I do the same thing. I also have a word document for my portfolio that has detailed descriptions of each photo so in my portfolio book I can have the image on the right side and the description on the left (in document protectors) The way I generate my key words is.:
I google the subject and get the description (they use a lot of keywords) then I copy paste the description onto a word document for my portfolio. Then I copy paste the description onto my keyword document and delete the extra words and keep the keywords I want. Another cool thing about Microsoft word is it has a review tab and allows you to do a word and character count too! hope that helps too. I noticed that if I put the keywords into lightroom it keeps the keywords when you upload your photos to FAA but they aren’t so good and some of the keywords get deleted.
