Social Media and Customer Satisfaction Research

Friday, July 30th, 2010

This past Monday I moderated a panel of thought leaders in market research to ponder the question: “How Will Social Media Change Customer Satisfaction and Loyalty Research?” The event was sponsored by the American Marketing Association, and included participants from GfK, Maritz, MARC, SAS, Market Tools, and Versta Research.

One of the fascinating insights to emerge from our discussion was that social media is not only a new channel of information and data, but that it is fundamentally different from previous channels of data. As such, it opens up new areas of inquiry for our efforts. What is that fundamental difference? It is the networked nature of social media. As we code and tabulate people’s comments on social media as part of our CS&L research, potentially we have access to the networks of each person whose comments we are analyzing. We can know how many people are reading each comment, we can measure how strong and extensive the network of influence is, where it overlaps important segments of customers, and so on.

The implications of this are huge. The impact of loyalty among one’s best customers can now be defined not only in terms of how much they buy and how “sticky” they are, but also in terms of their influence among other customers and prospects. Smart CS&L research will not count everyone’s opinion the same, but will give more weight to those occupying central nodes of critical networks. There are implications for sampling as well. Is true random sampling necessary, or can “networked” sampling provided sufficient entry points that give visibility into the full population of customers?

In my view, this sort of network analysis will bring about a seismic shift in CS&L research, though not all panelists agreed. We were split about 50/50 on whether social media constitutes just one more channel of data to integrate, bringing greater precision to what we’ve always done, or whether it represents a more radical departure. A full report of our panel’s deliberations will be presented in the October 2010 issue of Marketing News, the AMA’s monthly magazine.

The stimulating discussion among panelists also highlighted the importance of remembering that good CS&L research requires ongoing thoughtfulness, intelligence, and curiosity. New tools and technologies are often easy to install, but their value is in offering new opportunities to bring deeper understanding and analysis to research.

Stay tuned – we’ll provide a closer look at some of those opportunities for better research (and reprints upon request) when the AMA publishes its report this fall.

Practical Statistics vs. Theoretical Statistics

Friday, April 9th, 2010

If something works and it keeps on working but you don’t know exactly why it works, what would you do?  Our view is that you should keep doing it.  Not everyone agrees with us.  The American Association of Public Opinion Research (AAPOR) convened a task force to study online survey panels, and released their report last month (we posted a summary of findings last week).  To us, the most jarring statement in the report was this:

“There currently is no generally accepted theoretical basis from which to claim that survey results using samples from nonprobability online panels are projectable to the general population.”

Even with careful statistical weighting based on demographics, known biases, propensity to be online and partake in surveys, and so on, the report concludes that online panels should not be used to estimate population parameters.  Why?  Not because this method doesn’t work (in many cases it does) but because there is no statistical theory to explain why it works, in contrast to probability sampling, for which there is solid theory explaining why it works.

How Good Are Online Survey Panels?

Thursday, April 1st, 2010

Ten years ago, surveys through online panels were rare.  Mostly we conducted telephone surveys.  Today it is the other way around.  With online survey panels being a $2 billion industry in the U.S., there is now a wealth of comparative data to measure and assess the implications of using online surveys as a substitute for phone surveys.

The American Association of Public Opinion Research (AAPOR) convened a task force in the fall of 2008 to study online survey panels, and they have just released their report.  It summarizes issues related to recruitment, panel maintenance, post-survey statistical adjustments, validity, and reliability.

Here is a summary of their conclusions and recommendations (quoted verbatim): (more…)

How to Conduct a Telephone Survey for Gold Standard Research

Thursday, February 25th, 2010

Telephone surveys are still considered the gold standard for rigorous public opinion polling and market research.  The reason is that virtually every household in the U.S. can be reached by telephone, and therefore we have careful methods of determining the probability that any individual person is included in a sample to be surveyed.  Knowing this probability is at the core of statistical inference, which makes mathematical purists very happy.

Here are the steps involved in conducting a rigorous “gold standard” telephone survey of the U.S. population: (more…)

Recent Findings on Phone vs. Online Surveys

Friday, February 5th, 2010

A research article the Winter 2009 issue of Public Opinion Quarterly provided some useful comparisons of data quality between phone surveys and various types of online surveys.  The findings are based on an experiment that fielded identical questionnaires via three survey modes, and, not surprisingly, there are strengths and weaknesses to each type of survey.

As reflected in the table above, the article is rather technical.  But there are two key summary points worth learning from the study: (more…)

Top Trends of the Decade: Looking Back

Thursday, December 31st, 2009

As an industry driven by data and information, market research and public opinion polling has seen dramatic changes in the last ten years and will no doubt change quickly and in big ways during the next ten.

Looking back, here are what we consider to be the five biggest changes that shaped current challenges faced by market research and opinion polling: (more…)

People Don’t Lie on Surveys

Thursday, December 24th, 2009

For some reason I’m always a little surprised that people tell the truth on surveys.  I like to think of my “healthy skepticism” as a professional asset, because it forces us to check and double check, corroborate and triangulate.  Before we commit to the findings of a research effort, we need to feel 100% sure we’re right and that our findings are based on solid data.

There Are Too Many Surveys

Thursday, November 12th, 2009

You might think that a research firm specializing in surveys would be glad to see a world in which customer feedback surveys are everywhere.  Not so.  I take part in a lot of webinars, and unfortunately I am asked to complete a survey (at least one) every time I attend.  Some websites ask me to evaluate my experience every time I go there.  Some companies ask me to evaluate my customer service call every time I call with a question or complaint.  The companies asking me to complete these surveys are convinced by pitches like this:  “The real power of [our survey tool] can only be unlocked through a commitment to continuous listening.  Listening to your visitors is truly a process, not an event. Continuous surveying can help you to establish benchmarks and trend your performance on key metrics.” (more…)

Mistakes to Avoid when Conducting a Public Relations Survey

Surveys and polls can be powerful tools to understand what people are thinking and doing, and they can provide good data for public relations efforts and community outreach.  Unfortunately they can also be gimmicks, which erodes trust in polling and in the organizations sponsoring them.
