As noted above create a home page and let it show how many people are visiting your site - it's an impartial and transparent way of letting them see as it is generated by the system. I've done this on all three of my sites as it's not just a way of showing how many visits you receive, it also allows you direct visitors to where you would like them to be, or view what you consider to be important. After that they can find their own way around your site - it's a win-win option
