Hi friends,
sitemap added .. all pages are indexed. no duplicate content. no notification on the webmaster tool. any suggestion on what do I do?

Can you share a link of your website?

Google Chrome: Click Chrome's menu button, select Settings, and check the Show Home button option under appearance. Click the Change option and change the home page. You should also click the Set pages option under On startup and ensure that no additional web pages are set to load at startup.

Submit a sitemap.
Make sure that people know about your site.
Provide comprehensive link navigation within your site.
Submit an indexing request for your homepage.
Sites that use URL parameters rather than URL paths or page names can be harder to crawl.
