The Most Important Google Adwords Tips

There are tips about Google Adwords all over the web, and you should go read a bunch of them. For me, however, these were the most important tips.

I haven't confirmed any of these. I'm tried hundreds of tips from around the web. I'm going to figure this out, but right now, nothing is working.

1. Use [exact] keywords only.
2. Use action words like make, build, repair.
