At the same token, you seem to see a lot of video results for the BIG national and competitive KWs, compared to Local KWs. I believe this is due to G+ (Google places) eagerly displaying results for its top 7 Places local results. Therefore, automatically forcing any video results to the bottom of the page, i.e. if you have managed to rank your video for the particular Local KW (don't get me wrong there are videos that outrank Google's 7 Places results in rare cases, but even then it seems very rare).
So, if anyone would care to share their insight on this, it would be incredibly helpful to myself and to others as well.
And do not just tell us, "it's possible to rank videos". "anything" is possible ..... I am interested to know as to "why" video results are not ubiquitous in the SERPs for Local KWs? Is there anything in Googles algorithm that automatically makes it super hard for videos to rank in Local results, and perhaps the reason why it might require to rank a video in local, hence making video seo for local KWs obsolete?
