Google Search


Google Search (or Google Web Search) is a web search engine owned by Google Inc. Google Search is the most-used search engine on theWorld Wide Web, receiving several hundred million queries each day through its various services.

The order of search results on Google's search-results pages is based, in part, on a priority rank called a "PageRank". Google Search provides many options for customized search, using Boolean operators such as: exclusion ("-xx"), alternatives ("xx OR yy"), and wildcards ("x * x").

The main purpose of Google Search is to hunt for text in publicly accessible documents offered by web servers (in formats such as HTML, PDF, etc.), as opposed to other data, such as with Google Image Search. Google Search was originally developed by Larry Page and Sergey Brin in 1997.Google Search provides at least 22 special features beyond the original word-search capability. These include synonyms, weather forecasts, time zones, stock quotes, maps, earthquake data, movie showtimes, airports, home listings, and sports scores. There are special features for dates, including ranges (70..73), prices, temperatures, money/unit conversions ("10.5 cm in inches"), calculations ("3*4+sqrt(6)-pi/2"), package tracking, patents, area codes, and language translation of displayed pages. In June 2011, Google introduced "Google Voice Search" and "Search by Image" features for allowing the users to search words by speaking and by giving images. In May 2012, Google introduced a new Knowledge Graph semantic search feature to customers in the U.S.

The frequency of use of many search terms has reached such a volume that they may indicate broader economic, social and health trends. Data about the frequency of use of search terms on Google (available through Google Adwords, Google Trends, and Google Insights for Search) have been shown to correlate with flu outbreaks and unemployment levels and provide the information faster than traditional reporting methods and government surveys.

Major competitors of Google are Baidu and Soso.com in China and South Korea; Naver.com and Daum Communications, in South Korea; Yandexin Russia; Seznam.cz in Czech Republic; Yahoo! in Japan Taiwan and USA. Another potential competitor is Bing.

Search Engine Optimization

Search Engine Optimization

Search engine optimization (SEO) is the process of affecting the visibility of a website or a web page in a search engine's "natural" or un-paid ("organic") search results. In general, the earlier (or higher ranked on the search results page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine's users. SEO may target different kinds of search, including image search,local search, video search, academic search, news search and industry-specific vertical search engines.

As an Internet marketing strategy, SEO considers how search engines work, what people search for, the actual search terms or keywords typed into search engines and which search engines are preferred by their targeted audience. Optimizing a website may involve editing its content, HTML and associated coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines. Promoting a site to increase the number of backlinks, or inbound links, is another SEO tactic.

The plural of the abbreviation SEO can also refer to "search engine optimizers," those who provide SEO services.
