Squarespace to Webflow: redirecting date-based blog urls and everything else

/about · /services/web-design — pages, at the root or one folder deep. No trailing slash. These usually survive a rebuild with the same slug.

/blog/2021/3/14/post-name — the default blog url with year, month and day. Month and day have no leading zero. A blog that switched to the short format later has both patterns live.

/blog/post-name — the short blog url format. Same shape as a Webflow collection item.

/blog?category=Name · /blog?tag=Name · /blog?offset=… — category and tag filters and pagination, as query strings on the blog page. The category names keep their capitals and spaces.

/shop/p/product-name · /events/event-name · /gallery/… — commerce, events and gallery collections. Each has its own folder, named after the collection.

/s/file-name.pdf — files uploaded through the link editor. Short, unguessable, and linked from newsletters and other sites.

/blog-1 · /home-1 · /new-page — the slugs Squarespace assigns when a page is duplicated or created without a title. They look like test pages and are often live.

• The sitemap. /sitemap.xml is generated by Squarespace and lists every enabled page and post not hidden from search engines. Silentfrog reads it automatically when the run starts.
• Search Console. Disabled pages are not in the sitemap but may still be linked and receive traffic. The pages export catches them, and Silentfrog lists the urls the crawl did not find so they can be added as rows (traffic data).
• Url mappings. Settings, advanced, url mappings. One line per redirect in the form /old -> /new 301. Copy the whole box before the site closes; there is no export button.

posts lose the date — a Webflow collection item is /blog/slug, or whatever folder the collection has. There is no way to keep the year and month in the path, and no reason to.

filters become pages or nothing — a Webflow category is a collection of its own with real pages, /category/name, or it does not exist. The query-string filters have no equivalent either way.

the shop folder changes — Webflow Ecommerce puts products at /product/slug and categories at /category/slug. Squarespace’s /shop/p/slug has the same slug one level deeper.

files get new urls — uploaded files live on Webflow’s asset domain. The /s/ urls can be redirected there one by one.

date-based posts — per row, on the slug. A wildcard rule cannot drop the three date segments, because Webflow’s capture group puts back exactly what it captured. The matcher scores the last path segment and the title, which is why these come out as high-confidence matches without any manual work (how matching works).

short-format posts — exact matches if the collection folder is still /blog; a directory rule with keep sub-paths if it changed, exported as one wildcard row.

filters and pagination — nothing to do. A redirect rule matches the path, so /blog?category=Design follows whatever /blog does. If you built a categories collection on Webflow and a Squarespace category ranked, add one manual row per category.

shop, events, gallery — /shop/p/(.*) to /product/%1 is one wildcard row if the slugs were kept. Events that have passed are a 410, not a redirect. A gallery page with no successor goes to the closest page that exists.

the -1 pages — /home-1, /blog-1 and friends. Check whether each is a live duplicate or a leftover. A duplicate redirects to the page it copied; a leftover is a 410.

The mappings box is where every earlier rename ended up, and the sources in it are urls that still get requests, or nobody would have written the rule. Each one needs a row in the new file, but not the row that is there now. /old -> /middle followed by your new /middle,/final is a chain. Paste the left-hand sides into the url list when starting the run and let them resolve against the new site; the target the tool finds is the final one, and the row comes out as /old,/final.

Squarespace file links are short paths like /s/pricing-2024.pdf. They are not in the sitemap and a crawler only finds the ones still linked, so the Search Console export and the backlink report are the sources. Each one worth keeping gets a manual row pointing at the file’s new asset url. Webflow accepts an absolute url as a redirect target, so the row can point straight at the asset domain.

• Copy the url mappings box and export the Search Console pages report while the site is still up.
• Start a run with the Squarespace domain and the Webflow staging domain; paste the mapping sources and the Search Console urls into the url list (starting a run).
• Add a directory rule for the shop folder and for any collection whose folder changed, with export as wildcard rule ticked.
• Sort by confidence, review the date-format posts that did not match exactly, and verify what you accept.
• Download the Webflow csv and import it before the domain moves (importing into Webflow).
• Point the domain at Webflow, publish, and crawl the old url list against the live site: one 301 and then 200 for every row.

• Pages keep their slugs and need no row; the work is the blog.
• Date-based post urls cannot be handled by a wildcard, so they are matched per post on the slug, and nearly all of them come out at full confidence.
• Category and tag filters are query strings and follow whatever /blog does.
• The shop folder is one wildcard row from /shop/p/(.*) to /product/%1.
• Copy the url mappings box before the site closes and resolve its sources against the new site directly.
