You can easily set up your Google Adwords account Google Adwords.

Once you've signed up or logged in, create a new campaign:

• Step 1: General > Name you Campaign: (Name this your product offering).
  
• Step 2: Location and Languages > Choose "Let me choose" - You'll have to type each individual country to choose your ideal geographic regions. However if you're looking to target English speaking audiences simply select languages, and click the English check box only.
  
• Step 3: Networks/Devices > Choose "Let me choose" - Click "Google search" you can advertise on search partners of the display network but in my experience you are more susceptible to click fraud or unqualified click throughs who will simply bounce due to a lack of interest in your product. Google search offers the highest quality in traffic.
  
• Step 4: Bidding and Budget > Choose "Focus on Clicks", Manual bidding for clicks. This means you will be setting a max bid for each individual keyword based on their competition. In the long run this gives you the best value per click. You will set your max CPC bid in the keyword section later. Then set your campaign budget, this is the amount you are willing to spend per 24 hour period - we recommend starting at $10 per day.
• • +Delivery Method > I usually use the default here "Show ads evenly over time".
• Step 5: Advanced Settings: You can explore the advanced setting to experiment if you want to build out your campaign in unique ways. I suggest this only for intermediate Adwords users.
  

NOTE: Be sure to pause your campaign until this milestone is complete.
