I’m sure you’ve heard on at least one occasion that content delivery networks are awesome. They significantly improve the speed at which your website can deliver content. Not only does that make for a better user experience, there’s also mounting evidence that faster-loading pages tend to rank higher than those that load slowly (though not, perhaps, for the reasons that you might think).

Video sharing sites pose a particular set of problems for search engine optimization. Google’s crawlers can’t interpret video content and so rely on the textual content and markup that surrounds the videos to get an idea of the terms for which videos should be ranked.
