Sub domain banned by google

I have created a subdomain for my main site, but google banned the sub domain does this will affect my main domain?

 

Yes, it will affect your main domain. I would ditch the domain all together if i were you.

 

Huh... that's really hurt any other way so that my main domain will not affected? I want to keep the subdomains that was banned by google because they are getting traffic from other search engine. Can I use robot.txt to solve this problem??

 

What makes you think the subdomain is banned?

 

because for the past months the site have more than 2000 pages index by google but suddenly yesterday for what every reason all are gone and don't get any single traffic from google now.

 

I had a subdomain that I'm 99.9% certain was banned by Google for some reason or another (it was an empty, disused forum that never took off) and it *didn't* affect the parent domain.. Every tool I used to check to see if it was banned said it was, and all the results disappeared (which is what made me check) but all is still good with the parent.

 

You cannot rely on the site: query to determine pages in the index any more. Use your domain name in quotes. If even one page shows up from the subdomain, you are not banned.

 

LOL..That was funny.
Just kidding. Be more patience and wait atleast a week lets see what will happen to your indexed pages. Goodluck.

 

What the hell is funny about it? The current and recent screw-ups from Google have adversely affected a lot of good (and white-hat) sites. That's not a laughing matter.

 

Definately not funny at all. I just about shit myself a few times in the last couple of months, one of my sites that had *finally* started ranking well and gaining traffic, all of a sudden went from over 1200 pages indexed to showing *nothing* and bounced back and forth like that every other day it seemed, and now only shows about 140 at any given time. I thought it was a goner for about a week straight..

Most of my sites have been up and down like a bloody toilet seat.. Crazy. I've been getting more traffic from Yahoo and MSN on a consistant basis now, simply because, well, they've been consistant, and my sites haven't been disappearing off the face of the Googlearth every time a black cat walks by my house.
