How about when they put a messed up image of the site in the SERPs rather than an accurate image or screen shot? I could see this as being one way at least.
A site I run that looks great when you visit it, but the image they show is an enlarged, blurry portion of a navigation section... (It's the site I'm referring to above.) The image they show as 'the site' is a snip of an image, and not even the full image at the correct size / resolution.
I see this as the biggest problem...that and sometimes having a blank box instead of a picture showing (which could be my ISP I guess).
Seems all my results have a big "blob" of the article image showing in the preview option instead of a full page view like most of the results.
What I'm worried about: clickthru rates will be affected which could affect rank positioning. What causes google to show the "enlarged blob mess" rather than a nice page view like other results? Should I block google from crawling images?
