Impact.com Broken Link Checker (Free Tool)

Short answer: Impact affiliate links break in ways generic checkers miss — brand-owned tracking subdomains, SSL expiry, deactivated campaigns. PRG's free Impact checker catches all three in a single scan.

Why Impact.com links are hard to monitor

Many large retail and consumer brands run their programs on Impact. Most use one of two patterns:

impact.com / go.impact.com — Impact's own redirect domain.
Brand-owned subdomains like partner.brand.com — each brand controls its own SSL and DNS, so failures are independent.

(Note: prf.hn is sometimes mistaken for an Impact domain — it actually belongs to Partnerize, a different network. PRG handles both correctly.)

A monitoring tool that only checks impact.com itself will miss every brand-domain failure. That's why dedicated Impact link monitoring is necessary.

The 5 most common Impact link failures

Brand campaign deactivated — the link still redirects, but the brand has paused the program. No commission paid.
Brand subdomain SSL expired — browsers show a security warning, drop-off spikes.
Tracking subdomain DNS removed — when the brand stops working with Impact, the subdomain often disappears.
Click ID parameter dropped — long redirect chains can strip the irgwc or clickid param.
Landing page replaced — the destination URL now redirects to homepage, killing the deep link's intent.

How to use the free Impact link checker

Go to the homepage and paste any URL on your site that contains Impact affiliate links.
PRG will surface every Impact and brand-owned tracking link on that page.
Each link is checked: redirect chain, final URL, click ID survival, destination availability.
You'll see exactly which brands have broken integrations, ranked by estimated revenue impact.

What to do when an Impact link is broken

Confirm the campaign status inside Impact — paused or active?
Test the link in an incognito window to rule out browser cache.
If the brand subdomain has SSL or DNS issues, contact the brand's affiliate manager directly.
Replace the link in your content with a working alternative or a different program.
Set up ongoing alerts so you know within hours when it happens again.

Frequently asked questions

Is there a free Impact.com broken link checker?

Yes. Partner Revenue Guard offers a free one-page Impact link scan with no signup required. Paste any URL containing Impact.com or brand-owned tracking links and get a health report in seconds.

Why do Impact.com links fail silently?

Impact uses brand-owned tracking subdomains (e.g. partner.brand.com). Each brand domain can fail independently of impact.com, the brand can deactivate the campaign, or the tracking subdomain's SSL certificate can expire. None of these usually return a hard 404.

What is prf.hn?

prf.hn is Partnerize's tracking domain (formerly Performance Horizon) — a separate affiliate network, not Impact. People confuse the two because both power large brand programs. If your link goes through prf.hn, it's a Partnerize link, and PRG monitors it as such.

How does PRG monitor Impact affiliate links?

PRG follows every redirect, validates the campaign ID and click ID parameters survive the chain, checks the destination loads, and detects when a brand has deactivated the campaign by inspecting the final landing page.

Can I monitor multiple Impact brand domains at once?

Yes. Each brand-owned tracking domain (partner.brand.com, etc.) is monitored separately so you know which specific brand is failing — not just "an Impact link broke".
