Sample HTML5 banner creatives
HTML5 banners in ZIP are the standard upload format for Google Ads, Campaign Manager 360 (DCM), DV360, Xandr and other ad servers. Each ZIP contains index.html + assets and implements the clickTag contract. Samples cover the full complexity range: from a static image with a click to CSS and vanilla JS animations, rich media with video and expandable banners with two states. Unpack and open index.html in a browser to check the rendering locally.
🧠 How an HTML5 banner works
Inside the ZIP there is always an index.html — the entry point the ad server opens in a fixed-size iframe. The <head> usually has a meta tag <meta name="ad.size" content="width=W,height=H"> for Google Ads. Clickability is implemented via clickTag: the ad server replaces the clickTag variable in the JS with a tracking URL at serve time; the JS calls window.open(clickTag). The size of the ZIP and its assets is limited by the IAB Display Creative specs (initial 200KB, polite up to 2.2MB). For production the assets usually must be self-contained inside the ZIP — external CDN links are often disallowed, except whitelisted domains.
