is it possible to track your visitors individual behavior?

The short answer is "Yes, sure", but there are lot of options how to do it. I will talk now about how to track behavior using google analytics.
I guess  everyone knows how to implement google analytics at your website  - to create account at google analytics and to paste the code snippet like:

    var _gaq = _gaq || [];
    _gaq.push(['_setAccount', 'your-account-num']);
    _gaq.push(['_trackPageview']);

    (function() {
        var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
        ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
        var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
    })();

This great tool of google makes you able to analyze your website traffic (like getting reports) 

 








without writing any code!
 
The problem with tracking individual user's behavior is that you need analytics service to know the id/name of specific user. Thats where angularticks library can be usefull.
This lybrary enables you easily fire events with data you choose to send:

 var eventData = {  
  category: 'motorcycle-details',
  label: user+' viewed '+$routeParams.productname +' motorcycle'
 };
 $analytics.eventTrack('viewing-motorcycle-details', eventData);

If user name passed through the event parameres the reports will show results with his behavior:



 

how to make google to index your angular single page app

The problem with angular single page app (which uses router module) is that google crawler cannot access route view dynamic content.
When processing such pages (like mysite.com/#/product/zzr1400) google crawler sees only template with "{{something should be here}}" tags.

I have created this site for experimenting purposes.
According to little research I did (see this grate tutorial and here) for make your site to be indexed by google you need to serve crawler bot static HTML snapshots made from your dynamic views.

Steps

For doing it you need to perform following steps:
1. place following tag in the head of your index page:

<meta name="fragment" content="!">

2. make sure your router configured to use "!" or html5 mode

  $locationProvider.html5Mode(true);
  $locationProvider.hashPrefix('!');

This tells crawler to access the site using "?_escaped_fragment_=" quesry string.
3. configure your server or use some online services like Prerender.io or brombone to serve static html snapshots of your content.

How to check you pages are cached for crawler?

If you using prerender.io online service:
Access your dashboard:

You should see the table of your pages in the "cached pages" section.
