Why website performance matters?

Website load speed influence on business


What is website performance?

It is how quickly your visitors

will get your information


If your site is slow...

...less visitors will reach your

product


What is a slow site?* Visitors analysis:

47% expect a web page to load in two seconds or

less

40% will abandon a web page if it takes more than

three seconds to load

52% of online shoppers claim that quick page loads

are important for their loyalty to a site

* According to Akamai study: http://www.akamai.com/html/about/press/releases/2009/press_091409.html


So if a user visits a slow site...

14% will start shopping at a different site if page

loads are slow, 23% will stop shopping or even

walk away from their computer.

64% of shoppers who are dissatisfied with their site

visit will go somewhere else to shop next time.

* According to Akamai study: http://www.akamai.com/html/about/press/releases/2009/press_091409.html


Microsoft research on server side delays:

Delays above 200ms introduce strong negative impacts on the following metrics:

Repeat usage

Revenue (A revenue drop per user as much as 4%)

User engagement

Customer satisfaction

Time to first click

Google concluded...

... that a linear relationship exists

between increasing server side delays

and user satisfaction metrics,

abandonment and declining repeat

searches


So if you have a slow site...

...you are wasting money


What can you do to improve performance?

Measure your website performance

Set high website speed as one of your

development goals

Adopt new technologies (Cloud hostings,

CDNs, Distributed storages...)


When you build a new feature or a website

First make it work and then make it fast

Implement, measure and make it faster

Make it smaller but faster

Optimize your features as well as your

platform


Serve all your users

You will need to scale one day

So plan for scale and be prepared to

handle it once required
