# Advertiser tasks

> Every operation for managing advertisers and their sub-resources

An advertiser is the top-level account that owns campaigns, creatives, audiences, and linked partner accounts. These tasks cover the full advertiser lifecycle plus its three attached collections — linked accounts, catalogs, and audiences. For fields, lifecycle, and concepts, start with the [Advertiser overview](/v2/object-guides/advertiser).
