Google has been spotted publicly testing a feature made famous by the SearchPreview for GoogleChrome extension: full-sized result previews. Instead of reading a small excerpt under the link of a result, this feature allows the user to hover over the link and have a popup with a preview of the site. Note that relevant text has been highlighted and enlarged, making it easier to determine if the site contains the information the user is searching for.
This will drastically increase the efficiency of searching with Google. Instead of having to open the link and search for the text on the page, Google shows it to you in a convenient manner. However, there is concern for advertisers and site owners: now searchers don’t visit the site, and ads are not previewed. On top of that, the ads on the side of the results page are blocked by the preview panel.
While this feature is definitely worth implementing, it’s not quite perfect yet. This feature would cause many complaints from advertisers due to lost ad space. If Google can find a way to both preview the ads and avoid blocking their own, this preview mode will be a welcome addition to the search engine.
