Embed Builder
<script async src="https://shrd.co/embed/loader.js?id=cmo8v9qk0000004l5jel6vqps&view=card&click=overlay&w=640&h=360&overlay=title%2Cdescription%2Cauthor%2CitemCount%2Cdate"></script>
One tag, no wrapper. Survives WordPress, Squarespace, Wix, Webflow — any CMS that allows a <script> tag.
The script inserts an <iframe> at its own location. Updates to the teaser design ship instantly to every embed without you touching this code.
Shrd creatives can be trafficked as standard display line items. The catch: GAM defaults to SafeFrame, which sandboxes creatives from the publisher’s page. An overlay opened from inside that sandbox renders in the ad slot, not over the page — not useful.
When a shrd creative is clicked inside a SafeFrame, it posts a message to window.top. The companion listens and opens the overlay on your page.
<script async src="https://shrd.co/embed/companion.js"></script>Drop it in your <head> or layout template. One-time install — lights up overlay behavior for every shrd creative on your site, through every ad network.
Without the companion, creatives in SafeFrame fall back to open-in-new-tab automatically. Never looks broken, just loses the overlay polish.
