Feed issues in Google Search Console and Merchant

In the Google search console, some of my pages are not indexed because they are blocked. Also, in Google Merchant there seem to be some feed issues, and we need to take a close look at the product snippets. I'm looking for a Freelancer who is experienced with Google Search Console, Merchant, Shopify, feeds, snippets, robot text, sitemaps, etc. I know how everything works, but I need somebody with TECHNICAL KNOWLEDGE.
