Load GPT from recommended host
Stay organized with collections

Overview
This audit ensures that the Google Publisher Tag (GPT) library is being loaded
from the recommended host. The browser must open a connection to each new host
your page references, which can take significant time. By loading GPT from the
recommended host you ensure that all ad serving requests are made to a single
domain, reducing the number of connections to open and improving page load
performance.
Recommendations
Ensure that GPT is being loaded from securepubads.g.doubleclick.net
. For
example:
<script async src="https://securepubads.g.doubleclick.net/tag/js/gpt.js"></script>
