According to a post in ConversionRuler Video advertising increases site conversion rates.

Can video increase your conversion rate?  Andrew Johnson’s Web Publishing Blog has an interview with Brendon Sinclair about a website he made that is just a video case study that promotes Aaron Wall’s SEO Book.  What’s interesting is that Brendon also has a normal site promoting the book, but the video site gets four times the conversion rate.

I looked at both sites and and the layout and pretty much everything else is different.  I don’t think I’d put it all on the Flash Video.   The only thing the two sites have in common is they are selling the same product…and that’s it.

I don’t like flat out comparisons like this because they’re misleading.
