As title say,
Can we use Open Redirect as back link?
ex:
http://www.google.com/search?btnI&q=allinurl:mysite_url
which give a page that have link to mysite_url
or sites that auto redirect
https://www.xxxxx.com/go.php?url=mysite_url

Can this links be indexed by google?
This sites will be back link to my site or i just give them value and free back link to them by me trying index the link?
because i tried to index such links with no luck....

Relying on open redirects for backlinks won't benefit your SEO. Google often doesn't index them, and they don't add any significant value to your site. Focus on high-quality backlinks from reputable sites that directly link to your content, which will provide better results for your SEO efforts.

Redirects are considered manipulative and spammy tactics from Google's perspective. Avoiding these methods and focusing on acquiring links from relevant websites through guest posts or PBNs is better.

Thanks for answers, you saved a lot of my time trying to index such redirect links...
I will focus on high quality back links instead, thanks a gain
