Welcome to the Q&A Forum

@mark_seomoz1 If i understand you want to see who is linking to you and if HTTP vs htts? don't forget you can use Search engine console too! Wouldnt a sort in e.g. Google sheets work for this? just sort via HTTP then split via text to collum to get domains and de-dupe and it will roughly show you domains doing that in a few min.

Unless you are chasing some hypostasis as long as your site is https it really isn't much to worry about nor much you can do.

Hi webmaster,

When exporting links from Moz Link Explorer, they come without http part.

You can try using tools like http response header checker.

1. https://httpstatus.io/ - can check 100 URLs at a time. Very fast

2. https://www.bulkseotools.com/bulk-http-header-code-checker.php - 500 at a time. A bit slow

3. Screaming frog - you should know how to use this tool.

PROCESS

You will need Google Sheets for it.

1. Export Linking Domains from MOZ

2. Add "http://" to every domain

3. CONCATENATE strings A and B = Write this formula in C column "=a2&b2"

4. Crawl the http URLs

5. Check which URLS contain 200 status codes, filter out REDIRECTED URLS containing https. Here they are http domain backlinks. This is how I would solve your task.

I hope it helps. If you have questions, you are welcome.
