What is SEO ROI?

SEO ROI is the estimated business value of search engine optimization and helps businesses strategize for the future by setting marketing budgets, outlining strategies, and more. SEO’s ROI is calculated with the following formula: (Gain from Investment — Cost of Investment) / Cost of Investment.

How to calculate the ROI of SEO

Now that we’ve talked about the ROI of SEO and why it’s important, how do you calculate it?

Follow these three steps to calculate your SEO ROI today:

  1. Calculate your investment
  2. Track your conversions
  3. Measure your SEO ROI

1. Calculate your investment

To find SEO ROI, you first need to calculate your SEO investment. Once you do this, you can start measuring the revenue generated from your investments.

SEO investments include:

Once you’ve added these expenses, you can calculate your SEO ROI.

2. Track your conversions

Next, you need to calculate the revenue you’ve earned from your SEO efforts by tracking your conversions.

Conversion tracking varies based on what kind of business you run. If you’re an ecommerce or product-based company, you can track conversions based on purchases and online transactions and get an exact revenue amount.

Google Analytics 4 (GA4) is a great way to track conversions.

On the other hand, if you’re a lead-based company, like a service provider, you can track conversions by assigning dollar values to conversion goals, like form submissions.

Google Analytics 4 (GA4) is a great way to track conversions. In GA4, businesses can set up conversion tracking on their sites to effectively monitor conversions and calculate their gains from SEO investments.

By tracking conversions, you can learn which strategies drive the most sales for your business and also identify any conversion killers that may cause you to miss out on revenue.

3. Measure your SEO ROI

Once you’ve calculated the revenue your SEO efforts have generated during a chosen period (most businesses look at specific months or quarters), it’s time to calculate your SEO ROI. Plug in your SEO investment and revenue into the following formula:

(Gain from Investment — Cost of Investment) / Cost of Investment

Once you’ve calculated your SEO ROI with this formula, multiply the result by 100 to get your answer in a percentage.

Let’s take a look at this formula in action.

Suppose a business invested $5000 (Cost of Investment) in their SEO efforts and came out on top with a profit of $50,000 (Gain from Investment) as a result of those efforts. Then our formula would look like this:

(50,000 — 5,000) / 5,000

Doing the math, we’d get 9. Multiplying that by 100, we’d learn that the company’s return on investment was 900%!

What’s a good ROI for SEO?

Throughout all this, you’ve probably wondered, “Is there a good SEO ROI?” Sure, the SEO ROI formula gives us a percentage, but what exactly does that number mean, and is there a specific ROI businesses should aim for?

The answer to those questions depends on your business. Companies invest anywhere from $2500 to $7500 per month on SEO. Sometimes, they can spend as much as $10,000 per month. Not to mention, lead values vary from company to company.

All of this is to say that there is no universal “good” SEO ROI.

That depends on what a business invests in SEO and how much they get back from it. So, when calculating your SEO ROI, set an attainable benchmark percentage for your business, then work your way up as you collect more data and earn more revenue.

What is the formula to calculate SEO ROI?

The formula for SEO ROI is as follows:

(Gain from Investment — Cost of Investment) / Cost of Investment

SEO ROI is calculated as the gain from SEO investment minus the cost of SEO investment, divided by the cost of SEO investment. After solving that equation, multiply your answer by 100 to get a percentage.

How often should you measure SEO ROI?

Businesses typically measure SEO ROI monthly, quarterly, and yearly.

SEO takes time to produce tangible results, so calculating SEO ROI can be tricky since there may be limited data to go on. But as your SEO strategy progresses and your business grows, your cost of investment, gain, and overall SEO ROI will become more defined.

What are the challenges of measuring the ROI of SEO?

Calculating and understanding the ROI of SEO doesn’t come without its challenges. Below are a few common obstacles businesses face when measuring SEO ROI:

  • SEO takes time: Results from SEO efforts don’t appear immediately. Typically, SEO takes three to six months to generate results. That’s why it’s important to set expectations in your organization about SEO’s turnaround time.
  • Gaps between investment and return: Since SEO isn’t time-specific, looking at overall ROI can be tricky initially. While waiting for SEO to kick in, consider monitoring other SEO key performance indicators (KPIs) and metrics like page rankings and organic traffic.
  • Disconnected tech stack: When you have siloed tech, like your website analytics software and your customer relationship management (CRM), it makes tracking SEO’s return difficult. That’s where a platform like MarketingCloudFX becomes helpful!

Are there other ways to measure the success of SEO?

Calculating ROI isn’t the only way to measure the success of SEO efforts. Businesses can also look at their SEO strategy’s performance by monitoring SEO analytics.

SEO analytics is the process of collecting and analyzing raw SEO data to gain a better understanding of your SEO performance. SEO analytics involves tracking data like:

There are tons of SEO analytics tools out there to help measure your SEO performance. By analyzing these SEO KPIs and metrics (and others), businesses can identify opportunities to optimize their campaigns and continue investing in the channels that bring them a positive ROI.
