Supplement, apparel, and equipment advertisers keep recruiting the same visible creators. We start from 120M+ classified domains, pull the whole fitness & nutrition vertical, and read each site against your partner profile — the coaching blogs, macro-tracking sites, and home-gym reviewers no marketplace has indexed.
The network directory shows the sliver that applied. The vertical spans strength coaches, running blogs, macro and meal-prep sites, and home-gym reviewers — most never joined a program. The figures below are estimates from our classification of the active web, labeled as such; your exact numbers come from a calibrated run.
An ICP here is a precise signal set, not a follower count. Below is a typical profile for a supplement or equipment brand recruiting content publishers — required signals that must all hold, preferred signals that lift the fit score, and disqualifiers that remove whole classes of false positive.
The same vertical pull serves several advertiser types — each starts from a template ICP and is calibrated to its program.
Protein & supplement brands Activewear & apparel Home-gym & equipment Workout & macro apps Meal-kit & nutrition DTCA gym franchise or a brand's own storefront looks "fitness-relevant" to any keyword filter — but it is a competitor or a merchant, not a publisher to recruit. Structural disqualifiers remove that class before your team ever sees it.
Beyond the shared 20-signal vocabulary, every fitness domain is read for the fields that actually decide fit here. Each is extracted from what the site publishes and shipped with a confidence score.
Need a field that isn't here — "accepts sponsored posts", "already in a fitness affiliate network", "focuses on running vs strength"? Custom signals are defined per engagement and calibrated the same way.
Fitness & nutrition looks easy to target and isn't: the loudest accounts are already saturated, and the same terms describe coaches, gyms, and storefronts. A census that reads intent surfaces the partners your competitors never see.
Every protein and apparel brand is already in the same big creators' inboxes. Margin lives in the niche coaching and meal-prep sites that never joined a network.
A franchise page or a supplement storefront reads "fitness-relevant" to keyword filters. Own-commerce and franchise disqualifiers strip them out structurally.
A single-discipline coach converts an on-topic audience better than a broad lifestyle page. Fit, not follower count, is what the screening ranks on.
A representative shape of a fitness & nutrition run. Every figure below is an estimate for illustration — your real universe and yield are measured on a calibrated sample before any full run.
In a large-scale production run on our own classification platform, the same pipeline processed an entire vertical end to end. The client reviewed a sample of the output against their own judgment. These are actual engagement numbers — not the fitness estimates above.
Networks and directories index the publishers that opted in. We classify the entire active web and read it against your exact ICP — then re-run on any subset when your definition sharpens.
| Question | Marketplace / network directory | Full-web census |
|---|---|---|
| Who is in the pool? | Fitness publishers who joined the network | Every fitness-adjacent active domain, opted-in or not |
| The niche coaching blog with no network account | Absent | Read, classified, scored — the un-poached long tail |
| The brand's own storefront posing as a blog | Present, wrongly | Zeroed on the own-commerce signal |
| Gym franchise in publisher clothing | Present until a human checks | Classified out as a competitor, documented |
| Why is this site a fit? | It appeared in a category | Per-signal values and a confidence score for every row |
| Your ICP changes mid-search | Start filtering again | The universe re-runs against the new signal set |
