Towards Active SEO 2
JISTEM - Journal of Information Systems and Technology Management Revista de Gestão da Tecnologia e Sistemas de Informação Vol. 9, No. 3, Sept/Dec., 2012, pp. 443-458 ISSN online: 1807-1775 DOI: 10.4301/S1807-17752012000300001 TOWARDS ACTIVE SEO (SEARCH ENGINE OPTIMIZATION) 2.0 Charles-Victor Boutet (im memoriam) Luc Quoniam William Samuel Ravatua Smith South University Toulon-Var - Ingémédia, France ____________________________________________________________________________ ABSTRACT In the age of writable web, new skills and new practices are appearing. In an environment that allows everyone to communicate information globally, internet referencing (or SEO) is a strategic discipline that aims to generate visibility, internet traffic and a maximum exploitation of sites publications. Often misperceived as a fraud, SEO has evolved to be a facilitating tool for anyone who wishes to reference their website with search engines. In this article we show that it is possible to achieve the first rank in search results of keywords that are very competitive. We show methods that are quick, sustainable and legal; while applying the principles of active SEO 2.0. This article also clarifies some working functions of search engines, some advanced referencing techniques (that are completely ethical and legal) and we lay the foundations for an in depth reflection on the qualities and advantages of these techniques. Keywords: Active SEO, Search Engine Optimization, SEO 2.0, search engines 1. INTRODUCTION With the Web 2.0 era and writable internet, opportunities related to internet referencing have increased; everyone can easily create their virtual territory consisting of one to thousands of sites, and practically all 2.0 territories are designed to be participatory so anyone can write and promote their sites. -

Building Secure and Reliable Systems
Building Secure & Reliable Systems Best Practices for Designing, Implementing and Maintaining Systems Compliments of Heather Adkins, Betsy Beyer, Paul Blankinship, Piotr Lewandowski, Ana Oprea & Adam Stubblefi eld Praise for Building Secure and Reliable Systems It is very hard to get practical advice on how to build and operate trustworthy infrastructure at the scale of billions of users. This book is the first to really capture the knowledge of some of the best security and reliability teams in the world, and while very few companies will need to operate at Google’s scale many engineers and operators can benefit from some of the hard-earned lessons on securing wide-flung distributed systems. This book is full of useful insights from cover to cover, and each example and anecdote is heavy with authenticity and the wisdom that comes from experimenting, failing and measuring real outcomes at scale. It is a must for anybody looking to build their systems the correct way from day one. —Alex Stamos, Director of the Stanford Internet Observatory and former CISO of Facebook and Yahoo This book is a rare treat for industry veterans and novices alike: instead of teaching information security as a discipline of its own, the authors offer hard-wrought and richly illustrated advice for building software and operations that actually stood the test of time. In doing so, they make a compelling case for reliability, usability, and security going hand-in-hand as the entirely inseparable underpinnings of good system design. —Michał Zalewski, VP of Security Engineering at Snap, Inc. and author of The Tangled Web and Silence on the Wire This is the “real world” that researchers talk about in their papers. -
Search Engines and Power: a Politics of Online (Mis-) Information
5/2/2020 Search Engines and Power: A Politics of Online (Mis-) Information Webology, Volume 5, Number 2, June, 2008 Table of Titles & Subject Authors Home Contents Index Index Search Engines and Power: A Politics of Online (Mis-) Information Elad Segev Research Institute for Law, Politics and Justice, Keele University, UK Email: e.segev (at) keele.ac.uk Received March 18, 2008; Accepted June 25, 2008 Abstract Media and communications have always been employed by dominant actors and played a crucial role in framing our knowledge and constructing certain orders. This paper examines the politics of search engines, suggesting that they increasingly become "authoritative" and popular information agents used by individuals, groups and governments to attain their position and shape the information order. Following the short evolution of search engines from small companies to global media corporations that commodify online information and control advertising spaces, this study brings attention to some of their important political, social, cultural and economic implications. This is indicated through their expanding operation and control over private and public informational spaces as well as through the structural bias of the information they attempt to organize. In particular, it is indicated that search engines are highly biased toward commercial and popular US- based content, supporting US-centric priorities and agendas. Consequently, it is suggested that together with their important role in "organizing the world's information" search engines -

Search Engine Bias and the Demise of Search Engine Utopianism
GOLDMAN: SEARCH ENGINE BIAS SEARCH ENGINE BIAS AND THE DEMISE OF SEARCH ENGINE UTOPIANISM ERIC GOLDMAN ABSTRACT Due to search engines' automated operations,people often assume that search engines display search results neutrally and without bias. However, this perception is mistaken. Like any other media company, search engines affirmatively control their users' experiences, which has the consequence of skewing search results (a phenomenon called "search engine bias'). Some commentators believe that search engine bias is a defect requiring legislative correction. Instead, this Essay argues that search engine bias is the beneficial consequence of search engines optimizing content for their users. The Essay further argues that the most problematic aspect of search engine bias, the "winner-take- all" effect caused by top placement in search results, will be mooted by emerging personalizedsearch technology.

Intellectual Terrorism and the Church: The Case of the Google Bomb The United States today could be considered to be in an information age. One sees such foreshadowed in the “future history” the novel entitled The Moon Is A Harsh Mistress where a particular computer became charged with administering the Moon. That computer named “Mike” was one with apparently a low sense of humor that favored practical jokes was found in the story to be self-aware and sentient.1 The main thrust of that story became that that same computer came to be appointed to lead a revolution.2 The science fiction example of The Moon Is A Harsh Mistress is perhaps a warning to today’s culture about how much trust should be placed in machines. To many of the characters in the story that computer was able to simulate a living being who acted as leader of the revolution. The computer itself made the decisions about how the revolu- tion went. With concerns over the preservation of documentary heritage in light of comput- erization concern can be had as to what is happening to that documentary heritage. -

IF SEARCH NEUTRALITY IS the ANSWER, WHAT's the QUESTION? Geoffrey A. Manne* Joshua D. Wright**
IF SEARCH NEUTRALITY IS THE ANSWER, WHAT'S THE QUESTION? Geoffrey A. Manne* Joshua D. Wright** In recent months a veritable legal and policy frenzy has erupted around Google generally, and more specifically concerning how its search activities should be regulated by government authorities throughout the world in the name of ensuring "search neutrality." Concerns with search engine bias have led to a menu of proposed regulatory reactions. Although the debate has focused upon possible remedies to the "problem" presented by a range of Google's business decisions, it has largely missed the predicate question of whether search engine bias is the product of market failure or otherwise generates significant economic or social harms meriting regulatory intervention in the first place. "Search neutrality" by its very name presupposes that mandatory neutrality or some imposition of restrictions on search engine bias is desirable, but it is an open question whether advocates of search neutrality have demonstrated that there is a problem necessitating any of the various prescribed remedies. This Article attempts to answer that question and evaluates both the economic and non-economic costs and benefits of search bias, as well as the solutions proposed to remedy * Lecturer in Law, Lewis & Clark Law School; Executive Director, International Center for Law & Economics. ** Professor, George Mason University School of Law and Department of Economics.
