Thanks for including that screenshot Iris.
Regarding villasdiani.com/?db being shown as one of your top visited pages, I think (and perhaps someone from Moz will confirm this) that because you have been receiving links to your site to villasdiani.com/?db and that is probably also being recording in your Google Analytics, it considers that to be a page when it actually isn't.
As I mentioned earlier in our conversation on this, villasdiani.com and villasdiani.com/?db are actually go to the same page. They are just seen as different because you have had inbound links to villasdiani.com/?db and as said before when the query string ?db is not processed by the web server because there is not recognised, it is then ignored.
I have run a search to see what external sites/pages are linking to villasdiani.com/?db and the following were some of the results:
http://dianibeach.com/airservices/index.html
http://dianibeach.com/apartments/index.htm
http://dianibeach.com/bedbreakfast/index.htm
http://dianibeach.com/books
http://dianibeach.com/carhire
http://dianibeach.com/golf
and they are showing as all having had the anchor text of "Raul".
Is Raul the name of this guy you know who said he was giving links to your site from the footer of your site?
I have checked the source code of some of the pages above villasdiani.com/?db.
The data being reported by Moz for these type of reports is not totally up to date but taken from the last crawl they made. You said at the start of this thread that you had asked this guy to remove the links to your site. Could it be that in the last few days or so he has done that and so from now on you won't be getting any links to villasdiani.com/?db ?
That's possible, but I cannot say that is definitive, but it would explain what you have been seeing.
Maybe someone from the Moz team can throw some light on this or one of the other more knowledgeable forum members.
