For those of you looking for some Google AdWords advice on metrics and account optimization, today is your lucky day.
Google is hosting a live Google Hangout named AdWords Office Hours: Metrics that Matter today at 2pm EDT.
This is where you can ask a live Googler questions about your campaigns.
It is best to submit your questions beforehand via Google Moderator just in case you do not get into the hangout. Google will also stream the hangout live and then archive it for viewing later on the +GoogleAds Google+ page.
During this Hangout, a Googler from the North American AdWords support team will answer live and submitted questions related to AdWords metrics and account optimization.
To join the Hangout, look out for the event at 11 AM PDT on Wednesday and click the 'Join Hangout' link on the +GoogleAds page at that time. If you're not able to join the session, we'll post answers to your questions, as well as any live questions, on the Moderator page.
