Advertiser ID
The numeric or string identifier a network assigns to an advertiser account.
Advertiser ID is the unique key a native network assigns each advertiser account (e.g. Taboola's advertiserId, Outbrain's marketerId). It surfaces in the ad-tracking URL of every click. Spy tools that scrape correctly can roll all the creatives from one advertiser into a single hub — that's the foundation of competitive intel.
Example
mediabuyer.site advertiser hub keys off Taboola advertiserId — one ID can have 400+ active creatives across 12 campaigns.
