You can have thousands of visitors from Google every month. If no one does anything when they get there, that traffic is worth little more than a dopamine hit from your analytics. That's where conversion rate comes in.
What is conversion rate, really?
Conversion rate is a ratio: how many of the people who visit your website actually do what you want them to do.
The formula is simple:
konverteringer ÷ besøkende × 100 = konverteringsrate %
If 30 people fill out your contact form out of 3,000 visitors in a month, your conversion rate is 1%.
You decide what counts as a conversion. For an e-commerce store, it's obviously a purchase. For a consultant, it could be a booked meeting, an email enquiry, or a download. The point is to measure something that actually means something to your business — not just 'time on page' or 'number of scrolls'.
What is a good conversion rate?
I hear this question often, and the answer is always: it depends. Here are some rough benchmarks based on what I see with small UK businesses:
- E-commerce: 1.5–3% is often good. Niche stores with few products can be higher.
- B2B services with a contact form: 1–3% is strong. Some niches are lower but have a higher value per lead.
- Landing page for a single offer: 5–15% is realistic if the traffic is targeted.
- Newsletter sign-up: 2–5%, depending on where the form is on the site.
The most important thing isn't to compare yourself to an average from an American report. It's to measure your own rate over time and know that the traffic you're getting is the right traffic.
The most common measurement mistake
People often confuse conversion rate with total conversions. It's a dangerous mix-up.
If you have 100 visitors and 10 conversions, your rate is 10%. If you buy ads and get 10,000 visitors and 50 conversions, you have more total conversions — but the rate has dropped to 0.5%. The traffic increased, but the quality dropped.
That's why you must always look at both numbers. A campaign that brings in 10,000 visitors with a 0.5% rate might be a disaster. A campaign that brings in 500 visitors with a 5% rate could be gold.
What actually improves conversion rates
There are countless lists of '200 CRO tips'. Most of them are irrelevant for a small business. Here’s what I see delivering results, in order of priority:
1. The right traffic first
No button colour can save a page where visitors don't need what you offer. If you sell business consulting but get traffic from people searching for 'free template', they will never convert. Work on your keywords, ad copy, and links so that the people who arrive are actually in your target audience.
2. Clarity above the fold
The top part of the page must answer three questions in under five seconds:
- What is this?
- Is it for me?
- What should I do now?
If visitors have to scroll down to understand your offer, you'll lose them. A clear headline, a sentence about the outcome, and one obvious button is often all it takes.
3. Fewer form fields
Every field you ask for is a barrier. Most contact forms don't need a phone number, company name, or 'how did you hear about us?'. Ask for what you need to reply. You can ask for the rest later.
4. CTA text that describes the action
'Learn more' is not a CTA. It's an excuse. 'Book a 20-minute meeting', 'Get the checklist by email', or 'See if we're a good fit' are specific. Visitors should know what happens when they click.
5. Social proof near the decision point
Testimonials, reviews, numbers, logos from well-known clients — placed where people are considering getting in touch. Don't hide them in the footer. They should be near the button, not far away.
6. Mobile friction
Over half the traffic to many UK websites comes from mobile. If buttons are too small, text is too dense, or the form zooms strangely, you're giving conversions away to your competitors. Test your contact form on your own phone right now.
When you have too little traffic to measure
If you have 200 visitors a month, your conversion rate is an unstable metric. One extra enquiry can double the rate. That doesn't mean you should stop measuring — it means you have to interpret the number over several months and be more interested in the trend than in percentage points.
Instead of A/B testing button colours, focus on the obvious:
- Is it clear what you offer?
- Is it easy to get in touch?
- Does the page load quickly on mobile?
- Is there a form or a clear next step on every important page?
When your traffic grows, you can start with more advanced testing. Until then, good UX is the best CRO tool you have.
Conversion rate + SEO = real revenue growth
SEO gets you traffic. Conversion rate determines what that traffic is worth. Together, they're the most profitable thing you can work on.
Let's say you have 1,000 visitors a month, and 10 of them become customers. That's 1%.
If SEO doubles your traffic to 2,000, you get 20 customers.
If you also increase the conversion rate to 2%, you get 40 customers — four times as many, without paying for more traffic.
That's why I never separate SEO and conversion in my own workflow. The two are linked. Better keywords bring better traffic. Better pages get more customers from that traffic. The result isn't just visibility — it's the bottom line.
