@kazhkaz Good Point. I am sure that the G's ranking algorithm and YouTube's ranking algoritm fit the same purpose meaning that the most "relevant" videos/pages show up for a particular keyword search query.
If you think of a YouTube video page like any other webpage it has a title tag (title of the video), a body of text (description box) and meta tags (video tags). These have to play a big part in the way YT ranks videos. As for the importance of backlinks in YT ranking, I am not so sure. It may help the video show up on a Google search but I am not sure about a YT search.
I think the amount of time users spend watching the video helps YT assess a videos relevance for any given keyword and they adjust the rankings to suit.
Point is no search algorithm is perfect. What I think is relevant for a keyword may differ from the next person's idea.
All I would want from a tool like I mentioned originally was some data such as no. of backlinks, keyword in title or not,
keyword density in description, keyword in video/channel tags or not.
Also stuff like how many times it has been favourited, liked/disliked & shared on Facebook/Twitter/bookmark site?
How many times it has been embedded and where?
How many comments it has?
When it was uploaded?
Amount of subscribers channel has?
Playlist additions, if any?
And all the "Significant discovery events" and "Audiences" info that can be found when you access the drop down menu under the video.
If you had a tool that could do all this then an IM could use this to anlayse his comp for a whole host of keywords and after time the user will have a better understanding of how videos get ranked on youtube.
Would be nice if the top 10 results were listed in the manner in which Traffic Travis lists webpages after they have been analysed.
