Well Shikha..!! If you are doing these activities then I think you have some knowledge about how to optimize a web site. But before off page activities you have to do some necessary on page activities like:

-Sitemap
-Robots
-Meta header information
-Set Google Webmaster and Analytics account to check websit's health and how to interact users with your site
-Set SMO plugins (Ex: facebook, twitter, google plus, You tube)
-Alt tag
-Check validation error
-Language and geo tags
-Check copycontent
-Check mirror site and more.

Now my suggestion is focus on live discussions like yahoo answering, chat forums, social media, rather than making only anchor text.
