Influencer Marketing in iGaming: What to Buy from Streamers and How to Measure It

An influencer campaign in iGaming often starts with “how much is a placement with this streamer?” and ends with an argument about what that placement actually delivered. To avoid the argument, build the deal around three things: what you're buying, which platform rules allow it, and how you'll measure the result.

This piece is for brands that buy integrations and for influencer agencies that sell them. We only cover B2B partnerships with licensed operators and 18+ audiences.

What you're buying: four main formats

Each format has its own attention mechanics and its own way of measuring. Mix them into one report without a breakdown, and you won't know what worked.

Rule of thumb: streams and videos sell trust, Telegram sells fast traffic, short-form sells awareness. If the campaign goal is FTDs, start with formats where the link and promo code sit right next to the call to action instead of getting lost at the bottom of the description.

Platform rules: what's changed since 2022

The most expensive mistake is buying an integration that the platform will take down or restrict. Below are the key changes of recent years, but platforms update their wording regularly, so check the current rules before every launch.

Twitch

Twitch announced in September 2022, and from October 18, 2022 enforced, a ban on streaming sites with slots, roulette or dice games unless they're licensed in the US or in other jurisdictions with sufficient player protection. Sports betting, fantasy sports and poker weren't covered by the ban. Links and referral codes for such sites were already prohibited before that, and Twitch later added to its list of specific banned sites.

YouTube

Since March 19, 2025, YouTube has prohibited directing viewers to gambling sites not certified by Google — via a link, a logo, an image or a verbal mention. Online casino content was age-restricted: it isn't shown to viewers under 18 or to signed-out users. Promising guaranteed winnings is prohibited even for a certified site.

In November 2025 the rules were expanded: age restrictions now also cover social casinos and mechanics involving digital items with monetary value. For brands, the takeaway is simple: a YouTube integration only makes sense for a licensed operator that has passed Google certification in the relevant country, and only for an adult audience.

Ad disclosure

Viewers must be able to tell they're watching an ad. YouTube has a paid promotion setting in the video details that adds a disclosure at the start of the video. Since 2023, Twitch has had a Branded Content checkbox in the streamer's dashboard. In 2023, the UK's Advertising Standards Authority (ASA) stated explicitly that it expects a prominent label such as “Ad” at the start of a post, before the viewer starts watching.

Local laws add their own requirements. In the UK, since October 1, 2022, gambling ads must not be of strong appeal to under-18s, so creators with a significant underage audience aren't suitable for them. In Italy, the regulator AGCOM explicitly extended the Decreto Dignità ban on gambling advertising to influencers in 2019. How to check a GEO before launch is covered in our pre-launch compliance checklist.

Payment models: flat fee, CPA, Hybrid, RevShare

The payment model splits the risk between the brand and the creator. The less you know about how an audience converts, the more sense it makes to choose a model where the risk is shared.

• Flat fee. Payment per placement: a stream, a video, a post. All the risk sits with the brand. Works for awareness and for big creators who won't work any other way.
• CPA. Payment per target action, most often a first deposit with minimum conditions. The risk sits with the creator, so strong creators are reluctant to agree to pure CPA.
• Hybrid. A small fixed fee per placement plus CPA. The most common compromise for a first collaboration.
• RevShare. A percentage of the brand's revenue from referred players. Works over the long run, and only with transparent reporting.

In negotiations, it helps to tie the model to the stage of the relationship from the outset:

“For the first placement, we suggest a hybrid: the fixed fee covers your work, and the CPA shows how your audience converts. If the numbers add up, from month two we can discuss RevShare or a higher rate.”

Details and common traps of each model are in our breakdown of CPA vs RevShare vs Hybrid.

How to choose an influencer: four filters

1. An 18+ audience

Ask for screenshots of the age analytics from the platform dashboard for the last 90 days, not a media kit. If there's no age data — and on Telegram you usually can't get it — judge by the content themes, the comments and past integrations. A creator watched by schoolkids is a no, however big the reach.

2. Audience GEO

Content language doesn't equal viewer country. A Spanish-language streamer can draw an audience from a dozen countries, and some of those viewers will be in places where the brand has no license or where gambling ads are banned. Ask for a country breakdown and calculate the share of viewers in your target GEO: that's the part worth paying for.

3. Real engagement

Look past the follower count to what happens during the stream and after the post goes live:

• a ratio of average viewers to followers without sharp, unexplained spikes;
• a chat where people talk to the host and to each other instead of repeating identical phrases;
• comments about the video's topic, not strings of emojis;
• Telegram post views that grow gradually rather than piling up in the first few minutes.

4. Past integrations

Scroll back through the last six months. Which operators has the creator already promoted, and were they licensed in the creator's GEO? How do they deliver an integration — natively or rattled off at speed? Any strikes or bans? A creator who was promoting an unlicensed casino yesterday is a reputational risk for both the brand and the agency.

How to measure: promo codes, links, sub-IDs and landing pages

Measurement is set up before the placement goes live, not after. Each creator and each placement gets its own identifier; otherwise the result dissolves into organic.

• Promo code. Catches people who didn't come through the link: they saw the stream and typed the address by hand. It should be short and easy to say out loud.
• Personal link. A separate one for each creator and each placement spot: description, chat, pinned message.
• Sub-ID. A tag in the link that passes through the tracker all the way to registration and deposit. It lets you tell the stream on the 3rd apart from the stream on the 10th.
• Dedicated landing page. A page for a specific creator: their visuals, their promo code, the mandatory 18+ and a responsible gambling block. It gives you clean stats and usually converts better.

Agree in advance on the attribution window — for example, 30 days from the placement — and on what counts as the target action. That removes half the disputes at reconciliation.

Risks: fake engagement and the wrong audience

Fake engagement. Bots among stream viewers, bought followers, inflated post views. Warning signs: flat graphs with no daily rhythm, identical messages in chat, lots of clicks with almost zero registrations. Protection: a hybrid model, a test placement before a package deal, and a contract clause that gives you the right not to count suspicious traffic.

The wrong audience. Minors, viewers from countries where the brand isn't licensed, bonus hunters who sign up for the promo and leave. This isn't just an efficiency issue; it's a compliance issue too. How to agree on quality criteria before launch is covered in our article on traffic quality and fraud.

Pre-launch checklist for an integration

1. The brand is licensed in every country where the creator's core audience lives.
2. The integration format is allowed under the platform's rules on the go-live date.
3. You have analytics screenshots: age, countries, average viewers or views.
4. The creator's integrations from the last six months have been reviewed.
5. The payment model is chosen; the target action and attribution window are in writing.
6. A personal link, sub-ID and promo code have been issued; a dedicated landing page too, if needed.
7. The integration and the landing page include 18+ and responsible gambling information.
8. The integration is labeled as an ad under the platform's rules and local law.
9. The contract covers traffic quality and content takedown in case of violations.
