How to add a Facebook like popup on a wordpress site

[The Truth]

I want some help to add a Facebook like popup on my WordPress site which I am not able to find. I want that if someone clicks on a article he can see a Facebook popup window. And after liking that page only it must appear or else it must not work. I had tried looking around but it looks a complicated procedure. I am not having any development knowledge so I cannot do coding stuff here. Is there a ready to use plugin for the same. That can add a popup box on the article pages of WordPress.

There are few things needed before using such plugins. Like you cannot force a user to like your Facebook page. Many sites give you a locked content and force you to visit the fb page or twitter page and then only it is unlocked. It is essential that you must use a plugin that has timeout settings. Or else it can cause ranking issue with your website. There is one that you can try using is Social Traffic popup. Try to test a few different plugins and check that they work well. There must be enough settings in it.
