As a Facebook page admin, you are able to invite people who liked your posts or ads to like your page, this is a cool feature that helps you to grow your page likes for free over time.
I will explain this more further in this post.
However this is a manual process and you have to click the invite button for each person, which can be tedious especially if you get a lot of likes on your posts or ads.
I have made this bookmarklet that does the clicking for you.
Simply drag and drop the button below into your browsers bookmarks bar to use it.
To use it, simply open the popup where you can invite people to like your page and hit this bookmark in your toolbar, sit back and enjoy.
Hope you found this useful!
