Enter your monthly visitors from Google, the growth you expect, the share of visitors who become customers, what each one is worth and your monthly SEO spend. It is an estimate, not a forecast: nobody controls Google's algorithm, so treat the result as a way to test whether SEO makes commercial sense for you.

Quick start: See how much revenue SEO could bring your business. Unlike paid ads, organic traffic keeps coming without ongoing ad spend.

## How SEO ROI Is Calculated

SEO ROI measures how much **additional revenue your SEO investment generates** compared to what you spend. Unlike paid ads, SEO builds compounding value over time.

The core formulas are:

Additional Revenue = New Traffic x Conversion Rate x Customer Value

ROI = (Revenue - SEO Cost) ÷ SEO Cost x 100

### Why SEO compounds over time

With paid advertising, you stop getting leads the moment you stop paying. SEO works differently. The content and authority you build **continues generating traffic for months and years** after the initial investment. This means your effective ROI improves over time as the ongoing cost decreases relative to the traffic you receive.

### Typical timelines

- **Months 1-3:** Technical fixes, content creation, and foundation building. Minimal traffic changes.
- **Months 3-6:** Rankings start improving. You'll see early traffic growth of 20-50%.
- **Months 6-12:** Compounding results. Traffic growth of 50-200% is common for businesses starting from a low base.
- **Year 2+:** SEO becomes your most cost-effective channel as you maintain rankings with less effort.
