How to Measure Organic Sales Growth from SEO

If you're running a business online, chances are you're already investing time and money into search engine optimization (SEO). But here’s the big question: How do you measure organic sales growth from SEO? If you’ve ever wondered whether all your efforts are actually bringing in sales—not just traffic—then this guide is for you.

I’ve spent a lot of time helping businesses track the real value behind their SEO efforts, and from my experience, it all comes down to understanding the right data, tools, and strategies.

Let’s walk through it all step-by-step in simple language.

What Is Organic Sales Growth?

Before diving in, let’s get clear on the term. Organic sales growth means an increase in sales that comes directly from unpaid search results—when people find your site through Google or Bing and make a purchase.

You're not paying for ads. Instead, you're growing naturally, thanks to high rankings and solid content.

Why It’s Important to Measure It

In Ecommerce SEO Service Tracking organic sales growth helps you:

• Understand which SEO tactics are working

• Justify your SEO budget

• Fine-tune your content and strategy

• See the real return on investment (ROI) from your SEO campaigns

And in a world driven by data, knowing what’s moving the needle matters more than ever.

How to Measure Organic Sales Growth from SEO

Here’s the step-by-step method to do it right:

1. Set Up Accurate Conversion Tracking

The first step is making sure you’re actually tracking sales correctly.

Use Google Analytics (GA4)

• Connect your website to Google Analytics if you haven’t already.

• Set up eCommerce tracking for full insights into product performance.

• Track conversions like:

  • Purchases

  • Lead form submissions

  • Phone calls (using tools like CallRail)

    
    

2. Identify Organic Traffic Sources

Once conversions are tracked, dig into where that traffic is coming from.

Use Source/Medium Reports

• Go to Reports > Acquisition > Traffic acquisition

• Filter by organic to see search-based traffic only

• This will show:

  • How many users found you via search

  • Which pages they landed on

  • How much revenue came from those visits

    
    

3. Compare Time Periods

You can’t measure growth without comparing two periods.

• Choose two date ranges:

  • Last 30 days vs previous 30 days

  • This year vs last year

• Look at:

  • Number of organic sessions

  • Conversion rate

  • Total sales revenue from organic traffic

Tip: Always account for seasonality and industry trends when comparing.

4. Calculate the Growth

Let’s keep this super simple.

Formula:

Organic Sales Growth = ((Current Period Sales - Previous Period Sales) ÷ Previous Period Sales) x 100

Example:

• January Organic Sales = $10,000

• February Organic Sales = $13,000

• Growth = (($13,000 - $10,000) / $10,000) x 100 = 30%

That’s a solid increase!

5. Use Google Search Console Insights

Google Search Console gives deeper insight into:

• Keywords driving traffic

• Top-performing pages

• Click-through rate (CTR) changes

• Impressions and average position

These metrics can help explain why sales are going up (or not).

Sometimes, organic traffic plays a role in a multi-touch journey.

Use Assisted Conversions in Google Analytics

• Go to Conversions > Multi-Channel Funnels > Assisted Conversions

• This shows:

  • How organic helped even if it wasn’t the final touch

  • SEO’s role in the full customer journey

This is important for products with longer sales cycles.

7. Align Content with Buyer Intent

Not all organic traffic converts the same. Focus on creating content that speaks to the intent behind search queries.

• Target:

  • Informational keywords (e.g. “best budget laptops for students”)

  • Transactional keywords (e.g. “buy budget laptops online”)

Matching content to intent boosts both conversions and satisfaction.

8. Monitor SEO KPIs Regularly

Besides revenue, track:

• Bounce rate

• Time on site

• Conversion rate from organic sessions

• Pages per session

• Keyword rankings (use tools like Ahrefs, Semrush, or Moz)

These help paint a full picture of what’s working.

9. Report Results Clearly

Create simple, visual dashboards using tools like:

• Google Looker Studio (formerly Data Studio)

• GA4's Explore feature

• SEO tools with built-in reporting

Show revenue growth, top pages, and keyword trends. Stakeholders love to see proof.

10. Be Patient (But Stay Consistent)

SEO isn’t instant. But over time, it builds a steady pipeline of qualified traffic.

• Review performance monthly

• Adjust your strategy as needed

• Keep optimizing pages and targeting new keywords

  
  

Semantically Related Keywords You Should Know

To get more visibility, you’ll naturally want to include semantically related keywords like:

• SEO ROI

• Organic conversions

• Non-paid traffic sales

• Search-driven revenue

• SEO performance metrics

• Growth from Google search

• Content marketing ROI

These help Google better understand your topic using NLP (Natural Language Processing), which is key to RankBrain and voice search success.
