Native
Our Native Ads are integrated into premium publisher environments across a variety of placements. Because they adapt to each site's design and layout, their appearance can vary between publishers and placements. This format is well suited to driving relevant traffic to your website.
Product discovery
Gallery-style format for showcasing multiple products or features, delivered in responsive templates or IAB standard sizes
This page is the working reference for creative delivery: every accepted size, weight, file type and duration across the C Wire format range. The table below is the complete acceptance list.
Every unit meets the LEAN standard: light files, no expansion unless the reader asks for it, and nothing covering the article.
Maximum weights are hard limits measured at delivery, not at upload.
Video runs in-stream and out-stream at Standard and Impact, including vertical.
Impact units are supplied with page integration in mind: the safe area, expansion behaviour and close control are part of the acceptance check.
Specifications are listed per variant, because one format can accept more than one shape. Where a unit is defined by ratio rather than fixed pixels, the ratio is given. File types are the complete accepted set for that variant; anything else is rejected at upload.
Questions
Standard IAB sizes as image or HTML5, within the published weight limits, plus a click-through URL and any third-party tracking. Standard units render in the slot the layout already has, so no publisher integration is needed.
An MP4 in the published resolutions and durations, or a VAST tag. For MatchPersona for YouTube the creative is hosted on your YouTube channel, public or unlisted, and C Wire activates it from there.
The assets listed per format on this page: logo, headline, description, images or video, and a call to action. C Wire builds the unit, you approve the render before it runs. Impact units run where publishers are contracted directly.
C Wire's ad ops team reviews every unit against the LEAN weight ceiling and the non-overlay rule before it is accepted. Send the files to your C Wire contact and we confirm approval.
