SEO began in the mid-1990s, as the first search-engines were cataloging the early Web. Initially, all a webmaster needed to do was submit a site to the various engines which would run spiders, programs to “crawl” the site, and store the collected data. The default search-bracket was to scan an entire webpage for so-called connected search-words, so a page with many not the same words matched more searches, and a webpage contains a dictionary-type listing would match closely all searches, limited only by unique names. The search-engines then sorted the information by topic, and served results based on pages they had spidered. As the number of documents online kept growing, and more webmasters realized the value of organic search listings, so stock search engines began to sort their listings so they could display the most relevant pages first. This was the start of a friction between search engine and webmaster that continues to this day.
