A Quick History of Search Engine Optimization

Search engine optimization is that the art and science of creating web pages attractive to web search engines. Some interne t businesses think about search engine optimization to be the subset of search engine marketing.

In the center of the Nineties webmasters and search engine content suppliers started optimizing websites. At the time all the webmasters had to strive and do was offer a URL to a probe engine and a net crawler would be sent from the search engine. The internet crawler would extract link from the webpage and use the knowledge to index the page by down loading the page and then storing it on the search engines server. Once the page was stored on the search engines server a second program, called an indexer, extracted extra information from the webpage, and determines the weight of specific words. When this was complete the page was ranked.

It did not take very long for people to understand the importance of being highly ranked.

In the beginning search engines used search algorithms that webmasters provided about the web pages. It didn't take webmasters very long to start abusing the system requiring search engines to develop a additional sophisticated form of search engine optimization. The search engines developed a system that thought of several factors; domain name, text within the title, URL directories, term frequency, HTML tags, on page key word proximity, Alt attributes for pictures, on page keyword adjacency, text inside NOFRAMES tags, internet content development, sitemaps, and on page keyword sequence.

Google developed a replacement concept of evaluating internet web pages known as PageRank. PageRank weighs a web page's quantity and quality primarily based on the pages incoming links. This technique of search engine optimization was so successful that Google quickly began to get pleasure from successful word of mouth and consistent praise.

To help discourage abuse by webmasters, several internet search engines, like Google, Microsoft, Yahoo, and Ask.com, can not disclose the algorithms they use when ranking net pages.The signals used these days in search engine optimization typically are; keywords within the title, link popularity, keywords in links pointing to the page, PageRank (Google), Keywords that seem in the visible text, links from on page to the inner pages, and placing punch line at the top of the page.

For the most part registering a webpage/web site on an enquiry engine may be a simple task. All Google requires is a link from a web site already indexed and also the internet crawlers will visit the location and start to spider its contents. Normally a few days once registering on the search engine the main search engine spiders can begin to index the website.

Some search engines will guarantee spidering and indexing for a little fee. These search engines do not guarantee specific ranking. Webmaster's who don't need net crawlers to index sure files and directories use a customary robots.txt file. This file is located in the basis directory. Often a net crawler will still crawl a page whether or not the webmaster has indicated he will not want the page indexed.
