Conversion Rate Optimisation for Small Businesses: Where to Start
CRO means getting more enquiries from the visitors you already have. A practical starting point: what to measure, what to fix first and how to test.
Conversion rate optimisation (CRO) simply means getting more of your visitors to take the action you want, like enquiring or buying. For a small business it’s usually the cheapest way to grow, because you’re improving what you already have instead of paying for more traffic.

Why it matters
If 1,000 people visit your site and 10 enquire, your conversion rate is 1%. Raising it to 2% doubles your enquiries without a penny more on advertising. Compare that with doubling your ad spend, which doubles your costs.
Step 1: Decide what counts as a conversion
Pick the one action that matters most: a form submission, a booked call, a purchase. Track it properly. See conversion tracking in GA4.
Step 2: Find out where you stand
Look at:
- Conversion rate by page and by source
- Where people leave the site and the form
- Device differences, such as mobile versus desktop
- Traffic quality, to see whether the right people are arriving
Step 3: Find the problems
Use a mix of data and real observation:
- Session recordings and heatmaps show what people do. Free tools exist for both.
- Customer feedback. Ask recent customers what almost stopped them from enquiring.
- A five-second test. Show a stranger your page and ask what you do and what they’d do next. See our five-second test.
- A read-through on a phone. It reveals problems you’d never notice at a desk.
Step 4: Prioritise
You’ll find more problems than you can fix. Rank them by likely impact and effort:
- Clarity: can people tell what you do and who it’s for?
- Trust: is there proof?
- Friction: is the next step easy, and the form short?
- Speed and mobile: does it work well on a phone?
- Details: button wording, layout and colours.
Start at the top. It’s tempting to fiddle with button colours, but clarity and proof usually matter far more.
Step 5: Test
If you have enough visitors, run an A/B test: show half your visitors the current page and half a new version, and compare. With small traffic, it’s better to make a clear improvement and compare before and after over a few weeks, rather than chasing tiny differences.
Change one major thing at a time, so you know what made the difference.
Ideas that often work
- A headline that states the benefit in plain words
- A short customer quote next to the main button
- A form with fewer fields
- A button that says what happens next
- A clear answer to “what does it cost?”
- A faster page
Common mistakes
- Testing before the basics are fixed
- Ending tests too early
- Copying another business’s page without understanding why it worked
- Ignoring mobile
- Measuring clicks rather than enquiries
How CRO fits with the rest
CRO works hand in hand with traffic. Better pages make every ad pound go further, as our guide on how to measure marketing ROI explains. It also relies on a clear message, which is where brand strategy comes in.
Frequently asked questions
What’s a good conversion rate?
It depends on the business, offer and traffic. Compare yourself with your own past results and aim to improve steadily.
How much traffic do I need to test?
Enough to see differences in actual enquiries. With lower traffic, make bigger changes and judge over a longer time.
