A performance-led brief is a one-page brief that starts from what your last posts actually did. You pull the best and worst posts from the last 90 days, write down the pattern, and tell the creator to repeat it with one new thing to test. It swaps opinions for evidence.
TLDR: Spend 20 minutes in your analytics before you write the brief. Fill in seven fields on one page: goal, audience, proof, message, formats, test, success number. After the campaign, review the results against that page and update the proof for the next brief.
Why most briefs do not change the work
A typical brief says "increase awareness" and "keep it on brand". A designer cannot do anything with that. They end up guessing, and the guess is usually whatever they did last time.
A performance-led brief changes one thing: it puts your own results at the top. Instead of "make it engaging", it says "our carousels ran 10% above our typical post, and posts with a link in the caption ran 7% below".
In Mydrop's data, carousels ran 10% above the account's typical post and a link in the caption cost 7%. Your account may differ, which is why you pull your own numbers.
Pull the proof first, in 20 minutes
Open your analytics for the last 90 days and write down four things:
- Your median post. The middle result, not the average. It is your yardstick.
- The top three posts. What format, hook and time of day did they share?
- The bottom three posts. What did they share?
- One surprise. Something you did not expect.
If you manage several brands, do this for each one. A pattern from one brand rarely holds in another.
The seven-field brief
| Field | What to write | Example |
|---|---|---|
| Goal | One outcome | 150 signups to the webinar |
| Audience | One group, one sentence | Marketing leads at small agencies |
| Proof | Two lines from your analytics | Top 3 posts were carousels with a number in the first slide |
| Message | One sentence the viewer should remember | Reports in one click |
| Formats | Two at most | Carousel, 30-second video |
| Test | One thing that changes | Hook starts with a question vs a number |
| Success number | One metric and a target | 4% saves rate, above our 2.5% median |
Seven fields is the limit. Every extra field dilutes the ones that matter.
Write the test into the brief
The most useful field is "test". A brief without a test only repeats the past. A brief with one test teaches you something every campaign.
Rules for a good test:
- Change one thing. Hook, image or call to action. Not all three.
- Make it small enough to run twice. One result is a story. Two is a pattern.
- Say how you will read it. "Compare saves rate against our median" is clear. "See how it does" is not.
Hand it over so it gets used
Send the brief to where the work happens. A PDF in an email is read once. A note attached to the scheduled post is seen every time someone opens it.
In Mydrop, you can attach the brief to the post on the calendar, so the designer, the writer and the approver all see the same goal. Reviewers can comment right on the draft through approvals, and the AI caption and post idea tools in AI content creation can use the proof lines as a starting point for drafts.
Review against the page, not against feelings
After the campaign, open the same brief and fill in two more lines:
- Result: the success number you got.
- Learning: what you will repeat, drop or change.
Then copy the learning into the proof field of the next brief. After a few cycles, your brief becomes a record of what works for your accounts, and new team members can read three briefs and understand your whole approach.
If your analytics live in one place, the review takes ten minutes. Mydrop's performance analytics show each post against your account's typical result, so you can fill in the numbers without a spreadsheet.
Brief for agencies and clients
If you send briefs to clients for approval, keep the proof field. Clients accept direction faster when they can see their own numbers behind it. It also gives you a clean record when someone asks "why did we do this?" three months later.
Write your next brief in 30 minutes
Open your analytics, pull the median and the top and bottom three posts, then fill in the seven fields. Send it with the first draft rather than before it, so the creator can react to something concrete. Next time you have a launch, try it in a free Mydrop account with the brief attached to the post.
