White-label affiliate software
Post Affiliate Pro Affiliate Link Checker
Post Affiliate Pro runs the in-house programs of thousands of small and mid-size merchants, with a_aid (affiliate) and a_bid (banner) parameters on the merchant’s own domain. Links fail when the merchant retires banners, restructures their site, or drops the software — with no network to notice on your behalf.
How Post Affiliate Pro links work
Typical link
https://merchant.com/?a_aid=youraffid&a_bid=11112222Post Affiliate Pro tracks via parameters (a_aid, a_bid) on the merchant’s domain, read by the software’s script or a redirect script (often scripts/click.php) that sets the affiliate cookie.
Attribution depends on the merchant keeping the software installed and the specific banner (a_bid) alive. Both are invisible from the outside except through behavior: dead banners redirect oddly or drop parameters.

How Post Affiliate Pro links break
Banner or campaign deleted
The a_bid no longer exists; depending on configuration the link errors or falls back without attribution.
Merchant retires the software
Pages load normally; a_aid does nothing. Detectable only via test conversions or your affiliate dashboard on the merchant’s program.
Site restructure drops parameters
New redirect rules strip query strings before the tracking script runs.

How Afterlink checks Post Affiliate Pro links
Afterlink extracts every link from your YouTube channel or website, recognizes Post Affiliate Pro links by domain and parameter signature, then runs five checks on each one: the full redirect chain (including JavaScript and meta-refresh redirects), network error-page detection, destination verification against the embedded target, tracking parameter analysis, and deep-link decay detection (product page silently replaced by a homepage). Every link gets a clear verdict — working, warning, or broken — with the evidence attached.
Frequently asked questions
Why do small-merchant affiliate links break more often?
Small merchants restructure sites, switch platforms, and abandon affiliate software far more often than enterprise brands — and nobody notifies affiliates. In-house program links deserve more frequent checks than big-network links, not fewer.
Can Afterlink detect Post Affiliate Pro links?
Yes — by their a_aid/a_bid parameter signature on any domain, the same technique used for TUNE and other white-label platforms.
