If you want to run a free promotion then definitely advertise it. There are plenty of websites that promote free books - here's a list

Personally, I'm not a fan. I just think that the only people who truly benefit are Amazon. They sell Kindles to people expecting free books.
Authors suffer overall because readers expect super cheap and free books.
I can see why people do it, and on an individual level it can be a good thing, but for the big picture I just really dislike it. Just be careful with your expectations. There are a lot of free books out there now, it isn't the fast track to success it used to be. Having said that, I wish you all the luck in the world
