Did you know that the traffic you get can be human made or robot made? And that is almost impossible to detect whether real people browsing your website or robots. The robots these days become very intelligent, while they are browsing your website they also provides you with all the information like IP, Location, Browser, Screen Size, Time on page etc. In that way they look like real people are browsing your website.

You should know that this information along with IP addresses are real persons, but your traffic provider is probably redirecting them to many clients with non human present.

Due to my research with three large PPC traffic sources, i found out that in most cases 90% of them have their browser canvas 1x1 pixel size which shows you that these visitors are not human. No real person can read the pages through 1 x 1 pixels browser size.

It is very good for everybody if you have some javascript programming skills or to know somebody to detect such visitors or you can just use one of the online services which provides you with this kind of information.

It is really bad if you are paying for the traffic that aren't even real persons.

If you are paying for traffic you should certainly collect this kind of information these days as you can easily prove to the traffic provider, that they are sending you non human traffic. You will also save a lot of your advertising spending.

It is very good to have only quality traffic driven to your webpage.
