sitemap file and this is the same one we submit, we do not create a new file. So while you may not reap the same maximum benefits of a merchant who has never submitted a sitemap, there will certainly be no negative impact. Essentially, we will be submitting the same file you already have, just the latest version of that file.
