Backlink Tools — FAQ
How do I estimate what a backlink is worth?
Use the Backlink Value Calculator above. It combines the linking domain's authority (DR/DA), its organic traffic, whether the link is dofollow or nofollow, where it sits on the page, and how relevant the site is to yours. The result is a transparent dollar benchmark you can use to prioritize outreach or sanity-check a sponsored-placement quote — no backlink database required.
Can I check any site's backlinks for free here?
Not exact backlink data — that requires a crawler index like Ahrefs, Semrush, or Moz, which we don't try to replicate. What we do offer free is a domain strength estimate (authority score plus a rough backlink range) for a quick gut-check, plus tools to value a link and find places to earn one. We'd rather be honest about that than pretend to be a backlink index we're not.
What makes a backlink high quality?
Four things stack together: the linking domain's authority, its real organic traffic, whether the link is dofollow or nofollow, and how topically relevant the site is to yours. A relevant, in-content dofollow link from a mid-authority site with real traffic often beats a high-DR link buried in an unrelated footer.
Where can I get backlinks for free?
High-authority platforms like Medium, Reddit, Quora, Tumblr, and Substack let you create a profile or publish content with a link, for free. They're often nofollow, but they still diversify your profile and get new pages crawled faster. See our full list of 20 free high-DR backlink sites for the complete rundown and how to use each one without looking spammy.
