In the article, they cite Nielsen numbers and claim that the number of searches that google gets is declining, month over month for the last quarter. Here's what they write:
Some evidence suggests a search slowdown. The average number of daily Google searches in the U.S. fell from 4.4 million in October to 4.2 million in November to 4 million last month, says Nielsen.
Holy Dr. Evil, Batman! How order of magnitudinally challenged can one be?
Now the actual Nielsen release covering search isn't too hard to read, but apparently the reporter at IBD isn't good at maths.
Google gets at least 4 BILLION US searches per day you idiots! See the (000) in the table column header? Not 4 million.
Thank goodness those professional business journalists have editors to catch these minor over sights...
Seriously if you want cogent analysis on search engine share, Danny Sullivan is one of the few games in town. Be sure to read the caveats.
