1 · The persona, the way an agency builds it for you
Let's take the classic method again, without caricaturing it, because it has its logic. A branding agency builds you a sheet: a first name, a photo, an age, a job, an income bracket, goals, frustrations, a sample quote, her preferred channels, her day. The idea is sound: putting yourself in someone's shoes rather than speaking to "a target" in the abstract.
Often, you get three of them. The primary persona, the core target, the one you want to convince first. The secondary persona, the one who influences the purchase without deciding it, the partner or the manager for instance. Finally, the negative persona, the profile you want to keep away, because it costs a lot and leaves fast. Three portraits, one workshop, a nice document.
This exercise has real value, and it always will: it aligns a team on who you're talking to. The catch hides right after, in the implicit promise nobody spells out.
2 · The persona was never a targeting tool. It was a creative brief in disguise.
The implicit promise is this one: "once Marie is defined, we find her again in the ads". You translate the portrait into criteria, you tick the interests, and you push the ads onto that audience. The persona becomes a targeting instruction.
Except it was always mediocre at that job. An interest like "yoga" lumps together the dedicated practitioner, the one who liked a page three years ago, and the influencer reselling mats. People lie about their age, change their minds, spill out of every box. Targeting by demographics is aiming at a silhouette in the fog. It worked well enough because we had nothing better.
What the persona has always done well, on the other hand, is give the team a face to write for. A tension to name, an objection to lift, words to use. That isn't targeting, it's a creative brief. We confused the two for fifteen years for a simple reason: you were the one targeting, so the same sheet served both uses. The two jobs were glued together. They just came apart.
3 · The world where you did your own targeting is over
First, give the old world its due, because it worked very well. For years, targeting by hand was a real craft, and its sharpest weapon wasn't even interests: it was the lookalike audience. You handed Meta your customer list, or your buyers collected by the pixel, and the platform went off to hunt down their statistical twins, the people who resemble them without knowing you yet. Well fed, a lookalike put out results with a regularity you almost miss. Manual targeting wasn't always an illusion. It had its golden age.
Two things ended it. Apple's 2021 update, which cut part of the pixel signal, starved the material lookalikes fed on: smaller, blurrier seeds, less reliable twins. Above all, Meta's engine eventually learned to do that "find people who resemble your buyers" job on its own, but at the scale of the whole platform. The lookalike you built by hand, the algorithm absorbed, then industrialized. That's what opens the next era.
That next era has a name: Advantage+. Meta's automated targeting treats your inputs as suggestions, not as rules. You can still fill in an age, an area, interests, but the algorithm reads them as a starting point. Only location and minimum age stay hard constraints. For the rest, it begins from your hints, then expands toward the pockets of audience that convert better, even if they have nothing to do with your sheet.
This shift is no whim of Meta's. The engine that delivers the ads was rebuilt around artificial intelligence in late 2024, and it learns by analyzing the ads and the reactions, not by following your targeting to the letter. According to Meta's own benchmarks, AI-driven broad targeting runs up to 30% lower cost per acquisition than manual targeting. We get into that logic in detail in our article on Meta Ads account structure, but the gist holds here: your beautiful interest targeting, set up around Marie, the algorithm receives it as a suggestion and overrides it.
The consequence is brutal for the persona as we practised it. The box you filed Marie into is barely useful anymore. If the machine targets better than you, what's the point of describing her? The answer is in the next part, and it puts the creative back at the centre.
4 · The creative became the targeting
Here's the move to keep in mind: targeting didn't disappear, it changed location. It moved from the demographic box to the ad itself. A video that opens on "Nurses, this one's for you" will find nurses better than any interest segment, because the system watches who stops, who clicks, who buys, and goes looking for more people like them. The ad selects its audience through what it shows and what it says.
In practice, fine targeting now lives in the hook, in the first three seconds, in the exact word that makes someone think "that's me". A generic creative speaks to everyone and catches no one. A creative that names a precise situation catches the people in that situation, and the algorithm takes care of finding their lookalikes. Fine targeting, the kind you did by hand, now happens through the specificity of the message.
To make it concrete, take a weekly meal-prep service for time-poor parents, and look at how the campaign flow changed. The old flow, five years ago: persona workshop, you draw Marie; you translate her into boxes, women aged 30 to 40, interests "cooking" and "parenting"; a polished, on-guideline creative pushed onto that audience; if results disappoint, you tighten the audience. The new flow, the one we run on missions: you pull ten real triggers from the comments and reviews; each trigger becomes a hook; you produce ten raw, varied creatives, one per angle, and let broad targeting sort them out; if results disappoint, you don't touch the audience, you change the angle. Before, all the effort went into the box. Now, it goes into the message.
That's why Meta rewards volume and creative variety over finely sliced targeting. Ten genuinely different ads beat three variants that look alike, because each one fishes in a different pocket of audience. We set the frame for this shift in the craft in our article on creative and UX driven by live data. What matters here is the logical next step: if the creative targets, then the persona has to serve the creative.
5 · The targeting persona is obsolete, the brief persona is back in force
Put the two findings together. The demographic persona targets badly, and the machine isn't listening to it anyway. No surprise that 62% of marketers say their personas no longer reflect their customers' real behaviour. The reason is always the same: they're built on assumptions made in a workshop, with no data behind them. The invented sheet is dead, and nobody mourns it.
But look at which one died. It's the identity persona, the one that served to target on guesses. The persona that feeds the creative has never been more useful, precisely because the creative became the targeting. The portrait changes jobs: it leaves the ad manager and enters the creative brief. We declare the persona dead at every new era of the medium, and every time it's the wrong version that dies, while the right one comes back through the side door.
That leaves the real question: how do you build a persona that holds this new role? A persona grounded in the real rather than invented, alive rather than frozen in a PDF, and above all run as a system rather than filed as a sheet. This is where the theory becomes a method, the one we run on missions. Three moves.
6 · First move: start from the real, through social listening
A real persona isn't invented in a workshop, it's listened to. The first move is social listening, meaning combing through what your customers and prospects actually say, in their own words: the forums in your sector, customer reviews, help pages, and above all the comments under the ads, yours as well as your competitors'. You don't decide Marie's tension, you go read it where she expresses it unfiltered.
The effect on the creative material is immediate. Starting from a workshop, you get one angle: "our target wants to save time". Starting from real conversations, you get dozens of distinct triggers, those precise little reasons that tip someone into buying: the fear of getting it wrong, being fed up with a competing tool, a deadline, a comparison, a bad past experience. Each trigger is a potential ad angle. You no longer have a persona, you have a bundle of usable tensions.
Each trigger hands you its line, almost word for word. "I feel guilty ordering pizza on a Tuesday night" becomes "Nobody wants to cook on a Tuesday night, here's how to skip it". "I'm done racking my brain over what to make" becomes "The real chore at night isn't cooking, it's deciding what to cook". "The kits I tried were full of plastic" becomes "Your week of meals, without the three plastic bags of the last kit you tried". Three tensions, three hooks, three ads that don't speak to the same people, where the old sheet produced just one: "save time".
It's also a change of anchor point. We stop defining people by their identity (age, job, income) and start defining them by their situation and their intent, what the trade calls the "job to be done", the jobs-to-be-done. Marie's age doesn't say why she buys. Her trigger does, and it hands you the hook line directly. That line is what does the targeting for you.
7 · Second move: deploy the persona across the whole funnel
Having triggers isn't enough, you need a path to play them. The second move is a real funnel logic, that trade word for the tunnel through which a stranger becomes a customer: the top where you're discovered, the middle where you're researched, the bottom where people buy. Many brands do almost nothing but bottom-of-funnel, "buy now" ads pushed onto people already ready. The pool is tiny, and it runs dry in a few weeks. That's the immediate burnout we see most often in audits.
The fix comes in two steps. First, reallocate the creatives across the whole funnel, with plenty of educational top-of-funnel: sharp concepts, podcast formats, creatives that explain and demonstrate instead of selling right away. That content feeds the machine, widens the audience and supplies the bottom of the tunnel instead of draining it. Second, wire up a funnel per persona: for each profile, you adapt the three stages at once, the creative, the page the ad runs from, and the landing page.
That last point deserves a word, because it makes the difference. The page the ad runs from is the account in whose name the ad appears. Running it from the account of a creator or a trusted partner, rather than from your brand account, is called whitelisting or partnership ads. The same message doesn't land the same depending on who seems to be saying it. For one persona, the word of a credible peer beats the brand's; for another, it's the opposite. A complete persona today isn't a face, it's a coherent path from end to end, repeated for each profile.
8 · Third move: creative diversity, or how to optimize a system
The third move is the most misunderstood, because it looks like a production problem when it's a probability problem. To multiply the chances of finding winning ads, you have to multiply the attempts. On a mission, we went from 12 to 75 creatives produced per month, with 7 to 10 different creator profiles each month, each one embodying a distinct persona. Far from being waste, that volume is test surface: the more attempts you open, the better the algorithm's chances of landing on a winner.
That volume comes at a price worth naming, because Meta pushes you straight toward it. To perform in the feed, an ad often has to stop looking like an ad: a screenshot, a quickly shot selfie video, plain text, a meme. These are "ugly ads", and they regularly beat the polished creative, precisely because they don't trigger the "oh, an advert" reflex that makes people scroll. The flip side is that you step outside your brand guidelines: the clean framing, the well-placed logo, the brand colours, everything that screams "advertiser" can drag the delivery down. Pump them out by the dozen and you take a real risk with your image, because a feed saturated with raw, mismatched creatives can dilute what your brand stands for.
This trade-off is steered, not suffered. The feed isn't your website: an ugly ad that converts can sit perfectly well alongside a polished identity on your brand pages and your brand campaigns. The rule we hold on missions is to keep a core faithful to the guidelines for the brand-building work, and open a looser "performance" lane next to it, where stepping outside the guidelines is allowed as long as the creative stays true and aligned with the persona's trigger. Stepping outside your guidelines isn't betraying your brand, it's speaking the language of the feed. But it's a decision, not a drift.
The right way to think about it is to stop thinking "audience" and start thinking "system". What you optimize isn't a target anymore, it's a product of four dimensions: media times creative times funnel times persona. Each persona, times each funnel stage, times each creator profile, times each format, opens a combination to test. The algorithm hunts for winners in that space. The richer and more varied the space, the more it finds. One perfect ad leaves it no room; seventy-five sincerely different ads leave it plenty.
The underlying constraint remains: it demands a production pace few outfits can hold. It's the change of craft that creative agencies moving into performance are living through, and it's the system we assemble on the paid acquisition side, brick by brick, rather than one big ad designed in a single block. The persona is no longer the finish line. It's one of the four dimensions we keep turning.
9 · The real question is no longer "who is your target", but "who are you talking to in each ad"
Put the whole mechanism back together and the persona finds its place again, without throwing away any of the old craft. It stopped being the line you type into the ad manager. It became the brief behind every creative angle, the source of the language, the map of the funnel. Same tool, new job. The persona doesn't die, it changes roles.
The reflex to change is right there: stop asking only "who is my target" to tick it somewhere, and ask yourself "who am I talking to, precisely, in this particular ad". The answer lives in the creative now, more than in the targeting. A persona grounded in the real gives you that specific language; the machine takes care of finding the people who react to it. It's the same logic as the rest of the digital craft: technology automates the mechanical work, and sends you back to the work that counts, truly understanding who you're talking to. We saw it for search in our article on GEO and the definition of SEO, we see it again here for advertising.
One honest caveat to finish, because the rule isn't absolute. The old targeting persona still makes sense in a few precise cases: a brand-new account with no conversion history, a very local campaign, a niche B2B market with little volume, or a small budget. There, tight manual targeting, built from a narrow persona, still beats the AI's broad exploration, because the machine doesn't have enough material to learn. For everything else, and that's the majority of accounts with volume, the persona has moved into the creative. If you want us to build this system with you, from social listening all the way to creative diversity, that's what we do on strategy missions. Otherwise, you have the method: listen to the real, write for the creative, keep the system turning.
