Outbrain is one of the major content-recommendation native ad networks tracked on mediabuyer.site. Outbrain is the other half of the tier-one native duopoly, historically more selective about advertisers and skewed toward premium publisher inventory. This page lists the advertisers currently most active on Outbrain, grouped into three activity bands — "most active", "very active", and "active" — based on how many distinct creatives each one has running. Bands are relative within this network: a "most active" advertiser on a smaller second-tier network might still buy less inventory than a "very active" advertiser on Taboola. Click any advertiser to open their page, which lists every native creative they currently run, the network split, country footprint, and the LP hosts they use. The list refreshes daily from the live spy crawl.
The three bands — most active, very active, active — are relative within Outbrain. An advertiser in the "most active" band has at least half as many indexed creatives as the single most active advertiser on this network; "very active" has at least a fifth; everyone below sits in "active". The bands are useful because they normalize across networks of very different sizes without surfacing raw counts that would invite misleading comparisons.
If you're looking for the next breakout buyer, watch the "active" band: most advertisers who scale into "most active" passed through it in the previous week or two. If you're looking for established workhorses to reverse-engineer, the "most active" band is where they sit.
Click any advertiser to open their page. There you can see every creative they currently run across all networks (not just Outbrain), their country footprint, the LP hosts they push traffic to, and the vertical distribution of their creatives. That cross-network view is the fastest way to identify a buyer who is winning on Outbrain and decide whether to study them or compete against them.
The /networks/outbrain parent page lists every creative running on Outbrain regardless of advertiser, sorted by recency — useful for spotting fresh angles independently of who is buying.
