Some SEOs use high-risk techniques when they're unnecessary. Stick with the white hat, ethical measures and it will pay off. Otherwise you will find your site getting de-indexed and have to start from scratch. Anyone disagree?
Yes I agree with you. Simply the Search engine eyes always focus the website focus on people or a search engine means. If the website trying to help the people it's increasing the rank. If focusing on search engine rather than people, consider negative rank and give negative rank. If over optimization and other blackhat SEO techniques may hurt the SEO rankings.
