i can type in the keywords in the menu in website-auditor. on every line one word. if i do that, the program will guide me to optimize on SINGLE words, not on a phrase. but a phrase is the term, in which the user searches on google.

Please go to the "Webpages" tab and click "Update -> Your page and competitors' pages". You can enter your phrases one phrase per line:
zauberer dessau
zauberer berlin
zauberer erfurt
zauberer jena etc.
Then you will get optimization score for each phrase, not single words. At the same time the tables will contain scores for single words also.
