Google has launched GoMo, an initiative to mobilize websites for better user experiences. It features compelling graphics, tips about why and how to go mobile, case studies and a site tester, as well as a list of featured paid vendors who make mobile sites.

Google reports that 61% of users are unlikely to return to a site that's not mobile friendly, but user engagement increases by 85% with a mobile-friendly design. That trend is appearing around the world; consumers are way ahead of businesses on mobile. GoMo is a concerted effort to help companies catch up.

As we reported when we discovered GoMo pre-launch yesterday, it's in Google's interest to get businesses onto the mobile Web as an advertiser and a commerce platform. It offers a free mobile site builder as part of Google Sites to build quick, standalone sites. But GoMo is a major marketing effort to get businesses to buy top-quality mobile sites.

The directory of mobile site developers offers browsing by service type (do-it-yourself or full-service), annualized cost and timeframe for build. Google's own free Site Builder is listed, along with a handful of featured shops.
