Bing steady, Yahoo dropped

[GilReich]

For weeks, Yahoo consistently contributed just over 80% of what I got from Bing. Suddenly for the last two weeks the Yahoo and Bing graphs diverged, with Yahoo traffic dropping to 50% of Bing's. Any ideas? Did Yahoo make any deals with companies to give them better ranking? Have they suddenly started adding more ads above the fold? Any thoughts? Thanks

Yahoo recently changed how they process searches, and searches are now all done through a secure server.

This article goes into more detail: http://searchengineland.com/yahoo-search-goes-secure-182343

"By default, searches on Yahoo.com are now done through a secure server. That means more protection for searchers but less data for search marketers about how they are receiving traffic. Most visits from Yahoo done via search will appear as if someone came to a site directly. As a result, Yahoo’s apparent popularity as a traffic driving source will appear to plunge."

More traffic from Yahoo will now appear as "direct" instead of from Yahoo. Perhaps you've seen an increase in direct traffic?

Great answer, thanks!
