Today Google announced “Instant pages” for Google Instant with which their search engine predicts which search result you’re going to click and prerenders that top search result in the background, when you click that page, it will be loaded instantly. Currently, Prerendering enabled for Developer channel of Google Chrome (Chrome 13), you can try Instant pages on upcoming Beta version of Chrome.
Google says prerendering is most useful when a user on multi-page article as user going to click “Next page” for reading, Google orders browser to prerender the page for loading. Website owners need to add a link element with rel of “Prerender “ (ex: <link rel=”prerender” href=”http://example.org/index.html”>) to hint Chrome to render his pages.
