I started realizing as I was doing searches that it would be very helpful to know what concepts are discussed on each of the pages that rank for a given set of keywords before I actually visited the page.
For instance, if I did a search for “chicken soup recipes” it would be nice to know if the ranking page also talked about “chicken broth” and “chicken gumbo” (incidentally, one of them does). That information might influence whether or not I click-through.
Also, when searching for “alternative search engines” it would be nice to know at least a few of the other sites that the resulting page links out to. That way I could get a quick idea of whether or not the resulting page talks about some of the alt search engines I’m not already familiar with.
Since I thought both sets of information would be useful, they are now displayed on the results pages. Please post a comment and let me know if you find them useful as well (or not).
