Search Engine Roundtable reports based on a WebmasterWorld thread that Yahoo Search is undergoing an update. Several webmasters have noticed significant changes in the Yahoo Search results. We do not have confirmation from Yahoo on this update, while the last Yahoo update was the first week of this month.
Also, over the weekend we have reports of a Google Toolbar PageRank update. We have discussion around this update at our very own Sphinn forums. This toolbar PageRank update does not seem to be accompanied by any actual search update at Google, which is now normally the case.
I coined both these updates the Rosh Hashanah 5769 updates, since tonight is Rosh Hashanah, the Jewish New Year, year 5769.
