I have a free coupon worth 50 $ of adwords should i use it to advertise my site http://weirdostuff.com
I used my $50 adwords coupon a while back to promote CoreLogo – logo and graphic design
from what I can tell it resulted in 3 sales direct from adwords advertisments. At the cost of $80 per design, it was easily worth it.
If anything it will atleast drive some traffic to your site.
