I need a tricky idea to increase the number of visitors to my questions on Super User. Sometimes I ask a question on SU where the answer is really important to me but after a week or more just has 10 to 30 visitors and has no answer; how can I increase the number of visitors to such questions?

P.S: I think of a way that your question always suggest by google to other people who search about. but it need a tricky way to force google crawler and spider to show your question as a top 3.
