1. Commit to a 30 day plan at a budget of $1.00 a day. This should be very affordable and give you an idea of what works for your niche.
2. Do not go shooting for the moon on your first keyword phrase. Shoot for a phrase that might get 100 or so searches a day. The more popular the phrase the stiffer the competition against Adword pros. Use the free wordtracker tool to dig around and check if there is heavy competition for that phrase. 8 or competitors is too many in my opinion.
3. The title of you ad should be close to your keyword phrase you are shooting for.
4. The next 2 lines is your hook phrase. Try something like...

5. In listing your keyword phrase, put it in brackets.
[your keyword phrase]
This will only show your ad when this exact phrase is searched for.
6. Put your maximum bid at .10 cents.
7. Make sure to only check the Google search button. This will make sure you only get Google traffic.
8. Monitor your results everyday and your average position ranking. You are trying for around the top 5, hopefully the top 3. Also keep tabs on your click through ratio. Ideally you want it around 10% or better. That means you are targeting the right traffic.
9. Check the results on the back end. are they clicking into your BANS store?
Hopefully that will give you a quick look at adwords without blowing a wad of cash. Ideally you should pick up around 200 or more targeted clicks into your store that should convert.
