Hi Eblan,
Thanks for your response i want can you give me any link where i can found high quality directories list? also can i create all backlinks for main site like ( www.domain.com ) bcoz i have also keywords for my subpages like ( www.domain.com/target-keyword.html )
Some one told me when you start off page Optimization add daily backlinks for your site like that ( 100 directories, 80 Social bookmarking, 75 blog comment, 5 articles ) for that reason i asked in my Question the number of backlinks daily.
I was completed On-Page Optimization and my site links is SEO friendly names like "www.mysite.com/target-keyword.html".
Also added Google Webmaster's tools and Google Analytics & created social media accounts too.
Many Thanks again for your great information.
