Explain with any idea

Post some high quality content in good article directories and take a backlink from them.
Do Forum submissions - Mention your website url as signature in forums.
Avoid reciprocal linking - Do not include other websites link in your site.
You can also buy ranking from SEOclerks.
Your site should have a clear hierarchy.
Always write your pages for your readers, not for Google.
