AdWords Optimization - Optimize ROI

The first thing we need to know when we are talking about ROI is what ROI is. ROI stands for Return on Investment. But simply put, ROI is how much money you're making after you pay your advertising costs.

What is Return on Investment (ROI) Analysis?
ROI is a comparison of benefits to cost expressed as a percentage of the original investment. Advertisers measure ROI by taking the advertising cost and dividing over a specified conversion.

Common ways of measuring ROI are:

  • Cost per conversion
    • $10 cost per conversion
  • Conversion Rate
    • Click to conversion ratio of 2.5%
  • Conversion value
    • $10 in sales for every $2 spent on advertising
What is a conversion?
A conversion is a desired action performed by an end user. Tracking conversions allows you to understand the effectiveness of your advertising.

Common Types of Conversions
Acquisitions – Cost per Acquisition (CPA)
Orders – Cost per Order (CPO)
Registrations – Cost per Registration (CPR)
Leads – Cost per Lead (CPL)
Page Views – Cost per Page Views (CPV)
Sales – Cost per Sale (CPS)
Transactions – Cost per Transaction (CPT)
