Google Web Index Hits 1 Trillion URLs
The main popularity of Google is its ability in having extensive database of links, which at the last count, has exceeded one trillion. Two Google engineers on Friday said that Google’s index of the Web now contains 1 trillion unique URLs.
When the company started business In 1998, Google index had 26 million pages and it had surpassed 1 billion mark by the end of the year 2000. The content grows rapidly in the last 8 years. So it appears that Google’s index is expanding with new Web pages. From 2000 to 2005, Google’s index grew by a factor of 8. From 2005 to 2008, it grew by a factor of 125.
“Back then, we did everything in batches: one workstation could compute the PageRank graph on 26 million pages in a couple of hours, and that set of pages would be used as Google’s index for a fixed period of time. Today, Google downloads the web continuously, collecting updated page information and re-processing the entire web-link graph several times per day,” says Google’s blog.
The link graph is the mathematical calculation about what links to what. Google PageRank Algorithm analyzes all of the links and rank them based upon the importance of the content.
