Overview
The time it takes for the first ad request to be made. This is the interval from
tag load until the first ad request is issued.
Recommendations
This metric is not indicative of a specific issue. It should be used to help
identify areas for improvement and track that improvement over time.
The goal here is to reduce the time it takes for the first ad request to be
made. Ensuring that other, more specific audits are passing should have a major
impact on this metric. In particular, the following audits are likely to affect
this time:
This metric identifies "first ad request" as the earliest recorded request to
one of:

Reducing this time is the primary goal, and it is achievable by improving related audits. Key actions include optimizing the ad request waterfall, avoiding bottleneck requests, preventing long tasks that block ad requests, not waiting on load events, loading GPT and bids in parallel, and parallelizing bid requests. The first ad request is the earliest recorded request to specific hosts and paths for AdSense and Google Publisher Tag libraries.\n"]]
