Is it possible to use a backslash in a URL on Webflow? If not, should I do 301 redirects from URLs with backslashes to URLs without backslashes if the marketing agency already did redirects?

Webflow does not support backslashes in URLs, as they are not valid in URL paths according to standard URL syntax. You cannot create or route to Webflow pages using backslashes ( \ ) in the path.

1. Why Backslashes Don’t Work in URLs

• Backslashes are not valid path delimiters in web URLs. Web standards require forward slashes ( / ) instead.
• Web hosting platforms like Webflow automatically reject or sanitize URLs with backslashes to prevent errors or security issues.
• Browsers may misinterpret backslashes, potentially converting them to forward slashes, but this behavior is inconsistent and should not be relied upon.

2. What to Do About Existing Backslash URLs

• If a marketing agency already implemented redirects from URLs containing backslashes, they likely redirected them to valid forward-slash ( / ) equivalents.
• These redirects cannot be managed from within Webflow, because Webflow’s built-in 301 redirect tool only accepts valid forward-slash paths.
• If these redirects were done at the domain level (via Cloudflare, your DNS provider, or an external redirect server), they should remain in place outside of Webflow.

3. Recommended Redirect Strategy

• Confirm that any external redirects from backslash URLs (e.g., example.com\page) to valid equivalents (e.g., example.com/page) are working correctly via 301.
• If these redirects are handled by the agency externally, do not try to recreate them in Webflow, as Webflow cannot process URLs with backslashes.
• Make sure all internal linking, email campaigns, and ads use forward slashes to avoid broken links in the future.

Summary

Webflow does not support backslashes in URLs. If any redirects from backslash URLs exist, they must remain managed externally via hosting or DNS tools. Ensure all your URLs use forward slashes going forward.
