the Live Events is a nice method that have a great potential since not many use it yet... let me explain how you can improve your performance
1. first you must be aware that YouTube may show #1 page ranking for your events as you the event owner with the login session and IP/cookie sine you set it and visit the watch page, it will even show on google #1 page
you must have the ability to check from remote location to see the exact 'real' position from other locations...
2. know that the search volume on youtube is not the same as the search volume on google of a kw, so it's hard to tell based on google kw tool estimations, but if you got ranked high on google you will be able to see the actual traffic in real time on your google analytics (each 'waiting' will count under the 60 min and 48 hours real-time stats)
3. to get clicks on your money-site (and you can get 100's per day if you succeed) you must choose a trending subject, that many will look for ON YouTube and trick users to click your link, MUST use a thumbnail that will have a call to action that will make sense to the visitors, as some kw are more likely to be searched on google less likely to be searched for a video result on YouTube (for example "HOW TO" Niche is better with video results)
for example "leaked Sex tape of ...... " and on the thumbnail add a message that "YouTube blocked the content in your country..... click the link below.. bla bla bla "
well this is pure spam but that is the way to use an aggressive approach
on the recent world cup i generated 1000's of daily clicks as i target the main game event (without streaming the real game) i promoted some world cup CPA offers
4. note that if you want boost your event just send real waiting users it will boost the ranking instantly
