This wordle site tells you how good a choice that your first guess is, and gives a link for you to try to find better words. This is somewhat annoying and also annoying that I have not been able to find the top word. The best I could do is “stare”, which is rated 5.

The scoring is apparently based on how frequently the letters occur in words and also how many times they share the same position. The position does make a difference. I tried “tears”, which has the same letters as “stare”, but was ranked at 330.
