Pay Per Click search engines like Google and Yahoo Search Marketing are a great way to get quality targeted traffic.
TIP: Always load your campaigns up with various Ad texts and when you know the percentage of Click throughs each of the ads are getting, delete the ones that aren't performing so well. Usually the higher the Click through rate, the better.
TIP: Having the keyword or keyphrase in the text or headline of the Ad usually increases your click through ratio and relevancy. Always try to add the keywords you are targeting into your ads.
Here are some example PPC Ads you can use for your campaign to start you off. We always advise you create your own Ads as well. You should be able to come up with much better ones, these are only intended to give you a head start.

(We advise you don't use this Ad, create your own for best impact)
I'll say this again because it's important; Always split test more than one Adwords Ad, maybe even 3 or 4 Ads (easy to do from within Adwords) and keep the ones with the highest click through ratios.
