In respect to the comments about the .htaccess file and the bad bots, I can only tell that since implemented, I save per month several GBs bandwidth. And I admit that I have paranoia, but I have already very good reasons for that. Anyway, lets stay on topic.
About the sites being de-indexed, what the hell are you talking about? I am just wondering what are these results buddy:
Site Search:
site:business-trader.com.au - Google Search
Results 1 - 10 of about 2,710 from business-trader.com.au. (0.03 seconds)
Cache:
Businesses for Sale - Buy or Sell Australian Business for Sale
This is Google's cache of
Businesses for Sale - Buy or Sell Australian Business for Sale. It is a snapshot of the page as it appeared on 23 Jul 2008 09:39:31 GMT. The
current page could have changed in the meantime.
and
Site Search:
site:business-sale.com.au - Google Search
Results 1 - 10 of about 206 from business-sale.com.au. (0.12 seconds)
Cache:
This is Google's cache of
Online Business for Sale - Australian Businesses for Sale. It is a snapshot of the page as it appeared on 22 Jul 2008 08:17:21 GMT. The
current page could have changed in the meantime.
Or is the discussion about another site and I missed something?
From my perspective, I can only tell that the site has other serious issues than just being hurt implementing those rules in the .htaccess file, since those cannot happen over night:
Just one example: Doing a site search
site:business-trader.com.au this page comes first:
Business for Sale Australia | Buy & Sell Australian Businesses for Sale
After all, it is obvious that you have bigger problems than what you are crying about.
Good luck.
