I am ranking 3rd for a keyword which is a term in our industry. In one spelling of the word I am 8th and in another I am 3rd.. I have both spellings in my optimisation such as Keywords Keyword, Key Word, Key Word Jobs, As you can see there is a space between Key and Word in one interpretation of the term. How come I am 8th for Key SPACE Words and 3rd for KEYWORD. Do I need to optimise for both variations of the same word seperately?
