Step-by-Step Guide to Using the SEO ROI Calculator
Here is how to use the A Calculator Online‘s SEO ROI calculator to help you set realistic expectations.
We understand that no one can guarantee results before execution, so it’s difficult to know exactly where you’ll be in the coming months.
Still, you should either review your past growth rate or ask your SEO consultant or agency to provide data on what they believe is achievable.
They can offer estimates based on their experience. For example, if you’re asking them to rank for an easy keyword and have a sufficient budget, they can give you a close estimate of the timeline, expected traffic, and potential conversions based on search volume.
Step 1: Choose Your Calculator Type

What to do:
- Click Standard if you’re a small/medium business or starting SEO. Especially when you get direct sales like an e-commerce store, a consultant’s website, a SaaS company, or a local business.

Major Difference Between the Standard and Enterprise SEO ROI Calculators
You might be wondering what the difference is between the Standard and Enterprise SEO ROI calculators, and which one is the right fit for your business.
Here’s what you need to understand to make the right choice:
Enterprise SEO Calculator:
Enterprise and B2B companies usually have long and complex sales cycles. Multiple touchpoints are involved, making conversions harder to track directly from traffic.
There are two key conversion steps in this process:
- Leads generated from organic traffic
- Actual customers converted from those leads
Because of this, the lead-to-customer conversion rate is essential to calculating ROI accurately.
Additionally, many enterprise-level companies have hybrid SEO systems:
- An internal SEO team
- In-house content creators
- External SEO consultants or agencies for execution or expansion
If your sales process is complex or involves multiple departments, the Enterprise SEO Calculator is a better choice.
Standard SEO Calculator:
This version is ideal for businesses that generate direct sales from SEO efforts.
Use this if:
- You run an e-commerce store (e.g., Shopify, WooCommerce)
- You sell SaaS subscriptions through your site
- You track conversions or sales directly from website traffic
Even if you also have a blog and collect emails, if most of your revenue comes from direct conversions, the standard calculator is a good fit.
Tip: If you use email marketing and know that some blog readers convert later, you can add a small buffer (like +1%) to your conversion rate to reflect that influence.
For instance, many e-commerce businesses see conversion rates around 2–5%, depending on the product and site experience.
Tips for Best Use
- Use real website data or realistic estimates for accuracy.
- Remember, SEO takes time — the timeframe input helps you model this.
- Use the Enterprise calculator if your SEO involves complex funnels or multiple cost factors.
