Add an administrator HTML or JavaScript creative

Where: Advertise → Administration → Free admin ad → code creative

Code executes directly in the board page, with administrator trust. It is not a hostile-script sandbox. Ordinary advertisers cannot submit JavaScript through this administrator-only path.

Steps

1. Use a trusted provider snippet for a single placement. Retain the original snippet privately.
2. Enter desktop code and optionally mobile code; check its declared display dimensions against the placement.
3. Include the provider script tags as supplied. Save without weakening the board CSP to silence an unexplained error.
4. Open an eligible public page to execute the creative; the administration preview deliberately does not execute it.
5. Test mobile load, console errors, overflow and provider restrictions.

Check the result

The creative renders within the intended placement. Provider-controlled clicks are not automatically equivalent to addon click analytics.

If it does not work

Oversized declared native dimensions are refused using the bounded placement tolerance. Responsive/retina creatives must declare their intended display size. Delayed document.write patterns are unsupported.
