We know that what users see above the fold is a significant factor in determining conversion rates. As the Google Analytics blog points out, “if visitors have to scroll to see an ‘add to cart’ button, or some other critical element, they may never get around to it.”
How it works
In comes Browser Size analysis. Its purpose is to provide a “visualization that lets you quickly determine which portions of your page are visible to which percentages of visitors.” To use it, navigate to the Content section in Google Analytics and click In-Page Analytics (if you don’t see it, just wait – the feature is rolling out gradually over the next few weeks).
Clicking on Browser Size shades portions of the page that are below the fold, and you can click anywhere on the screen to see what percentage of visitors can see it.
The Show Percentiles feature allows you to see a summary visualization of several different percentiles. According to Google:
This helps you understand how browser sizes are distributed–for example, if you choose to compare All Visitors with the Mobile traffic segment, you should see a substantial difference. You can also use this technique to compare different pages on your site. For example, if users on your goal page appear to have larger browsers than those on your landing page, this is a strong indicator that you are losing conversions because some pages in the funnel are not laid out in an optimal manner.
By default, the report shows you data based on the current page you are viewing. You can use the picker to also view data for “visitors to the site” or “Web users” so you can compare it to different benchmarks.
If this all sounds familiar, you might have been using an earlier version of this tool called Browser Size over at Google Labs. Now that the lab has succeeded, the Browser Size tool as part of In-Page Analytics offers a more powerful set of features. So, the previous test version will be sunsetting in about a month.
