Can you help me with a blog tour?

I am planning a blog tour for my book that is coming out this May. Only, I have no idea how much is enough or too little. As it is, I've scheduled eleven days. But when I look at Ciara Knight who is going on tour later this month for the fabulous Curse of Gremdon (I can say this because I read it), she has got a lot of time blocked out (I think the entire month).

So, I'm asking you knowledgeable writers out there...what is the perfect amount of days to use for a blog tour? Do they need to be spaced apart or can they be Monday thru Friday? Are you expected to give out something like an Amazon gift card or a book or is it okay not to give out anything?

I'm also looking for three more people who would like to host me to fill out the schedule I have (unless it ends up not being enough or too much). If you would be willing to help me with a blog tour, please say so in the comments :)

You can check the schedule I have at this link or by clicking the tab above.

Have a great Tuesday.
