He first noticed Yahoo Search changes yesterday afternoon, saying "Seeing movement." He was then backed up by full member, Vimes, who said, "I'm seeing something not sure if I'd call it an update just yet, the sectors i look at there is a shuffle." So this may be the beginning of a Yahoo update or it might be some sector tweaks. We are due a Yahoo update, the last one we noticed was back in November 2008, since then, there have been no confirmed Yahoo Search updates. So having an update now, would not surprise me.
On the Ask.com front, there is a bit more discussion going on, being that the update was reported at WebmasterWorld a bit earlier. Textex called this update "a complete overhaul." Full member, robzilla, confirmed but cautioned that this update doesn't seem to be "an improvement" to their index. Soon later, they both noticed that clearing their cookies reset the "results reverted back" to their previous state. This implies that the results might be a test on some users. I did some of my own testing and the results do seem a bit better. Still not what I consider "fresh" results, but a bit better on the few dozen results I check to see quality. This cannot have anything to do with Ask.com's recent announcement on NASCAR, so I wonder what exactly is going on here?
