Google released the Consumer Barometer a few months ago and I’ve been using it more and more.
It shows you how people search and purchase in several categories and several dozen countries.
For example, US buyers of computer hardware are more than twice as likely to start their research on manufacturers’ websites instead of search engines. If you’re selling computer hardware, it’s much more important for you to be sure that your products are showing up in websites. Make sure the website has a clear navigation path to your product and that your visitors can quickly find your product in the site’s search box. Many large manufacturers’ sites are nearly useless and visitors give up in frustration.
I’m using the Consumer Barometer to set priority for marketing.
