Social Media Growth 2006 to 2011

Dell Social MediaIn a previous post, social media growth from 2006 through 2010 was documented. As with that effort, there are no clear or easy answers when investigating the growth of social media sites over the past five years. No reliable or audited data exists for social media sites. Therefore, the numbers presented in the table below represent an estimate of total registered users for each of the sites investigated. The numbers are not assumed to be accurate, valid or reliable – they are as presented: estimates based on the best available public information. Data was collected for three social media sites and three blog hosting sites: Facebook, Twitter, LinkedIn,, Tumblr and Posterous. Estimates for the latter three represent the number of blogs hosted on the sites (not the number of unique bloggers, a much lower number, as estimated in the original post). The result of the change in reporting for the three blogging platforms, necessitated by the lack of data regarding number of unique bloggers, explains some of the exceptional growth reported below. No data for self-hosted blogs using is presented. As of December 2011, all variations of WordPress version 3 have been downloaded in excess of 65 million times.

SMM Growth Table 2011

As in the original post, the Compound Annual Growth Rate (GAGR) is calculated for each using the free Investopedia Compound Annual Growth Rate calculator available on their website.

When examining the charts individually, the growth patterns look similar. Globally, the total number of people using social media continues to increase. Facebook, alone, reports 11.45 percent of the global population as registered users. The average CAGR for the six social media sites is 443.66 percent ranging from 75.97 percent to 1,145.73 percent. Again, multiple factors contribute to this exceptional growth rate as compared to the data reported in 2010, including the change in reporting for blogs (total number of blogs hosted, not unique users) and the rapid growth of both Twitter and Posterous. Growth charts are presented below for each of the social media sites included in this investigation.

Facebook Growth 2006-2011

Twitter Growth 2006-2011

LinkedIn Growth 2006-2011 Growth 2006-2011

Tumblr Growth 2006-2011

Posterous Growth 2006-2011

When charted together, the domination of Facebook’s growth and share of voice in the social media world remains apparent. The launch of Google+ as a viable alternative to Facebook, although well received by the social media community, has not gained much traction in the broader audience. Data from Google+ will be included in next year’s update.

Social Media Growth 2006-2011 The final chart presented is social media share of voice. The inner ring contains the data from 2006 and the outer ring presents the data from 2011.

Social Media Share of Voice 2006-2011

It is clear that in terms of diffusion of innovation, social media remains in the growth stage. Equally as clear, but not reported above, is that more people globally are accessing social media from mobile devices. For marketers, the implications are irrefutable: get social and become mobile or risk losing share of voice in the social/mobile marketing era.


Predicting U.S. E-Commerce Growth Through 2013

How quickly is U.S. e-commerce expected to grow in the near future? In an earlier post, we looked at total U.S. e-commerce sales for the period 2000 through 2009. As illustrated at the end of that post, it is clear that growth in e-commerce plummeted from 2007 through 2009. Total U.S. sales via e-commerce in 2010 reached $166.5 billion, growing 15.28 percent over the previous year. As impressive as that is, it represents only 4.28 percent of total U.S. retail sales. While e-commerce as a percent of U.S. retail sales continues to grow, as illustrated in the table below, it accounts for less than five percent of total U.S. retail sales.

E-Commerce as a percent of total U.S. retail sales In a recent article co-written with Dr. Godwin C. Ariguzo (@ariguzo), we predict that by the end of 2013, total U.S. e-commerce sales will reach a level of $254.7 billion. This represents a compound annual growth rate (CAGR) of 52.94 percent for the period 2010-2013. Overall, the CAGR for the period 2000-2013 is projected to be 18.65 percent, which is less than the CAGR for the 2000-2010 period (19.70 percent). The table below presents the quarterly growth of U.S. e-commerce since 2000 and the projected growth per quarter through 2013. The projected growth was calculated using a Holt-Winters technique in time series analysis.

Holt Winters Projection U.S. E-Commerce Sales Through 2013Graphically, the projected annual growth for U.S. E-Commerce sales looks like this:

US E-Commerce Sales Trend Line through 2013

How does this compare to the overall growth rate in U.S. e-commerce reported in the earlier post? For consistency, the same summary tables were developed for this investigation (but are not included in the article with Dr. Ariguzo referenced above). The table below presents the actual growth rate through 2010 and the projected growth rate through 2013.

US E-Commerce Growth Rate Projected Thru 2013The recovery in U.S. e-commerce growth from 2009 to 2010 is impressive. We project the trend to continue through the end of 2011 and then to begin to decline slightly. The actual and projected growth rates are presented graphically below.

Charted Projected US E-Commerce Growth Rates Thru 2013

Please keep in mind that the figures presented are predictions based on a linear trend line obtained via time series analysis. As with any projections of future sales based on the history of past sales, the results are speculative at best. In addition, we believe that the rapid diffusion and adoption of mobile commerce (including via iPads and Tablets) may lead to higher than projected growth rates.

At what rate do you think U.S. e-commerce will grow over the next two years?

Social Media Marketing Still Generating Interest

Social Media Marketing by Rosaura OchoaIs interest in social media marketing waning, as reported by some researchers and pundits? The short answer is no. Using some creative code written for the R statistical analysis software program as highlighted in a blog entitled “Visualizing Wikipedia search statistics with R”, a graph documenting the number of daily searches for the term “Social Media Marketing” via Wikipedia is developed and presented below.

Wikipedia Search Traffic for Social Media Marketing

The results are interesting from a couple of perspectives. First, little to no search traffic on Wikipedia exists for Social Media Marketing (SMM) prior to the third quarter of 2008. Next, growth in the number of searches for the term SMM approximates a linear trendline with a positive slope for the period beginning with the third quarter of 2008 through the end of 2010. And finally, although the number of searches on Wikipedia for SMM in 2011 does not exhibit consistent growth, it is not declining either.

Additional research is needed in order to correlate the spikes in SMM search activity with events that may have caused these anomalies. More spikes are noticeable in 2011 than in any other time period. Overall, evidence suggests that interest in SMM is stable at about 1,000 searches per day. And, if you’re an optimist, based on the results for the past couple of weeks, interest in SMM may be entering another growth phase.

Do you think that interest in Social Media Marketing has peaked?
