Transcript of "Ebriks-Estimate the investment in media"

  1. 1. Market Mix ModellingEstimate the effectiveness of investment in media
  2. 2. Agenda• Business application of Marketing Mix modelling• A case study• Strengths and weaknesses• Brief introduction to more advanced approaches: pooled regressions and structural equations
  3. 3. Making BP’s media dollars work harder• “Mindshare helped BP to make the most of their media investments across the many states of the USA.”• “BP engaged Mindshare to develop enhanced media investment strategies to maximise sales and boost revenue performance.”• “Drivers of performance were quantified (e.g. media, promotions, distribution, competitor effects) in seven USA states, over three years”• “Return on investment figures were calculated - both short and long term - for 40 campaigns.”
  4. 4. Marketing Mix modelling• Statistical methods applied to measure the impact of media investments, promotional activities and price tactics on sales or brand awareness• Used to assist and implement a marketing strategy by measuring: – Effectiveness: contribution of marketing activities to sales – Efficiency: short term and long term Return-On- Investment of marketing spend – Price elasticity – Impact of competitors
  5. 5. MMM How does it work?• A statistical model is estimated on historical data with sales as a dependent variable and list of explanatory variables as marketing activities, price, seasonality and macro factors• The simplest and broadly used model is linear regression: Salest    1  var 1t   2  var 2t  ...   t• The output of the model is then used to carry out further analysis like media effectiveness, ROI and price elasticity and to simulate what-if scenarios
  6. 6. Factors that could drive sales Advertising Promotions Competition TV Sponsorships Seasonality Radio Events Weather Print Price Economic Outdoor Adv quality Demographic Internet Distribution Industry data MerchandisingSalest    1  var   2  var  ...   t 1 t t 2 Sales
  7. 7. MMM project process Set out objectives Data preparation -Define scope •Collect data -Discuss data •Validate, harmonize availability and consolidate data-Design data-warehouse •Present exploratory analysis to client Presentation Model development •Interpretation of •Estimation results •Diagnostics •Learning and •Calculate ROIs, Price recommendations elasticity and response curves
  8. 8. Case study• An energy company SPetrol wants to evaluate the advertising investments of its retail business in the US from 2001 until 2004.• Client’s questions: • How much have we made through advertising? • What is the return on investments of our media activities? • Which marketing drivers have had the greatest effect? • What’s the influence of price on our sales? • Are we optimally allocating our budget across products ?
  9. 9. Target variable
  10. 10. Advertising data• The performance of TV and radio advertising is expressed in terms of Gross Rating Points (GRPs) . A rating point is a percentage of the potential audience and GRPs measure the total of all rating points during and advertising campaign. – GRPs (%) = Reach * Frequency – Example: Let’s assume a commercial is broadcasted two times on TV 1st time on air 2st time on air GRPs 25% of target 32% of target 57% televisions are tuned in televisions are tuned in
  11. 11. Advertising data• Spetrol has deployed 5 TV campaigns over the sample with a total expenditure of 300 million $• Each campaign lasted from 4 to 8 weeks• Is there any relationship between sales and TV advertising?
  12. 12. Carry over effect of TV
  13. 13. Carry over effect of TV• The exposure to TV advertising builds awareness, resulting in sales.• ADStock allows the inclusion of lagged and non linear effects ADStockt ( )  GRPt    ADStockt 1 0  1• Alpha is estimated iteratively using least squares. The estimate is then validated by media planners

  24. 24. Estimated factors contribution to sales Fitted Salest = estimated Intercept = 167,412 Can be interpreted as Brand Equity: •Volume generated in absence of any marketing activity •Indicator of the strength of the brand and users’ loyalty

  35. 35. Price elasticity• Assumption: constant elasticity across the sample which implies a linear relation between volume and price• By using the coefficient of the regression, it is possible to derive an estimate for price elasticity: – Price coefficient = -12631 – Average price = 1.51 $ – Average volume sales = 154,000 Gallons Avg Pr ice A 10% drop in price Elasticity  * coeff  0.12 increases sales by 1.2% AvgSales

Estimated through nonInelastic (<1): Demand is not sensitive to price changes linear regressions
  37. 37. Client’s questionsHow much have we made through advertising? • 1 billion $ driven by TV • 500 million $ due to radio • 200 million $ generated by Outdoor and promotional activities Investments in media generated 1.7 billion $ in revenue
  38. 38. Client’s questionsWhat is the return on investments of our media activities? For each dollar invested in TV you get 3.5 dollars back
  39. 39. Client’s questionsWhat’s the influence of price on our sales? A 10% drop in price increases sales by 1.2%
  40. 40. Are we optimally allocating our budget across products ? Maximum Optimal GRPs Marginal Return Over Optimal GRPs Point of Saturation Sub –Optimal GRPs Maximum Average Return Invest more in Radio and less in OOH

Weekly GRPs Diminishing Returns is the point were spending additional GRPs does not results in additional Simultaneous Effect sales. Carry Over Effect (Ad Stock) relates to theVolume residual effect of an ad. When all the components are layered on Base Base/Seasonal TV/Radio/Print Direct Marketing Rates/Promotions sales, it is clear what drivers contribute to sales Time and when and their Simultaneous Effect.
  42. 42. Pros and cons• Simple and intuitive • Correlation doesn’t imply• The outcome is backed by causality qualitative expertise and in • Risk of spurious regressions field research especially when modelling• Constructive way of running in levels different scenarios and • Model highly depends on evaluating past variables chosen performance • Poor in forecasting• Better with granular data• Very successful method – high turnover
  43. 43. Spurious statistics • A high correlation between sales and TV could mean:Sales Media – Either media causes sales – or sales causes media – or a third variable causes Income both sales and TV What is the truth?
  44. 44. Non sense correlations• Some spurious • On the other hand, a correlations: low correlation doesn’t – death rate and rule out the possibility proportion of marriages of a strong relation: Corr = 0.95 Corr = 0.0 – National income and sunspots Corr = 0.91 – Inflation rate and accumulation of annual rainfall •Correlations must support a theory •Calculate correlations both in levels and differences •Always look at scatter plots
  45. 45. What variables should have been included?
  46. 46. New media• Digital Marketing – Display Marketing – Search Engine Marketing (SEO & PPC) – Affiliate Marketing – Mobile Marketing – Social Media
  47. 47. New media• Data availability – Impressions – Clicks – Post event activity – Bespoke engagement metrics• Example of a tracking centre: – Double-click

  51. 51. How advertising effects consumers?Understanding:– the process by which advertising affects consumers– How the effects of advertising are spread over time– The role of different media– The role of competitors
  52. 52. The purchase funnel• A basic process that leads to the purchase of Awareness a product consists in: – Awareness – costumer is aware of the existence of a product Consideration – Consideration – actively expressing an interest in the company – Purchase Purchase
  53. 53. Working on survey data• A sample of the target audience is interviewed about brand awareness, consideration and choice• Research agencies provide awareness, consideration and purchase time series in % terms – i.e. A purchase of 10% means that 10 out of 100 interviewed people purchased the product
  54. 54. Testing the purchase funnelAwareness Consideration Purchase Advertising first exercise its influence on awareness. Via awareness there is an effect on Media consideration which drives the consumer to purchase
  55. 55. Testing the purchase funnel • Awarenesst=c11+c12*TVt+c13*radiot+c14*OOHt+error1t • Considerationt = b1*awarenesst + c21 + error2t • Purchaset = b3*Considerationt + b2*Awareness +c31 + error3t a1,a2,a3 must be insignificant to confirm theory Const  1  a1  a2   Awart   c11 c12 c13 c14      1t  b 1  a3    Const   c21 0 0 0    TVt     1      Radiot   2 t  b2  b3 1   Purcht  c31 0     0  OOH   3t  0     t 
