Page Speed Analytics: How to Improve Web Page Load Time – Part I


Web page speed optimization has become one of the most important components of the website optimization process. Google incorporates web page load time as one of the factors for organic rankings. Web Analysts should also include page speed KPIs in analytics reports and review the changes atleast twice a month.

Page speed is the time it takes to load a web page. Google recently introduced a Google web master plugin called page speed, which essentially provides you a score for your website page speed. There are several other tools that are available to perform detail load time analysis on your website.

Most web analytics and web tracking javascript tags increase the page load time and provide bad user experience. There are several ways you can improve your page load time, and we will discuss these in the part II of this post.

First, let’s talk about how to measure your website page speed metric and establish a benchmark for future comparison.

Google Page Speed – Google Page Speed evaluates the load time performance of a web page. With page speed, you can identify the slow loading pages and make necessary changes to it to improve website performance. Page Speed is available in two formats –

a. Page Speed browser plugin – This plugin is available for both Mozilla Firefox and Google Chrome browser. The installation is similar to installing any browser plugin.

You will need to install Firebug to run the Page Speed browser plugin. Once both Firebug and Page Speed plugins are installed you can run Page Speed using the following steps in Firefox –

1. Open your website in Firefox.

2. Click the bug icon on the bottom right hand footer of Firefox.


3. Click “Page Speed” on the Firebug navigation menu and then click “Analyze Performance”
