How to Build a Media Kit for Brand Partnerships
An email arrives from a brand you have wanted to work with for a year, asking for your rates and audience breakdown. If your next move is scrambling to pull screenshots of your Instagram insights into a blank document, you are already negotiating from a disadvantage. A media kit is not just a summary of your follower count; it is a structured argument for why a brand should allocate part of their marketing budget to your audience instead of spending it on paid advertising.
Quick Summary
A media kit is a digital portfolio that creators and freelancers use to prove their commercial value to prospective brand partners. It replaces scattered screenshots with verified performance metrics, audience demographics, and past campaign results.
- Define your audience using specific demographic and purchasing data rather than broad categories.
- Report 30-day average metrics rather than peak viral anomalies to set realistic expectations.
- Frame past brand work as case studies showing the return on investment you generated.
- Host your portfolio digitally to avoid email bounce-backs from massive PDF attachments.

1. Extract your core audience demographics
Brands buy your demographic overlap, not your total reach
Before a brand looks at your engagement rate, they check if your followers are actually the people who buy their products. A total follower count is a vanity metric; the percentage of your audience that matches the brand's target customer profile is the commercial metric. If a UK-based skincare brand wants to sell an anti-ageing cream, they need to know exactly what portion of your audience are UK women over 35.
To build the audience section of your media kit, pull the geographic distribution (top three countries and top three cities), the age brackets, and the gender split from your platform analytics. Do not estimate these figures. Export the exact percentages from your social dashboard.
Beyond basic demographics, include psychographics: what your audience cares about, what they ask you for advice on, and what they have bought based on your recommendation in the past. If you run an online shop alongside your content, include the average order value or the most popular product categories. This proves your audience has purchasing intent, not just scrolling habits.
Practical rule: Never round up your demographic percentages. If a precise share of your audience is female, write the exact figure from your dashboard rather than "about half" - specificity signals that you actually check your analytics.
The mistake creators make here is defining their audience too broadly. Claiming you reach "everyone interested in fitness" makes you sound like an amateur. Stating that you reach "UK-based university students interested in budget meal prep" tells a specific brand that you hold the exact attention they are trying to buy.
2. Compile your performance metrics
Averages establish commercial reliability
Metrics dictate your pricing power. However, presenting your numbers incorrectly will either price you out of the market or leave money on the table. Brands use your metrics to calculate their projected Cost Per Mille (CPM) or Cost Per Engagement (CPE). If your numbers fluctuate wildly, you become a high-risk investment.
Pull your metrics based on a 30-day or 90-day rolling average. You must include your average reach per post, average impressions, engagement rate (likes, comments, saves, and shares divided by total reach), and story views. If you have an email list, include the open rate and click-through rate. If you have a social media kit template, ensure these fields are easily editable so you can update them monthly without redesigning the entire document.
The critical failure mode in this step is cherry-picking data. Many creators use the metrics from their most viral post and present them as standard performance. When the sponsored post inevitably performs at the normal, lower average, the brand feels cheated and will not book you again. A viral spike is an anomaly, not a baseline. Put your viral successes in the case study section, but keep your core metrics section grounded in your 30-day average.
3. Structure past campaigns as case studies
A pretty image proves nothing without conversion data
A list of brands you have worked with is a good start, but it does not tell a marketing director what you actually achieved for those companies. A logo wall proves you were hired; a case study proves you delivered. You must show the mechanism of how your content drove a specific result.
Select three past campaigns that represent the type of work you want to do more of. For each, use a standard structure: the brand's objective, your creative execution, and the measurable result. If a brand wanted to drive awareness for a new product, state the total reach and organic shares your content generated. If the goal was sales, state the number of link clicks, the conversion rate if known, or the total uses of your discount code.
The trap here is treating the case study as an art gallery. Creators often display the final social media poster or video thumbnail without any accompanying data, assuming the aesthetic quality of the content speaks for itself. To a marketer, a beautiful video that drove zero clicks is a failed campaign. You must pair the creative asset with the hard numbers it produced.
4. Format for immediate digital access
Friction in delivery kills the deal
How you deliver your portfolio determines whether it gets read. Marketing managers review dozens of pitches a week. If accessing your data requires downloading a massive file, unzipping a folder, or requesting permission to view a locked drive, they will simply move on to the next creator.
The mechanics of delivery have shifted away from static PDF attachments. A 25MB PDF will often be blocked by corporate email firewalls or crash on a mobile device. Instead, your kit should live online as a mobile-optimised landing page. You can host this on a custom domain or use a centralised link platform. This approach means you only ever send a single URL, and the brand always sees your most up-to-date metrics without you having to recall an outdated file. By linking it directly to your digital social media business cards, you ensure that anyone you meet at an industry event can instantly access your commercial offering with a single tap or scan.
The mistake creators make is over-designing the layout at the expense of readability. Heavy graphics, complex animations, and tiny fonts force the reader to hunt for the numbers. Format the page for rapid scanning: use large, bold typography for key metrics, bullet points for demographics, and clear, contrasting buttons for your contact information.
Where media kits fail to convert
The symptom: Brands praise your content but never reply after you send your rates and portfolio. The fix: Check if your pricing is disconnected from your metrics. If your engagement rate is 1% but you are charging premium rates based purely on your follower count, brands will walk away. Realign your rates to reflect your average reach and conversion metrics, not your total audience size.
The symptom: The brand asks for clarification on your audience location despite you sending the kit. The fix: Your demographics are either missing or buried. Move your top three audience locations and age brackets to the very top of the document, immediately under your bio. This is the most common reason a kit gets discarded.
The symptom: You receive low-ball counter-offers that treat you like a beginner. The fix: You are missing case studies with conversion data. If you only show follower counts, brands assume you cannot drive sales and will only offer basic awareness rates. Add one detailed case study showing link clicks or code uses to prove you can drive measurable return on investment.
FAQ
How often should I update my statistics?
Update your core metrics and audience demographics on the first day of every month. Using outdated numbers from six months ago misrepresents your current commercial value.
Should I include my rates directly in the document?
It depends on your strategy. Including starting rates filters out brands without a budget, saving you time. However, leaving rates off allows you to price each project dynamically based on the specific usage rights and exclusivity the brand requires.
What if I have never done a brand partnership before?
You can build a case study using your own content. Show how you promoted your own product, an affiliate link, or even a specific content series, highlighting the engagement and clicks you drove organically.
Do I need a different version for different platforms?
No. A strong portfolio aggregates your total digital footprint. Break down your audience and metrics per platform (e.g., Instagram vs. TikTok) within the same document so brands can see your cross-platform influence.
