Geotargeting in Programmatic

A study of digital campaigns show traffic targeting 10 DMAs mapped well to those geographies.  Exceptions are some datacenter traffic, and micro-targeting.  Zooming in, local “freckles” of hundreds of IP addresses were shown to have the same geo-location, and not the exact user GPS location — desktop, mobile, and tablet shared the same clusters of geo-locations.

Bots vs Humans on a Map

Geographic distribution of human and bot traffic in internet advertising is generally comparable when viewed on a map.  Mass fraud commited out of large datacenters is the one exception.  Close examination of the bot traffic does show some unlikely geographies but most is likely sourced from malware sitting on a system attached to a legitimate IP address location.

The New WMD’s

The New WMD’s

WMD? Is Cathy O’Neil creating a hysterical media frenzy so she can sell more copies of “Weapons of Math Destruction“, or is she sincerely onto something?

Well, if the word “math” in your book title, it’s best to do anything you can to get some other relevant attention! Anything! Foment hysteria? Well, worth a try… But we’re into something more than just fomenting hysteria here. It’s a radical book, but fair. And well written….

Models I've Built

Predictive Models I’ve Built

While at Epsilon, from 2000-2016, and at Time Inc. prior to that, my primary use of data was to create analyses and predictive models for client applications.  I also created predictive models that became data products in their own right, many of which are still sold to Epsilon clients today.

Generally working with customer file data using SAS and R, I created the following types of modeling solutions:

  1. Likelihood to Pay on a Marketing Offer – Predict the likelihood of payment and non-payment using ensemble modeling techniques
  2. Response Optimization – Enable optimal business results in client marketing campaigns through response models
  3. Segmentation – Used nearest neighbor and hierarchical segmentation techniques to segment the population into categories, or personas
  4. Prospect Models – Predict prospects that look most likely to exhibit a specific behavior, such as, response, pay, or product purchase
  5. Cross-Sell Models – Response models using customer transactional data to predict likelihood to respond to a new product offer
  6. Product Optimization – Given the likelihood of response, predict which product will be most profitable to offer to an existing customer.
  7. Area-Level Data Imputation – Impute missing data values using geographic roll-ups to enable complete data set coverage
  8. Propensity Models – Use census-balanced weighting to model look-alikes to self-reported consumer behaviors
  9. Econometric Models – Predict estimates for household characteristics such as income, net worth, and home value, applied as census-balanced scores across the US market
  10. Area-level Models – Predict geographies with populations most likeyl to exhibit an interest or purchase behavior

 

Data I've Worked With

Data I’ve Worked With

Aside

Most recently I worked on ad fraud detection using browser data.  Prior to that, I was responsible for Epsilon’s Analytical Data Assets team.  In this role I was tasked with analytic product development based on both Epsilon and 3rd party data.  While at Epsilon, from 2000-2016, my primary use of data has been to create analyses and predictive models for client applications.

I’ve worked with the following types of data:

  1. JSON Browser Data – Developed python code base to read and analyze browser session data containing indicators of potential human or ad fraud.
  2. Compiled Consumer Data – Household characteristics such as age, income, home ownership, and purchase transactions primarily on Epsilon’s TotalSource Plus file containing thousands of data points on 160MM US households.
  3. Consumer Self-Reported Data – Self-reported warranty and survey data relating to interests, purchases, and ailments (for example, interest in gardening, shops at Walmart, and suffers from diabetes), primarily from Epsilon’s Target Source database of over 40MM US households.
  4. Consumer Transactional Data – Bank data relating to credit and debit card line items summarized by merchant and merchant category by month, primarily Epsilon’s Market View data.
  5. Credit Data – Consumer credit line and credit inquiry data from Credit Bureaus
  6. Web Data – Email and digital data streams for web analytic analysis
  7. Syndicated Market Research Data – Census-balanced self-reported consumer research data, primarily the MRI syndicated survey research file.
  8. Business Firmagraphic Data – Characteristics and contacts associated with business entities
  9. Aggregated Credit Data – Credit bureau information aggregated at a zip+4 level
  10. US Census Data – Typically compiled and resold by companies such as, Epsilon and others
  11. Customer Relationship Management Data – Client specific transactional data in various industries (publishing, travel, financial)
  12. Dimagi CommCare – Contact and Case data associated with Covid-19 pandemic in NY State
