What makes a backlink valuable
Not every link is equal. The most valuable links come from relevant, trusted sites with real traffic, in the body of a page people read, without nofollow. A link in a footer of an unrelated site with no traffic is worth close to nothing, however high its authority score.
The price range is a rough guide from common market rates for sponsored placements. Buying links to manipulate rankings is against Google's guidelines; the calculator is equally useful for judging directories, guest posts and partnerships.
Questions
Is a nofollow link worthless?
No. It can bring visitors and brand searches, and Google treats nofollow as a hint. It is worth less for rankings.
What about launch directory links?
Directories with real traffic and a dofollow link, like some launch platforms, can be good early links. Check each with the nofollow checker.
Should I buy backlinks?
Paid links meant to pass ranking value break Google's spam policies. Spend on things that earn links: tools, data, great content.
How accurate is the price?
It is a ballpark. Prices vary widely by niche and negotiation.
