Re: Brand new to Adwords: I have adwords gift card for $100 -
Different promotional offers are meant to be used in different ways. I'm afraid I have no idea what kind of gift card you're looking at.
However, in general, AdWords offers are for new advertisers who are encouraged to create an AdWords account and spend a modest amount of their own funds on the program, before they redeem the promotional code for additional (free) clicks on their ads.
The idea, as I understand it, is to encourage new advertisers to "stick with" the program for long enough for it to produce success for them.
If you have more details you can offer or have additional questions, please post again!
