Crawl Bots?

[Sven]

Hello I have seen a few sites that show when a Crawl Bot is on their website, I was curious is there a code to do this or how do they show it? I would love to know if I actually have any real people on my site or just a bunch of bots! Thanks

It has to be done server side. Crawlers dont generally use JS so a plugin woudn't be able to affect that anyway.
