Unlike the online version of Instant Preview, the mobile version doesn’t begin showing results until you’ve finished typing in the search box. Then, like its online big brother, Google shows a list of options, each with a magnifying glass beside it.
Online, when you click the magnifier, you get a pop-up of the preview. On mobile, when you click on the magnifier, previews of the first few pages load on your phone and you can flip through them to find the one you want. No more clicking back and forth.
What this means for marketers is that now mobile searchers will be judging the books by their covers. When customers see a preview of your front page will it pull them in or will they keep on scrolling until they reach your competitor?
