Where Promote Keywords in off page

Hi, I am doing Social Bookmarking, tell me where we can promote our website's keywords in social bookmarking sites, in Title or Tags...

 

Use main keywords in title and keywords in meta tag option...

 

we can promote our website's keywords on title, how much keywords we can use in title..?

 

You can use maximum of three keywords separating with "|" Or less than that as per limit of characters on social bookmarking site..And also you can create a description type attractive title including your main keyword..I would like to suggest you to analyze previous stories submitted on social bookmarking site and take an idea that how others have used title with their keywords...

 

Create stuff using with description share on social networking site

 

Do forum posting, blog commenting, directory submission and also use social media optimisation.

 

You cannot use on page keywords for off page :L
