Can SE's results page be improved via images? As it is known to all that sometimes SE's return results that is irrelevant to the queried terms,which is very frustrating. Is there any way,so that the visitors are able to know, they are going to visit their desired destination page,before clicking on the link of SE's result page?
i think it can be cheated with blackhat seo i think the most relevant are the top 3 or 10 or have to do several searches before you arrive on the correct one.
Using black hat, hiding txt and many more... (You might get penalized I suggest not to use it) Bots cant read images content though alt tags can be red.
As I understand it your question was "Would it be useful for a search engine to show a screenshot of the page so a searcher can see it before they click on the link?". Ask.com use this and I don't like it. Keep the interface simple and it works best.
A thumbnail would not show the surfer what is on the result's page cuz it's too small. It only takes one click to view a search result, you make it sound like a lot of work. The SEs already display a "title" and description for each result. Maybe you could try more specific searches? Bompa
