Google in the past and present

Posted by David Khoirul
Matt Cutts, the Google engineer specializing in Search Engine Optimiziation (SEO), wrote an interesting post in his personal blog, comparing search engine Google in the past to the present. There have been a lot of changes for sure. In 2001, when only few people understood how Google algorithms worked, spamming was a rare case.

...there was no spam on Google back then. Google in 2000 looked great in comparison with other engines at the time, but Google 2011 is much better than Google 2000. I know because back in October 2000 I sent 40,000+ queries to google.com and saved the results as a sort of search time capsule. Take a query like [ buy domain name]. Google’s current search results aren't perfect, but the page returns several good resources as well as some places to actually buy a domain name.

He also mentioned what he called "host crowding," which was introduced in 2000:

In 1999 and early 2000, search engines would often return 50 results from the same domain in the search results. One nice change that Google introduced in February 2000 was “ host crowding,” which only showed two results from each hostname ( here’s what a hostname is ). Suddenly, Google’s search results were much cleaner and more diverse!
