I'm confused as to what is the best method for metadata keywords? Should I capitalize appropriate words for my keywords? Or would it be best to leave all words uncapitalized? Or should I include both an uncapitalized and appropriately capitalized version? Which of the following methods would be best for metadata keywords: Method A: Transformers, Michael Bay, review Method B: transformers, michael bay, review Method C: Transformers, Michael Bay, transformers, michael bay, review I'm also confused if it would be best to include variations of the keywords: Transformers, Transformers review, Michael Bay's Transformers, Michael Bay, review
