Everything I have read here seems pretty on point.

The two main things I would emphasize is:

1. Test Market: Don't throw everything out at once. Pick one strategy at a time and spend preferably a few weeks going through different scenarios. It will take some trial and error finding what works best for your product but remember to be patient and set up a schedule.

2. Be Creative: Pick as many related words as you can think of, or that are recommended by a good keyword generation program. Usually the most effective campaigns are the campaigns containing only a few high cost generic keywords. Try to find the keywords that will still pull in traffic but are not as popular as the mainstream ones. It is usually better to have 10 creative $.05 keywords than one $.50 keyword that is too generic to pull in the traffic you are looking for and will result in a sale.

Good luck!
