Online users have hardly tolerate websites that take ages to load. Here is a list of page speed tools that webmasters and developers can use to measure website and blog load speeds.

The modern Web user is a very impatient breed. The staggering improvements in Web-based technology have raised people's expectations when it comes to loading speeds of typical Web pages. Online users have become accustomed to lightning-fast loading pages and apps, and will hardly tolerate a website that takes ages to load.

In fact, a small decrease in the page load speed, particularly on e-commerce sites, has been found to result in a dramatic increase in page bounce rates and a large decline in conversion rates. Shopping cart abandonment rates can run as high as 70 percent, with slow load times singled out as the No. 1 culprit. The problem is even worse for mobile devices, where abandonment rates can go as high as 97 percent.

The load times of your website not only affect your conversion rates, but also has a direct impact on your Google rank as well. Google made an announcement back in 2010 in which it outlined how the load speeds of websites and blogs affect Google rank. The search giant says that fast load speeds provide a good user experience, which is good for your business (and Google's as well). Google has provided various free tools that you can use to measure the performance of your Web pages as well as tools to help you diagnose the causes for slow load times and their solutions.
