How does it work?

For example, if a website visitor wants to read the full post on your blog, or see all images, get access to a download or pdf, sign up for a newsletter, get a cheat, or anything else, he/she will have to unlock the content with a simple "like" on Facebook, or a "tweet" on Twitter or a "+1" on Google and the user will get immediate full access. You simply add a shortcode [wpsociallock] in the post you want to lock and from where on you want it to be locked. Everything below the shortcode will be locked until unlocked by the website visitor.

This will create a ton of viral social media traffic from ALL their friends seeing the Like/Tweet/+1 who then in turn come and have a look on your website, also unlock the content via a Like/Tweet/+1 and voila, it's going viral! Not to mention it is creating a ton of backlinks automatically!
