Question

I installed the google analytics js code in my site, but the Site Speed report everytime is 0%, dont show me the reality. I saw google help about this in About Site Speed but how we can see, dont work.

Anyone know which can be?

Answer 1

By default, Google Analytics only tracks the speed of 1% of all page views. This sample rate might be lower as only Chrome and Firefox are supported. You can increase the sample rate with a custom setting:

sampleRate: Value between 0 – 100 to define the percentage of visitors to your site that will be measured for Site Speed purposes. For example, a value of 5 sets the Site Speed collection sample to 5%.

Async Snippet (recommended)

_gaq.push(['_setSiteSpeedSampleRate', 5]);
_gaq.push(['_trackPageview']);

Traditional (ga.js) Snippet

pageTracker._setSiteSpeedSampleRate(5);
pageTracker._trackPageview();
