Source: https://youtube-creators.googleblog.com/2018/03/youtube-studio-better-insights-new.html YouTube is rebranding "Creator Studio" and renaming it "YouTube studio" with 3 important changes. In the next several weeks, YouTube Studio will be the default display for users, the company said in a blog post — though creators will have the option to revert to the old Creator Studio format if they so choose. The three new metrics that the Studio app will soon offer include: ‘impressions’, ‘impressions click-through rate’, and ‘unique viewers’. An impression occurs whenever a viewer sees a creator’s thumbnail on YouTube — including on the homepage, subscription feed, search, or ‘Up Next’ section, according to the company (see below). Impressions click-through rate, however, shows the percentage of impressions that turned into views. YouTube notes that optimizing titles and thumbnails can help improve this latter figure. Moving forward, you’ll see three new metrics in YouTube Analytics – Impressions, Impressions click-through rate, and Unique Viewers – that give a deeper understanding of your reach on YouTube. These new metrics are rolling out to a small group of creators today and will be available to everyone in YouTube Studio within a few weeks. A couple of weeks after that they will be available in Creator Studio Classic. Impressions An Impression is counted when a viewer on YouTube sees one of your video thumbnails. Impressions tell you the potential reach of your content on YouTube, since each impression is an opportunity to earn a view. Impressions click-through rate We’re also adding Impressions click-through rate, which shows you the percentage of your impressions on YouTube that turned into views. Different factors affect your click-through rate. For example, effective thumbnails and titles that attract your target audience may drive this rate up. This metric can help you make more informed decisions on how to optimize your titles and thumbnails, especially when you look at how this metric changes between past videos.

Whether they watch on desktop, mobile phone or watched more than one of your videos, that person will count as one unique viewer. You can use this data to compare your audience size to your subscriber base, and identify videos that helped reach a wider audience. This information can also help guide your content strategy, and showcase your true reach when discussing brand deals and sponsorships.

It's a great way to improve thumbnails IMHO. Thoughts?
