Conversion rate is the percentage of website visitors who complete a desired action — such as submitting a form, booking a call, or making a purchase.

Conversion rate is calculated by dividing the number of conversions by the total number of visitors, then multiplying by 100. A 2% conversion rate means 2 out of every 100 visitors completed the target action.
What counts as a conversion
Conversions vary by business model. For a service agency, a conversion might be a contact form submission or a booked consultation. For an e-commerce store, it is a completed purchase. For a SaaS product, it might be a free trial signup.
Key factors affecting conversion rate
The main conversion drivers are clarity (does the visitor understand what is on offer?), trust (do they believe you can deliver?), and friction (how easy is it to take action?). Above-the-fold messaging, social proof, load speed, and mobile experience all have measurable impact.
CRO vs. traffic growth
Many businesses focus on driving more traffic before fixing conversion issues. A 1% to 2% improvement in conversion rate is often worth more than doubling traffic — at zero additional acquisition cost. Conversion Rate Optimisation (CRO) and SEO are complementary, not competing strategies.
