Week 2: Optimize Video Watch Pages
Back in 2009, the YouTube Help Center explained how videos are ranked in the YouTube Search results:
After determining the content of the video using our spidering technology, YouTube combines sophisticated text-matching techniques to find videos that are both important and relevant to your search. Our technology examines dozens of aspects of the video's content (including number of hits and rating) to determine if it's a good match for your query.
But, at some point in 2010, that page was removed. That was also about the time that YouTube added Upload Date to its list of ways to sort search results, joining Relevance (the default setting), View Count, and Rating. In addition, a New button started appearing next to videos that had been uploaded within the past week.
