What does a Meta ads agency do?
A Meta ads agency plans the campaign structure, produces and tests the images, videos and copy, sets up the Meta Pixel and Conversions API so results are measured, builds audiences and retargeting, manages budgets and Advantage+ automation, and reports in cost per lead or return on ad spend.
On Meta the creative is the targeting: the platform decides who sees an ad largely from how people respond to it, so a steady supply of new images and videos matters more than audience settings. GrossiWeb plans a creative test each month, produces the variants with your photos and footage, and retires ads as their cost per result rises.
