Marketing Loves Social

Social adds LOTS of resources -> 86 JavaScript, images and CSS.

Other things you can do

• Redirect from www to non-www using client-side– Use a 301 redirection instead of 302

• 404s – usually take longer• Run JavaScript code while your page is loading.• Only look at how fast your site is from your desktop• Think your website is fast enough• Do not test your websites performance• Think your developers would never do any of these

things

24

HUMAN FACTORS

on the business• Lack of understanding about what makes a website slow

or fast• Lack of the ability to determine if there is a problem• Lack of time to test and fix issues
