Merchant Benefits

Whether it’s in line or online, nobody likes to wait. Website visitors have developed an expectation that websites will load quickly, and if not they will move on. A number of studies have found that the impact of slow loading pages is significant, especially for transactional Web sites:

A 2009 Forrester study found that 47% of visitors expect a Web page to load in 2 seconds or less, and 40% will abandon if it takes more than 3 seconds.  Furthermore consumers have begun associating load times with their perception of a brand’s credibility and quality.  According to the same study, 27% of consumers say that visiting a slow site makes them more likely to visit a competitor!

• Google found that a 500ms slowdown equals 20% decrease in ad revenue.
• Microsoft Bing found that a 2-second slowdown means a 2.5% decrease in queries and overall clicks.
• Amazon finds a 100ms slowdown - one tenth of a second! - can mean a 1% decrease in revenue.
• Yahoo! found that a 400ms improvement in load time translated to a 9% increase in traffic.
• Mozilla mapped a 2.2s improvement to 60 million additional Firefox downloads.

So you have to optimize your site for speed.
