While trying to self-optimize keywords in sedo (using the Preview button pointed out by Seeker - Thanks again!), I came across some pretty quirky links for a few.

Medicine - lots of links for (non-medical) Magazines.
Chemistry - links for Ties and Organic Food.

and weirdest of all...

Denizen (Inhabitant or Resident) - DollHouses!

Could this be why some of the click-through percents are so low???
