    How does Youtube determine order of results?

    When you do a Youtube search , for instance, for "pet tricks", how does Youtube decide the order of the results? Clearly it is not anything to do with date published or views. So when there are 20 pages of results, what makes the first result show up as #1?

    I believe it's primarily based on relevance (whether your search string is within the title, tags, description, etc.).

    Thanks, layer0. I figured that was the only thing left, relevance. But here's the "extended" question. Again, let's say the search query is "pet tricks". There are dozens and dozens of result pages. Hundreds of those results will have equal amount of "pet tricks" title tags, description, etc. So what makes one result end up as result #1 and another (with equal relevance) end up at result #100?

    Given that Youtube is owned by Google, can we assume that they use similar algorithms to display YT results?

    Perhaps they also look at click-through rates on various search result display orders and adjust future search results accordingly?
