There are a number of sites on the internet that will provide you with statistics for your site. Some are free, or offer limited stats for free, and others only offer their services for a fee.
One of the free site statistic websites that I use is StatCounter. They offer both free and paid services. The free service will keep track of the stats for your last 100 visitors. Since this site doesn’t get a lot of daily traffic yet that’s fine with me.
I can visit StatCounter and see which domains the majority of my visitors have come from, what search engines sent them and what search terms they used to find my site.
Another thing that I like at StatCounter is that it keeps track of the total amount of visitors to the site. I put the code at the bottom of the sidebar, and I occasionally peek at the numbers to see how many visitors have stopped by The Web Files since I started the site.
I’ve never had any problems with the Statcounter service, so if you are looking for a free stats program for your site check it out.
