Google now processes about 1.2 trillion searches per year worldwide. Its about 100 billion searches per month or 3.5 billion searches per day or over 40,000 search queries every second.
- In 1999, it took Google one month to crawl and build an index of about 50 million pages.
In 2012, the same task was accomplished in less than one minute.
- 16% to 20% of queries that get asked every day have never been asked before.
- Every query has to travel on average 1,500 miles to a data center and back to return the answer to the user.
- A single Google query uses 1,000 computers in 0.2 seconds to retrieve an answer.
