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.
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.
