Search Engines History

Early search engines
The first search engines were cataloging in early 1990s when Web Webmasters and content providers began optimizing sites for search engines. In the beginning, webmaster needed to submit a web site to the search engines which run spiders, programs to "crawl" the site, and store the collected data. Search words or keywords were the buzz that time. The search bracket used to scan the entire webpage for the words and this used to match maximum searches. If you have a site with words gorged then you will be placed in top. The default search-bracket was to scan an entire webpage for so-called related search words, so a page with many different words matched more searches, and a webpage containing a dictionary-type listing would match almost all searches. The search engines categorize information by topic after the search crawlers submit them the details. Gradually the whole scenario was changed with the arrival of more websites everyday. After this, some search engines started categorizing websites for better organic search engine results.
Initially, webmasters used to guide search engines and this had influenced the search results. Search engines were dependent upon the webmaster provided information which included the category, keywords, index files and Meta tags. Meta-tags are the words or phrases that provided a guide to the content of the website. Very soon webmasters learned the art of misusing these Meta tags for irrelevant search results. Hence, search engines start avoiding Meta tags and developed more complex algorithm for search engine ranking. The new algorithm included the text within the title tag, domain name, URL directories and the file names. HTML tags like heading, emphasized, strongly emphasized text were inserted. Image attributes were essential. Gradually it became a total keyword game where you need to be careful about the keyword density, adjacency, keyword sequence and the Content development.
