Wordpress as landing page for CPA

Hey guys,
so, I've got this brand new wordpress blog. I wrote an article, but I don't know how to make the monetization tool(aka content locker) to appear everytime one user go on the article link.

Can anyone be so kind to explain step by step how to do it?
-I use CPAgrip to get the code.
-My wordpress blog is one of those free sh*tty stuff, so I don't even know if it's possible to make the content locker to suddenly appear.
-My knowledge about IM language is more sh*tty than the free wordpress blog, so using words like: "hey dude just put the link in the html box", which apparently is what I have to do, is not enough: I don't know how to do it

Please BHW community, help me!!

Wordpress developers are Nazis that don't allow you to add Javascript to your own post. Sorry.

You can always make a separate HTML file, then link to it from the blogpost.
