Mini-test 1: StumbleUpon Ads vs. Adwords

This is truly a very small test - you know I don’t like throwing money at PPC when I can build organic traffic (albeit more slowly), so I kept my expenditures to a minimum.

I loaded $20 into a SUA campaign promoting 6FBS (which has since been migrated here) in the “ecommerce” category. I then set up a $20 Adwords campaign targeting the keyword “make money blogging”.

Here are the results:

StumbleUpon Ads

• Cost: $20
• Visitors: 400
• Cost Per Click: $0.05
• New RSS Subscribers: 47
• New Newsletter Subscribers: 16

Adwords

• Cost: $20
• Visitors: 52
• Cost Per Click: $0.38
• New RSS Subscribers: 21
• New Newsletter Subscribers: 11
