Quick answer: The most expensive affiliate marketing mistakes are choosing a deal by its headline number, not reading the terms, running without tracking, relying on one traffic source, sending traffic from countries an offer doesn't accept, bidding on brand names, publishing thin pages, ignoring advertising rules, and never building an audience you own.
I'm Rihards, founder of Seven Affiliates, and I've spent five years in iGaming. Every mistake on this list is avoidable, which is exactly what makes them so annoying.
You know the cartoon where someone steps on a rake and the handle swings up? [Steps forward confidently. Handle arrives on schedule.] These are the nine rakes. They're all lying in plain sight, and people find them anyway.
The 9 affiliate marketing mistakes at a glance
| # | Mistake | What it costs |
|---|---|---|
| 1 | Choosing a deal by the headline number | A big percentage of a small amount |
| 2 | Not reading the terms | Surprises about fees, changes and exits |
| 3 | No tracking of your own | You can't tell what works or check what you're paid |
| 4 | One traffic source | One rule change away from zero |
| 5 | Traffic from the wrong countries | Clicks that can never convert |
| 6 | Bidding on brand names | Withheld commission or a closed account |
| 7 | Thin pages that only push the click | Rejected ads and weak rankings |
| 8 | Ignoring advertising rules | Banned accounts, sometimes regulators |
| 9 | No audience you own | Starting from nothing every month |
The list and the order are my view from five years in iGaming, not a ranked study. Where a published source backs a point, it's quoted and linked below.
Mistakes 1 to 3: how do affiliates lose money before they start?
By agreeing to things they haven't measured or read. None of these three needs any traffic to go wrong. They go wrong at the sign-up form.
Mistake 1, choosing a deal by the headline number: A revenue share percentage means nothing until you know what it's a percentage of. Costs come off first, and whether losses carry into next month changes everything. Our CPA vs RevShare guide has the worked comparison.
Mistake 2, not reading the terms: Real clauses say things like "We reserve the right to change any part of this Agreement at any time", which is from Betfair's published affiliate terms, a large and legitimate program. That's normal. Not knowing it's there is the mistake.
Mistake 3, no tracking of your own: ClickBank's version is blunt: "If you don't know your numbers, you don't really have a business" (ClickBank). Without your own data you can't find your best page or query a payment.
| Mistake | The fix | Read next |
|---|---|---|
| 1. Headline number | Ask what the percentage is calculated on | CPL vs CPA |
| 2. Unread terms | Find the fee, change, activity and exit clauses | 9 red flags |
| 3. No tracking | Set up a tracker and sub IDs before you send traffic | Link tracking |
That's three rakes and we haven't left the garden shed. [Rubs forehead.] Onwards.
Mistakes 4 to 6: what goes wrong with traffic?
People send the wrong visitors, from the wrong places, in ways the offer doesn't allow. Each one feels like progress while it's happening, because the click counter is going up.
Mistake 4, one traffic source: ClickBank puts "Relying on a Single Traffic Source" first on its own list. The next section shows why with a number.
Mistake 5, traffic from the wrong countries: Gambling offers accept players from specific countries. A visitor from anywhere else can click all day and never become a player. Our Tier 1 countries guide covers how offers divide the map.
Mistake 6, bidding on brand names: Buying ads on an operator's own name catches people who were already on their way there. Many programs restrict it, and our brand bidding guide explains why.
| Mistake | How it feels | What's really happening |
|---|---|---|
| 4. One source | "I've found what works" | Someone else controls your whole income |
| 5. Wrong countries | "Look at all these clicks" | None of them can register |
| 6. Brand bidding | "These convert brilliantly" | You're charging the brand for its own customers |
Why is relying on one traffic source so risky?
Because the source can change without asking you. Search is the clearest case. Pew Research Center tracked real Google use and found: "Users who encountered an AI summary clicked on a traditional search result link in 8% of all visits. Those who did not encounter an AI summary clicked on a search result nearly twice as often (15% of visits)" (Pew Research Center, July 2025).
The same applies to an ad account or a social profile: one policy update and the tap is off. Our guide to the best traffic sources covers how to pair a second source that fails in a different way.
Mistakes 7 to 9: what goes wrong with content and rules?
Pages get built for the click and not the reader, rules get skimmed, and nothing is kept for next month. These are slower rakes. The handle takes a while to arrive, but it arrives.
Mistake 7, thin pages that only push the click: Google Ads rejects "Destinations that are solely designed to send users elsewhere" (Google Ads). Google Search asks: "Does the content provide original information, reporting, research, or analysis?" (Google Search Central).
Mistake 8, ignoring advertising rules: ClickBank lists "Ignoring Compliance and Ad Policies" as a top mistake. On disclosure, the US Federal Trade Commission says to place it "so it's hard to miss", and warns that disclosures are "likely to be missed if they appear only on an ABOUT ME or profile page" (FTC).
Mistake 9, no audience you own: "Not Growing an Email List" is on ClickBank's list too. A ranking or an ad account can be taken away. A list of people who asked to hear from you can't.
| Mistake | The fix | Read next |
|---|---|---|
| 7. Thin pages | Give the reader something before the link | Landing pages |
| 8. Ignored rules | Read the platform's gambling policy and your country's ad rules first | Compliance rules |
| 9. No owned audience | Start an email list or community with proper consent | Email marketing |
Gambling adds weight to number 8. The rules on age, bonuses and self-excluded players are stricter than in most niches, and "I didn't know" has never once worked as an appeal.
Which mistake should you fix first?
The one nearest the money. Tracking comes first because without it you can't see any of the others. Then terms, then the traffic checks, then the slower content work.
Our metrics guide covers which numbers to watch once the tracking is in.
How we help you avoid them at Seven Affiliates
Most of this list comes down to asking before sending. We're building a curated network of private iGaming offers, and each offer's terms are agreed with your account manager, so the questions have somewhere to go.
| Mistake | What we publish, or what to ask |
|---|---|
| Headline number | RevShare is on NGR, 35% by default, with no negative carryover |
| Deal type | CPA, RevShare and Hybrid are available |
| Brand bidding | Not allowed by default, unless the specific offer explicitly allows it |
| Countries and traffic sources | Depend on the offer: ask before you send traffic |
| Tracking | Our dashboard tracks your traffic in real time |
Ask your account manager the awkward questions early, in writing. It's a lot cheaper than finding the rake with your face.
FAQ
What are the most common affiliate marketing mistakes?
Relying on one traffic source, not tracking results, not reading program terms, choosing a deal by its headline rate, ignoring advertising rules, and publishing thin pages that offer nothing beyond an affiliate link.
What is the biggest mistake new affiliates make?
Running without tracking. Without your own data you cannot tell which pages or traffic sources earn money, and you cannot check whether you were paid correctly.
Why do affiliates fail?
Common reasons are depending on a single platform that changes its rules, sending traffic an offer cannot accept, breaking program or advertising rules, and scaling before the numbers show a campaign is profitable.
Do affiliates need to disclose affiliate links?
In the United States, the FTC says endorsers should make a financial relationship with a brand obvious and place the disclosure where it is hard to miss. Other countries have their own advertising rules.
Is brand bidding a mistake for affiliates?
It is when the program forbids it, which many do. Bidding on an operator's brand name without permission can lead to withheld commission or account closure.
