I have used different promo tools over the years to try to get the word out about my books. Help a reporter is an email newsletter that works on the principle that we all have an expertise or knowledge that some reporter may need. In return for that expertise, you get free publicity. It’s interesting to read through some of this stuff, and it has been around a while.
A more recent tool is blogdash. It can help you monetize your blog if that is your deal.
I like it when authors get together to help publicize.
Marketingforromancewriters has an email group as well as the website that is a great help when you are needing promo ideas and help. MurderMustAdvertise a simillar group for mystery writers, has some good advice for writers but is a little less hands on.
Sometimes we all just need a little help.
