Since a rapidly growing percentage of web search traffic originates from smart-phones, Google has announced that Google Custom Search now formats search results for mobile phones. Google Custom Search makes it easy for web site owners to add Google-powered search boxes to their sites and Google team posted on their blog discribing in details on how it works.
If you own a website and add a Google Custom Search box to it, when your users access the site on an iPhone, iPod Touch, or Palm Pre, they
can see optimized search results formatted for these devices. When they search on your website, they can be redirected to a Google-hosted Custom Search mobile results page created specifically for your Custom Search engine. If you’d like to serve these mobile results from your own website, you can host your own version of the mobile Custom Search home page.
You can test this out on your phone right now. Here are a few samples: search for user-generated content (e.g. search for “zakumi”) from sites like Wikipedia, or look for more information on Custom Search (e.g. search for “promotion”). As you can see, Custom Mobile Search results can match the look and feel of your own website, and they’ve enabled interactive features, such as label tabs for navigation, as well as promotions. Google promises to add new features soon. To get more details on Custom Search mobile configuration, visit the Custom Search blog.
