121,617,892,992 web pages - that’s the number of pages that Cuil, a new search engine claims to index. It’s a lot. More than 120 billion pages, wow!

Cuil searches more pages on the Web than anyone else—three times as many as Google and ten times as many as Microsoft.

Google don’t disclose the information regarding their index size, but according to this statement they store about 40 billion web pages. Cuil seems to be the search engine that holds the most comprehensive index of web pages on the Internet, even thought Google identified 1 trillion unique URL’s on the Internet.

Cuil overview

Cuil was founded by Tom Costello (CEO), Anna Patterson (VP of Engineering) and Russell Power (Co-founder). They managed to raise $33M in funds for the project from Madrone Capital Partners, Greylock Partners and Tugboat Ventures.

Since the developing stage the company dropped out from one “l” in the name, changing from “Cuill” to “Cuil”, pronounced as “cool”.

Cuil- the powerful search engine

2 ex-Google employees, Patterson and Power, made a breakthrough and claim to find a way to collect and store web data faster and much more cost-effective than Google, which is speculated to spend over 1 billion dollars to maintain their search engine infrastructure per year. That’s one of the main reasons their database is so huge (storing one page is cheaper than at Google meaning they can store more pages at the same cost as Google) and the way to convince their sponsors to give their money to the Cuil company.

Cuil claims to have better search engine results relevancy than Google and other search engines. It rank websites in a different way than Google and other search engines. Their approach is more semantic. Cuil tries to categorize web pages based on their meaning, even if the category name does not appear on the web page itself.

Cuil search engine is experimenting with different type of search interface where results are shown in three columns, with picture, more text describing a website and “Explore by website” feature. That last feature suggests other related categories to the search query.

At this point Cuil is not showing any sponsored results or other forms of online ads.

Cuil principles

The Internet is getting bigger and more disorganized every day. Cuil’s goal is to solve the two great problems of search: how to index the whole Internet—not just part of it—and how to analyze and sort out its pages so you get relevant results… Size matters because many people use the Internet to find information that is of interest to them, even if it’s not popular.

Privacy Policy is very important to the startup search engine. They do not store any data, not IP, no personal identifiable informations, nothing. As they use semantic search algorithm they don’t need to know their users habits, click-through and general Internet behavior.

Because Cuil analyzes Web pages and not click-throughs, we don’t need to know your search history and habits. So our privacy policy is very simple: when you search with Cuil, we do not collect any personally identifiable information, period…Your search history is your business, not ours.
