Right now I'm using adcenter for one of my first campaigns, I'm getting tons of impressions a day but only around 40 clicks. My max cpc is set at .45 and my average position is around 8. Only 1 conversion so far. I changed my landing page to include a sales video that is around 20 minutes long but after checking analytics, the users are only staying for around 4 minutes. What kind of suggestions do you guys have to improve conversions? Any help is appreciated.
