Ask HN: Cheap AdWords for a startup?

Well, your ad position is determined based on your bid amount and your quality score.

Your quality score is based on ad text, keywords, landing page quality, bounce rate, and other factors.

So, I'm not sure what you're asking for (cheap keywords?), but it doesn't work like that...

It's going to be hard to find a CPC rate in the pennies as well as get good conversion rates. However, one thing you could do is target a smaller market.

For instance if you are selling a product marketed to auto body shops; start with say Dallas vs. the entire US.

If someone had a profitable niche with low CPC in adwords, they wouldn't share it.

Target a poor country, not the US. That will cut down your CPC dramatically.
