| #4 in Search Engine | Google search is the most used search engine on the web. Google receives several hundred million queries each day through its various services. Besides the main search engine feature of searching for text, the search engine can also be used as a calculator, base, unit and currency converter, dictionary and many other useful tools. Google search was originally developed by Larry Page and Sergey Brin in 1997. Google's algorithm uses a patented system called PageRank to help rank web pages that match a given search string. The PageRank algorithm computes a recursive score for web pages, based on the weighted sum of the PageRanks of the pages linking to them. The PageRank derives from human-generated links, and is thought to correlate well with human concepts of importance. The exact percentage of the total of web pages that Google indexes is not known, as it is very hard to actually calculate. | 1 | 0 | 1 | 0 0 0 0 0 | Free | http://www.google.com | Web | ||
| #1 in Scour #7 in Search Engine | Scour is a search tool that blends results from Google, Yahoo, and MSN together in one stream. You can hot-swap between the three, or break out any single result into another search. If you come across a bad result, or one you think should go above the others, you can also vote it up (or down) or leave a comment. Unlike traditional search engines, Scour also has something called Friends Feed, which keeps track of friends on the service and tells you what results they are commenting on. It also rewards users with gift cards for searching, voting, and commenting on good results; doling out points for each user action. | 1 | 0 | 1 | 0 0 0 0 0 | Free | http://scour.com | Web |
