What is Conversion Rate Optimization (CRO)?
Definition
Conversion rate optimisation (CRO) is the systematic process of increasing the percentage of website visitors who complete a desired action, such as booking a call, requesting a quote or buying, by finding out why people do not act and fixing those barriers with evidence.

How conversion rate optimisation works
Conversion rate is simple arithmetic: conversions divided by visitors. If 2,000 people visit your quote page in a month and 40 submit the form, the rate is 2%. CRO aims to move that number by improving the experience rather than buying more traffic.
The work follows a loop. First, research: analytics show where people drop off, session recordings show what confuses them, and short surveys or customer interviews explain why. Next, form a hypothesis, such as "mobile visitors abandon because the form asks for an address before showing any pricing." Then change something, ideally measured with an A/B test when traffic allows. Keep what works, learn from what does not, repeat.
Example: an HVAC company finds that most visitors to its furnace replacement page leave without scrolling. Moving financing options and a clear call to action above the fold, and adding real installation photos, gives hesitant buyers the reassurance they were looking for.
Why it matters for your business
CRO multiplies the value of every other channel. If your landing page converts twice as many visitors, every ad dollar, SEO visit and social post produces twice as many leads. That often makes it cheaper than chasing more traffic, particularly once advertising costs climb.
It also replaces opinion with evidence. Instead of debating colours in meetings, you watch how customers actually behave and act on it. Our landing page best practices are a practical starting point for the first round of fixes.
Common mistakes
- Copying "best practices" from other sites without checking whether your visitors face the same problems.
- Optimising for micro-conversions like clicks while the real outcome, qualified enquiries, stays flat.
- Ignoring speed and mobile usability, which quietly undercut every other change.
- Declaring winners from too little data.
- Treating CRO as a one-off project rather than an ongoing habit.
Frequently asked questions
What is a good conversion rate?
It depends heavily on industry, offer, traffic source and what counts as a conversion. A page selling a high-value service will convert differently from a free download. Your own trend over time is a more useful benchmark than an industry average.
Where should CRO start on a small business website?
Start with the pages closest to revenue: quote forms, booking pages, product and checkout pages. Fix obvious friction there before polishing blog posts or the about page.
Is CRO only for e-commerce?
No. Service businesses benefit just as much, because their conversions (calls, bookings, forms) are often few and valuable, so each improvement shows up quickly in the sales pipeline.
