Agreements and terms

Channel restrictions

Also called traffic source restrictions, allowed channels, permitted traffic sources, promotional method restrictions.

Short answer

Channel restrictions are affiliate program terms setting out which traffic channels affiliates may use – and which are forbidden, such as advertising on the store’s brand name, email campaigns or incentivised traffic. They sit in the program terms and apply from sign-up.

Definition of Channel restrictions.

A channel restriction limits where the affiliate’s traffic may come from. The store can allow content sites, SEO and social media but forbid paid search advertising on its own brand terms, email, cashback, coupon sites or browser extensions. The purpose is to protect margins and brand: traffic from the wrong channels can make the store’s own advertising more expensive, dilute the customer experience or move commission to clicks with no real value.

The most common restrictions each have their own rationale. Bans on brand bidding exist because affiliates bidding on the store’s name in Google Ads compete with the store’s own ads and push the cost per click up. Bans on incentivised traffic exist because users rewarded for clicking rarely become customers. Bans on browser extensions and adware exist because they can insert themselves into the store’s own checkout flow and take credit for sales that would have happened anyway.

A channel restriction is a contractual term, not a technical block. No tracking system can know for certain which channel a click came from – referrer information can be missing or manipulated. Enforcement therefore happens through follow-up: the store monitors searches for its own brand, reads patterns in clicks and conversions, and responds by rejecting sales, ending the partnership or blocking the affiliate when the term is broken.

How a store writes a channel restriction that works

Be specific. No paid advertising on our brand name, its misspellings or brand name plus discount code is unambiguous; no spam is not. Name the channels – paid search, email, cashback, incentivised traffic, browser extensions – and state the consequence of a breach, so both parties know the rules before the first click.

Follow up yourself. Search regularly for your own brand name and the closest misspellings in a clean browser, and see which ads appear above the organic results. Compare new affiliates’ click patterns with the channels they have declared. A term without follow-up changes no behaviour.

How it goes wrong

  • 01

    The term is worded too vaguely

    Wording such as only relevant traffic creates conflicts when a sale is rejected. Name the forbidden channels and describe what happens in case of a breach – then a rejection can be defended and a complaint can be settled.

  • 02

    The affiliate builds before reading the terms

    Weeks invested in a PPC setup or a mailing list are wasted if the channel turns out to be forbidden in the program. Read the channel restrictions before choosing a channel – not after the first rejected sale.

  • 03

    Terms without follow-up

    A channel restriction does not in itself stop any traffic. Stores that never search for their own brand or read click patterns only discover breaches when click prices rise or customers complain.

Channel restrictions in practice

In Affilyflow, channel restrictions are part of the program terms, which the affiliate accepts on sign-up. We do not claim to be able to enforce them automatically – no system can determine with certainty which channel a click came from. Enforcement lies in the approval flow instead: the store has the program’s approval period (30–90 days) to reject a sale, a rejection requires a reason the affiliate can read, and a blocked affiliate cannot earn, no matter which route the sale comes in by.

Frequently asked questions

Can an affiliate bid on a store’s brand name in Google Ads?

Only if the program terms allow it. Bans on brand bidding are among the most common channel restrictions, because affiliates bidding on the store’s name make the store’s own advertising more expensive. Read the channel restrictions in the program terms before setting up the campaign. If the answer is not clear-cut, ask the store in writing.

What happens if an affiliate breaks a channel restriction?

The consequence is set out in the program terms and ranges from rejection of the affected sales to ending the partnership and blocking. In Affilyflow, a rejection requires a reason the affiliate can read, and a blocked affiliate cannot earn commission, no matter which route the sale comes in by.

Which channels are most often restricted in affiliate programs?

Paid search advertising on brand terms, email campaigns, incentivised traffic, cashback and coupon sites, and browser extensions. The restrictions vary from program to program – the same channel can be forbidden in one place and welcome in another.

How does a store detect breaches of channel restrictions?

By searching for its own brand name and misspellings and seeing which ads show up, by reading referrer and click patterns in the tracking data, and by comparing an affiliate’s declared channels with the actual conversion patterns. Sudden click spikes without matching content are a classic signal.
