This is not just a list of popular keywords. A keyword can be popular but virtually useless in helping one find a good match ("intelligence", "honesty", "music").
Keywords listed here appear in both positives and negatives multiple times. The discernment value of each keyword is the lower number of the two. For example, a keyword with discernment value of 10 either appears ten times in positives and at least ten times in negatives, or it appears ten times in negatives and at least ten times in positives. The higher the discernment value of a keyword, the more it will help you narrow your choices when searching.
Of course, if a keyword isn't important to you, you shouldn't use it.
