The algorithms aren't the critical part of Google's engine- it's the signals which help the system learn what you're interested in. This is why Bing is desperate to get traffic- as long as it's numbers are low then it has significantly fewer signals which cause its ads to underperform. This is also the source of the 'Bing is copying our results' kerfuffle last year- http://searchengineland.com/google-bing-is-cheating-copying-our-search-results-62914 http://searchengineland.com/google-bing-is-cheating-copying-.... Bing needed more signals, so used the toolbar to get them, inadvertently copying Google.
