Discourse is a Single Page Application and all the page markup is create client-side via our EmberJS application.

Using direct DOM manipulation like `document.write` is in direct conflict with the whole thing and has a really low change of “just working”.

I’d recommend trying to adapt you ads system to use our [House Ads in the official Ad Plugin](https://meta.discourse.org/t/house-ads-in-the-official-ad-plugin/116715) system. Maybe you can have a single ad in the house ads inventory, and use the [page change hook](https://meta.discourse.org/t/developer-s-guide-to-discourse-themes/93648#heading--4-c-11) to contact the ad server and replace the ad with the response? Or maybe your ad system can write to the House Ads inventory directly via API?
