It’s important that as social media managers we understand that the only constant in digital PR is change. Social media platforms update their algorithms regularly and new apps and trends are being created every day. While social media strategies are necessary PR plans, they are also flexible. Here’s what’s happened and changed in social media this week- you may need to rewrite those strategies and plans!

Instagram ads are a hit- which should come as no surprise to a social media manager. Organic reach on social media is extremely limited and social ads are becoming a necessary tool to achieving successful results. Just how successful are Instagram’s ads? Taco Bell’s following jumped 45% during its monthlong ad campaign. If that’s not a success, I don’t know what is!

Foursquare's new app, Swarm, is now live. Swarm is intended to be a convenient way to keep up with what your friends are doing, letting you check into venues, just like the Foursquare app, but it also lets you automatically share which neighborhood you're in. The company said the new Foursquare will come this summer. They created a series of blog posts explaining the new features, a smart move, as it makes users less hesitant to download the new app and take the plunge. The new features sound promising, but only time will tell if Foursquare dividing in two was a good move.

That’d buy a whole lot of dream homes: Pinterest is now worth $5 billion, and has plans to expand its global reach. While it’s not for every organization, it’s worth considering a presence on the social network, especially if you’re looking to reach women or sell a consumer product.
