Website performance

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

Thank you
