Hai,, I think you done Social bookmarking, Directory submission in less quality site, u will try buy High quality home page text link it will give strong back links and your website get google index page (SERP position increase)... I have own high quality site.. u want pm me...
firstly check your website page that it is indexed by the Google or not... after indexing to all the pages do the social bookmarking on top most sites i.e. Digg,Stumple Upon etc. and do more and more web directory and do off page optimization task....
The submission that you do does take some time to be cached by Google and in the meanwhile work on the submissions and lay more emphasis on the quality of the work you do rather than the quantity. I would also suggest you to optimize your website on-page so that it will provide a stream of fresh air eradicating any errors if there are any.
Dear...as you are saying that you done directories submission, social bookmarking, web 2.0 submission, forum posting, Business profile creating. but it depend on quality backlinks..it may happen, you got low quality backlinks and not update your website with unique content because in SEO...we know content is the king
I think Blog creation and blog posting are the best way for increase back links and traffic on your website....You need to work on your content. Don't write content for Google, write content for users and then submit your site to many submission sites. It'll be on higher position easily.
