my site is old maybe about 6 years i wasnt changing the content for all this time, i changed it before 2 mounts but the google bot scaned my page about 6 times so i don't think that will be a problem, but i will look for a cloaking or cloning.
I'm not quite sure that this can be a problem, but is it possibly that the meta description is the same in 4 pages of my site may this be a problem and google consider these pages as a clones. Cause one of these page is at the 530 place wich i mention in the first post but it wasnt the page wich was at the 8 place(at the 8 place was the index.html)
