what is seo
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.[jargon] 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 prefer your target audience. Optimizing a website may involve editing its content, HTML and associated coding to both increase the relevance of 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. what are backlinks SEO may also refer to the plural abbreviation for "search engine optimizers," those who offer SEO services.
Webmasters and content providers began optimizing sites for search engines in the mid 1990s, as the first search engines were cataloging the early Web. Initially, all webmasters needed to do was submit site address or URL of the various engines which would send "spider" to "crawl" that page, extract links to other web sites, and return information found in a crawl. The process involves a search engine spider downloading a page and storing the search engine's own server, where a second program called the indexer, extracts various information about the page, such as the words it contains and where these are located, as well as any weight for specific words, and all links the page, which is then placed in a scheduled crawl later. blogger Site owners started to recognize the value of whose sites highly ranked and visible in search engine results, creating a possibility for both white hat and black hat SEO practitioners. According to industry analyst Danny Sullivan, the phrase "search engine optimization" probably came into use in 1997. [3] The first recorded use of the term Search engine optimization was John Audette and his company Multimedia Marketing Group as documented by the MMG web site, August 1997. buy edu backlinks Early versions of search algorithms relied on webmaster to set information such as the keyword meta tag, or index files in engines like Aliweb. Meta tags provide guidance on the content of each page. Using metadata index pages was found to be less than reliable, however, because the webmaster to select the keywords meta tag could be inaccurate presentation of the actual content of the site. Inaccurate, incomplete, and inconsistent data meta tags could and did cause pages to rank irrelevant searches. [5] [dubious - discuss] Web content providers also manipulated the number of attributes of the source HTML page trying to rank well in the search engines.
By relying so much on factors such as keyword density is exclusively within a webmaster's control, early search engines abuse and ranking manipulation. To provide better results to their users, search engines had to adapt to ensure their results pages showed the most relevant search results, rather than unrelated pages stuffed with keywords by unscrupulous webmasters. Since the success and popularity of a search engine is determined by the ability to produce the most relevant results to any given search, allowing those results to be false would turn the users to find other search sources. Search engines responded by developing more complex ranking algorithms, taking into account the additional factors is more difficult for webmasters to manipulate. Graduates at Stanford University, Larry Page and Sergey Brin, developed "BackRub" a tool search based on a mathematical algorithm to evaluate the prominence of web pages. The number calculated by the PageRank algorithm, which is a function of the quantity and strength of inbound links. PageRank estimates the likelihood that a given page will be reached by a web user who randomly surfing the web, and follow links from one page to another. In practice, this means that some links are stronger than others, as a higher PageRank page is more likely to be achieved by the random surfer. best buy wiki Page and Brin founded Google in 1998. Google attracted a loyal among the growing number of Internet users, who liked its simple design. Off-page factors (like PageRank and hyperlink analysis) as well as on page factors (like keyword frequency, meta tags, headings, links and site structure) to be considered to enable Google to avoid the kind of manipulation seen in search engines that only considered on page factors for their rankings. Although PageRank was more difficult to game, webmasters had developed link building tools and programs to influence the Inktomi search engine, and these methods proved similarly to the PageRank game. Many sites focused on exchanging, buying and selling links, often on a large scale. Some programs, or link farms, involved the creation of thousands of sites for the sole purpose of link spamming. google pagerank By 2004, search engines have incorporated a wide range of undisclosed factors in their ranking algorithms to reduce the impact of link manipulation. In June 2007, The New York Times Saul Hansell said Google ranks sites using more than 200 different signals. The leading search engines, Google, Bing, and Yahoo, do not disclose the algorithms they use to rank pages. Some SEO practitioners have studied different approaches to search engine optimization, and shared their personal opinions related to patent search tools can provide information to better understand the search engines. social bookmarks In 2005, Google began to personalize the search results for each user. Depending on their history of previous searches, Google crafted results for user login. In 2008, Bruce Clay said that "ranking is dead" because of personalized search. He stated that it would become meaningless to discuss how a website ranked, because its rank would likely be different for each user and each search. social bookmark
In 2007, Google announced a campaign against paid links that transfer PageRank. June 15, 2009, Google disclosed that they had taken measures to mitigate the effects of PageRank sculpture by use of the nofollow attribute on links. Matt Cutts, a well-known software engineer at Google, announced that Google Bot not treat nofollowed links in the same way, to prevent SEO service providers from using nofollow for PageRank sculpture. As a result of this change the usage of nofollow leads to evaporation of PageRank. To avoid the above, SEO engineers developed alternative techniques that replace nofollowed tags with obfuscated Javascript and thus permit PageRank sculpture. Additionally several solutions suggested include the use of iframes, Flash and Javascript. link building strategy In December 2009, Google announced it would be using the web search history of all its users to populate search results.
Google Instant, real-time-search was introduced in late 2010 in an attempt to make search results more timely and important. Historically site administrators have spent months or even years optimizing website to increase search rankings. With the increase in popularity of social media sites and blogs the leading engines made changes to their algorithms to allow fresh content to rank quickly within the search results.
In February 2011, Google announced the "Panda update, which penalizes sites containing content duplicated from other sites and sources. Historically websites copied content from each other and benefit search engine ranking of engaging in this practice, however, Google has implemented a new system that penalizes sites whose content is not unique.
In April 2012, Google launched the Google Penguin change the purpose of that was to punish websites that use manipulative techniques to improve their ranking in search engine
