Do uncrawled but indexed pages affect seo?

[cuarto715]

It's a well known fact that too much thin content can hurt your SEO, but what about when you disallow google to crawl some places and it indexes some of them anyways (No title, no description, just the link)

I am building a shopify store and it's imposible to change the robots.txt using shopify, and they disallow for example, the cart.

Disallow: /cart

But all my pages are linking there, so google has the uncrawled cart in it's index, along with many other uncrawled urls, can this hurt my SEO or trying to remove that from their index is just a waste of time?

-I can't change anything from the robots.txt

-I could try to nofollow those internal links

What do you think?

Hi there!

Yes, pages with poor user experience do affect SEO, even more if those pages receive traffic from google.
So there are two scenaries here, regarding whether they receive traffic:

1. They do receive traffic, either move to other CMS (like wordpress and woocommerce) or improve those pages experience.
2. Do not receive traffic, leave them as is.

Alls this is considering that you are not able to change Robots.txt and do not want to move to other CMS.
Adding nofollow links will not make any difference, because Google does honor the robot.txt, so pages blocked there will not be crawled never. So as to remove them fron index is crucial beind allowed in robots(or what's the sabe, not being disallowed)

Hope it helps.
Best Luck.
