Dub Marketplace gives creators, publishers, and agencies one place to find and manage partner programs.
That is convenient.
Instead of creating separate relationships everywhere, you can discover programs, track results, and manage more of the affiliate process centrally.
The biggest danger has nothing to do with Dub.
The danger is seeing dozens of commission opportunities and deciding that every product is suddenly amazing.
That is how review sites lose credibility. A commission should never be the reason you praise something you would not otherwise recommend.
Pros
Centralized partner programs. Easier tracking. Convenient way to manage multiple relationships.
Cons
Convenience can tempt publishers to promote products that are a poor fit for their audience.
My take
Good platform. Be selective. Reader trust is worth far more than one commission.
