Shopify handle vs product title
The title can say “Organic Cotton Crew Socks — 3 Pack, Black”. The handle from this slug generator can be organic-cotton-crew-socks-black. Shopify will not mind. People pasting the product URL will prefer the short one. Leave filler words off unless they are the brand. Color at the end helps when each color is its own product. If color is a variant, do not stuff every color into the handle.
Changing a Shopify URL later
Edit a live handle and the old /products/old-handle dies. Ads and influencer links keep pointing at a 404. In admin: Online Store → Navigation → URL Redirects. Same screen for collections, pages, and blog posts. If two products want the same handle, Shopify appends a number. Treat that as a warning.
CSV imports
A supplier CSV is not a URL strategy. For a list of titles, use the bulk slug generator, paste the title column, copy the slug column, and map it to Handle. Rewrite garbage titles first. “SOCK CREW ORG CTN 3PK BLK M” will slug honestly, which is not the same as well.
