Totally agree with you, that was the case before but not now... Microsoft have slowly caught up and now operate around the 20% search volume mark versus Google's 60%. Here's more info on the market share breakdown: https://www.comscore.com/Insights/Rankings/comScore-Releases-February-2016-US-Desktop-Search-Engine-Rankings https://www.comscore.com/Insights/Rankings/comScore-Releases... The thing to also keep in mind is the %'s will vary according to the preferences of your target audience. For example, our target audience are office based with an admin focus. They tend to use a Microsoft OS, which usually has Internet Explorer and you guessed it - has Bing setup by default! I suspect if you're going after a more "techie" crowd that they're more likely to use Chrome, and therefore use Google for their search needs. Obviously all that really matters are the conversion numbers for your particular app. So I usually recommend that people set up some ads in Bing to mimic what they've setup at Google Adwords. Bing has a Google Adword importer, so just import your Adwords and then run them on Bing for a few weeks to see how you fare. That's what we did for Staff Squared, and we were much happier with the Bing numbers than we had been Google - and still advertise on Bing even now.
