3. Add up the search volumes from all the keywords

5. Customer Lifetime Period (CLP)
The length of time (in months) that your business is able to retain customers. In our example, the CLP is 12 months.
6. Search Engine position
Search Engine position (or ranking) is the position of the targetted keywords on the first page of Google (position 1-10).

8. Projected Clicks:
The projected number of clicks for each ranking position can be calculated as follows: Total Search Volume x Average CTR (from Google search console) = Estimated Clicks. For Example: 2,810 x .50 = 1,405.
9. Prospect to Lead (P2L) Conversions
This is the total number of clicks you have converted into qualified leads. Leads can be defined as contact form submissions, phone calls or subscribers. In our example, we have a 3.5% conversion rate. So, clicks x conversion rate = conversions. Example: 1,405 x .035 = 491 Conversions.
Here are some excellent resources that explain conversion rate & calculations in more detail:
10. Lead to Customer (L2C) Conversions
The estimated number of organic qualified leads that have been converted into paying customers. That is, what percentage of qualified leads does your business generally convert? The estimated conversion rate in this example is 5.5%. Use the following formula to calculate your estimated conversions: Total P2L Conversions x L2C Conversion Rate = Conversions. Example: 491 x .055 = 270 conversions.
11. Estimated Monthly Revenue:
To calculate your estimated monthly revenue at each ranking position, multiply your L2C x Customer Lifetime Value (CLV) divided by Customer Lifetime Period (CLP). Example: 270 x $1000/12 = $22,500 estimated monthly revenue at position #1.
12. Estimated Profit
Take your estimated Monthly Revenue and subtract costs of providing the good or service to find your profit. In our example, the Profit margin is 35%
13. SEO Break-Even Point
Break-even point is the most important calculation for ROI. It’s essential to project how many months it will take to see ROI on your SEO investment.
To calculate the break-even point on your SEO campaign, divide the total SEO investment by the estimated profit from new conversions – Example: 36,000 (3k/mth SEO campaign x 12 months) / 94,500 = 2.6 months to break even at this position.
