Thats a great example of a video ad Linda.
OK I have been doing a little experimenting.
I have a site that averages ~ 2000 uniques per day.
In the centre of the home page I placed a 250 x 250 Adsense block. I was receiving ~ 60 clicks per day from that.
I removed that and replaced it with a 250 X250 Affiliate Banner. One that was relevant to the topic, I really went all out searching for a company that had an eye catching banner thatwould appeal to the visitors to the site. It also offered a free product and a cash prize...I mean who would not click on it to at least check it out.........The result.....7 clicks
Then I placed a video in the same spot......pretty crappy and not related to anything on the site......

462 people viewed that video.
I rest my case
