Force Your Visitors to + 1
Google plus sharelock is a wordpress plugin that uses content lockers and a traffic pop feature to force your visitors to +1 your content before it can be viewed. You can place as many as you like on any post or page, it doesnt matter.
You can even place them on a download page to force a +1 before your customer or prospect can download a product or free report you might have, anywhere you can think of.
