Well to achieve more and more leads you need to take care on both sides of the site
What i exactly mean is do the proper On Page & Off Page
On-Page
1. Select proper keywords
2. Check for the Titles, Description and the Heading Tags
On Off-Page(this needs to be taken more care of once the on-page of the site is done and the site is launched). All Off Page Techniques like Blog Posting(Ping the blogs and Submit blogs afterwards), Articles Posting, Forum Posting, Social Bookmarking, etc. This all Techniques need to be done in number of 500 to 700 per month with a fresh content on posting side, because content is the king in
SEO. As any search engine will always prefer the fresh and new content while crawling and avoid duplications and spamming of links.
After this much practice per month...your site will definitely will achieve good rank in any search engine(but backlinks from the off-page should be relevant and meaningful)....and then will get good number of visitors which will lead into good sales.
