A thread was created at WebmasterWorld forums named Has ASK Jeeves Updated its Index? but moderator martinibuster. Martinibuster says that he has noticed that Ask.com has been sending him traffic for a page that is about ten days old. That implies that Ask.com's index, which is normally slower to index new pages than Google, Yahoo or MSN, has become fresh with new pages. Martinibuster also believes that Ask.com has "tweaked their algo" to provide higher quality results. For the few searches martinibuster placed, he said the quality is on par with Google and seems to be better than Yahoo results.
Have you been noticing the same thing?
