Both on page and off page SEO are very important for website promotion in search engines. Some on page seo techniques are title, meta tags, meta description, meta keywords, url, sitemaps, robot.txt files. Some off page SEO techniques are directory submission, profile submission, forum posting, article submission, blog commenting, social bookmarking and guest posting.
