Making a good video can be difficult enough; you shouldn’t have to struggle to get it in front of individuals and search engines afterwards.  So at Ad:Tech San Francisco, The Search Agency’s Drew Hubbard gave some tips on how to optimize video for search.One key point is that “it’s all about the content on the page.”  For now, content producers should still assume that videos are invisible to search engines.  Be sure to come up with good titles, good tags, and good keywords.Otherwise, if you’re trying to decide between hosting a video yourself or turning to a site like YouTube or Vimeo, there are a couple of things to take into consideration.  Going the DIY route will grant you a great deal of control over the clip.  At the same time, letting YouTube handle things may save you money, and it can put also the video in front of a larger audience.Hubbard pointed out that, according to some statistics-tracking firms, YouTube is actually competing with Yahoo for the title of number two search engine.
