Hi, before a couple of days my homepage(in signature) lose PR2 and now is n/a...but other pages kept their rankings 1 or 0 and some of them are very new. Also I lose my ranking for homepage keyword but other pages kept their rankings in google....Before my site lose ranking for some time because of google dance but never before lose pr....When I type site:mysite.com in google, there are all my pages expect my homepage? In webmaster tools I do not have any problems...and there is no warnings from google...I post my problem on google groups but there is no answer....strange..
I receive answer from google in webmaster tools that my site is ok and that they don't see any problem...and that my site does not violate google rules..... HAHAH....why than my homepage lose rank and still is deindexed from google
If you are de-indexed, the best thing to do is check your site for any problems. Probably, you have been affected by Panda Update. Put a re-inclusion request through Google Webmasters Tools.
Had you checked your robots.txt file and/or make sure you have not used any rel="canonical" link that points to other site.
I already send reinclusion request in webmaster tools and they said to me that everything is fine and that they do not see any problems with my homepage or site. I just check robots.txt and and I do not have any link that point to another site........ ..
Ah that's a big relief for you as Google rarely sends such notifications of being OK and No Violation Its good to see.. ANyways, I will suggest to update your XML sitemap and submit it to Google webmaster tools. Do some strong authority sites social bookmarking and RSS submission for getting your home page back to G.
I update my sitemap one time in a week, because of new pages that I add...I will try with some new sumbisions because I don't know what to do else
