Outbrain ad spy tool
Outbrain is one of the two largest content-recommendation native ad networks on the open web, alongside Taboola. Mediabuyer.site is a free, no-login spy surface that indexes live Outbrain creatives across the EU-heavy publisher footprint where Outbrain has historically been strongest.
Every Outbrain creative links to its landing page with the original click parameters intact, names the advertiser as branded on the creative, and stamps the country footprint and date range. The corpus skews toward DE/AT/CH/FR — the European publisher base — so an affiliate running campaigns in those geos will find Outbrain coverage particularly relevant.
Browsing surfaces let a researcher pivot the data three ways: per-creative (the canonical detail page), per-advertiser (every creative an advertiser is running across networks), and per-host (every advertiser pointing to a given landing-page domain). The data dictionary at /data-dictionary documents every field.

Frequently asked questions
- Is mediabuyer.site really free?
- Yes. The browsing surface — every creative, every advertiser hub, every landing-page capture — is publicly viewable without an account. No paywall, no trial countdown, no upgrade prompt. The project is operator-built and runs on its own infrastructure.
- How fresh is the data?
- Crawls run on a daily cadence. New creatives observed in the last crawl appear on the live feed within hours of the next build. Each creative carries first-seen and last-seen timestamps so a researcher can tell whether they are looking at something that started running last week or something that has been live for months.
- Does it require a login or signup?
- No. There is no signup wall. Anyone can open a creative, see its landing page, advertiser, country footprint, and how long it has been running. Saving creatives to a personal watchlist is the only feature that asks for an account, and even that is optional.
- Which native ad networks does it cover?
- Taboola, Outbrain, MGID, and RevContent — the four major content-recommendation networks that place sponsored articles and product cards alongside editorial content on publisher sites. Coverage spans the open web (publisher-side placements), not the social platforms.
- What fields does each creative carry?
- Network, advertiser, headline, thumbnail, click-out URL (with all original parameters preserved), landing-page host, country footprint, vertical, first-seen, last-seen, days-running, longevity decile. The full reference is at /data-dictionary.
