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.
A traffic exchange website receives website submissions from webmasters that join traffic exchange networks. The person who submitted the website then has to browse other member sites on the exchange program to earn credits, which enable their sites to be viewed by other members through the surf system. This increases the number of visitors to all the sites involved. Exchanges enforce a certain credit ratio, which illustrates the amount of websites the surfer must view in order to receive one hit through the program for their promoted website. Many sites offer the ability to upgrade one’s membership level for a more equal credit ratio.
As the viewers are all website owners or affiliates, it is possible that some might find certain member sites interesting and thus make note of them on their own sites, sending more traffic their way. Most traffic programs also impose a time limit when members are browsing, ranging from 10 seconds to 60 seconds. Some incorporate the use of captcha to ensure user interaction. 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 refer to “search engine optimizers,” those who provide SEO service.
Backlinks, also known as incoming links, inbound links, inlinks, and inward links, are incoming links to a website or web page. In basic link terminology, a backlink is any link received by a web node (web page, directory, website, or top level domain) from another web node. Inbound links were originally important (prior to the emergence of search engines) as a primary means of web navigation; today, their significance lies in search engine optimization (SEO). The number of backlinks is one indication of the popularity or importance of that website or page (for example, this is used by Google to determine the PageRank of a webpage). Outside of SEO, the backlinks of a webpage may be of significant personal, cultural or semantic interest: they indicate who is paying attention to that page.
