Hi,
I'm working with a Shopify site that has about 10x more URLs in Google's index than it really ought to. This equals thousands of urls bloating the index. Shopify makes it super easy to make endless new collections of products, where none of the new collections has any new content... just a new mix of products. Over time, this makes for a ton of duplicate content.
My response, aside from making other new/unique content, is to select some choice collections with KW/topic opportunities in organic and add unique content to those pages. At the same time, noindexing the other 90% of excess collections pages.
The thing is there's evidently no method that I could find of just uploading a list of urls to Shopify to tag noindex. And, it's too time consuming to do this one url at a time, so I wrote a little script to add a noindex tag (not nofollow) to pages that share various identical title tags, since many of them do. This saves some time, but I have to be careful to not inadvertently noindex a page I want to keep.
Here are my questions:
-
Is this what you would do? To me it seems a little crazy that I have to do this by title tag, although faster than one at a time.
-
Would you follow it up with a deindex request (one url at a time) with Google or just let Google figure it out over time?
-
Are there any potential negative side effects from noindexing 90% of what Google is already aware of?
-
Any additional ideas?
Thanks! Best... Mike
