I was surprised to see a thumbnail previews of websites in my Google search results this morning. It's worth sharing that Google has added one more nice search enhancement after Instant. Google users will now be able to see a larger thumbnail preview of pages they're going to visit beforehand in the right hand side. They can then decide right there whether to visit the page or not. Needless to mention, Bing has been having somewhat similar feature right from the start. See how a query on PC Security keyword shows up in results now. This may not go favorably for Google sponsored results since the thumbnail may overshadow sponsored results of the right hand side completely. I'm not sure if sponsored results will also get thumbnail previews. Last checked, they were not displaying any for such results.
