Hello all!

I'm seeing current visitors in the hundreds on my small website.
Am I seeing robots, crawlers and such in this number?

I have no illusions about how popular (not very...) my small personal website is, but am curious as to why there are so many visitors counted.

Is that number a momentanous number or is the number showed persistent for a while?
How does this work?

Thanks for any insights!
