Yahoo updates its algorithm · 29 November 04

Observers just noted shifts in Yahoos search results pages for competitive keywords.

Yahoo has been serving up basically two sets of search results. Yahoo has been testing out a new algorithm that assigns more weight to those pages that have been listed in the Yahoo Directory. Reasoning for this could be that Yahoos only competitive advantage is its directory.

Members at Search Engine Watch Forums were noticing different results based on the case sensitivity of the keyword phrase.

Tim Mayer, directory of Yahoo product management search technology, answered this anomaly by saying that the document was not being returned in one cluster and it was being returned in another but it absolutely had nothing to do with case sensitivity.

Interesting to note these two threads with Tims response – might be some correlation.
