We've just added seven additional metrics to the 'Time-Based' and 'User Geography' reports that we pull from YouTube.
Here's a list of new fields that you now have access to:
Annotation Click Through Rate
Annotation Clickable Impressions
Annotation Close Rate
Annotation Closable Impressions
Please note that no action is required in order to obtain data for these metrics going forward, providing you've connected one of these reports to Funnel.
You can find the full list of supported YouTube fields inthis article.
We hope you find these new metrics useful! If you're unable to find the field you need or if you would like to see historic data for these metrics, please email@example.com and we'll be happy to help :)
