Methodology & definitions

How the data is collected

The data source is the public web. mediabuyer.site observes the same native ad widgets any visitor sees on publisher websites — the sponsored-content and recommended-for-you units served by Taboola, Outbrain, MGID, and RevContent. We record the public attributes of each creative: its headline, description, thumbnail, advertiser branding, and the destination it links to. For each destination we follow the public redirect chain to record the landing-page host.

We observe only what is publicly served. We do not access any network's dashboard, API, or account, and we report no private metrics — no spend, no impressions, no click or conversion counts. Longevity and presence are the only signals we publish, and both are derived purely from repeated public observation.

Observation window & refresh cadence

The index reflects a rolling recent observation window rather than the entire history of a creative. Within that window, longevity signals such as days-active are computed; a creative that stops appearing eventually ages out of the active set. This keeps the surface focused on what is running now, which is what a media buyer needs.

Crawls run on a daily cadence. New creatives observed in the latest crawl appear on the live feed after the next build, and each surfaced page carries a visible last-updated date so both readers and AI engines can judge recency.

Definitions

The terms below are used consistently across every surface on mediabuyer.site. Each definition is self-contained.

Creative

A single native ad unit — its headline, description copy, thumbnail image, advertiser branding, and destination link — as served inside a content-recommendation widget on a publisher's website. Each creative has its own detail page on mediabuyer.site.

Seen

A creative is 'seen' on a given date when mediabuyer.site observed it live in a native ad widget during that day's public-web crawl. Seen is an observation, not a measure of spend, impressions, or clicks — those figures are private to the advertiser and the network and are never claimed here.

First seen

The earliest date within the observation window on which mediabuyer.site observed a creative running. It marks when the creative entered our index, which may be later than when the advertiser first launched it.

Last seen

The most recent date on which mediabuyer.site observed a creative still running. A recent last-seen date suggests the creative is currently active; an older one suggests the advertiser has paused or retired it.

Days active

The number of distinct days within the rolling observation window on which a creative was seen. Days-active is a longevity signal: a creative an advertiser keeps running for many days is one they are likely making money on, because losing creatives get cut quickly.

Winner

A creative that has been seen on nearly every day of the observation window and validated across more than one country. Sustained, multi-market longevity is the strongest public signal that a creative is profitable, since unprofitable creatives are paused long before they reach that longevity.

Mover

An advertiser or creative whose observed presence changed sharply between recent crawls — for example, a creative newly seen across many countries, or an advertiser that expanded its set of running creatives. Movers surface fresh activity rather than long-running staples.

Advertiser

The brand name attached to a creative, as supplied by the native ad network's own branding text. The advertiser is who is paying to run the ad. It is read from the network's labelling, not inferred from the destination domain, so the same advertiser may appear under slightly different display names across networks.

Landing-page host

The hostname of the page a creative sends a clicker to, after all redirects have been followed. Grouping creatives by landing-page host shows which destinations an advertiser or vertical is driving traffic to. Tracker and cloaker hosts are excluded from standalone host pages.

Vertical

The product category a creative promotes — for example health and supplements, finance, or survival and preparedness. The vertical is a classification of the offer, used to browse creatives by the kind of product being sold.

Network

A native ad network is a content-recommendation marketplace that places sponsored articles and product cards alongside editorial content on publisher websites. mediabuyer.site covers Taboola, Outbrain, MGID, and RevContent. A native ad network is distinct from an affiliate network, which recruits affiliates and pays commissions, and from a tracking platform such as Voluum or Everflow, which records the click and conversion.

Privacy: no personal data collected

The corpus is about advertisements, not people. We collect no personal information about the individuals who appear in or interact with the ads we index, and the records carry no personal data. Browsing mediabuyer.site requires no login and no account. Our handling of site-visitor data, cookies, and advertising consent is described in the privacy policy and cookie policy.

Creatives shown for research & commentary

Ad creatives — headlines, copy, and thumbnail images — remain the property of their respective advertisers and are reproduced here for competitive research, reporting, and commentary. mediabuyer.site is an independent tool and is not affiliated with, endorsed by, or sponsored by Taboola, Outbrain, MGID, RevContent, or any advertiser or network it covers. All trademarks belong to their respective owners. See our terms for the full statement.
