Ad request waterfall
Stay organized with collections
Save and categorize content based on your preferences.
Overview
A report of the resources requested before the first ad request is made. These
resources delay the first ad request, so minimizing their number will speed up
ad loading.
Recommendations
This audit is purely informative and not something a page can pass or fail. Use
the information provided to reduce the time to first ad request by:
- Reducing the number of resources by removing them, deferring them, marking
them async, etc.
- Combining resources to reduce the number of requests.
- Optimizing the order in which resources are loaded by requesting only critical
resources prior to requesting ads.
Any of the above optimizations will have a positive impact on ad speed.
