An affiliate creative kit is the set of approved files and words a brand hands to the partners who promote it: logos, banners, product images, swipe copy, and the rules for using them. It is a brand guideline written for people outside the building, who will place your work next to their own.
That audience changes the brief. Partners work with a blog template, a newsletter tool and about ten minutes per promotion. A good kit gives them assets that already fit those places, and copy they can adapt without drifting off message.
Done well, the kit protects the identity you paid for and lifts what partners earn, because promotions that look native to their channel get read. This framework is for brand and design teams setting up an affiliate program, or tidying one that has been running on whatever files were lying around.
The kit has five parts. Build them in order.
The five parts
1. A one-page brand sheet partners will actually read
Your internal guidelines might run to 60 pages. Partners need one. Put the logo in its main and reversed versions, as SVG and PNG, with the minimum size and the clear space around it. Add the two or three colours a partner is likely to need, with hex codes, and the one typeface for headlines if it is freely available.
Then show what not to do. Adobe’s guidance on brand guidelines notes that stretching or changing a logo’s proportions weakens it and looks unprofessional. Partners do this constantly, usually to squeeze a logo into a sidebar slot. Three small “don’t” examples (stretched, recoloured, placed on a busy photo) prevent more mistakes than a paragraph of rules.
2. Banners designed for where partners post
The classic affiliate banner is a 300 by 250 rectangle with a gradient, a product shot and a button. It is also the format readers have learned to skip. Nielsen Norman Group’s eyetracking research on banner blindness found that people ignore elements with ad-like placement, like the right rail, and ad-like treatment such as animation, even when the content is useful.
So design fewer ad-shaped banners and more editorial assets: a wide in-article image that reads like a captioned product screenshot, a plain comparison graphic a reviewer can drop between paragraphs, and square and tall versions for social posts and stories. Keep the brand recognisable through colour and type, and let the layout borrow from the page it will sit on.
Export every banner at the sizes partners use, name the files by size and date, and avoid baking prices or offers into the artwork. When the offer changes, a text overlay is easier to replace than 14 PNGs.
3. Swipe copy that can be rewritten
Swipe copy is the pre-written text partners paste or adapt: a one-line description, a short paragraph, a longer review-style section and a few email subject lines. Write each one in plain language and keep the claims checkable.
The useful part is the guardrails around it. List the three claims partners may make, the words they should avoid (absolutes like “guaranteed” or “free forever” if they are not true) and a sample disclosure line saying they earn a commission. Partners will rewrite your copy anyway. Giving them the boundaries keeps their version accurate.
4. Product images that stay current
Reviewers and comparison sites need images of the product itself: interface screenshots, packaging shots, or short screen recordings for software. These date fast. An old dashboard screenshot in a partner review makes the product look abandoned.
Shoot or capture them on a neutral background, at a consistent crop, and refresh them with every visible release. Put the capture date in the filename so partners can tell which version they have.
5. One home for the kit
A kit spread across a shared drive, an old email and a Dropbox link will not be used. Partners should find every file in the same place they collect their links and check their earnings. Affiliate platforms typically include an assets library in the partner portal, and software that keeps the portal fully branded means a partner downloading your banners sees your logo and colours rather than a vendor’s. For a design-led brand, the partner portal is part of the identity too.
Whatever you use, keep one current version of each asset there and archive the rest. Two versions of the same banner will both end up live.
Putting the kit together
Start with the brand sheet, because every other part depends on its decisions. Then write the swipe copy, since banner headlines should come from it rather than be invented in the layout. Design the banners and product images last, and test them by placing them in a real partner’s blog template or newsletter before you publish the set.
Ask two or three active partners to try the kit before launch. Watch where they hesitate: a missing size, a logo that disappears on their dark theme, a claim they are unsure about. Each of those is a gap to fix before the wider launch.
Set a review date every quarter. Check which assets partners actually download and which ones appear on their pages, retire the ones nobody uses, and update screenshots after each release. Partners keep using a kit that stays current, and that keeps the brand consistent on pages your own team will never touch.
The short version
Treat affiliate partners as an extension of the design team with less time and no context. Give them one page of rules, assets shaped for their channels, copy with clear limits, current product images and a single place to find it all. If there is only time for one part this month, make it the brand sheet, since the banners and copy inherit its decisions.
