hi!guys
help me how i indexed my site and how i achieved rank for my site??

You can start with making sure you have a valid XML sitemap and submitting it to Google Webmaster Tools and Bing Webmaster Tools.

The second part of your question regarding rank .. You need to host quality, unique content on your site. Back links to your site from other sites with high PR will be very helpful.

Do social bookmarking, article marketing, yahoo answers, guest posting, forum posting, video creation and social media.

i think that's good method .....for indexing
