Post Affiliate Pro Links Not Working? Diagnose and Fix Them
When Post Affiliate Pro links stop working, the cause is almost always one of three things: banner or campaign deleted; merchant retires the software; site restructure drops parameters. Click the link in an incognito window and note where you land — a network error page, the wrong page, or a browser error each point to a different fix below.
How a working Post Affiliate Pro link behaves
A healthy Post Affiliate Pro link (the merchant’s own domain) resolves through the tracking hop to your intended destination page. Anything else — an error page, a homepage, a browser error — is one of the failure modes below.
Reference anatomy: https://merchant.com/?a_aid=youraffid&a_bid=11112222
Cause 1: Banner or campaign deleted
The a_bid no longer exists; depending on configuration the link errors or falls back without attribution.
Cause 2: 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.
Cause 3: Site restructure drops parameters
New redirect rules strip query strings before the tracking script runs.
The error signals to look for
These are the exact failure fingerprints Afterlink’s validator checks on every Post Affiliate Pro link:
- ▸a_aid / a_bid stripped in the redirect chain
- ▸click.php-style endpoints returning errors
- ▸Landing page 404
The fix, in order
- ▸Test the link in incognito and note the final URL.
- ▸If you hit a network error page: log into Post Affiliate Pro and check the program status. Closed program = regenerate on the merchant’s current network or replace the merchant.
- ▸If you land on the wrong page (homepage, 404): regenerate the deep link against the product’s current URL.
- ▸If the link doesn’t resolve at all: re-copy it from your dashboard — links get mangled by CMSes, shorteners, and manual edits.
- ▸Fix the link everywhere you published it — then put the whole inventory under automated monitoring so the next failure emails you instead of hiding for months.
Frequently asked questions
Why do my Post Affiliate Pro links break without warning?
Because none of the parties involved notify you: merchants change catalogs and network relationships freely, and Post Affiliate Pro doesn’t audit your published content. The failure is only visible from the outside — by actually following the link.
How do I check all my Post Affiliate Pro links at once?
Afterlink scans your YouTube channel or website, finds every Post Affiliate Pro link (it knows all the tracking domains: the merchant’s own domain), and validates each one end-to-end in minutes.
