Overview

Use Case: Homepage Takeover

A homepage takeover requires all homepage ad slots to render the same advertiser creative set during the booked window. Because a single GAM creative renders only once per page, you must duplicate creatives to cover every slot.

Key‑Value Targeting

Use the site-side key category with value homepage for precise homepage targeting.

Key = category
Value = homepage
GAM UI → Add Targeting → Custom Targeting → category = homepage

Example screenshot:

This shows the key-value targeting setup in GAM.

💡 Tip: To view the key-value targeting in the GAM console, open guernseypress.com/?google_force_console in your browser.
The console will appear, and you will be able to see the value as shown in the screenshot above.

Example site-side (gpt.js) injection

<script>
  // Example: set page-level key-values
  window.googletag = window.googletag || { cmd: [] };
  googletag.cmd.push(function() {
    googletag.pubads().setTargeting('category', ['homepage']);
  });
</script>
