Go on, give it a test, search for something really obscure. Try out Cuil - billed as the next generation search engine, the Google beater, the next big thing, the search engine that indexes 121 billion pages.

All the hype around this comes from the three people behind this project. 3 Tech genius with two who is responsible for Google’s search teams. With that pedigree, you must think Cuil is very good.
Now that’s only half the story. In business, your product is only as good as the marketing behind it. And behind Cuil is Manning Selvage & Lee, one of the most respected PR firms in the world (they are part of Publicis). So the marketing buzz you hear about Cuil isn’t there by accident.
So what about the result? Does things rank well? Other then the “Cuil(cool)” design. It’s hard to say without a blind test, but what from my obscure searches done on verticals I’m very familiar with, I have to say of the top 10 results, there is at least one that is very relevent, which is actually saying it’s just as good as any other search engine.
Search is made up of three areas. Spidering, Indexing and Ranking. The first two is easy, big server, smart spiders, lots of investement and you are there. It’s ranking results accuratly thats the hard part. Cuil may index 3 times more pages then Google, but unless those results get ranked accuratly, it’s only use is good PR.
I think the jury is still out on who’s better, but I will give Cuil a chance. Let’s see how well it uses on site relevency to rank the results and see how it compares with user generated results in the future.
