Search engine optimization (SEO)
Search engine optimization (SEO) is a set of methods aimed at improving the ranking of a website in search engine listings, and could be considered a subset of search engine marketing. The term SEO also refers to search engine optimizers, an industry of consultants who carry out optimization projects on behalf of clients websites. Some commentators, and even some SEOs, break down methods used by practitioners into categories such as white hat SEO (methods generally approved by search engines, such as building content and improving website quality), or black hat SEO (tricks such as cloaking and spamdexing). Search engines display different kinds of listings in the search engine results pages (SERPs), including: pay per click advertisements, paid inclusion listings, and organic search results.
Link popularity
Link Popularity is one of the best ways to measure your website's online visibility and overall Web presence. It is ascertained by the number of websites that link to your website and is an important factor in guaging your website's importance, increasing your website traffic and determining your website's ranking in major search engines like Google. There are many ways to increase link popularity but most effective way is exchange links with all of our websites.
Page Rank
Page Rank is a patented method to assign a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of measuring its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is also called the PageRank of E and denoted by PR(E). PageRank was developed at Stanford University by Larry Page (hence the name Page-Rank [Vise and Malseed, 2005]) and Sergey Brin as part of a research project about a new kind of search engine. The project started in 1995 and led to a functional prototype, named Google, in 1998. Shortly after, Page and Brin founded Google Inc., the company behind the Google search engine. While just one of many factors which determine the ranking of Google search results, PageRank continues to provide the basis for all of Google's web search tools. PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at more than the sheer volume of votes, or links a page receives; it also analyzes the page that casts the vote.
Search engines
Search engine or search service is a program designed to help find information stored on a computer system, such as on the World Wide Web, inside a corporate or proprietary network, or in a personal computer. The search engine allows one to ask for content meeting specific criteria (typically those containing a given word or phrase) and retrieves a list of references that match those criteria. Search engines use regularly updated indexes to operate quickly and efficiently. Without further qualification, search engine usually refers to a Web search engine, which searches for information on the public Web. Other kinds of search engine are enterprise search engines, personal search engines and mobile search engines.
Web directory
A web directory is a directory on the World Wide Web. It specializes in linking to other websites and categorizing those links. A web directory is not a search engine, and does not display lists of web pages based on keywords, instead it lists websites by category and subcategory. The categorization is usually based on the whole website, rather than one page or a set of keywords, and websites are often limited to inclusion in only one or two categories. Web directories often allow website owners to directly submit their website for inclusion, and have editors review submissions for fitness.
Alexa rank
Alexa ranks websites based on visits from users of its Alexa Toolbar for Internet Explorer and from integrated sidebars in Mozilla and Netscape. There are several third-party extensions for Mozilla Firefox; these extensions do affect Alexa rankings. There is some controversy over how representative Alexa's user base is of typical Internet behavior. If Alexa's user base is a fair statistical sample of the internet user population (e.g., a random sample of sufficient size), Alexa's ranking should be quite accurate (see Sampling). In reality, not much is known about the sample and it may or may not have many sources of sampling bias. Another concern is whether Alexa ratings are easily manipulated. Some webmasters claim that they can significantly improve the Alexa ranking of less popular websites by making them the default page, by exchanging web traffic with other webmasters, and by requiring their users to install the Alexa toolbar; however, such claims are often anecdotal and are offered without statistics or other evidence.
