Google is announcing today that websites that are optimized for mobile will now factor into ad quality. The company says that last year it began to limit ad serving on smartphone devices if they pointed to landing pages with Flash-heavy content, in order to improve the experience for users. Now the search giant will be considering the mobile optimization of a website as a new factor of mobile ads quality for all AdWords campaigns that are driving mobile traffic.
