What types of redirects can it detect?

The tool detects 301 (permanent), 302 (temporary), 303, 307, and 308 redirects, as well as meta refresh and JavaScript redirects when possible.

Why is checking redirects important for SEO?

Redirect chains can slow down page load times and dilute link equity. 301 redirects pass link juice, while 302s may not. Long chains (3+ hops) should be avoided for optimal SEO.

Are there CORS limitations?

Due to browser CORS restrictions, some redirects may not be traceable from the browser. For comprehensive results, the tool uses a lightweight proxy API when available.
