So, you're planning a blog tour? Let's make this as easy as it can be then.
First things first, get those contacts! There are hundreds of blog sites where bloggers are listed based on what material they are interested in, fiction or non-fiction, and what genre. And if they post teasers or interview authors. Make a thorough list of who you'd like to reach out to and get started. Always be professional, understanding, and personal. (TIP: reach out to the bloggers who have many followers. The whole point of a blog tour is to reach a large audience!)
2) Follow Up.
Usually, one or two follow-up emails are expected. Anything more can be considered harrassing. You don't want to give a bad impression. If they don't respond to your follow-up email, I'd let it go and move onto the next blogger.
Once you have a list of bloggers that will feature teasers from your upcoming release and/or and interview to promote this new novel, get writing dates in a calendar.
4) Stay Organised.
Stay on top of things. Be organized and efficient. Send what needs sending. Promote the blog tour effectively.
5) Thank You.
Don't forget those thank-you emails. Always. If you don't show your appreciation and their blog really helped, they may not welcome you back and consider you an ungrateful author. So do what your parent/s taught you, be polite!
