Why are there more Ad requests than Play requests?

Symptom: 

More Ad requests than Play requests

Cause: 

1. Ad request setting is set to ‘onload’ so every time the player loads on the page an ad request is sent. This is also known as prefetching.  
2. If this is happening more on a particular browser it could be that the browser is blocking the autoplay, so the play request is blocked but the ad request is still sent.

Impact:

Medium high - these ad requests without a play request are fake ad opportunities and if the algorithms pick up on lots of these you could be penalised.

Resolution: 

1. Set your ad request mode to ‘onplay’ so an ad request is only sent when there is a true opportunity for an Ad to be delivered. 
2. Check that the autoplay player is muted so that the play request isn’t blocked by the browser.
