Search engines use different criteria for ranking pages, and those criteria are periodically changed to keep Web page designers from falsely describing their pages and obtaining a permanent, high ranking. This is why an entire industry exists to help Web site owners obtain high results page ranking
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 to submit the address of a page, or URL, to the various engines which would send a "spider" to "crawl" that page, extract links to other pages from it, and return information found on the page to be indexed.[2] The process involves a search engine spider downloading a page and storing it on the search engine's own server, where a second program, known as an 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 contains, which are then placed into a scheduler for crawling at a later date.
webmasters were even manipulating their rankings in search results by stuffing pages with excessive or irrelevant keywords. Early search engines, such as Altavista and Infoseek, adjusted their algorithms in an effort to prevent webmasters from manipulating rankings.[22]
The leading search engines, such as Google, Bing and Yahoo!, use crawlers to find pages for their algorithmic search results. Pages that are linked from other search engine indexed pages do not need to be submitted because they are found automatically. Some search engines, notably Yahoo!, operate a paid submission service that guarantee crawling for either a set fee or cost per click.[30] Such programs usually guarantee inclusion in the database, but do not guarantee specific ranking within the search results.[dead link][31] Two major directories, the Yahoo Directory and the Open Directory Project both require manual submission and human editorial review.[32] Google offers Google Webmaster Tools, for which an XML Sitemap feed can be created and submitted for free to ensure that all pages are found, especially pages that aren't discoverable by automatically following links.[33]
Image search optimization is the process of organizing the content of a webpage to increase relevance to a specific keyword on image search engines. Like search engine optimization, the aim is to achieve a higher organic search listing and thus increasing the volume of traffic from search engines.
