TLDR: Influencer marketing and affiliate marketing are more powerful together than they are apart. By treating creators as performance partners, you can track real sales, optimise what’s working, and build a programme that grows over time.
For a long time, influencer marketing and affiliate marketing lived in separate boxes. Influencer was a brand awareness play, difficult to attribute, hard to justify on a spreadsheet. Affiliate was a performance channel, trackable, commission-based, and reassuringly measurable. But the line between the two has been blurring for years, and the brands getting the most out of their creator relationships are the ones that have figured out how to connect them.

Step 1: Decide on your creator affiliate model
Before you recruit a single creator, you need to decide how you want to work with them. There is no single best approach, it comes down to what you want the brand wants to achieve and the type of creators you plan to work with.
There are three main models to consider:
- Commission only: The creator earns a percentage of every sale they drive, just like a traditional affiliate setup. This is low-risk for the brand, scalable, and works well with smaller creators who already have an audience aligned with your product. It requires no upfront spend, but the incentive for creators to produce high-quality, sustained content is lower.
- Flat fee plus commission: This is the most common way to work with creators today. You pay for the content upfront, guaranteeing that it gets made and made well, and add a commission on top to keep the creator invested in performance. It works particularly well with mid-tier influencers and strikes a balance between reach, accountability, and ongoing motivation.
- Tiered commission: You can also build in escalating commission rates based on performance thresholds. For example, a creator might earn 10% on the first £5,000 of revenue they drive, and 15% beyond that. This gives creators a clear reason to keep pushing and rewards those who consistently perform.
In practice, the best programmes often use a mix of all three, applying different models to different creators depending on their size, the KPIs you are working towards, and what the platform you are running the programme on supports.
Step 2: Choose where to run your creator affiliate programme
Once you have decided on your commission structure, you need to choose the platform or network through which you will run it. There are three main options, and each has its own trade-offs.
The first is your existing affiliate network. If you are already running an affiliate programme through a network like AWIN, Webgains, or Impact, the simplest approach is to extend that programme to include influencer creators. This keeps your tracking, commission structure, and reporting in one place. Modo25 works across all three of these networks, and as a Certified Agency Partner and Impact Certified Product Expert, we have a particular depth of experience in getting the most out these networks.
The downside of this route is that not all affiliate networks have kept pace with the growth of influencer marketing. Some lack dedicated creator sections, discovery tools, or the kind of scale needed to recruit influencers at volume. If that is the case for your current network, then one option is an influencer-specific publisher platform, such as LTK or Metapic. These platforms have large creator communities already signed up, account managers who have a deep understanding of the publisher type, and discovery tools that make it much easier to find the right fit for your brand, particularly in fashion, lifestyle, and beauty. The trade-off is that you are working with an external publisher, which may involve a hefty onboarding fee.
The third option is TikTok Shop Affiliates, which has grown rapidly and works particularly well for brands with a strong presence on the platform. It is possible to combine all three approaches, running your core programme through an affiliate network while using creator platforms for discovery and TikTok Shop for native commerce, or to start with one and expand from there.
Step 3: Identify and recruit creator affiliates
Finding the right creators is one of the most important steps in the process and it is often more hands-on than people expect. There is no single method that works for everyone, so most programmes use a combination of approaches.
Start by looking at who is already on your affiliate programme. It is not uncommon for smaller influencers or content creators to have signed up organically. They may not be driving huge volume, but if they are already aligned with your brand, they are worth reaching out to and exploring how to scale the relationship.
From there, you can search within your affiliate network for creators in relevant categories and review their performance history. Tools within platforms like LTK and Metapic make this easier, especially for lifestyle and fashion brands, with built-in discovery functionality and creator recommendations from account managers who understand their roster.
Beyond the platforms, social media is an underused recruitment tool. Look at who is already using your brand hashtags, tagging your products, or creating content about competitors. If someone is organically engaged with your category, they are a warmer prospect than a cold outreach. It is also worth simply paying attention, if a team member follows a creator whose audience closely matches your target customer, that is a legitimate starting point for an outreach conversation.
Whichever method you use, the same criteria apply: look for creators who are driving consistent engagement, whose audience genuinely aligns with your product, and who already understand your brand or category. Authentic fit matters more than follower count.
Step 4: Set up tracking for creator-driven sales
One of the main reasons to run influencer activity through an affiliate programme is that you can track it and tracking creator-driven sales is considerably more straightforward when it sits within an affiliate network than when it lives in a standalone influencer arrangement.
The two most common tracking methods are unique affiliate links and promo codes.
Each creator on the programme gets their own unique URL, which tracks every click and every sale back to that specific creator. This gives you a clear view of the revenue they are driving and makes it straightforward to calculate commission and make decisions about ongoing investment.
Promo codes work well for the creator and are particularly useful on social platforms where a clickable link is not always possible. A personalised code (something specific to the creator, rather than a generic discount code) can be linked within your affiliate network to that individual publisher. Any sales made using that code are then attributed to them directly. Personalised codes also tend to perform better because they feel more authentic to the creator’s audience.
For reporting, the affiliate network is generally the primary source of truth for creator performance. If the brand is also using GA4 or another analytics platform, it is worth cross-referencing both to build a fuller picture, but the network data is where you will typically find the clearest view of what is driving revenue.
Step 5: Brief creator affiliates for performance, not just reach
A good creator brief for an affiliate programme is different from a standard influencer brief. You are setting up a partnership, and the brief needs to reflect that.
The brief does not need to be prescriptive. Creators know their audience better than anyone, and over-scripting their content is one of the fastest ways to make it feel inauthentic. What it does need to provide is enough clarity that the creator can produce content that actually works.
A solid creator affiliate brief should cover:
- The focus message: What specific product, range, or launch do you want them to talk about? Give them the key information without writing their script for them.
- The link or code: Make sure they have their unique affiliate link and/or promo code before they go live. This is the tracking mechanism, without it, you cannot attribute their sales.
- Brand guidelines: If there are things you do not want them to say, mention competitors to avoid, or a tone of voice to maintain (particularly important for premium brands), include this clearly.
- Content expectations: If you are paying a flat fee, be clear on how much content you expect in return, number of posts, platform, timeframe.
- ASA compliance: Include a reminder about disclosure requirements. Creators are required by law to label sponsored content, but it still gets missed. Providing a link to the relevant ASA guidelines is a simple way to ensure everyone is clear and protects both the creator and the brand if the content is ever scrutinised.
For product-led brands, it can also be worth including supporting information, ingredients, how-to-use guidance, or product recommendations, particularly if the creator is newer to your category and could benefit from that context to make their content more credible and useful.
Step 6: Amplify high-performing creator content as paid ads
Once creator content is live and you can see what is performing, the next step is amplifying it. Content that is already resonating organically is a strong candidate for paid distribution, it has already demonstrated that it connects with an audience, which reduces the guesswork involved in paid social creative.
The most common way to do this is through Meta Partnership Ads (formerly known as branded content ads) on Instagram and Facebook. When set up correctly, the post appears to come from both the brand and the creator, it shows ‘in partnership with’, giving it the authenticity of creator content with the targeting precision of a paid ad. TikTok Spark Ads work on the same principle, allowing you to boost an existing creator post directly from your brand’s ad account.
This is where the relationship between your influencer programme and your paid social team becomes important. If a creator’s organic post is driving strong affiliate link clicks and conversions, that is valuable signal. Sharing that data across teams means the paid social team can make informed decisions about which creator content to put spend behind.
Usage rights should ideally be agreed upfront in the creator brief or contract, so that there is no need to renegotiate when a piece of content outperforms expectations.
Step 7: Measure creator affiliate performance beyond last-click
Affiliate networks traditionally attribute sales on a last-click basis, meaning the last touchpoint before purchase gets the credit. For creator-driven activity, this can significantly understate the value of what your creators are actually doing. A customer might discover a brand through a creator’s Instagram post, research it on Google, and then convert through a paid search ad. On last-click, the creator gets nothing. In reality, they initiated the journey.
The key metrics to track within your programme are:
- Click-to-sale conversion rate by creator: Not all traffic is equal. A creator with a smaller audience but a high conversion rate is often more valuable than one with huge reach and low commercial intent.
- Revenue and commission driven per creator: The clearest measure of performance. Filter your network reports by publisher type to isolate creator-driven activity and rank by revenue contribution.
- Promo code redemption: A useful proxy metric for creators who are primarily active on platforms where link clicks are harder to track.
- Engagement rate on affiliate content: High engagement, especially saves and shares, is a leading indicator of purchase intent, even if the conversion does not happen immediately.
- New customer rate: Are your creator affiliates bringing in genuinely new customers, or are they largely converting people who would have purchased anyway? This is especially relevant when you are paying a flat fee plus commission.
Cross-referencing your affiliate network data with GA4 or your analytics platform of choice gives the fullest picture and is worth doing regularly, not just as a one-off exercise. Over time, patterns in the data will tell you which creators, which content formats, and which commission structures are delivering the strongest return.
Conclusion
Influencer and affiliate marketing are at their most powerful when they are treated as a single, integrated programme rather than two separate workstreams. Creators who are also performance partners are more invested in outcomes. Tracking that sits within an affiliate network is more reliable and easier to optimise. And content that proves itself organically can be amplified with paid spend, extending its impact further.
