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.
If the slot is inside an iframe: some page builders and widget areas wrap embedded code in a sandboxed <iframe>. If that sandbox doesn't include allow-popups allow-popups-to-escape-sandbox, the browser silently refuses to open the advertiser's link when someone clicks the ad — nothing happens and no error is shown. Add those two values to the sandbox, or paste the tag directly into the page instead of into an iframe.
Ad clicks open in a new tab by default. Add data-target="_self" to the script tag if you'd rather they open in the same tab.
