Web Crawlers
« on: December 03, 2011, 07:33:34 pm »
I'm curious to know how Web Crawlers, Spiders, and Bots work. More often than not, when checking to see who is online, Guest (Spiders) will be attempting to post in existing threads. Is this a glitch in the software as I can't really think there are that many dumb people out there that would continually try to do this if they haven't yet registered on the site.


I also get a lot of people "Registering to the forum", but never get any email notification. And when I check in Admin and look in the Waiting for Approval, there isn't any there to approve.


Just odd.

Well the bots click on every link they see. They also record all text on the page, so if there's the word "mario" a hundred times on a page and I go to google and type in "mario" then I can expect your forum to be in between pages 1 - 30 on google because the bot can expect there'll be more information on mario which would make your forum more relevant.

Okay. Thanks.


Any info regarding "Registering to Forum" or "Posting In Thread" that I see a lot when checking to see who is online. I know that the people/bots that are posting are not in fact registered with the forum.

Well the bot doesn't have common sense, cause it's a bot.... If it sees a link, it goes there. They might be stuck at that link because they can't get past it.

Well, if a Bot is stuck at a link, then I guess I shouldn't be too concerned with them rising up and taking over the human race then.  ;D

They might be smart enough to all pile up on a website and overload the server :P

They automatically come to your forum. No need to activate them whatsoever

They'll be listed under guests. If you see a random guest every now and then, it's quite possible they are bots. You just have to check their IPs.

Is there a difference between real IP's and those of Bot IP's? What do we look for that tells us one way or another?

I can't confirm if this list is valid but this is a list of known ip addresses for Google bots: http://www.iplists.com/google.txt

Click on the IP next to the name Guest, and it should bring up a "Track IP" page.

Go down to "Look up IP on a regional whois-server" and click on the bolded link. From here you will be taken to a lookup page and it will tell you information about that IP address, including who it is registered to. If it's google or yahoo, etc. then it will tell you this.
