An affiliate link can return HTTP 200 and still send visitors to the wrong place. It can also hide a Sub ID without losing the data in the network’s reporting system. The right diagnosis starts with the publisher’s published link, then separates network routing, advertiser settings, conversion attribution and payout evidence.
Copy the exact live URL and publisher ID.
Inspect hops and Sub-ID survival where testing is permitted.
Correct product, homepage fallback or unavailable item?
Use authenticated provider reports; URL parameters are not proof.
Pending, approved, reversed and cleared are different.
Verify withdrawal against independent bank evidence.
Country, device, consent and promotion-method approval are separate context checks. If no official evidence exists, record UNKNOWN.
First distinguish the symptom
“The link redirects to the homepage” describes a destination outcome, not its cause. A homepage can be configured as an intentional fallback, a product may have moved, the advertiser may restrict deep-link domains, or the wrong URL may have been published. None of those observations alone establishes whether a commission was attributed.
1. Compare the intended URL with the URL actually published
Inspect the rendered HTML of your own page and copy the exact outbound href. Compare it with the approved network-generated link saved in your placement record. Check the network tracking domain, publisher identifier, campaign/creative reference, deeplink destination and any required Sub ID or click-reference fields. Record the page URL, publication revision, timestamp and, where possible, an SHA-256 digest of the HTML used for your check.
A link replaced by a page builder, link cloaker, redirect plugin or content optimizer can differ from the one you originally created. Do not assume a valid-looking button proves the final URL is correct. If the page uses JavaScript to generate the link, a static HTML read alone is insufficient: label the published value UNKNOWN until a separately authorized browser observation is available.
2. Keep four approval layers separate
An approved publisher account is not the same as approval of your website, email list or social channel. Likewise, a network account does not automatically establish an approved merchant/program relationship, and that relationship does not prove that paid search, coupon, email, cashback or another promotion method is permitted. Verify each layer from the correct account and program documentation.
If a program’s policy or your property-specific approval cannot be verified, record it as UNKNOWN rather than “allowed” or “prohibited.” A forum report about a rejection can be useful for discovering questions to ask, but it is not the advertiser’s binding rule.
3. Check whether the network documents a fallback
Awin Classic: Awin documents a deeplink-domain verification feature. When an advertiser activates accepted-domain restrictions, deeplinks to other domains can go to the program’s default landing page. Awin also documents a fallback for malicious-flagged deeplinks. This is conditional Awin Classic configuration behavior, not proof that every Awin advertiser enforces the same settings. See Awin: Deeplink domain verification.
impact.com: An advertiser’s Gateway configuration can use a default landing page when a custom ad landing page does not work. Separate permitted-domain rules may instead send traffic to a generic impact.com page. Those are different destination outcomes and should not be combined into one “homepage redirect” rule. See impact.com: Gateway tracking settings.
Record the actual final destination and the expected product/category URL separately. A generic network warning page, advertiser homepage and correct product URL are three different classes.
4. A missing visible Sub ID does not always mean lost attribution
Check the publisher ID and tracking parameters at the network boundary where a capture is documented, not merely on the merchant’s final product page. Some network tools deliberately shorten or transform the URL. For example, impact.com explains that Sub IDs and Shared IDs from an original tracking link can remain in reports even though they are not visible in the vanity URL itself.
The appropriate classification for an unverified vanity link is provider readback required. Examine the correct publisher-account reporting, the relevant program/campaign and matching time window. The absence of a readable Sub ID in a short URL is not proof of commission loss, and the network documentation is not proof that your particular link was configured correctly.
5. Keep consent, geography and device in context
Two observations may differ because the visitor’s consent signal, market, device, app-install status or browser changed. Awin’s partner consent framework documents that when a visitor is indicated as not consenting, Awin does not set the tracking cookie or transfer a click identifier to the advertiser landing page for that journey. That needs to be considered in an attribution diagnosis, without drawing legal or account-specific conclusions from the documentation alone.
When repeating an authorized test, use the same country, device profile, account, program, campaign, source placement and consent context. Record HTTP status, redirect hops, redirects to a wrong product or homepage, and any transient block or out-of-stock status. Avoid firing uncontrolled affiliate clicks or using customer-identifying tokens.
Continue diagnosing your affiliate results
If your link reaches the intended product but sales remain missing, use our no affiliate sales diagnostic.

6. Verify attribution and payment separately
A functioning URL is only the first step. A tracked click is not an approved conversion; a reported sale may later be adjusted or reversed; an approved commission is not a bank receipt. For a commercial confirmation, reconcile a specific transaction with authenticated provider reporting using the correct publisher account and program. Preserve the source, identifier, timestamps, currency, adjustment history and verification status. Then independently verify payout records and settlement—not merely a dashboard balance.
| Observation | What it supports | Next step |
|---|---|---|
| HTTP 200, wrong product or homepage | Destination drift to investigate | Compare permitted domains, program fallback configuration and exact deeplink. |
| Sub ID absent from an impact.com vanity URL | Visibility unknown, not proven tracking loss | Check authenticated partner reporting and original link configuration. |
| HTTP 429 or 503 | Transient/rate-limited or blocked response | Recheck with bounded, authorized requests; do not declare a permanent failure. |
| Click in network dashboard, no confirmed sale | Possible recorded click, not a payout | Reconcile transaction, advertiser validation and finance status separately. |
| Program page accessible, approval undocumented | Policy/relationship status UNKNOWN | Inspect the correct publisher account, property and program terms. |
When should you label a link “broken”?
Use a confirmed technical failure such as a persistent invalid endpoint or independently corroborated wrong destination. For suspected attribution loss, require stronger causal evidence: multiple independent same-context observations and, where possible, an authenticated provider-level transaction or tracking report. Never promote a single forum report or transient browser event into a permanent merchant rule.
