Hi everybody,

thanks for reading this post.

Here is an example of basic tracking.

I used javascript and some php.

If you click on the link below (please be aware that is just a rough page!!! don’t expect a web designer work for this ) you will be redirected on a page where the basic of tracking is shown.

Actually you will be given information about the browser that you are using (even though this info is not 100% accurate – but one of the javascript object.property is quite accurate: navigator.userAgent), then you will be given your IP address (which most of the times helps in understanding your location or nearby you – e.g. this would be extremely helpful for geo-targeting, even though other data could be used), and again couple of “unique” IDs will be set up on the fly for you. One of these IDs is built in javascript (gathering info from your machine) and the other one is coded in php (using the information on the server).

At a first impact these 2 IDs would seem useless (because these IDs continuosly change each time that anyone refresh or access that page), but actually if these IDs are linked and triggered with a rare event on the website, they can be extremely useful for additional purposes.

On the top of it, a detection about your cookies is also done (just checking if your cookies are on or not).

PS Make sure javascript in your browser is enabled, otherwise you will get a message suggesting you to enable javascript in your browser (don’t worry, no data collection is done in this case).

In one of the future posts, I will also set up cookies (which is fundamental for any kinds of proper tracking). For now (if you want to have a look at how cookies are set up and work), please feel free to check it here: this is a basic example of using javascript and if you complete the quiz and then access this page again, you will understand how the cookie works. Feel free to have a look atthe code as it is fully commented.
