Page Summary
This audit helps identify scripts and stylesheets that slow down the loading of ad tags by being requested before them.
Reducing the number of these resources loaded prior to ad tags can significantly improve ad loading speed.
Optimization strategies include loading ad tags earlier, inlining critical resources, using async or defer for non-critical scripts, and separating stylesheets by media query.
Supported ad tag libraries include AdSense and Google Publisher Tag, with specific script URLs for identification.
Overview
This audit identifies resources (specifically scripts and stylesheets) which are
delaying the loading of ad tag libraries. These are resources that were
requested and received before ad tag libraries began loading. Reducing the
number of resources requested prior to tag load will speed up ad loading.
Recommendations
The details of this audit contain a list of all scripts and stylesheets that are
delaying tag load. The goal is to reduce the number of entries in this list as
close to 0 as possible. Some tips for doing this include:
Loading ad tag libraries earlier in the <head> of the page.
Inlining scripts and stylesheets critical to core functionality directly into
your HTML.
Marking non-critical scripts with the async or defer attributes.
Separating styles into different files by media query and using the media
attribute to load them only when needed.
More information
The following ad tag library scripts are supported:

To improve ad loading speed, reduce the number of resources requested before tag loading. Key actions include loading ad tag libraries earlier, inlining critical scripts/stylesheets, marking non-critical scripts with `async` or `defer`, and using the `media` attribute for conditional stylesheet loading. Supported ad tag libraries include AdSense and Google Publisher Tag, each with specific script URLs. The goal is to have minimal or zero items on this list.\n"]]
