At present, there are approx. 614 million registered Hostnames2 and approx. 184 million active websites, corresponding to the available statistics of the web analysis service Netcraft.3 The latter value does not refer to single websites belonging to everything for this IP-address, but identified Internet addresses only on these by a single IP-address. This answers a http inquiry and distribute a website. The number of all websites cannot easily estimate, because of many factors like the strong size differences and dynamic websites. If one searching at Google for the concept http or WWW one gets a value of over 25 billion of websites delivered, which seems to be almost realistic. 4 After statistics of internetworldstats.com5 almost 2.2 billion people (approx. 32 percent of the world population) using the Internet today, thereby is the number in the past 11 years increased by 528 percent. In Europe, approx. 500 million people are using the Internet, of these around 67 million in Germany. According to this in Germany, there are meanwhile more than 82 percent of the citizens, which are using the Internet. For the named data there are broader aspects, which have influence to the information retrieval. Different languages, expired information, differently format for example documents, music, video or pictures, fall under this. In addition, it can be obstructive due to the steady updates of the contents to regain the same information at a later occasion. Out of the introduction, it gets obvious, that the abstract of searching and finding by search engines brings already many questions with themselves. Because of the expected extent, this work cannot answer the topic and possible questions profoundly and extensively and rather serves fundamental researches for further work.

Excerpt from the Book
2.1 Types of search engines
Shortly after the development of the (WWW) by Tim Berners Lee in 1989, have already been developed the first search engines. The amount of different hypertexts in 1990, were no longer manageable for humans. The first manual cataloguing was replaced by search technologies such as web crawlers (see chapter 2.3), which were already able to valuate and sort their results. This so called ranking method (see chapter 2.3) was enhanced by the proximity of various search terms with each other, on whose algorithm generally was also based on the 1998 established search engine Google.
The breakthrough came with the introduction of Google’s "PageRank" (see chapter 2.3), through that the relevance of an information recursively by the links to themselves the self importance increased. That means ever known a website through the links referring to it is, the more important it seems, and thus gets a higher ranking. Due to these supposedly more quality content, Google could reach a global market share of 83 percent, so that the next smaller such as Yahoo 6.4 percent and Bing 3.9 percent having a negligible role. The success of search engines is not only cause by the high level of recognition, but on their advertising to businesses in all sectors of the economy. Thus, Google was able to generate in 2011 a revenue of nearly 38 billion USD and Yahoo 5 billion USD. In addition to general search engines like Google & Co. there are also specialized search engines with focus on the separate search content such as news, video clips or music.

Frequently Asked Questions
What is the core focus of this seminar paper?
The paper examines how search engines function, their role in information retrieval, and their significant economic influence through marketing models like keyword advertising.
What are the primary thematic areas covered?
Key themes include the technical architecture of search engines, the evolution of search types, user interaction behavior, and the expansive business model of major providers like Google.
What is the primary research goal of the work?
The work aims to provide a fundamental research framework to understand the complex requirements and mechanisms search engine providers face when managing vast amounts of web data.
Which scientific methods are utilized?
The paper primarily utilizes a literature-based analysis and observational studies regarding user behavior, such as eye-tracking, to validate how search results are perceived.
What content is discussed in the main body?
The main body covers the technical components (crawlers, parsers, indexers), the classification of search types, the "Golden Triangle" of user attention, and the diversification of Google's services.
Which keywords best characterize this work?
The core keywords include Search Engines, Information Retrieval, SEO, SEM, PageRank, and the Google Matrix.
How does the "Golden Triangle" influence search engine marketing?
It describes a specific user scanning pattern where attention is focused on the top-left results, emphasizing the necessity for high-ranking advertisements to be placed in these visibility zones.
Why are specialized search engines considered necessary?
They are required for accessing areas of the web that general crawlers cannot reach, such as password-protected databases or specific content like scientific archives or niche blogs.
What is the significance of the "Google Matrix" in this paper?
It illustrates the strategy of diversification, showing how Google extends its influence beyond simple search queries into areas like mapping, mobile operating systems, venture capital, and retail.
What future developments are projected for search engines?
The author predicts a shift towards deeper integration with personal data, potentially involving advanced speech recognition and more context-aware, personalized search results.
