[Montse]

What tools can you teel me like keywordspy or SemRush that shows me what keywords my competitors are using to get traffic?

I use Open Site Explorer from SEOmoz  and SeoSpyGLass.

You could use Xenu or Screaming Frog to pull out all their page meta titles (assuming they are optimized for keywords).

To find the keywords they are really going for, use something like MajesticSEOs frash crawl index to see the top pages they are building links to... the anchor text used will be the give away.
