On the web and in SEO terms, building backlinks is one tedious process.
From time to time, it can be as easy as snapping a finger. Not to mention that are a lot of places where you can create backlinks to your site by just submitting a form or filling our comments or write a guest post by just registering to a site.
But most of the time, the instances are getting rarer and rarer.
If you've ever tried building backlinks manually, then you know how cumbersome it can be. The reason it can be difficult is because you just can't get others' attention properly.
