In today’s economic climate, marketers are trying to do more with less by making more efficient media buys. The most cost efficient, and often most trusted form of media is word of mouth. Senior Forrester Research Analyst Jeremiah Owyang called word of mouth the holy grail of marketing.

Organizations like hospitals rely heavily on word of mouth to remain top of mind for patients choosing a health care institution for their treatment. Lee Aase from the Mayo Clinic presented at the Community 2.0 Conference in San Francisco on how the Mayo Clinic is using social media to share their message with the existing community and extend the reputation built over many decades through word of mouth.

As millions of new users continue to join and use Twitter, retweets are quickly becoming the most effective way to socially endorse a brand or comment. A retweet is repeating someone else’s quote or tweet on Twitter. Owyang’s blog post called retweets the core essence of viral content spreading, as the content of a retweet was so valuable and important to that user that he or she was willing to share it with their network. And Forrester research indicates that Twitter users are brand sensitive.

Retweets are one way to make measuring and monitoring word of mouth more tangible and accurate. Repeets.com, a new site launched this week by our own Adam Coomes, tracks the hottest and most retweeted tweets of the day, week and month, providing a snapshot view of the most shared tweets. Mesiab Labs has launched www.retweet.com, an online petition users can sign to endorse retweets with the hope of creating enough support that Twitter will make an official Retweet button.

The chart below shows the steady rise of retweet or RT references online. Check out the spike from April to May 2009. How is your brand using and measuring retweets?

Twenty years ago, when a customer had a bad experience and decided to complain, he told a few friends and that was that. Today, a customer can share a bad experience with millions of people instantly through blogs, Twitter, Facebook and other social media tools. And when that customer happens to be NBC Parks and Recreation star Aziz Ansari, people listen.

Ansari went to the AMC Theater in Burbank on May 11 to see Star Trek: The IMAX Experience. He sent out a tweet that night claiming he was charged an extra $5 for a slightly bigger screen and not the full IMAX experience. Ansari then wrote a blog post asking readers to boycott fake IMAX experiences at Regal and AMC Theaters.

Slashfilm made a post on Digital IMAX supporting Ansari. CHUD and New York Magazine followed suit. Within hours, Ansari tweeted that he also had the support of Deadline Hollywood, Fark, Buzzfeed, Rotten Tomatoes, Onion AV Club, CinemaBlend, Collider and more. His story made the Digg homepage with 2435 Diggs.

Richard Gelfond, CEO of IMAX, defended IMAX against Ansari’s rant and other blogs covering the issue. Though he seemed to brush off Ansari’s comments, saying, “The overwhelming majority of comments on that guy’s blog this morning, more than 90% of them, are vehemently disagreeing with him. And consumers are confirming this with their continued purchases of tickets.” Ansari blogged a response, asking others to share their experiences online.

How much impact can one person have? Check out the trend chart below measuring online chatter. Positive sentiment around IMAX was extremely high the week leading up to Ansari’s rant, with more than 80% positive chatter. Positivity has gone down sharply to 60% over the past two days, with negativity shooting up from less than 10% to nearly 40% of IMAX posts.

We also analyzed keywords around the word IMAX over the last few days. The word fake appeared in 8% and Ansari appeared in 5% of posts. Will the chatter lead to a decrease in customers? How do you think IMAX should respond? Is your brand prepared to handle the power customers have today?

The April 2009 Social Radar Top 50 measures the brands with the most active Web presence based on overall online conversation volume. To create the Top 50 list, we used Social Radar to analyze millions of blog posts, news feeds, forums, social networks and Twitter posts to aggregate a list of the words and brands mentioned most frequently on the Web during April 2009. The list measures the number of unique individuals or sources that posted content about each brand during April 2009 rather than the overall number of mentions, which would be more heavily influenced by big fans who post frequently about a specific brand.

Twitter once again dominates the Top 50 list in April 2009. Already the hottest brand on our March list by a wide margin, Twitter accumulated an additional 10% in chatter in April.

Content sharing website Digg joined the Top 50 this month thanks in part to the April 2 launch of the DiggBar. Enterprise software company Oracle also joined the list with an increase in chatter due to its April 20 acquisition of Sun Microsystems. And as the NBA and NHL Playoffs heated up in April, the NHL joined the Top 50 while the NBA jumped 9 spots.

Dell dropped 23 spots this month as buzz around the March announcement of the new Dell Adamo faded. Kindle also dropped out of the Top 50 as hype around the Kindle 2 subsided.

Conversely, CNN jumped up 10 spots thanks to the race to a million Twitter followers with Ashton Kutcher. IBM also jumped four spots thanks to increasing focus on social media.

Land Rover recently became the first brand to execute a national Twitter campaign to promote its newest models’ debuts at the 2009 New York Auto Show.

The campaign promoted hashtag #LRNY in out-of-home venues like billboards and taxi TVs to spread the word of Land Rover’s Twitter efforts.

Was it a success? The campaign cost Land Rover nearly nothing and generated a significant increase in buzz leading up to the New York Auto Show.

According to a recent study, the best way to get Internet users to visit your website or follow your brand is brand mentions, not banner ads, pop-up ads, e-mail offers and sponsored links. So increased word-of-mouth chatter could be considered one form of success for Land Rover.

But what were people saying? Sentiment around Land Rover was largely positive during the spike in chatter, with words like “best” and “luxurious” appearing high in the results.

Digging a bit deeper, we wanted to identify the top influencers on Land Rover during the first few weeks in April. Using Social Radar, we created the visual ecosystem below showing some of the most influential sources and how they connected.

The visual is based on metrics such as the ratio of content matching the Land Rover query, post frequency, inbound link frequency, outbound link frequency, and more. For additional info, Social Radar users can click on any of the bubbles to see stats.

Nearly 45% of Internet users will visit a social network at least once per month, according to eMarketer, but social network advertising represents just 5% of overall online ad dollars. Should more companies follow Land Rover’s lead?

More importantly, can Land Rover use excitement around the campaign to sustain relationships with customers online?

We received a lot of feedback on yesterday’s Social Radar Top 50 (March 2009) post and wanted to provide some additional thoughts. A brand is a promise; a collective of perceptions. Our Social Radar Top 50 Social Brands list was calculated based on overall conversation volume, including millions of blog posts, news feeds, forums, social networks and Twitter posts. To determine our top 50 brands, we aggregated a massive list of thousands of the words and brands on the web during March 2009, then conducted further analysis to rank the results. Our list measures the number of unique individuals or sources that posted content about each brand during March 2009 rather than the overall number of mentions, which would be more heavily influenced by big fans who post frequently about a specific brand.

We did not base our list on number of searches, which you could easily do using Google Trends. We measured conversations and web chatter. If you’re a brand manager, do you want to know who’s searching for your brand? Absolutely. Do you also want to know how many people are talking about your product online? Absolutely. If you need to do some home repair, say, fix your cabinets, you’ll probably start with a Google search. But are you going to blog about your experience? Probably not unless it’s extraordinarily good or bad.

We also did not base our list on revenues. The Business Week / Interbrand list of top global brands for 2008 is evaluated based on how much the brand is likely to earn for the company in the future. Interbrand uses a combination of analysts’ projections, company financial documents, and its own qualitative and quantitative analysis to arrive at a net present value of those earnings.

Coke and McDonald’s are both on Interbrand’s top 10 list, but both brands were outside of our top 50. Social media doesn’t necessarily correlate to market share. How often are you blogging about the Coke you bought from the vending machine? On the other hand, technology is always advancing and people often chat or post about new updates and features. Check out the chart below comparing chatter for Coke, McDonald’s and iPhone throughout March 2009.

There are many reasons why products have large market share. Microsoft products are still predominately used in many corporate settings, and in some cases employees at those corporations might prefer to use Apple products but aren’t given the choice. Apple’s market share has increased dramatically in the last few years. Who knows if Apple will surpass Microsoft in the future, but they are generating more buzz than Microsoft on the web thanks to passionate Mac and iPhone users.

Social media is evolving. Companies are just now beginning to hire social media strategists to interact with consumers. Social media is still a low priority for many large corporations because of lack of perceived ROI. So they are still experimenting with ways to become part of the conversation. Companies that can create real-time interaction and involvement with their customers will be best prepared to succeed in the new media world. How can companies capitalize on or increase online buzz? Will it translate to increased revenue in the future?

Update 04/08/09: For more details on how we determine our ranking, view The new rules of branding

If sheer volume of conversation is any indication, Twitter is the hottest brand in the market. Twitter dominates a tech-heavy list of brands in our March 2009 Social Radar Top 50. The Social Radar Top 50 measures the most social brands by the number of unique topics of conversation. These brands are top of mind for consumers and bloggers today — Social Radar determined rankings according to the number of individual websites with at least one post about each brand to accurately capture the brand’s reach across the web.

The list below is based on overall conversation volume through the month of March 2009, including blog posts, news feeds, forums, social networks and Twitter posts. The +/- number represents the ranking change since February 2009.
