Causal Inference in the Presence of Interference in Sponsored Search Advertising
Causal Inference in the Presence of Interference in Sponsored Search Advertising Razieh Nabi∗ Joel Pfeiffer Murat Ali Bayir Johns Hopkins University Microsoft Bing Ads Microsoft Bing Ads [email protected] [email protected] [email protected] Denis Charles Emre Kıcıman Microsoft Bing Ads Microsoft Research [email protected] [email protected] Abstract In classical causal inference, inferring cause-effect relations from data relies on the assumption that units are independent and identically distributed. This assumption is violated in settings where units are related through a network of dependencies. An example of such a setting is ad placement in sponsored search advertising, where the clickability of a particular ad is potentially influenced by where it is placed and where other ads are placed on the search result page. In such scenarios, confounding arises due to not only the individual ad-level covariates but also the placements and covariates of other ads in the system. In this paper, we leverage the language of causal inference in the presence of interference to model interactions among the ads. Quantification of such interactions allows us to better understand the click behavior of users, which in turn impacts the revenue of the host search engine and enhances user satisfaction. We illustrate the utility of our formalization through experiments carried out on the ad placement system of the Bing search engine. 1 Introduction In recent years, advertisers have increasingly shifted their ad expenditures online. One of the most effective platforms for online advertising is search engine result pages. Given a user query, the search engine allocates a few ad slots (e.g., above or below its organic search results) and runs an auction among advertisers who are bidding and competing for these slots. -
Understanding Attention Metrics
Understanding Attention Metrics sponsored by: 01 introduction For years and years we’ve been told that if the click isn’t on its deathbed, it should be shivved to death immediately. While early display ads in the mid-90s could boast CTRs above 40%, the likely number you’ll see attached to a campaign these days is below 0.1%. But for some reason, even in 2015, click-through rate remains as vital to digital ad measurement although its importance is widely ridiculed. Reliance on the click means delivering unfathomable amounts of ad impressions to users, which has hyper-inflated the value of the pageview. This has led to a broken advertising system that rewards quantity over quality. Instead of building audiences, digital publishers are chasing traffic, trying to lure users to sites via “clickbait” headlines where the user is assaulted with an array of intrusive ad units. The end effect is overwhelming, ineffective ads adjacent to increasingly shoddy content. However, the rise of digital video and viewability have injected linear TV measurement capabilities into the digital space. By including time in its calculation, viewability has opened a conversation into the value of user attention. It has introduced metrics with the potential to assist premium publishers in building attractive audiences; better quantify exposure for advertisers; and ultimately financially reward publishers with more engaged audiences. This is a new and fast developing area, but one where a little education can go a long way. In addition to describing current attention metrics, this playbook will dive into what you should look for in an advanced metrics partner and how to use these metrics in selling inventory and optimizing campaign performance. -

Introduction In 2013, native advertising galloped onto the scene like a masked hero, poised to hoist publishers atop a white horse, rescuing them from the twin menaces of programmatic advertising and sagging CPMs. But who’s really there when you peel back the mask? Native advertising is a murky business. Ad executives may not consider it advertising. Editorial departments certainly don’t consider it editorial. Even among its practitioners there is debate — is it a format or is it a function? Publishers who have invested in the studio model position native advertising as the perfect storm of context, creative capital and digital strategy. For platforms, it may be the same old banner advertising refitted for the social stream. Digiday created the WTF series to parse murky digital marketing concepts just like these.

Q. WANG the Semi-Structured Online Public Sphere in China
The Semi-Structured Online Public Sphere in China: Institutional Criteria and Political Functions By Qingning Wang The Degree of Doctor of Philosophy Submitted to University of East Anglia School of Politics, Philosophy, Language and Communication Studies April 2017 This copy of the thesis has been supplied on condition that anyone who consults it is understood to recognise that its copyright rests with the author and that use of any information derived there from must be in accordance with current UK Copyright Law. In addition, any quotation or extract must include full attribution. Word Count: 95629 1 Abstract This research analyses online political communication in China by applying Habermas’ public sphere theory as a normative framework. The three institutional criteria ( equality, problematization of unquestioned areas, and principally inclusive ) and two political functions ( expressional function and corresponding function ) stemming from the public sphere theory act as analytic lenses to analyse the power relations, expressions, languages, and interactions in the communications. By using three events as case studies, this research applies a combination of content and discourse analysis to study them. It argues that there is a semi-structured public sphere in China, in the sense that it is a sphere that shows both promise and limitations in terms of facilitating equal, inclusive, liberal and critical political communications in China. It can act as a normative space for Chinese net-users to communicate about their concerns, but is not powerful enough to put real pressure on government to achieve sustained changes at policy level. Equal and inclusive debates are facilitated as net-users are given equal rights to express their opinions, and these opinions are inclusively available online; but they are also limited since pre-existing status has not been dis-regarded. -

Chinese national law has required most online service providers to implement real-name registration since 2012. This article uses the real-name registration rules to illustrate the supremacy and limitations of the Network Authoritarian Model (NAM), an approach leveraging corporate resources for political surveillance and occasionally adopted by the Chinese party-state. By addressing the evolution of real-name registration rules in China, this article illustrates the party-state’s gradual efforts in both eliminating cyberspace anonymity and etching Chinese characteristics on the architecture of the Internet. -

OUTSOURCED AUTHORITARIANISM: THE COMMERCIALIZATION OF STATE CONTROL IN CHINESE MAYOR’S HOTLINES AND THE INTERNET-OPINION INDUSTRY by Rui Hou A thesis submitted to the Department of Sociology In conformity with the requirements for the degree of Doctor of Philosophy Queen’s University Kingston, Ontario, Canada August, 2020 Copyright ©Rui Hou, 2020 Abstract How is the market engaged in the grassroots governance of authoritarian China? My work addresses this question by exploring state-market collaborations in the industry of Internet control and the system of Mayor’s Hotline. Drawing on rich empirical evidence, including ethnographic observation, in-depth interviews, document analysis, my work finds that market actors are actively engaged in state control and government outsourcing is a critical mechanism promoting the state-market collaboration. I develop the concept of outsourced authoritarianism to describe the phenomena that authoritarian regimes rely on government outsourcing to incorporate private actors into the institutions of state control. My work detailed shows, by outsourcing the frontline control to private sectors, the tentacles of state control have touched a wider range of the social population. This finding challenges the traditional wisdom that authoritarian domination is monopolized by state actors and suggests a networked and multi-leveled understanding of authoritarian power. However, even though government outsourcing promotes the coordination between private actors and governments in the institutions of state control, it does not mean the profit motive of the market has been smoothly integrated into the control apparatus of the state. My evidence further demonstrates that outsourced authoritarianism also brings new governance problems. In both cases, the engagement of private actors proceeds through the mode of government outsourcing, which creates a dual-pressure structure under which frontline operators need to handle pressures from both the state and the market. -
