    Any good marketing/analytics system cuts through the nonsense, and in short order.When I'm called in to analyze a business, there is usually a problem, and there are differing opinions about the problem. Most often, sales are in decline, or sales are not growing at a rate that meets corporate expectations. So I'm asked "why"? Why aren't sales meeting expectations?Remember the forecasting tool I discussed? The forecasting tool is an awful lot more than just a forecasting tool. It is part of a system designed to highlight weaknesses. I can quickly see if customer acquisition is a problem (it…

    The true cost of electricity is difficult to pin down. That's because a number of inputs comprise it: the cost of fuel itself, the cost of production, as well as the cost of dealing with the damage that fuel does to the environment.

    The "comp segment analysis" is one of the two big pieces in my business system. Here, I get to quickly diagnose what is happening to a business.In this comp segment analysis, I analyze customers with exactly two in-store purchases and no other purchases in the past year. In other words, these are customers who are most likely to appreciate the in-store experience. If they are spending less in retail, then something is wrong.The table shows us that something is wrong ... in stores.I'm measuring subsequent twelve-month spend. First, look down the "Total" column. Retail customers are just as…

    Did you end up with a bunch of free U2 songs on your device, even if you have absolutely no interest in the band whatsoever (click here)?I know, I know, you are a marketer and you think Apple did something noble by paying U2 $$$ to give you access to free music. It's a "gift without purchase"! Unless you don't like U2. Then what do you think it is?The number one question I'm fielding here in late summer is this one ... "why, beyond our loyal customer base, are the rest of our customers defectingI see this, over and over and over again. Loyal customers largely hang in there ... while the…

  • Creating A Growth-Based Catalog Vendor Ecosystem

    Kevin Hillstrom
    10 Sep 2014 | 8:15 pm
    Several years ago, I got to the end of a contact strategy project. The EVP, an earnest and good person, looked at me and said, if I may paraphrase: "I don't want more profit, we already generate plenty of profit. That's good enough. I need to grow. I need market share. Why do you care more about profit than market share? Real marketers care about market share!"And with that, the two individuals I spoke with departed, sent me my check, and did not implement four weeks of hard work. I never heard from the company again.Catalogers are at a crossroads. There are two business models that folks…
  • Now It's Time To Negotiate With The Co-Ops, Dear Catalogers

    Remember yesterday's example (click here to remember the post)? You invest 8,500,000 catalogs with your printer, and with your co-op, in order to transform your business from a business that generates $2,500,000 of pre-tax profit on $50,000,000 in annual sales to a business that generates $55,950,000 in annual sales at break-even.It's time for you to have a heart-to-heart discussion with your vendor partners. Think about the co-ops, for instance. How much additional work do they have to do to put the last 100,000 of the 8,500,000 co-op catalogs in the mail? None. No additional work…

  • Using Analytics at the Ground Floor Sends Profits Through the Roof

    15 Sep 2014 | 6:45 am
    In today’s hyper-competitive global economy, it’s becoming increasingly difficult for companies to differentiate themselves by price or product. However, one distinction that every company has to its advantage is unique information about its customers that it’s able to act on. In business for more than 50 years, Jaeckle Distributors’ five locations provide flooring and countertops to customers in the Midwestern US. As the flooring and countertops industry has become increasingly commoditized, Jaeckle Distributors sought ways to use available information to help distinguish itself from…

    As consumers have more channel choices than ever before, the role of the physical store has become more important than ever for providing customers with effortless experiences and earning their loyalty. This helps explain why a growing number of retailers are increasingly analyzing data about customer behaviors, customer traffic patterns, inventory placement, and other information to gain a deeper understanding about customer preferences, merchandising placement, and employee performance to identify opportunities to strengthen the in-store customer experience – and bolster business…
  • A Beautiful Mind – How Data Visualization ‘Art’ Empowers, Inspires

    Good art hangs on walls; great art spurs conversation. Infographics are everywhere. So, too, are charts, graphs, maps and all manner of data visualizations used by companies to predict futures and make decisions. The problem? Many are created, circulated and re-circulated without any real impact. Employees look but aren’t engaged – visualizations hang on walls but don’t prompt discussion. Data Is Beautiful That’s the name of a compelling Reddit thread containing some of the best data visualizations created this year. All the usual suspects are here but there’s a…
  • Ask the Right Questions for Big Data ROI

    10 Sep 2014 | 5:55 am
    While companies may be accustomed to formulating analytics questions revolving around past performance, to get the most of out of big data, queries should link  tactical and strategic-level objectives. That’s the advice that John Lucker, principal and global advanced analytics modeling leader at Deloitte, points out in a recent TechRepublic article. Lucker describes these questions as “crunchy,” because they are key to generating meaningful answers for operations. For example, a chief marketing officer can ask for list of the company’s next 1,000 customers and information about how a…

    The flood of information about consumer behavior online can be a gold mine for marketing. Instead of launching mass media campaigns aimed at a broad demographic of people, it’s now possible to tailor an offer to a single consumer based upon his immediate needs. However, to take advantage of this opportunity, marketers must embrace a different business model, one that can be altered as fast as a consumer changes search terms or leaves a comment on a company’s Facebook page. That’s according to a new article from McKinsey & Company in which David Edelman, co-leader of McKinsey’s…

  • Detailed Cancer Rates by State and County from the CDC

    Morgan Robinson
    11 Sep 2014 | 9:11 am
    Cancer is one of the most common diseases in the United States: approximately 40 percent of all people will be diagnosed with some type of cancer during their lifetime. Many health agencies monitor cancer trends; among them is the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) program. SEER measures cancer incidence – the number of new cases diagnosed – as well as survival statistics and mortality. The newest data on PolicyMap is state and county cancer rates and cases, provided by SEER and CDC’s National Program of Cancer Registries (NPCR). The rates…

  • Lyme Disease Data Now On PolicyMap

    8 Sep 2014 | 8:09 am
    The Tick… in PolicyMap colors! I like to go hiking. Whenever I get the chance, I go for a walk through the Wissahickon woods in northwestern Philadelphia. Deep in the forest, you forget you’re in a city. It’s wonderful. Except, if you’re not careful, it’s kind of dangerous. Ticks carrying Lyme disease are all over some parts of the country, and we’ve just loaded data from the CDC showing where Lyme disease is most prevalent. Rarely do we find a map showing such a clear geographic trend. In the Mid-Atlantic, New England, and upper Midwest, Lyme disease is a big issue. Four of…
  • Food Insecurity Data In the News

    From Philadelphia to Ohio to South Dakota, food insecurity has been a hot topic in the news since the United States Department of Agriculture (USDA) released its Household Food Security in the United States in 2013 report. For those of you wondering what food insecurity is, it refers to the USDA’s measure of lack of access, at times, to enough food for an active, healthy lifestyle for all household members and limited or uncertain availability of nutritionally adequate foods. In light of the focus on this important topic right now, we wanted to take the opportunity to make sure our…
  • If You’re a Student Reading This Post, You Should Be a PolicyMap Intern

    Bernie Langer
    28 Aug 2014 | 2:57 pm
    PolicyMap is looking for interns. People who like data, like maps, and aren’t afraid of a little bit of coding. Maybe know a little SQL, maybe worked a bit with Access, maybe excel at Excel. Ever look at a map, and then realize you’ve lost the last half hour of your life? Then consider being a PolicyMap intern. As soon as they arrive, our interns are part of the data team, discussing new indicators, offering input, processing data, and writing blog posts. They’re given guidance, but also independence to complete projects that interest them, and when they’re done, the data goes online.

  • Using Reddit's JSON API to analyze post popularity

    David Smith
    15 Sep 2014 | 11:01 am
    Graduate student Clay McLeod decided to find out what makes a post on the social-sharing site Reddit popular. These are the questions he seeks to answer: What’s in a post? Reddit pulls in around 115 million unique visitors each month, amassing a staggering 5 billion page views per month. For a long time, I’ve wondered what factors draw people to certain Reddit posts while shunning others - does it have to do with the time of day a post is submitted? Do certain users have a monopoly on the most viewed posts? What about text posts vs. links? Reddit provides a JSON API to download Reddit…

  • Google uses R to calculate ROI on advertising campaigns

    David Smith
    12 Sep 2014 | 11:25 am
    Google has just released a new package for R: CausalImpact. Amongst many other things, this package allows Google to resolve the classical conundrum: how can we asses the impact of an intervention (for example, the effect of an advertising campaign on website clicks) when we can't know what would have happened if we hadn't run the campaign? For a marketer, the worry is that the spike in clicks was partially or wholly the result of something unrelated (say, a general increase in web traffic) rather than your campaign. The CausalImpact package uses Bayesian structural time-series…
