### Calculating ROI For Pay Per Click (PPC) Ads

In order to understand the return from PPC ad campaigns, you need to turn know:

- Value of a conversion
- Conversion rate
- Number of clicks
- Average cost per click

Knowing these four variables allows you to calculate the ROI of the ad campaign as a percentage of the overall ad campaign spend.

For our example, assume you spend **$1** per click, and that a conversion is worth **$45**. You convert at **3%**, and obtain **1000** clicks over a given period. Your calculation is then:

**PPC ROI** = ((Total revenue – Total cost) / Total cost) x 100

= (((Value of a conversion x Conversion rate x Number of clicks) – (Average cost per click x Number of clicks)) / Total cost) x 100

= (((45 x 0.03 x 1000) – (1 x 1000))/ (1 x 1000)) x 100

= (1350 – 1000)/1000 x 100

= **$350** or **35% **Time and labor have not been incorporated in creating the PPC ad campaign.

**Alternatively, you can use a quick ROI calculator. Return on Investment (ROI) calculator for blog and business content.**

### Calculating ROI For Blogging & Organic Search

Using the same values for the value of a conversion, **$45**, and a slightly lower conversion rate of **0.5% **because organic traffic is not as focused as a well honed PPC ad campaign, where a blog post takes up 4 hours of time to write – including research, writing, socialising and promotion (non-paid), at **$35** per hour:

**Blog post cost** = Number of hours x hourly rate

= **$140**

= **$85** or approx **60%**

### PPC vs. Organic Search Content

While the numbers in the above calculations suggest that blogging was more successful (having a higher relative ROI), there are several important things to note:

- The PPC ad campaign risked $1000 in cash whereas the blog post had no cash risk
- The PPC ad ROI calculation did not take into account the cost due to labor
- The blog content ROI calculation gave a lifetime ROI, the ad ROI calculation gave the immediate ROI
