Thanks for replay,
I have webmaster tools and there are not manual action in my website.
In moz open site explorer i only see 1844 links. LJ Digital can you tell me what tools you user, because you find 62,000 links from only 235 domains.
I forget to tell that in my keyword i was in the first (and top) page of google but now for all keyword i am in the page 2 or 3 or 4.
Thanks
