Getting started
Every ad space has one embed snippet, shown on its manage page:
<script async src="https://your-worker.dev/embed.js" data-space="SPACEID"></script>
Paste it directly into your page's HTML wherever you want the ad to appear — no separate <div> needed, it builds its own container next to itself. It works on any site: plain HTML, WordPress, Squarespace, anything that lets you add a script tag.
One thing that won't work: pasting the tag into a browser's DevTools "Edit as HTML" panel, or inserting it via innerHTML in your own code. Browsers deliberately refuse to execute scripts added that way — nothing will happen, and nothing will be logged, because the tag never actually ran. Add it to your page's real source instead, or insert it with document.createElement if you're doing it from your own script.
Until an advertiser is live, the slot shows a small default banner inviting people to advertise on your site — it's never just blank.
