Anyone else noticed this Google bot?

Just noticed a new google bot crwaler hiting my javascript tracker.

Hi all,

I run a number of web sites and use a JavaScript based system to track my visitors (extreme tracker).

Was noticing today a number of hits on a particular site by the following google bot:

crawl-66-249-65-33.googlebot.com

I have never seen any crawlers come up on the tracker logs before (as it is a Javascript based system, it normally only tracks javascript enabled “real” browsers). This particular bot is very new, not to mention very interesting as it very much behaves like a browser.

Wondering if anyone else has noticed it and maybe can shade some more light on its purpose.

Seasons greetings to all and happy new year.

As long as the url to your track script is raw in the js - it will be followed. Gbot just rips anything that looks like an http out of your js and follows it. Last time I looked, I think the extreme tracker was follow'able.

That's what made me wonder, the extreme tracker Java code is placed raw on the said page (not within a js file), it uses JavaScript to construct an img src string (including the referrer, screen resolution etc). It then uses a "document.write" statement to write back the img string to the browser and log the user. I have never seen this happening before, i use the same method of tracking on 10 other sites. Googlebot never left a mark on any of them. I find it very intresting.

See copy of the tracker code below (i replaced all ">" by ")" respectively):

(a target="_top" href="http://t.extreme-dm.com/?login=my_login_name")
(img src="http://t1.extreme-dm.com/i.gif"
border=0 alt="")(/a)(script language="javascript1.2")(!--
EXs=screen;EXw=EXs.width;navigator.appName!="Netscape"?
EXb=EXs.colorDepth:EXb=EXs.pixelDepth;//--)
(/script)(script language="javascript")(!--
EXd=document;EXw?"":EXw="na";EXb?"":EXb="na";
EXd.write("(img src=\"http://t0.extreme-dm.com",
"/c.g?tag=my_login_name&j=y&srw="+EXw+"&srb="+EXb+"&",
"l="+escape(EXd.referrer)+"\" height=1 width=1)");//--)
(/script)(noscript)(img height=1 width=1 alt=""
src="http://t0.extreme-dm.com/c.g?tag=my_login_name&j=n")(/noscript)

Web_speed -

I had alreay posted this in the other thread, but to be consistent...

I've got a lot of attention from:
crawl-66-249-65-113.googlebot.com
crawl-66-249-66-79.googlebot.com

In fact, overall crawl activity from Google bot is a great deal higher in December (3,700 pages) compared to November (1,800 pages). The website has roughly 1,000 pages.

In fact, I just saw another 100 pages picked up my Mozilla Googlebot in the past hour or so. I'm not sure if that's good or bad. I will say that I've introduced some pretty heavy javascript on about 50 new pages.

BillyS,

Did you notice any Javascript parsing by this bot?
