Search Engine Optimization

Future Internet Book, 2021

manner in which people obtain information. Soon after the introduction of the WWW, it was evident
that traditional browsing was totally insufficient for internet users to locate the information that
interests them. This need was covered with the development of search engines. Today, search engines
play one of the most important roles in disseminating content. Search engine optimization (SEO) is a
collection of strategies that improves a website’s presence and visibility on a search engine’s results
page (SERP). In other words, the higher and more frequently a site appears in search results, the more
visitors it will receive through the use of search engines. The importance of SEO can be understood by
the fact that many web sites today receive the majority of their web traffic through a search engine’s
organic results.
The methods that SEO includes can be divided into four major categories: keyword
research/selection, search engine indexing, on-page optimization, and off-page optimization. On-page
optimization includes the management of all factors associated directly with someone’s website (e.g.,
keywords, appropriate content, and internal link structure), while off-page optimization includes all
the efforts made away from the website such as link building or social signal strategy. Undeniably, the
world of search engine optimization has changed and evolved drastically over the years with a shift
away from traditional ranking factors towards deeper analysis, and factors such as quality, multi-form
content, and social signals. However, even though SEO has changed a lot, it remains an important part
of any digital marketing strategy.
This special issue is soliciting theoretical and case studies contributions, discussing and treating
challenges, state-of-the-art technology, and solutions on search engine optimization, including, but not
limited to, the following themes related to SEO: Theory of SEO, different types of SEO, SEO criteria
evaluation, search engines’ algorithms, social media and SEO, SEO applications in various industries,
SEO in media web sites, etc. Through invited and open call submissions, a total of five excellent articles
have been accepted, following a rigorous review process that required a minimum of three reviews
and at least one revision round for each paper.

The Politicization of Selfie Journalism: An Empirical Study to Parliamentary Elections

by Andreas Veglis and Theodora A . Maniou

Mehdi Khosrow-Pour (Ed) Journalism and Ethics: Breakthroughs in Research and Practice, 2019

This paper identifies the specific characteristics of Selfie Journalism in political reporting. Based on both quantitative and qualitative research, the study analyses these characteristics in the period of parliamentary elections of 2016 in Cyprus. The aim of the study is dual: first, to examine the extensive use of Selfie Journalism by candidates themselves in political campaigning and, secondly, to examine the impact of this phenomenon upon the media and, in turn, media engagement in such political tactics. The greater scope of this study evolves around the argument that Selfie Journalism, as a new species of participatory journalism, has penetrated the media in an effort to attract larger audiences.

The article will address both the theoretical and practical issues related to the design and implementation of SEO and also will cover previous research done on this topic. In order to give a better understanding of the importance of SEO in the current state of the Internet and in information search, basic knowledge of how search engines operate along with their recent updates will also be provided. The development of World Wide Web (Web 2.0) along with the growth of search engines over the last decade has brought significant changes in web content. In this context, we will see how SEO has evolved over the years since mid 90's when it first emerged. Nowadays, social media and social signals have increasingly become one of the many factors search engines take seriously into account, which is another issue that this article will address.

A lot of progress has been conducted during the last decades in Information and Communication Technologies, which is also reflected in social media. The proposed models take advantage of the latest media technologies for the augmentation of user-interaction and contribution experience in multiple levels. Features of the suggested agent and multi-agent approaches are discussed and elaborated through the prism of social computing, social media analytics and intelligence, resulting to a sophisticated communication mediator between users and social groups. In addition, enhanced user engagement and collaboration are considered in terms of rich media experience and augmented reality, semantic interaction services, intelligent content processing and management automation over interoperable multiplatform environments. Social media cooperation and integration is envisioned towards the realization of Web 3.0 and beyond, as the main chapter contribution.

Το πρωτοποριακό αυτό εγχειρίδιο είναι απαραίτητο να διαβαστεί από δημοσιογράφους που διαχειρίζονται όλων των τύπων περιεχόμενο που έχει δημιουργηθεί στο διαδίκτυο από χρήστες (User Generated Content-UGC).» - Wilfried Ruetten, Διευθυντής, (Ευρωπαϊκό Κέντρο Δημοσιογραφίας (The European Journalism Centre -EJC)
«Μια ακριβής πληροφορία μπορεί να αποτελέσει βοήθεια ακόμα και για τη σωτηρία μιας ζωής κατά τη διάρκεια μιας ανθρωπιστικής κρίσης, αλλά οι συνθήκες μέσα στις οποίες τέτοιες κρίσεις αναδύονται είναι συνήθως οι δυσκολότερε ςόσον αφορά στη συγκέντρωση αξιόπιστων πληροφοριών. Το βιβλίο αυτό θα βοηθήσει όχι μόνο τους δημοσιογράφους αλλά και οποιονδήποτε δουλεύει επί τόπου σε ανθρωπιστικές καταστάσεις να επιβεβαιώσει τα γεγονότα που συμβαίνουν στο πεδίο δράσης.» - William Spindler, Εκπρόσωπος, Ύπατη Αρμοστεία του ΟΗΕ για τους Πρόσφυγες (The United Nations High Commissioner for Refugees -UNHCR)
«Το εγχειρίδιο αυτό θα είναι απαραίτητο σε δημοσιογράφους που καλύπτουν συγκρούσεις ανάμεσα σε θρησκείες ή εθνότητες, βοηθώντας στη διεξαγωγή του ρεπορτάζ με έναν πιο ισορροπημένο, διάφανο και ακριβή τρόπο και εντέλει, βοηθώντας στην εκτόνωση των όποιων εντάσεων μεταξύ και εντός των κοινοτήτων.» - Matthew Hodes, Διευθυντής, Συμμαχία των Πολιτισμών του ΟΗΕ (The United Nations Alliance of Civilizations -UNAOC)
«Σε αυτούς τους καιρούς, το να γνωρίζει κάποιος τι είναι αληθινό και πώς να επιβεβαιώνει τις ειδήσεις και άλλου είδους πληροφορίες, είναι βασικό.

«Η σωστή λήψη των γεγονότων αποτελεί μια θεμελιώδη αρχή της δημοσιογραφίας, αλλά τα μέσα ενημέρωσης αγωνίζονται να μείνουν ιδεολογικά σωστά όταν συμβαίνει μια μεγάλη έκτακτη είδηση. Το εγχειρίδιο αυτό βοηθάει τους δημιουργούς των ειδήσεων (newsmakers) να μείνουν πιστοί στην αλήθεια -ακόμα και αν οι εικασίες στο διαδίκτυο είναι ανεξέλεγκτες.» - Aidan White, Διευθυντής, Δημοσιογραφικό Δίκτυο για τη Δεοντολογία (The Ethical Journalism Network -EJN)

This mainly happens because of the human need to produce more energy, so it can be used in services and in production. Obviously WWW is part of the problem since it is supported by a large number of data centers, which main function is to provide guaranteed reliable service, security and connectivity to the rest of the Internet via a high-capacity backbone. Data centers consume significant amounts of energy. According to News York Times data centers in the United States consume more than 1 billion watts of electricity each year. The aim of this book is to study possible methods that can be applied to media websites in order to reduce power consumption and to educate internet users on environmental issues. Some of the issues that the study addresses are: Whether the servers are powered by renewable sources of energy, the ecological graphic design of the websites, and the existence of energy saving mode, the prevention of printing articles, whether newspapers inform their readers about environmental issues and the interdependence or participation in actions related to environment protection.

Audiovisual Hypermedia in the Semantic Web

Interactive media authoring and sharing technologies are currently being launched, bringing forward new ways of audiovisual (AV) content exchange. Web documentaries (web-docs) and hypermedia have appeared as a natural extension of filmed documentaries and digital TV, inheriting also some of their advantages. Narrative documentaries adopt AV mediated communication mechanisms that humans have been accustomed to be informed and communicate with each other, so that they are more informative and vivid compared to other documents (books, web-pages, multimedia, etc.). Thus, AV-documentaries and especially web-docs can be more easily distributed and attended from most ages and social groups (Dimoulas, Kalliris, Chatzara, Tsipas, & Papanikolaou, 2014a; Kotsakis, Kalliris & Dimoulas, 2012; Veglis, Dimoulas & Kalliris, 2014). Moreover, the continuous evolution of the computing power and the digital storage media, favor digital video production and distribution. This is also fuelled by the increased network speed, the efficiency of the contemporary compression algorithms and the continuous decrease of the corresponding costs (Kotsakis et al., 2012; Dimoulas, Kalliris & Veglis, 2014). High quality AV capturing equipment is currently available at low cost and size as part of smart phones and other mobile computing terminals with inherent networking capabilities, allowing easy AV-content production, contribution and sharing (Atzori, Delgado & Giusto, 2012; Dimoulas et al., 2014a; 2014b; Veglis et al. 2014). In this context, more and more users are involved in the AV production and consumption chain, so that creative experience and AV media culture are cultivated. Nevertheless, AV media related achievements are still far from the progress that has been made in textual information management during the outspread of social media and Web 2.0 services.

Interactive services have also been introduced into the AV production industry, aiming at augmenting human-machine interaction (HMI). AV content is enhanced in functional and informative level, further stimulating users to actively participate in arousing interactive scenarios. While the transition from Web 2.0 to Web 3.0 is ongoing, intelligent AV-content processing and management services are pursued, facilitating users’ participation on semantically enhanced hypermedia authoring and collaborative multichannel media publishing. Although hypermedia technologies are rapidly evolving, there are still open challenges regarding upcoming semantic web services (De Bra, Freyne, & Berkovsky, 2013; Dimoulas et al., 2014a; 2014b; Kanellopoulos, 2012; Monaghan, Handschuh, & O'Sullivan, 2011; Veglis et al. 2014). The current article examines current trends and future perspectives of AV hypermedia (AVH), considering all the forms of non-linear storytelling (web-docs, multichannel media publishing, etc.) and the associated hypermedia authoring counterparts. Background is presented providing basic definitions, involved technology, achieved progress and limitations. Recommendations and future research direction are then stated, aiming at serving a two-folded target. Firstly, to present new, user-friendly forms of collaborative creativity, hypermedia authoring and storytelling that current technology allows to be successfully deployed. Secondly, to suggest innovative adaptation mechanisms that can be utilized in both the AVH production and consumption ends, allowing for intelligent media management and augmented semantic interaction services to be launched. In this context, the importance of AVH toward the transition to the Web 3.0 era is revealed.

Cloud computing users have the flexibility to enjoy media content independently of time and space. Multimedia cloud computing encompasses technology, multimedia data and community contribution, offering augmented multimodal interaction and advanced processing services to the users. Mobile multimedia resources can now be accessed through the cloud practically at anytime and from anywhere, facing contemporary demands for information access and process, thus perfectly matching to the nature of news media. Such features are very favorable in online journalism and specifically in news reporting services. The current book chapter aims at presenting technological and application-oriented trends in cloud-based mobile news reporting both at journalists’ (news producers) and users’ (news consumers) sides. Future and emerging perspectives, such as ubiquitous and pervasive computing, incorporating context and location aware services in semantic interaction modes, are also described from the news-reporting point of view.

Online Newspapers in Greece: the Evolution of a Digital Genre

At an era of great disillusionment about the quality of journalism produced by traditional media,... more At an era of great disillusionment about the quality of journalism produced by traditional media, the Internet appeared as a revolutionary tool in the formation of the public sphere and culture at large. Its proponents argue that the Internet’s nature is characterized by a freedom of activity and thought. Due to the particular attributes of online news provided by technology and low publishing costs, thousands of people and organizations are allowed to self-publish and millions more have the opportunity to read alternative content outside the mainstream. However, there is increased evidence that large corporate portals and media trademarks are dominating online attention for news.
Greek people are not enthusiastic consumers of online news, firstly due to decreased interest in public affairs, and secondly due to low adoption rates of new technologies in their everyday lives. So what is the added value offered by greek online editions that would make a reluctant population to eventually turn to digital news? Drawing upon genre theory, the paper attempts to trace the evolution of the greek online newspaper. The websites of Ethnos, Ta Nea and Eleuferotypia are put into scrutiny in order to investigate: (a) how have greek newspaper websites evolved over time, and (b) how has the rationale of the online editions been shaped since their inception.
