Conversion Rate Optimization (CRO) – A Complete Guide

Ever wondered why some websites turn visitors into loyal customers while others struggle to get a single sign-up? That’s where conversion rate optimization (CRO) comes in.

CRO is all about increasing the percentage of people who take a specific action—whether that’s making a purchase, signing up for a newsletter, or clicking on a link. The goal? To make the most of your traffic by turning casual visitors into engaged users.

Different parts of your marketing funnel can have their own conversions. For example, if you’re running a social media ad, a conversion might be a click to your website. But on your product page, a conversion could mean adding an item to the cart.

To get started with CRO, you first need to calculate your current conversion rate. From there, it’s all about testing different strategies to see what works best. Marketers use A/B testing, split testing, and multivariate testing—don’t worry, we’ll break those down for you later.

How to Calculate Your Conversion Rate

Figuring out your conversion rate is pretty straightforward. Just divide the total number of conversions by the total number of visitors, then multiply by 100 to get a percentage:

Conversion rate = (Total conversions / Total visitors) x 100

Let’s say you run an online store. If you had 50 sales and 1,000 visitors last month, your conversion rate would be:

(50 ÷ 1,000) x 100 = 5%

Simple, right? But to get meaningful insights, you need to define what qualifies as a conversion. Are you counting an order as soon as it’s placed, or only after it’s shipped? Are you tracking sessions or unique visitors? Being clear about your data ensures accurate results.

What’s a Good Conversion Rate?

Improving conversion rates takes ongoing testing and optimization. But before you set goals, it helps to know where you stand.

For ecommerce stores, the average conversion rate typically falls between 2.5% and 3%. If your store is converting at 3% or higher, you’re already outperforming many competitors.

That said, the best benchmark is your own historical performance. Track your numbers, test new strategies, and adjust based on what works best for your audience.
