Google has announced a new tool for optimizing, which allow you to optimize your site’s content: browser-size analysis, which is part of the In-Page Analytics report. The company created a visualization that lets you quickly determine which portions of your page are visible to which percentages of visitors.
What you have to do now is to simply navigate to the Content section in Google Analytics, and click In-Page Analytics. A new information layer is available. Click Browser Size to shade portions of the page that are below the fold. You can now click anywhere on the screen to see what percentage of visitors can see it, or control the threshold percentage by using the slider. The new feature will roll out the feature over the next few weeks.
