Design to impact on search engine clicks?

The introduction of the Google Preview add-on in the toolbar in Firefox may be about to transform the world of natural search. In the future, click-throughs on search results may not just be based on position and relevance but on the actual appearance of the related website, now viewable via Google Preview.

Currently web users go through a simple decision-making process to choose the right website for them. The search results which are returned are judged by their keyword relevance and the page description, among other factors like whether the user recognises the website URL. However with Google Preview, there is now a new dimension within search which website owners need to be aware of.
