first of all many thanks for your really good advices - I´m learning daily about SE since 2 years and it´s the first time, I´m really confused, sometimes I tried something out and lost some positions in SE, but got them all back - but never was out of the index, it´s only at G and some other, which are related to G - in Altavista a.s.o I´m still on the first page with ALL my sites I ever made, but G is still (and will be) the most popular SE, so that´s a big problem for me and my customer.
now to your statement:
(1) does your site have a unique IP....yes ok....no get one
(yes and no, I rent webspace as a reseller from a big provider, so my domains have all the same IP, but on one resseller-acount, there are only a few webpages, around 100 to 500
But still the other sites, which has not been linked with LT are still at very good psotions at G
(2)Is your site listed in DMOZ...if not try to get listed.
from the affected sites, there is no one listed in DMOZ, excatly, there are only less of my sites listed in dmoz, I´m still trying to get listet, always looking for any kind of related category, and of course with an editor, but it´s really horribly - maybe you know some kind of advice
...I´m very new here, so I didn´t read the hole forum now, maybe I find also some answers how to get listed in DMOZ
(3) Submit your site again to google...
for sure, at now I did it yesterday with one of the sites, because I don´t want make a mistake with all site together again, maybe it´s better to try one possibilty with one site, and another possibilty with another site, than to write all things down with date a.s.o. and if something happens, to make the changes to the other sites
Something bad that can also happen !!
A website did copy text from one of my clients and it did result in the fact that the origional website from my client was out for a while
I don´t think so, because there is not so much content on all my indexpages, which would someone would be intereste in - and this things (out of G index) happened with 5 from 6 sites, with which I tried LT, one site is still in, but back from position 1 to 96
