I'm wondering if someone can explain to me the difference between unique visitors as calculated by webalizer vs those calculated by awstats.

Both programs are reading from the same logs.

On 3 different sites, I'm getting these numbers on average daily visits

awstats/webalizer

259/353

470/825

551/766

These are all wordpress sites, if that matters.

For webalizer I'm using the yellow "visits" number. For awstats I'm using the yellow "visits" number also.

Which of these numbers is the right one in terms of eyeballs on my sites each day?
