Why is google the most successful search engine
In Earlier sites , search results were not displayed based on relevance, who ever paid more were getting their listings. They use to match search terms to websites by analysing the texts of a webpage. Many websites often took undue advantage of this and inserted irrelevant words to get benefit of search bots.
However, Google later introduced Pagerank algorithm where pages were listed based on number of sites linked to a particular webpage. Weightage was given to those results with linkages to a prominent website than smaller websites.
Later Google Introduced Adwords where advertisers would pay for their websites which would appear before the search results of relevant keywords.
The Company made huge profits in advertising , which it invested in R&D for more refined search engine , more targeted advertisements with more value services.
Google is fast, simple and accurate. Some people paly with the algorithams, but google is getting smarter day by day.
Google does not have any compititor as of now, Yahoo and Bing are still in the stage where google was before 5 years.
Results on google are much better than Bing or Yahoo.
Another reason google is on top is sharing of revenue with website owners. Income of google comes from advertising, google have adsense program where webmasters can advertise the ads of google and share the income.
