Dear Gaourav SMO only Used for Increasing Traffic for your Site and its Create Branding for your product and also used for brand or Product awareness....

yes i want rank my web site

SMO brings traffic to your website. But I don't think it will able to provide your keyword ranking in SERP. If you want to rank your website then you should do SEO.
