Robot.txt Merch suspended due to Google bots cant crawl

I have had my Google Merch account suspended due to Google bots cant crawl majority of my site. This was coming for Google support when I contacted, see below screen shots. I understand certain areas of website does not need to be crawled such as checkout etc… but I see that my collections and blogs have been disallowed for from crawling. I don’t know how to fix this ??

Any advice or help would be grateful!

Blogs and collections are not disallowed, however those with + are by default. There’s some common sense with this as the + in a url would indicate the use of multiple tags to filter a collection so can result in duplicate content. (eg tags of foo+bar is the same as bar+foo).

Do you have the option to open the case again with Google? By default all shops on Shopify share the same starting robots file so it’s not like you’re an outlier.

You could edit it (https://help.shopify.com/en/manual/promoting-marketing/seo/editing-robots-txt), but wouldn’t be a path I would take.

Thanks for your reply Jason.

After chatting with Shopify they said the same that its a default setting. Surely Google deals with a lot of Shopify accounts and they should know this is common. Google advised I need to get my web developer to fix the issue but dont have a web developer and Shopify said I need to fix this issue with Google. There has been no real help from either sides.
