3) in the google search, i see that every link have the same description (the first words of every description)… how could i set the description of the page (created with SEO) as google-description (the one that the user see during the research)?

Thank U David, but i have a question before start this.

If i import the backup of the site, i will keep my text, my css and all other stuff?

In other word, ill have a copy of the site?

Yes, i have one.
I was working on my site and at a certain point i saw an error. I used your plugin to reload my site and than i lost it.
