That's right, your website is hiding some valuable information from you. It knows who is visiting it, where they are going, and even more importantly - why they leave!
Understanding your websites traffic statistics, logs, and gathered information is like asking someone to blindfold you while you are driving.
Those statistics aren't really hiding, but a majority of webmasters don't use them because it's just a bunch of overwhelming numbers, that really don't make sense to them. If you have a Cpanel based host, most of statistics you will ever need is at your fingertips.
I know first thing I go for once I get in my website statistics is referrers, and keywords. I want to know where my traffic is coming from and from what keywords.
There are some things you want to see in your statistics, and some things you don't.
1.) "Stickiness"- You want to see people staying on your page for more than a few seconds. If you have a ton of visitors and none of them stay on your site for more than a few seconds, you have a problem and it's time to address it. Figure out WHY they are leaving, make those changes and then reanalyze in a week.
2.) Most Requested Pages- Your statistics can tell you most requested pages. Those are pages that visitors go to most. The least requested pages may require some work or content added to increase their popularity.
