Do you have a Webmaster Tools account for any of those de-indexed domains, david? Sometimes there can be clues in those accounts.

thanks Tedster for your answer,
yes I have an account for each of these websites. The interesting thing is that google lists my pages there. But not in its index, so I get 0 visitor from Google.

What are your linking strategies like as to common reciprocals, interlinking among sites, etc.? Does each site have a large set of unique inbounds?

|- All used to use the same template. I changed it today for one of the websites, in order to see if the problem comes from that. |
Were they also similar in nature? I mean, were there multiple sites set up to promote the same product and/or service?

Is there lots of cross linking on the sites that lost traffic?
If thats the case, I think Google may treat heavily cross linked sites as a single site so a problem on one site (say a bad neighbour on a shared server or loads of other things) may be causing the problem.

|...recently been de-indexed by Google and to a lesser extent by msn & yahoo. |
Would you clarify what you mean by de-indexed "to a lesser extent"? If you are seeing problems with all three major search engines, that makes me very suspicious of server troubles, or perhaps the htaccess file you mentioned.

|All have an .htaccess file, which may not be perfectly written |
I would make sure those are all perfect right away :/
