Link from the competitor site?

I found that the competitor site has a broken link I can register but theres no other backlinks for this domain. It seems to be an old product that isnt around. Would a link like this be good for registering? Or should PBN links have more backlinks?

Check the PA before you buy a redirect 301 domain for 1 backlink.. I wouldn't do it I think its safer and better to invest in high quality backlinks (like PBN)

It all depends on authority of a page linking to that abandoned website.

1. If it's a homepage link of a website that ranks in top 3 - it's definitely worth it.

2. If it's an internal page of a website that ranks in top 3 that is crawled by Google once in a year ... I would still get it! ( if it costs about 50 bucks.)

3. If it's more expensive domain or if your competitor isn't ranking to well - there's no practicability in buying that domain.

Good luck!
