// alternatives — backlink exchange platform
The best Authority Exchange alternative, free
A credit-based link exchange marketplace with a paid tier.
What is Authority Exchange?
Authority Exchange is a link exchange marketplace connecting brands, publishers, and link builders through a credit system rather than direct payment per link. Each link is assigned a credit value based on the site's Ahrefs DR, and members must verify their ability to build links on their domain before joining. Links must stay live for at least six months. Building links themselves is free once you're in, but access to the platform runs on a monthly subscription fee.
Authority Exchange vs Exchange Backlinks
| Authority Exchange | Exchange Backlinks | |
|---|---|---|
| Core model | Credit-based exchange marketplace | Free reciprocal exchange |
| Price | Monthly subscription fee (links themselves are free) | Free, no subscription |
| Vetting | Verified brands and publishers only | Any B2B site in a supported niche |
| Link duration requirement | Minimum 6 months, enforced | Agreed directly between members |
| Niche matching | General, cross-industry | B2B niches only |
Where Authority Exchange still wins
The verification bar and enforced 6-month minimum mean links on Authority Exchange tend to be more consistently high-quality across a broad set of industries — useful if you're not exclusively B2B and want a vetted pool of publishers rather than a niche-specific match.
Why teams switch to Exchange Backlinks
Authority Exchange still charges a subscription just to access the credit marketplace, on top of the DR verification requirement. Submit your site to Exchange Backlinks and there's no subscription at all — you get matched weekly with a real site in your niche and agree on the swap yourselves, with no vetting fee standing between you and your first exchange. If a credit-based structure still appeals to you, KarmaLinks and RankChase run comparable systems.

Do I need a minimum Domain Rating to join Authority Exchange?
The platform doesn't publish a fixed DR floor, but every member must verify their ability to build links on their own domain, which filters out newer or unverified sites in practice.
