Here I found an interesting story “This Tiny Change to Your Website Will Get You Way More Clicks

The author says it is more effective to use nouns (Be a voter) rather than verbs (Vote now!) The meaning of these phrases is almost the same but using noun on your phrase is more effective than using verb.

Yes it may true even for Japanese and it sounds something new (fresh) to say Be a voter rather than Vote now!

How about in Vietnamese???
