difference of www1,2,3 and search results

[Vicky06]

Hello there :-)

I´ve been reading here for quite a while now but never posted anything yet... I must say I am not an expert at all. So maybe my question is toooo easy for you ...

When I go on searching for one of my main keywords on www1 www2 www3 and compare those results with the results shown... the search results are faaaaar away from the ones at www 1, 2, 3. I know about daily fluctuation... but those results have not much to do with the www1... results. Can someohne explain this to me? What does Google mean with daily fluctuation? How far do they go (not in detail *ggg* but maybe an overview).

>>>> Frustration on
When I see the top 10 for this main keyword... 8 out of 10 results are dublicate content (free blogs with exactly the same content word by word). The 2nd page looks a bit better... only 5 out of 10. So far about the question of dublicte content I read a few times here.
Frustration off >>>

Sorry about my baaaad English. I hope you could understand what I´m talking about. :-)

Thanks for your help :-)
