Description of the Problem
To learn more about delivery efficiency, click the "Investigate in delivery center" link on the Delivery Efficiency Over Time chart.

In this example, this chart shows an increase in the number of pages not cached as the reason for the decrease in delivery efficiency.
Possible Solutions
To address this problem, you need to investigate why SpeedWorkers cannot cache all of the pages requested by bots. First, determine if the pages were in the inventory for the selected period using one of the following methods:

Use the following filter in the SpeedWorkers URL Explorer:
If the pages were in the inventory:
If pages in the inventory cannot be refreshed, the Refresh Efficiency will also decrease. See the SpeedWorkers Use Case: Low Refresh Efficiency article for more information.
If the pages were not in the inventory:
Use the "Top Non-Delivered Pages (Not Cached) to Google by Behavior" Explorer bookmark in the SpeedWorkers URL Explorer to locate pages frequently requested by Google but not in the inventory.
Add other input sources to your inventory settings one at a time, evaluating the impact after adding each source. The goal is to know about >90% of the pages requested by bots, not to include every page of your site.
