Advertisers setting up search engine advertising campaigns for the first time need to place bids on keywords, but typically lack experience and data to determine ranks that maximize a keyword's profit (generally referred to as a cold-start problem). This article aims at solving the problem of bidding on keywords in newly set-up search engine advertising campaigns. We suggest that advertisers collect data from the Google Keyword Planner to obtain precise estimates of the percentage increases in prices per click and clickthrough rates, which are needed to calculate optimal bids (exact approach). Together with the profit contribution per conversion and the conversion rate, the advertiser might then set bids that maximize profit. In case advertisers cannot afford to collect the required data, we suggest two proxy approaches and evaluate their performance using the exact approach as a benchmark. The empirical study shows that both proxy approaches perform reasonably well-the easier approach to implement (proxy 2) sometimes performs even better than the more sophisticated one (proxy 1). As a consequence, advertisers might just use this very simple proxy when bidding on keywords in newly set-up SEA campaigns. This research extends the stream of literature on how to determine optimal bids, which so far focuses on campaigns that are already running and where the required data to calculate bids is already available. This research offers a novel approach of determining bids when advertisers lack the aforementioned information.

A topic of this master thesis is designing and implementing a Content Management System that would contain SEO optimization options in the basis. The objective of this thesis is to improve quality of produced websites and to increase awareness about SEO optimization. According to the defined problem the thesis first analyzes existing CMS systems. Afterwards the solution is suggested which consists of a combination of the existing CMS system OctoberCMS and a plugin that extends the system with the necessary functionality. The last part of the thesis is devoted to designing the implementation and testing the final solution.

As the Web evolves unexpectedly fast, information grows explosively. Useful resources become more and more difficult to find because of their dynamic and unstructured characteristics. A vertical search engine is designed and implemented towards a specific domain. Instead of processing the giant volume of miscellaneous information distributed in the Web, a vertical search engine targets at identifying relevant information in specific domains or topics and eventually provides users with up-to-date information, highly focused insights and actionable knowledge representation. As the mobile device gets more popular, the nature of the search is changing. So, acquiring information on a mobile device poses unique requirements on traditional search engines, which will potentially change every feature they used to have. To summarize, users are strongly expecting search engines that can satisfy their individual information needs, adapt their current situation, and present highly personalized search results. In my research, the next generation vertical search engine means to utilize and enrich existing domain information to close the loop of vertical search engine's system that mutually facilitate knowledge discovering, actionable information extraction, and user interests modeling and recommendation. I investigate three problems in which domain taxonomy plays an important role, including taxonomy generation using a vertical search engine, actionable information extraction based on domain taxonomy, and the use of ensemble taxonomy to catch user's interests. As the fundamental theory, ultra-metric, dendrogram, and hierarchical clustering are intensively discussed. Methods on taxonomy generation using my research on hierarchical clustering are developed. The related vertical search engine techniques are practically used in Disaster Management Domain. Especially, three disaster information management systems are developed and represented as real use cases of my research work.

Search engine algorithms are constantly improved in order to provide the highest quality and most relevant results for the user. Google algorithm updates called Panda and Penguin have recently been one of the most significant and many websites that use black hat SEO techniques were hit by them. Nowadays, using this search optimization's techniques raises the risk of Google penalty, which in most of the cases cause decrease in traffic from organic search. The aim of this thesis is to describe techniques of search engine optimization (SEO) and their possible impact on website's ranking. The thesis also aims to verify whether Penguin and Panda updates have the impact on websites for which the methods of black hat SEO have been used and specify the result of this impact. In the theoretical part of this thesis it is described function of search engines Seznam.cz and Google, their algorithm change in history and possible factors on which the ranking score is based. Briefly are also described tools, which can be used to identify and analyze possible causes of penalization. After reading this thesis, the reader will have a basic orientation in search engine optimization methods and their appropriate use. Also, he will be able to recognize possible causes of Google penalty and propose an appropriate strategy for its removal.

This thesis gives an insight into the field of internet marketing with a special focus on Search Engine Optimization (SEO). For the purpose of this thesis one website is selected and analysed in order to determine how successfully SEO has been performed. Different sources of visitors are analyzed and their activity is measured. The goal of this thesis is to give a set of recommendations to the operators of this website. Based on those recommendations the operators should be able to increase the number of visitors. In addition, this work also contains a comprehensive overview of basic internet marketing methods with a more detailed overview of different factors which influence SEO. This focus is both on OnPage and OffPage factors.

Internet enhances the rapid globalization of markets and user often has no means to figure out which national legislation is relevant for him when he is visiting the site. This issue gains importance in the commercialization of relationships, where the traditional, local regulations of this dynamic business environment are often inadequate. This paper aims to look through the analysis of various legal aspects, reveal gaps in existing legislation and determine with the help of international comparisons of, still very different, legal arrangements and practice (particularly judicial decisions) of selected countries, which questions are handled appropriately for the purpose of effective regulation of electronic commerce and whether there might be inspiration from foreign regulation and practice for the Czech law system in the future.

This thesis aims to analyse the behaviour of an “analogue search engine”, created by the romance novel community. The existing commercial recommendation systems for romance novels are found lacking, as they fail to fill the requirements of the user group. The user group fills this need by creating separate communities, where they use their expertise in the genre to create a more accurate recommendation system.  Using ethnographic research over a long period of time allowed the behaviours and habits of the group to be catalogued. Using that framework and interaction design practises, several design proposals were created showing how the findings can be used to add nuance to recommendation system interfaces.
