Who Owns Metrics?: Building a Bill of Rights for Online Advertisers

Edelman, Benjamin. “Who Owns Metrics?: Building a Bill of Rights for Online Advertisers.” Journal of Advertising Research 49, no. 4 (December 2009). (Adapted from Towards a Bill of Rights for Online Advertisers.)

I offer five rights to protect advertisers from increasingly powerful ad networks-avoiding fraudulent charges for services not rendered, guaranteeing data portability so advertisers get the best possible value, and assuring price transparency so advertisers know what they’re buying. I explain the need for these rights by presenting specific practices causing particular concern.

Personal Rapid Transport at Vectus, Ltd. (teaching materials)

Edelman, Benjamin. “Personal Rapid Transport at Vectus, Ltd.” Harvard Business School Case 910-010, November 2009. (Revised September 2010.) (Featured in Working Knowledge: Can Entrepreneurs Drive People Movers to Success?) (educator access at HBP. courtesy copy.)

Personal Rapid Transport (PRT) vehicles—often called “driverless taxis”—sought to combine the best characteristics of cars, taxis, and trains, while adding features unavailable in any existing transportation system. Like cars and taxis, PRT vehicles carried small groups—often just a single passenger—with no need to wait for a shared vehicle to arrive or for others to board. Yet PRT followed train systems in using an exclusive right of way that avoided delays from other traffic. Where would such systems be most useful? Could system designers successfully compete with well-established networks of trains, buses, cars, and roads?

The Dark Underbelly of Online Advertising

Edelman, Benjamin. “The Dark Underbelly of Online Advertising.” HBR Now. (November 17, 2009).

The Internet is sold to advertisers as a highly measurable medium that is the most efficient way to target exactly the right customers. But online advertising is also easily subverted–letting fraudsters claim advertising fees for work they did not actually do. The trickiest frauds deceive advertisers so effectively that measurements of ad effectiveness report the fraudsters as exceptionally productive and high quality, rather than revealing that their traffic was actually worthless. This is a quiet scandal. In a time of tightening ad budgets, losses to advertising fraud come straight from the bottom line–but savings can be equally dramatic. Here’s a look behind the veil–an explanation of ad practices that have cheated even the Web’s largest advertisers. Advertising scams take plenty of victims, both witting and not, but I offer strategies to help determined marketers protect themselves.

Deception in Post-Transaction Marketing Offers

Edelman, Benjamin. “Deception in Post-Transaction Marketing Offers.” U.S. Senate, Committee on Commerce, Science, & Transportation, November 2009.

I examine the consumer protection issues raised by post-transaction marketing offers. My key concerns:

  • Post‐transaction marketing offers systematically reach consumers in a time when consumers are particularly vulnerable. Post‐transaction offers feature deceptive designs that invite consumers to conclude, mistakenly, that the offers comes from the companies the consumers have chosen to frequent, and that the offers are a required part of the checkout process.
  • The automatic transfer of consumers’ payment information from a merchant to a post ‐ transaction marketer runs contrary to consumer expectations, and creates a heightened risk that consumers will “accept” financial obligations they did not intend to incur.
  • Disclosures fail to cure the deception created by post-transaction offers, their timing and formatting, and their automatic transfer of consumers’ payment information.
  • Straightforward remedies could protect consumers who have suffered unwanted charges, and could prevent further consumers from incurring similar charges.

eBay Partner Network (teaching materials) with Ian Larkin

Edelman, Benjamin, and Ian Larkin. “eBay Partner Network (A).” Harvard Business School Case 910-008, September 2009. (Revised March 2015.) (educator access at HBP. request a courtesy copy.)

eBay considers adjustments to the structure and rules of its affiliate marketing program, eBay Partner Network (ePN). In particular, eBay reevaluates affiliate compensation structure, the role of bonuses for especially productive affiliates, and the overall rationale for outsourcing online marketing efforts to independent affiliates. The case presents the history and development of ePN, ePN’s importance to eBay, and the mechanics of online affiliate marketing.

Deterring Online Advertising Fraud Through Optimal Payment in Arrears

Edelman, Benjamin. “Deterring Online Advertising Fraud Through Optimal Payment in Arrears.” Financial Cryptography and Data Security: Proceedings of the International Conference (September 2009). (Springer-Verlag Lecture Notes in Computer Science.) (Featured in Working Knowledge: Reducing Risk with Online Advertising.)

Online advertisers face substantial difficulty in selecting and supervising small advertising partners. Fraud can be well hidden, and limited reputation systems reduce accountability. But partners are not paid until after their work is complete, and advertisers can extend this delay both to improve detection of improper partner practices and to punish partners who turn out to be rule-breakers. I capture these relationships in a screening model with delayed payments and probabilistic delayed observation of agents’ types. I derive conditions in which an advertising principal can set its payment delay to deter rogue agents and to attract solely or primarily good-type agents. Through the savings from excluding rogue agents, the principal can increase its profits while offering increased payments to good-type agents. I estimate that a leading affiliate network could have invoked an optimal payment delay to eliminate 71% of fraud without decreasing profit.

Priced and Unpriced Online Markets

Edelman, Benjamin. “Priced and Unpriced Online Markets.” Journal of Economic Perspectives 23, no. 3 (Summer 2009): 21-36.

With forces both supporting and opposing zero prices, typical Internet-related activities–like surfing the web, web searches, and e-mail, along with behind-the-scenes practices like domain names and the allocation of IP (Internet Protocol) addresses–present a natural context to reevaluate our sense of the tradeoffs that arise between free and a positive price. In this piece, I offer a series of specific examples of resources offered without charge, for a positive price, or for a flat fee (“all-you-can-eat”). I conclude by assessing the characteristics that shape pricing structure for these resources.

Securing Online Advertising: Rustlers and Sheriffs in the New Wild West

Edelman, Benjamin. “Securing Online Advertising: Rustlers and Sheriffs in the New Wild West.” In Beautiful Security, edited by Andy Oram and John Viega. O’Reilly Media, Inc., 2009. (Korean translation.)

Read the news of recent computer security guffaws, and it’s striking how many problems stem from online advertising. Advertising is the bedrock of web sites that are provided without charge to end users, so advertising is everywhere. But advertising security gaps are equally widespread: from “malvertisement” banner ads pushing rogue anti-spyware software, to click fraud, to spyware and adware, the security lapses of online advertising are striking.

During the past five years, I have uncovered hundreds of online advertising scams defrauding thousands of users–not to mention all the web’s top merchants. This chapter summarizes some of what I’ve found–and what users and advertisers can do to protect themselves.

Windows Vista (teaching materials)

Edelman, Benjamin. “Windows Vista.” Harvard Business School Case 909-038, February 2009. (Revised December 2010.) (educator access at HBP. request a courtesy copy.)

Microsoft designs, modifies, publicizes, and distributes Windows Vista—against a backdrop of consumers already largely satisfied with their existing Windows XP systems. Microsoft must decide what features to include and what to drop, how to compete with its own installed base, and how to mobilize partners to offer Vista-compatible systems.
