Here's the single biggest reason SEO budgets get cut.
Not poor performance.
Poor communication.
SEO is working. Traffic is growing. Rankings are improving. But when the CFO asks "what's the ROI?" the SEO team stares at the ceiling.

The SEO ROI formula
It's simpler than you think:
SEO ROI = (Revenue from organic search - Cost of SEO) / Cost of SEO x 100
The denominator is easy. You know what you spend.
The numerator is where most people struggle. Let's fix that.
How to calculate revenue from organic search
Method 1: Direct attribution
Set up conversion tracking in Google Analytics. Tag organic conversions. Assign revenue values. Google Search Console gives you the search performance data you need.
If someone finds you on Google, lands on your site, and buys something -- that's organic revenue. Track it.
Method 2: Traffic value
Take your organic traffic. Multiply by the CPC you'd pay for those clicks in Google Ads.
If you get 10,000 organic visits/month and the average CPC for your keywords is $3, your organic traffic is worth $30,000/month in ad spend equivalent.
Method 3: Customer lifetime value
If a customer's lifetime value is $5,000 and organic search generated 20 new customers this month, that's $100,000 in lifetime revenue from SEO.
Real numbers from real campaigns
After 500+ campaigns, here are the benchmarks we see:
Compare that to paid ads where ROI is typically 2x-4x (and disappears when you stop paying).
How to present it
