Sincere comments on other related websites and/or blogs are a great way to create backlinks to your website. Suitable backlinks are great for SEO as well as traffic generation (i.e. drawing new visitors to your site). Have you ever wondered how other people manage to have an custom image next to theirs (making it more personal) while you are left with mr/s. “no name” image?
