I need to try and track visitors to a specific page. Im asking here as i generally use php for my pages.

I dont want to use webtrends as its not accurate enough, i thought about maybe just a page counter that was hidden? But that only gives visitor numbers, i was thining that i might be able to get visits per day, or some more interesting, but legal information.

Basically its to track an adverts effectiveness.

Thanks for any info.
