Robots.txt file in Shopify - Collection and Product Page Crawling Issue

[HuptechWebseo]

Hi, 
I am working on one big eCommerce store which have more then 1000 Product. we just moved platform WP to Shopify getting noindex issue. 
when i check robots.txt i found below code which is very confusing for me.

**I am not getting meaning of below tags.**

• Disallow: /collections/+
• Disallow: /collections/%2B
• Disallow: /collections/%2b
• Disallow: /blogs/+
• Disallow: /blogs/%2B
• Disallow: /blogs/%2b

I can understand that my robots.txt disallows SEs to crawling and indexing my all product pages. ( collection/*+* ) Is this the query which is affecting the indexing product pages?

Please explain me how this robots.txt work in shopify and once my page crawl and index by google.com then what is use of Disallow:

Thanks.

Make sure products are in your sitemap and it has been re-submitted. You can also submit your products to request indexing for them in Google Search Console.

Thank you for replying,

But, our main issue is that we have already crawled all collection pages but the product pages haven't crawled yet. Now we don't figure out that whether it's robots.txt issue or other crawling issue?

For example: "www.abc.com/collection/" page is crawled but "www.abc.com/collection/product1/" page hasn't crawled.

Please reply me some tips here.

While you may not want context indexed, it's still valuable to be crawled and access your most important content like products.

If you are blocking your /collections pages, Google will not be able to see that page's meta robots set to noindex, causing an issue for you. You may consider allowing robots to crawl your /collections pages but noindex them if they are low value or duplicative.
