When I try to see how many pages I got indexed in google. I get 41 pages indexed when I do: site:domain.com and 0 results when i do site:http://www.domain.com any information?
It basically indexes the site's as either http://domainname.com or http://www.domainname.com. I wouldn't worry about it to much, as long as your listed with one of those sections, it's all good.
Depends if you use http://www.domain.com or http://domain.com for your linking campaign. Google will see this as 2 different domains. if you search for site:http://www.domain.com and have 0 results then it seems that you promote http://domain.com on your linking campaign... This is just my opinion, for a more specific analysis, the domain name will be helpful...
Do some seo work and add website map to google webmaster tool . This will help you to get indexed easily . This happens with me to when i search for domain name i get so any back links and when i search for something in my domain name i get few results but now they are increasing slowly .
As stated above, go to your free Google Webmaster Tools account. Click on Tools > Set Preferred Domain and select your choice, with or without the www. I have my preferred domain set with the www, and my site: searches show the exact same number of pages with or without the www. I think that if you select your preferred domain in GWTools, your problem will be cured. Best wishes.
Ditto... I personally think this has nothing to do with SEO. I also have mine set to use the www prefix. Looks better in the URL bar. OHH... You should probably do a .HTACCESS Re-direct for domain.com to www.domain.com or vice versa... all depends if you know how to do a 301 re-direct or not.
