Whatever you say about Google, you can’t accuse it of resting on its laurels. Not content with dominating the online search, it is constantly tweaking and tuning the search experience and has now brought one of these tweaks to mobile phones.
Google Instant Previews launched on desktops last November and provided users with a cached view of the first page of each search result when they clicked on the magnifying glass icon. Google has now rolled out the service to both Android (2.2 and higher) and iOS (4.0 and higher) platforms.
Searching for something on a mobile can be tricky, but with Instant Previews you can spot pages with the right content without having to navigate back and forth between websites and search results. And when the mobile version of a website is available, it’ll show you a preview of the mobile page. To use Instant Previews on your mobile device, do a search on www.google.com and tap on the magnifying glass next to any search result. A side-by-side comparison view of the webpage previews for the first page of search results will appear.
Google Instant isn’t necessarily that useful on a mobile phone, due to typing errors on small keyboards and a cramped screen. However , with Instant Previews, the separate cached pages of the search results which can easily be navigated on your mobile could help save bandwidth and make finding exactly what you are looking for a lot easier.
