Foursquare Check-in : Similar to Places, Foursquare has 20 million users with mobile phones checking into restaurants, hairdressing salons and doctors’ surgeries. They win badges and special offers for participating. Google collects as many check-in services as it can, aggregates the reviews and then displays them.

Like last year, I enlisted in help from my followers on Twitter, many of whom gave me some great posts to add to this list. Like last year, if your article is highlighted in this comprehensive post, there’s a badge for you to proudly celebrate this achievement on your site. It’s definitely a worthwhile read.
Expert insights. Personalized for you.
