Social media is taking over. Most CIOs already know this startling reality. It's a major player in marketing, tech support, customer management and sales. In fact, it's hard to think of a piece of IT where social media does not have at least a presence \u2014 if not outright dominance.In some ways, this change happened in a blink. Major companies such as PepsiCo and Merck now use social media to drive their brands and, in some instances, lead the charge for other marketing efforts. Companies such as McDonald's now use social media to launch new products. The one-on-one nature is an astounding IT effort when you think about how many people retweet a marketing message, asking questions and seeking support.According to an IBM survey of CIOs, social media is second only to direct sales in terms of overall priorities within an organization. You can see why when you do a simple search and find, for example, 8,000 mentions of @FedEx in one afternoon or 5,000 mentions of the @NASCAR brand in one hour on race day. Social media is a broad category that involves public data, users collaborating and commenting, video sharing and even comments on articles such as this one.\n\nHow-to: 12 Buzz-Worthy Social Media Success Stories\nOops: 10 Tech Company Social Media BloopersMost large companies use an enterprise-grade social media manager.

Teams can also find influencers based on their followers and real-time activity and then engage with them about the company brand.Shoutlet: Post Faster Thanks to Built-in Content LibraryShoutlet is another high-end tool that helps social media teams post to networks. Like most enterprise-grade tools, this tool provides the typical post scheduling, team approvals, task assignments, and detailed reporting functionality you'd expect. But there are some key features that go beyond the basic toolset for managing social network streams.One is a built-in content library. As teams post, they can quickly access an online repository of logos, photos or coupons. When a team member chooses an image, Shoutlet automatically determines whether that image will work on the selected social media platforms. The scheduler can hold a new post until a Facebook page has a certain number of likes, too.As for reports, there are detailed views but also ways to generate summaries for executives that show just the relevant facts, such as new likes for one Facebook page.Bottlenose Enterprise: Discover Trends, Compare Social Marketing CampaignsBottlenose, one of the most unique social media tools we've found for the enterprise, is more of a discovery tool to learn about brand sentiment and trends.

A company such as Ford could use Bottlenose to search for the term "truck" and see, in an instant, which topics are trending. Critical discussions \u2014 "heavy-duty" or "F-150" \u2014 would be seen in a larger size or brighter color.Related: 5 Things You Need to Know About Social AnalyticsThe reporting features are also unique. Social media managers can see historical data around a brand and make comparisons between brands \u2014 seeing how many discussions were taking place between Ford and Chevy over the past few months, for example.One key reason to use Bottlenose is to measure the effectiveness of a social media campaign. For example, when Acer hired Megan Fox to do an ad promoting a new laptop, it could have used Bottlenose to measure discussions on the brand or compare one marketing push against another, based on the timeframe and keywords.Salesforce Marketing Cloud: Multiple Enterprise Social PlatformsOne of the most powerful suites for managing enterprise social media is Salesforce Marketing Cloud. The tool includes Radian6, which helps companies analyze social media activity; Buddy Media, which is used to publish social media marketing materials; and the Social.com advertising platform, which helps teams create and manage large-scale social media rewards and coupons.Commentary: Salesforce.com Buys Radian6: Meet CRM 3.0Radian6 is powerful because of how it connects with so many social channels \u2014 the typical Twitter, LinkedIn and Facebook feeds as well as blogs, community sites, video channels and even the forms and comments on other posts. You can search for sentiment around a brand such as FedEx and see how many people are discussing that brand or how many complaints follow a snafu (say, tossing a box over a guardrail).
