YouTube has updated YouTube Insight, a free tool that lets anyone with a YouTube account view detailed statistics about the videos that they upload to the site.

Included in the update:

One is a new demographics tab that displays view count information broken down by age group (such as ages 18-24), gender, or a combination of the two, to help you get a better understanding of the makeup of your YouTube audience. We show you general information about your viewers in anonymous and aggregate form, based on the birth date and gender information that users share with us when they create YouTube accounts. This means that individual users can’t be personally identified.

Insight now also displays statistics based on the combined total views of all the videos you’ve uploaded. Just as you can explore the view counts and popularity of individual videos, with this feature you can see your account’s total number of views, and your relative popularity on YouTube compared to other users, based on geographic location.

Uploaders can see how often their videos are viewed in different geographic regions, as well as how popular they are relative to all videos in that market over a given period of time. You can also delve deeper into the lifecycle of your videos, like how long it takes for a video to become popular, and what happens to video views as popularity peaks.

YouTube expects the new service to help video creators get more views:

Using these metrics, you can increase your videos’ view counts and improve your popularity on the site. For instance, you might learn that your videos are most popular on Wednesdays, that you have a huge following in Spain, or that new videos that play off previous content become more popular more quickly. With this information, you can concentrate on creating compelling new content that appeals to your target audiences, and post these videos on days you know these viewers are on the site. (Maybe even post your next video in Spanish?) And for those of you who are also partners, the more popular a video is, the more advertising revenue it can generate.

We’ll be making new features and additional information available fairly quickly — like a specific breakdown of how viewers discovered the video — so keep an eye out as we roll out new features. As for now, you can find currently available metrics by clicking under the “About this Video” button under “My account > Videos, Favorites, Playlists > Manage my Videos.”
