Comprehensive Conversion Rate Calculator

Why These Levers Multiply

Most businesses pull one lever at a time. They either invest in SEO and ads to get more traffic, or they hire a CRO agency to improve conversion rates. Both work independently. But when you pull both at the same time, the gains multiply, they don't just add.

Here's the simple math: if you increase conversion by 50% (say from 2% to 3%) you get 50% more leads from the same traffic. Good. Now if you also increase traffic by 50% (say from 10,000 to 15,000 visitors), you get 50% more visitors all converting at the higher rate. The combined effect is 1.5 × 1.5 = 2.25x — a 125% total increase, not 100%.

CRO first, traffic second. Fix the bucket before you pour more water in it. Then turn on the hose.

What "Realistic" Looks Like

In the calculator above, we default to a 50% improvement on each lever. That might sound aggressive, but it's actually conservative for most sites we audit. Here's what we typically see in the first 90 days:

• Conversion rate lift: 30–80% improvement is normal when starting from an unoptimized site. Moving from 2% to 3–3.5% is very common.
• Traffic increase: 20–60% lift through SEO fixes, better ad targeting, and improved Quality Scores (which reduce CPC and increase impression share).
• Combined effect: 1.5x to 2.5x total lead volume within 90 days. That's not theory — we have the case studies to prove it.

The Order Matters

Notice in the calculator that CRO improvement alone already produces a significant lift — without spending a dollar more on traffic. This is why we always optimize the site first. Every dollar you spend on ads after CRO improvements is worth more because each visitor is more likely to convert.

Spending more on ads before fixing your conversion rate is literally paying more to waste more. Fix the foundation, then scale.
