The Plus One 2 Unlock plugin allows to lock a part of content on a page until the user clicks on the Google Plus One Button. What’s more, you can show the locker only for Google Plus users, and hide it for others. Do you know Google places sites that have more plusoners higher in the search results? Use the Plus One 2 Unlock plugin on your site and give people a reason why they need to click the button. Even if people like your content they don’t click the buttons because they don’t worry about you, your benefits or your traffic. It’s not their problem. But ask people to “pay” with a +1 to get access to your content, to get discount, to download, to watch a video, to view a funny picture or so. And it will start to work as it should be!
