The first thing you should do (if not done already) is analyze your current traffic. You have to make sure a good percentage of your visitors are actually sticking around to either watch the video or at least enough to look at your other content.

If this is not the case, then improving targeting for your ads might be your best bet. It is not just the quantity of the visitors but the quality that makes them worth it.

100,000 visitors that just bounce off immediately after arriving are worth less than 5,000 visitors that actually stay for the intended purpose.

A visitor that is on your site for a minute is much more likely to see an affiliate link and/or ad than one that just exits after a few seconds.

The next point would be looking at your site performance and formatting. If the site is slow to load, then people are more likely to exit as fast as they came in. Also, if they are there to watch a video clip and all the page is filled with ads everywhere, it does no good to the user experience.

Finally, make sure the ads shown on the pages are either relevant to the content in question or relevant to the customer.

Good Luck and let me know if you have any questions!
