Perhaps it is a very basic question, but how can I differentiate them without using tracking gifs with javascript or known robots lists?

I don't know if there is any parameter that can be considered related to a human visit other than the user agent. It is impossible to keep an up to date listing of browsers ua or robots ua (search engine bots, site downloaders, email harvesters, etc.).

Is here any trick to recognize the human visits? Perhaps calculating the time spent on a page?

Any input will help

Thanks,

Enrique
