hey,,,
i am have a project to do a web Statistics website like Alexa ;
what i need is a way to get all needed information to save it in my db ;
i will use PHP with javascript to implement this ;
what data i want to retrieve :
1- number of unique users
2- page referrer
3- user`s country
4- how much time user still in page
and as u suggest if there are anymore Statistics options available
something like this http://www.nltechno.com/awstats/awstats.pl?config=destailleur.fr
i need also a way to implement charts and reporting classes
Is it may make some problems with Search engines or it will safe and have not a problem with crawlers
thanks
