Bing Now Powers 30% of US Searches
Bing is doing what no one used to think was possible: knocking search market share points off of Google, and collecting them. — Yes, Bing-powered search in the United States just broke the 30% barrier, clocking in at 30.01% in March according to Hitwise.
Context & Ripple Effects
The climb has been steady rather than sudden: Nielsen had Bing passing Yahoo to become the #2 US search engine back in September 2010, and StatCounter followed in March 2011 with Bing beating Yahoo worldwide. Hitwise's March figure extends that arc to the number that actually matters to advertisers — Bing-powered results clearing 30% of all US queries.
What makes the milestone notable is whose share it comes out of. Hitwise frames the 30.01% as Bing-powered volume, folding Yahoo's query flow into Microsoft's column, which means every tenth-of-a-point gain reads directly against Google — a company that, until this stretch of monthly Hitwise readings, was assumed to be untouchable in US search.
First-order effects
- Roughly three in ten US searches in March ran on Bing-powered results per Hitwise, so Google is ceding measurable query volume at home for the first time in the modern search era.
- Microsoft's multi-year Bing spend gets its proof point: the #2 ranking Nielsen awarded in 2010 has hardened into a 30%-plus share base heading into 2011.
Second-order effects
- Search advertisers gain a genuine second candidate for US auctions, putting pressure on Google's pricing power for high-volume commercial terms where bid competition is thinnest today than it would be in a true duopoly.
- Yahoo's position sharpens from independent engine to distribution channel: with Bing already ahead of it worldwide on StatCounter, Yahoo's query volume increasingly counts toward Microsoft's competitive position rather than its own.
Third-order effects
- If the monthly Hitwise trajectory holds, the US search market settles into a two-supplier structure — a shift advertisers, publishers optimizing for crawl, and antitrust watchers would all have to reprice against the one-engine assumption.
- The divergence between measurers (Hitwise crediting Bing-powered share above 30%, StatCounter counting engines separately) becomes strategically important in its own right, since which methodology wins shapes how competition in search is perceived and policed.
The trend: US search is drifting from a de facto Google monopoly toward a two-engine market, with Microsoft compounding small monthly share gains into structural relevance.
