Microsoft's Bing search engine is heading into 2010 in the strongest competitive position it has held against Google in more than a decade. The "decision engine" rebrand from MSN Search and Live Search launched in June 2009 has produced measurable search share gains. The Yahoo Search Alliance — announced in July 2009 and currently moving through regulatory approval — will give Bing a meaningful share of the U.S. search market once Yahoo's search results are powered by the Bing index. The marketing investment under Steve Ballmer has been substantial. The competitive positioning has changed.
This is the working profile of where Bing sits at the start of 2010, what the strategic significance of the Yahoo partnership is, and what the broader implications are for the search and digital marketing categories.
The Bing launch and the decision-engine positioning
Bing launched on June 3, 2009 as the rebrand of Microsoft's Live Search and MSN Search products. The "decision engine" framing — positioning Bing as a search tool that helps users actually make decisions rather than simply retrieving documents — was the central marketing message. The launch campaign was one of the largest single-product Microsoft marketing investments in recent years.
Several product features supported the positioning. Visual search results. Categorized navigation on the left rail. Quick previews of pages without clicking through. Specialized verticals for travel, shopping, and health that surfaced structured information rather than just blue links.
The early reviews from the tech press were positive. Wired, The New York Times, CNET, and the broader technology press gave the launch credit for being substantively different from Google rather than a Google clone. The decision-engine framing landed.
The Yahoo Search Alliance
The Microsoft-Yahoo Search Alliance announcement in July 2009 was the most strategically consequential search-industry agreement in years. Under the terms, Yahoo will use Bing as the search infrastructure for Yahoo's search results, with Yahoo retaining the user-facing brand and the search advertising sales relationship for the combined audience.
The deal is currently moving through regulatory approval in the U.S. and Europe. Implementation is expected through 2010. Once fully implemented, Bing will power the search results seen by both Bing.com users and Yahoo.com users — a combined U.S. market share that approaches 30 percent.
For Microsoft, the deal provides scale that pure Bing growth would have taken years to achieve. For Yahoo, the deal eliminates the cost of operating its own search infrastructure and lets the company focus on its content and advertising businesses. For the broader search category, the deal creates a credible second player against Google for the first time since Google's emergence as the dominant search engine.
The strategic context for Microsoft
Bing is part of a broader Microsoft strategic shift around search, online services, and advertising. Steve Ballmer has been clear in public comments that search is a strategic priority for Microsoft and that the company is committed to multi-year investment to build credible competitive position. The Online Services Division has been investing in engineering, marketing, and partnerships at a level that previous Microsoft search efforts did not receive.
The strategic logic is straightforward. Search and search advertising are one of the largest and most profitable categories in the broader software and online services market. Google's dominance produces revenue and strategic advantages that affect every Microsoft business. Allowing Google to consolidate its position without credible competition would constrain Microsoft's broader strategic options for years.
The Bing investment is not expected to be quickly profitable. Microsoft is treating it as a multi-year strategic investment. The communications work around the launch has been disciplined in framing it that way.
What's working for Bing
Several Bing features and competitive positions are working well heading into 2010.
The visual search results. Bing's image search, video search, and visually-organized results are widely regarded as substantively better than Google's equivalent surfaces in several categories.
Travel and shopping verticals. Bing Travel (built from the Farecast acquisition) and Bing Shopping have produced strong user-experience reviews. Both are categories where the decision-engine framing actually delivers concrete value.
Search share gains. Bing's U.S. search market share has grown from the low single digits at launch to high single digits by the end of 2009. The trend is upward.
The marketing investment. Microsoft has spent substantially on Bing marketing across television, online, and outdoor advertising. The brand awareness lift has been measurable.
What's not working
Several structural challenges remain.
Google's network effects. Google's market position is reinforced by network effects across search, advertising, and the broader Google product ecosystem. Bing's search results getting incrementally better does not automatically produce share shifts.
Mobile search. Google's position on mobile devices — through Android, the iPhone Google search default, and the broader mobile web — is structurally strong. Bing's mobile presence is comparatively weak.
The search advertising relationship base. Most major advertisers have long-standing relationships with Google. Switching ad spend to Bing requires real account-management investment from advertisers who do not always have a strong reason to do it.
The international position. Bing's competitive position outside the U.S. is meaningfully weaker than its U.S. position. Google's international dominance is even more entrenched than its U.S. position.
What this means for digital marketing teams
Three operating considerations for digital marketing teams thinking about Bing.
Bing should be in the search advertising mix. The cost-per-click on Bing is generally lower than on Google for comparable keywords. The Yahoo Search Alliance, once implemented, will give Bing meaningful audience scale. Advertisers who have not been allocating to Bing should reconsider.
SEO for Bing is different from SEO for Google. The two engines weight different signals. Sites that have been optimized for Google will not automatically perform well on Bing. The optimization work needs to be done separately.
The Webmaster Tools work compounds. Bing Webmaster Tools verification, sitemap submission, and the broader technical SEO work for Bing produce incremental benefits that accumulate over time.
What this sets up for 2010
Three structural questions worth watching across the coming year.
Will the Yahoo Search Alliance produce the expected market share gains? Implementation of the alliance is expected through 2010. The actual share gains, the user behavior of Yahoo searchers being moved to Bing-powered results, and the advertiser reaction will all become clear across the year.
Will Google respond? Google has been increasing its own product investment across search, mobile, and the broader product portfolio. The competitive response to Bing's gains will shape the category dynamics.
Will Bing's mobile position improve? Microsoft's broader mobile strategy under Windows Phone is in transition. Bing's integration into the next-generation Microsoft mobile platform will determine how competitive Bing can be in the mobile search category.
The bottom line
Bing is the strongest competitive position Microsoft has built in search in more than a decade. The decision-engine framing is substantively differentiated. The Yahoo Search Alliance will provide meaningful scale. The marketing investment is sustained. The strategic commitment from Steve Ballmer and the broader Microsoft leadership is clear. The category is unlikely to consolidate down to one player as a result. Google remains dominant, but the search market in 2010 looks materially more competitive than it did in 2008. For digital marketers, advertisers, and the broader online category, that is meaningful news.
