How does google determine the order of websites in a search result?

[Fiona]

Google ranks using three main criteria. First, it looks to keyword match, therefore if someone enters "banana" into Google, it looks for a webpage that says "banana". Second, it looks to return a local result. Thus if you entered "banana" in Australia, it will look to display and Australian banana result first. Finally, if multiple webpages match the phrase and origin of the person searching for it, Google will apply its algorithm called PageRank to decide who gets to rank in the different positions.
