I went to the TradeMe Rockstars presentation last night where TradeMe again emphasised the importance of speed. I happened across an article today which reports Google’s findings when fine tuning their search results (a report from a talk at the 2006 Web 2.0 conference). They found a half-a-second slow-down equated to an pretty incredible 20% drop in traffic. A similar experiment was conducted at Amazon where they found just a 100ms increase in load time resulted in substantial drops in revenue.

There are also some good comments left on the article including:

“IBM did studies on interactive interfaces in the 80s. The results showed that as the return time neared two seconds, the time the user spent staring at the screen increased. The curve turned up dramatically below two seconds. Below one second, someone had to pry them off the keyboard. And that was with non-rich terminal applications.”

“Research from the 80s and the PLATO Project showed that response time really needs to be about .25 second. For something where users expect a bit of work by the computer, stretching that to .4 I guess is OK. But, I would shoot for .25sec.”

Yeah.. .but the exam itself specifically references some book. Ah there it is.

“List rules 12-14 as well as the first four chapters of High Performance Web Sites Volume 2
that were made available: ”

“High Performance Web Sites Volume 2″ My guess http://www.amazon.com/High-Performance-Web-Sites-Essential/dp/0596529309/ref=sr_1_1?ie=UTF8&qid=1231999764&sr=8-1

Hi Rob,

This is an SEO report, not website optimisation (which is about making a page fast!)

I’m not claiming to even know the fundamentals – but I happened across a site which provided the best automated grading I’ve seen (http://website.grader.com). An example report for nzpost.co.nz is here: http://website.grader.com/wsgid/2163592/default.aspx. They also grade Press Releases and Twitter profiles??
