Creative Specs & Approval

Every campaign needs at least one creative attached to a line item. Phase 1 of Advero supports static IMAGE creatives only; HTML5 and video are planned for a later phase.

Accepted format

JPG, PNG, or GIF (static, non-animated GIF only for now). The creative's pixel dimensions must match the placement's declared size exactly — a placement sized 728×90 will reject a 300×250 upload.

File size

Keep creatives under 500 KB where possible; oversized banners slow down the page they are served on and hurt the publisher's site performance.

Click URL

Each creative has a destination click URL. It must use HTTPS and point to a real, working page — Advero may reject a creative whose click URL is broken or misleading, per the Terms of Service.

Review

Creatives are validated automatically on upload (dimensions, file type, file size) before a campaign can start. See the Advertiser Guide for where creative upload fits in the booking flow.
