Off Page Optimization is the hardest thing to do in SEO, unlike On Page Optimization which I discuss in my previous article you have the control in everything on your page but in Off Page Optimization you're not. Off Page Optimization means building authority of your blog through your backlinks, these include Guest Posting, Blog Commenting, Social Media, Bookmarking, Press Releases and many more. Google divided the backlinks in two parts the good backlinks and bad backlinks. Bad backlinks refer to any spammy backlinks that you've made in order to trick some web users and to pass juice back to your blog, it can also lead your blog to drop down in the Google ranking. As you read this article you are able to know the different techniques in doing the right Off Page Optimization on your blog.
Guest PostingGuest posting is the best way to have a strong backlink to your blog way back in the year 2013 and below. It is also the best way to gain credibility as a blogger and authority to your blog. But if you are still using guest posting to gain dofollow backlink in 2014 you should stop it, because Google started to treat this as a kind of spammy practice.
Many bloggers still continuing this kind of practice to drive only a traffic without passing the link juice on the other site which is OK. To start guest posting you must check first whether the site having a huge amount of traffic per day which is very important. Also, you must do guest posting only on every site that is related to your topics to avoid getting high bounce rate. If you are linking your blog do not forget to use nofollow attribute.
