supplemental results, penalization, change of algorithm? Cratima has a problem!

[Cratima]

I am confronting with a problem regarding the SEO, SEM of Cratima website.
I use some indicators for my managerial analysis of the Internet marketing job done for this website.
One of this indicators is the number of results at Google when searching for the keyword “ cratima “
( I do this because I think that if this indicator grows it means that the amount of information about the company grows and it is good for our notoriety ) .
On 24th of November 2007 our cratima.com domain name expired (on 28th was reactivated) and 7 days later the number of results dropped from 60000 to 6000. I assumed that the expiration was the reason and don't take the problem too serious. The thing is that the number of results never came back to around 60000 again.
Now, I think that the amount of information hasn't disappeared from the web.
Please give me a clue, or help me with an article, some opinions.
I've searched the web and read about google hell, supplemental results etc. but I haven't found anything to explain or resolve this problem.
Has google changed the algorithm and many info about cratima on the web had stopped being indexed?
Has google another penalization policy that you can prompt me to read?
Has the domain expiration anything to do with this in the first place?
All the others indicators that I use for the managerial analysis are working just fine: alexa, pr, visits..


Thanks !

I think the the problem is the quality of the results. Many of the results for 'cratima' resulted from forum posts that have probably been deemed to no longer add value and as a result been dropped from the index.

The reason could be your use of flash as it means the site is all but invisible to the search engines. If it follows a link from a forum post or blog comment and can't see anything useful for the visitor then it may well discount the link.

A thought for you. How many people visited the site from all those forums in the last month? If the answer is not many then that will give you an indicator of the value of those links.
