Joke, of course.

More seriously, scripted counters tend NOT to count visitors very well. For two simple cases, even if one assumes that every visitor enters at the default page, that vistor will be counted twice if s/he leaves and comes back and may (depending on the sophistication of the design of the counter program) be counted if s/he browses from the default page to a sub-page and back again.

You could deal with some of this with cookies (but some users will reject them), and if you have "no clue how to do it" then even with the wealth of nodes here on cookies, you have a serious learning curve to climb. One can hope you will do so, and the Monks will undoubtedly be pleased to help. On asking for help and Perl Monks Approved HTML tags provide many hints on how to ask for that.

And (but NOT as an alternative; rather, as a supplement) You may wish to look at some previous advice on a similar question, at Visitors Counter.

On the other hand, most hosts will provide some sort of stats, often in a directory so named. Some of those will offer (pretty) graphic data: visitors, "unique" (not really) IPs, etc. If the object is merely to get a general idea (and give the boss something to look at), those should suffice.
