3. Google's Search Engine Launched by Larry Page and Sergey Brin in 1997. Searches for text only. Available in 132 languages. Google owns over 160 domain names for various countries, besides google.com.[1] Monthly Internet Crawl and Indexing. Use Page Rank algorithm.

4. Google's Page Rank Matches the queried string. Previous methods used keyword-matching. Page Rank analyses human generated links. Co-relates to the human aspect of thinking. Has been modified to include 200+ indicators and criteria.

5. Google's Current and Future Snapshots non text content. PDF, Word, Excel, Flash etc. Deepweb is still pretty much unaccesible to the search engine. Negative reviews of a business would increase the search rank, this problem has been fixed. I'm feeling lucky costs Google $110 million/annum. [2] Special features: weather, US zipcode, calculations, time, numeric ranges, map, movie showtime, public data, real estate and housing, travel data/airports, package tracking, patent numbers, area code, synonym search and others.

9. Let's talk technology...

10. Search Technology Google's Googlebot is more effective at crawling the web than competing engines More sophisticated at filtering out web pages for targeted phrases related to search query Good at differentiating between real text patterns and spammy text Better than other search engines at determining the true intent of a query and trying to match that versus doing direct text matching. Since 1996

11. Search Technology Bing's MSNbot (soon to be called “Bingbot”) has gotten better over time at crawling but still not as good as Google at crawling deeply through large sites (such as eBay). Does try to process queries for meaning instead of direct text matching – not on par with Google yet. Since Microsoft started doing search later in the game, it has a harder time determining natural links from spammy/bought links. Still takes longer than Google to get new websites in their index. Since 2005

12. Bing steals Google search results ... --- and denies it !

13. It all started with “tarsorrhaphy”. REALLY! Tarsorrhaphy is a rare surgical procedure on eyelids. Summer of 2010, Google engineers were looking at search results for misspelled query [torsorophy] Google returned correct spelling along with the search results. At this time Bing had no search results for the same keyword.

14. Later in the summer , Bing started returning Google’s first result without the offering the spell correction. Strange ? How could they return our first result to their users without the correct spelling? Had they known the correct spelling.

15. Google asked their engineers to enter some synthetic queries into the search box on the Google home page. Within a couple weeks results started appearing in Bing. Bing Denies this allegation.

16. Re-cap Google still on top – used by more Internet savvy and business to business searchers. Bing skews slightly older, more “shoppers”. Bing will be #2 in the search engine industry. Others in the industry are way behind the curve. Recap
