The brands your buyers already trust, and why nobody's tracking it

SparkToro quietly shipped a feature that shows which companies an audience is already familiar with and already buying from. It is not a new idea. It is just the first time anyone made it easy to check.

TL;DR · 60 SECONDSSparkToro added a Brand Affinity section to its audience research reports in July 2026, showing which companies, products, and brands a given audience already knows and buys from, built from existing keyword, LinkedIn, and clickstream data. It is a small feature with a big use case: instead of guessing at competitors and influences, you can now look them up. The catch is that familiarity is not endorsement, and a list of trusted brands tells you what to reference, not what to copy.

Every content strategy deck has a slide with a made-up persona on it. Jane, 34, VP of Marketing, drinks too much coffee, reads three newsletters nobody can name. The slide exists because building a real picture of an audience used to take a survey budget and six weeks nobody had. SparkToro just made a chunk of that picture available in about four clicks, and almost nobody outside their own customer base has noticed yet, which is exactly the kind of quiet feature release worth paying attention to before everyone else catches on.

What brand affinity data actually is

The feature is simple to describe: search or select an audience the way you already would in a SparkToro report, and a new Brand Affinity section under "Keywords and Prompts" surfaces the companies, products, and brand names that audience is most familiar with and most likely to have purchased from. It draws on data SparkToro already had, keyword behavior, LinkedIn profile signals, and clickstream data, rather than a new survey instrument. According to the company, cofounder Casey had been sitting on customer requests for this for a while before finding a way to assemble it from data already on hand, describing it as a few weeks of tweaking rather than a from-scratch build.

Example
Gaming, nostalgia-drivenFor an audience of nostalgic indie game enthusiasts, the tool surfaced Humble Bundle, Kotaku, and Devolver Digital as the highest-affinity brands.
Example
Men's formal wear, 30-40For men aged 30-40 buying tailored suits, the surfaced brands were Suit Supply, Brooks Brothers, Proper Cloth, and Indochino.

Neither example is a shocking result on its own. That is sort of the point. The value is not that the tool reveals something nobody could have guessed, it is that it replaces guessing with a lookup, for audiences a team does not already know intuitively. A marketer who has spent five years in men's fashion could probably have named Brooks Brothers unprompted. A marketer who just picked up a new vertical, or a new international market, cannot, and that is exactly the situation this tool is built for.

That situation comes up more often than most teams admit out loud. Agencies pick up new verticals every quarter. In-house marketers get reassigned to a product line they didn't grow up following. A content team hired to cover fintech last year gets handed the healthcare account this year, and the honest starting knowledge of that new audience is close to zero, no matter how confident the kickoff deck sounds. The old fix was a rushed round of stakeholder interviews and a lot of nodding along to whatever the loudest person in the room claimed to know about the space. The new fix is closer to a search bar: type in the audience, read the list, go verify the parts that matter before betting a quarter's content calendar on them.

Why this is more useful than another persona slide

Traditional audience personas are built from a mix of internal customer data, a handful of interviews, and a lot of educated guessing dressed up as research. They tend to be built once, presented with confidence, and then quietly ignored the moment a real campaign decision has to get made, because nobody trusts a document nobody can re-check. Brand affinity data is re-checkable by design: it is a live lookup against current behavior, not a snapshot frozen the quarter someone ran a research sprint. That matters more for content strategy than it sounds, because the fastest way for a content calendar to go stale is for it to keep targeting an audience's assumed interests two years after those interests moved.

The companies, products, and brand names an audience is most familiar with and/or purchases from.

That plain description, straight from SparkToro's own framing of the feature, is worth sitting with, because it draws a line the tool itself does not claim to cross: familiarity and purchase history, not preference or loyalty. A brand showing up in an audience's affinity list means that audience knows the brand and has likely bought from it, not that the audience loves it, would recommend it, or wants to hear it referenced in every piece of content going forward. Reading it as anything stronger than that is where teams get into trouble, a point worth returning to below.

It's also worth noticing what the feature deliberately doesn't try to be. It isn't a sentiment tool, it doesn't score a brand as loved or disliked. It isn't a forecasting tool, it doesn't predict which brand an audience will trust next year. It's closer to a very fast, very current version of the question a good salesperson used to answer from memory after a decade in the territory: who else does this buyer already know. Turning that into a lookup instead of a decade of tenure is the real value here, and it's a smaller, more honest claim than most new marketing tools make about themselves.

Two ways to actually use it

1Agency and consultant pitchesShowing a prospective client the actual brands their audience already trusts, pulled live rather than from a stock competitive-analysis template, is a faster way to demonstrate category expertise than another generic slide of logos.
2In-house content and campaign planningStudying which brands and publications an audience already engages with gives a content team a real reference list, who to consider quoting, comparing against, or studying the tone of, instead of an internal brainstorm about who the competition probably is.

The second use case is the one worth building process around. A content team that knows which outlets and brands its audience already reads can make sharper decisions about where to pitch, what tone to match, and which comparison content to build first. We have argued elsewhere that comparison and alternatives content does disproportionate work in both organic search and AI-search visibility. Brand affinity data is a fast way to decide which comparison to build first: the brand your audience already associates with the category, not the one your internal roadmap happens to be obsessing over this quarter.

The catch

Familiarity is not the same signal as trust, and trust is not the same signal as intent to switch. A brand can top an affinity list because it is the default, the incumbent everyone already uses and nobody is especially excited about, which is a very different strategic situation than topping the list because it is genuinely well-loved. The data does not distinguish between those cases on its own, and a team that reads a high-affinity competitor as automatically beloved is making the same mistake as the team that used to write a persona from a hunch: mistaking a plausible-sounding number for a verified one.

APPROACHWHAT IT ACTUALLY MEASURESWHERE IT BREAKS DOWN
Made-up persona slideA team's internal assumptions about the audienceNever updated, rarely challenged, often wrong from day one
Customer interviewsDeep, qualitative signal from a small sampleSlow, expensive, and easy to over-generalize from a handful of conversations
Brand affinity dataLive familiarity and purchase behavior at audience scaleMeasures exposure and history, not sentiment, loyalty, or intent to switch

The honest way to use this data is as a starting hypothesis, not a finished answer. If an audience's affinity list surfaces a brand a content team has never seriously considered a competitor or reference point, that is worth investigating further, through the same qualitative work, customer interviews, sales call reviews, dashboard metrics that actually hold up under scrutiny, that any real strategy decision deserves. What the tool changes is the starting point of that investigation. Instead of beginning from a guess, a team begins from a list of names it can actually go verify, which is a meaningfully shorter path to a decision worth trusting.

There is a specific failure mode worth naming, because it will happen to somebody's Monday content brief within a month of this feature getting popular: a junior strategist pulls the affinity list, sees a brand at the top, and writes a brief that treats that brand as the audience's favorite without ever checking why it showed up there. Maybe it's the market leader everyone has to use because there's no real alternative yet. Maybe it's a brand the audience associates with a bad experience they complain about constantly, which still counts as familiarity and purchase history even though it is the opposite of an endorsement. The data cannot tell the difference between those two stories on its own. A five-minute sanity check, a quick search for how people actually talk about that brand, closes the gap the tool leaves open, and skipping that step is how a genuinely useful shortcut turns into a genuinely embarrassing brief.

Where to start Monday

Pull the affinity data for your two or three highest-value audience segments before the next content planning cycle, not as a replacement for existing customer research but as a cross-check against it. Where the affinity list agrees with what the team already believes, that is confirmation worth noting in the brief. Where it surfaces a name nobody expected, that is the one worth a real conversation before the next quarter's content calendar gets locked, especially for a B2B SaaS team whose buyer research budget rarely stretches to a proper interview sprint every quarter. Pair the finished list with a content marketing engagement built to act on it, not just present it. A tool that turns a guess into a checkable list is not a strategy on its own. It is just, finally, a cheaper way to find out whether the guess was right.

None of this is a reason to wait for a more sophisticated version of the feature before using it. Small, checkable tools that replace a guess with a lookup tend to get more valuable as teams build habits around them, not less, and the habit worth building now is treating an affinity list as the first ten minutes of a research process rather than the whole thing. The teams that build that habit early will be running sharper briefs by the time everyone else finds the feature buried under the Keywords and Prompts dropdown.

KEY TAKEAWAYBrand affinity data replaces guesswork with a lookup: which brands an audience already knows and buys from. It is a strong starting hypothesis for content and competitive strategy, not a finished verdict, because familiarity is not the same thing as loyalty or intent to switch.
