Redirect Checker
I follow every redirect to see where it really ends. Paste any address on your site.

What Google wants from a redirect
One step, marked as permanent (301 or 308), straight to a page that works. Each extra step slows Google down, and Google stops after 10 in a row. A redirect marked "for now" (302 or 307) tells Google to keep the old address in search.
Your site can be reached as http or https, with or without www. All of them should end at the same address, or Google may treat them as copies of each other.
