To repeat, top search engines like Google give more credit to the site, which has the advocacy of other websites. But, if the search engine finds quality backlinks with illicit content, the rank remains low. Besides, social media and blog commenting are the easiest ways for a bulk amount of quality backlinks. Similarly, guest posting and submitting a blog to the Blog catalog and Technorati are a better alternative for backlinks. And, guest posting is always good for building backlinks. Also, participating in different forums relating to your niche can bid for your backlink.
