Specyfikacja reklamy natywnej

A native ad spec is the set of technical and editorial requirements a native ad network imposes on a creative so it renders correctly inside publisher feeds and recommendation widgets. Specs typically define the image dimensions and aspect ratio (commonly 1200x800 or 1.5:1), maximum file size and accepted formats (JPG, PNG, sometimes MP4), headline and description character limits, the brand or advertiser name field, and the destination URL.

Why it matters#

Unlike fixed-size display banners, native creatives are reassembled by each publisher's template, so the spec governs the raw assets rather than a finished unit. Headlines that exceed the limit get truncated, and off-ratio images get cropped unpredictably across placements. Following the spec is what lets one creative adapt cleanly to thousands of sites.

Each network publishes its own spec: Taboola, Outbrain, and MGID all differ slightly on image ratios and copy limits, which is why a creative built for one network often needs reformatting for another. Spec compliance also affects approval speed and which placements a creative is eligible to serve on.

For competitive research, knowing the spec helps you reverse-engineer a rival's ad creative: the dimensions and headline length you observe tell you which network and template a captured ad was built for. See our native advertising guide for format examples.
