In its second week since launch, Microsoft’s new Bing search engine has continued its steady growth, according to comScore. Bing is up about 3 percentage points in both average daily penetration among US searchers and their total share of search results pages (which indicates the percentage of all actual searches, though is not an exact measure), compared to the week prior to launch. Bing now has 16.7% searcher penetration and a 12.1% share of search results pages among all US workday searches. Those numbers are also both up compared to its first week in the wild.

Microsoft has been on an advertising blitz since their new search engine’s launch, spending a reported $80 to $100 million on a campaign to push Bing. That has, at times, ranged from clever to downright bizarre. But the early numbers indicate that Microsoft’s advertising push is at least driving a measurable number of curious searchers to Bing.
