SEO problem: Filter in collection pages creates it's own URL - how to fix this?

Technical Q&A

Topic summary

Issue: An ecommerce store’s collection filters generate parameterized URLs (e.g., …/collections/wines?filter.p.m.custom.grape_variety=Albarino&…) and product links clicked from filtered results append extra parameters (e.g., ?_pos=2&_fid=…&_ss=c). The store owner worries these URLs aren’t SEO-friendly.

Details: Examples include filtering by grape variety and country via query parameters (key=value after “?” and joined with “&”). Product pages also gain tracking/position parameters when accessed from filtered lists.

Response: A contributor states this behavior is standard across ecommerce platforms. Parameters are required to express filter criteria and identify which results to show. They assert these URLs are user-generated, not permanent, and won’t impact SEO or be indexed, so there’s no need to worry.

Outcome/Status: No technical changes or fixes were recommended; the guidance is to leave the behavior as-is. No evidence or additional steps (e.g., confirming indexing behavior) were provided. The discussion currently rests on reassurance rather than a verified technical resolution.

Hello,

I need some help regarding my filters and the way it sorts things out. My shop creates a new URL for every filter and this causes a huge mess in terms of URL

I sell wines and for example:

Moreover, once I click on any of these products after filtering or searching on the search bar, it comes up with some random numbers at the back.

For example, this is the product

And this is the product after I click on it using the filters

I read online saying that these sort of URL are not SEO friendly and I do need some help or suggestions on this.

Thank you.

@rt12820 There is no mess in your URL or with your store! Every ecommerce platform works like this if you opened a product listing page and if you add some filters, variants or other attributes then how to identify and show your filtered results without passing parameters ? so by adding parameters in the back of the URL tell the path which products want to show with the filter criteria.

Second thing, it is created by user for showing filter result it is not impacting in SEO or Search Engine and it won’t indexed in search engine because it is not permanent URL it is created automatically when someone trigger or play with filter so no need to worry!
