What is conversion optimization and why is it underused?
Conversion Rate Optimization (CRO) is the process of systematically improving the percentage of website visitors who take a desired action – purchase, book an appointment, fill out a form. Most businesses spend 90 percent of their marketing budgets on attracting traffic and 10 percent on converting it. CRO argues that an inverse proportion often yields higher overall returns.
What is a good conversion rate?
It depends entirely on the channel, industry and what you count as a conversion. For e-commerce, a conversion rate of 2-3 percent is the industry average; exceptional stores reach 5–10 percent. For B2B leads, 1-2 percent of organic traffic filling out a contact form is typical. The most important thing is not to compare with the industry, but to improve your own rate systematically over time.
The Five Fastest CRO Wins
The first and most common win is improving Call-to-Action buttons. Button text like "Send" converts worse than specific text like "Book a free consultation". Button color and placement also matter.
The second is to reduce friction in forms. Each additional field in a form reduces the conversion rate. Only ask for information you actually need at this stage of the customer journey.
The third is to add social proof. Customer reviews, case studies and logos from well-known customers significantly reduce the barrier to purchase.
The fourth is to improve page speed. Every extra second in load time reduces the conversion rate by 7 percent according to Google's own data.
The fifth is to test landing pages. A dedicated landing page for a specific campaign or channel almost always converts better than a generic homepage.
A/B Testing – The Basics
A/B testing involves showing two versions of a page (A and B) to different visitors and measuring which one converts best. That is the foundation of data-driven CRO. Tools like Google Optimize (free), Optimizely and VWO enable this without advanced coding.
