ReferralAuthority + LinkCheck.app
Buying links without a monitoring layer creates a blind spot after the transaction, which is exactly when many expensive problems begin. ReferralAuthority requires LinkCheck.app first because serious authority building continues through monitoring, verification, and recovery.
A buyer can vet a vendor, review standards, and still lose visibility once a placement goes live. Pages change. Links disappear. Sites decline. Context shifts. If nobody is watching what happens next, the asset can quietly lose value while the spend still sits in your reporting as if nothing changed.
You cannot quickly tell which links are still live. Client reporting gets weaker. Recovery work happens late because nobody sees drops early. Vendor accountability gets harder when the team has no ongoing monitoring baseline.
The requirement is not arbitrary friction. It is a buyer-protection rule. LinkCheck.app gives teams a working monitoring layer before they enter the marketplace, so buying happens with post-delivery accountability.
Once your account is set up and the baseline is in place, you can request marketplace access. From there, buying and monitoring live inside the same operating model.
ReferralAuthority is not asking buyers to replace every SEO platform they use. The requirement exists because marketplace access depends on a consistent monitoring workflow that supports live-link accountability after purchase.
