At Google, we’re passionate about speed and making the web faster, and we’re glad to see that many website owners share the same idea. A faster web is better for both users and businesses. A slow-loading landing page not only impacts your conversion rate, but can also impact AdWords Landing Page Quality and ranking in Google search.

To improve the performance of your pages, you first need to measure and diagnose the speed of a page, which can be a difficult task. Furthermore, even with page speed measurements, it’s critical to look at page speed in the context of other web analytics data.

Therefore, we are thrilled to announce the availability of the Site Speed report in Google Analytics. With the Site Speed report you can measure the page load time across your site right within your Google Analytics account.

Uses for the Site Speed report

With the Site Speed report, not only will you be able to monitor the speed of your pages, you can also analyze it along with other analytics data, such as:

Setting up the Site Speed report

For now, page speed measurement is turned off by default, so you’ll only see 0s in the Site Speed report until you’ve enabled it. To start measuring site speed, you need to make a small change to your Analytics tracking code. We have detailed instructions in the Site Speed article in the Analytics Help Center. Once you’ve updated your tracking code, a small sample of pageviews will be used to calculate the page load time.

Bringing the Site Speed report into Google Analytics is an important step of the Make the Web Faster effort, and we look forward to your feedback on Site Speed.
