How to put in use the Adwords Voucher?

So I got a $100 voucher for Google Adwords, can you suggest me some good way by which I can put this into use ? (and may be learn something new)

I have not used Adwords before and I don’t run affiliate websites so I don’t think that it would be worth while to advertise my current websites using adwords

any suggestions ?

Start by making a campaign on a variety of keywords closely and not so closely related to your brand. You can expirement with different offers to entice visitors from promotions to good content to value, play with demographics, even try a few content sites to target out too.

There’s lots of options but stay focused on things that are in your niche and see how you succeed. If you get a good return you can keep investing.
