Seven practical principles for copy that turns website visitors into enquiries and sales, with examples, a simple research method and a plan for your own pages.
Most businesses rewrite their website copy the same way. Someone asks for it to sound more convincing, a writer polishes the sentences, and the conversion rate, the share of visitors who go on to enquire or buy, stays where it was. The words changed, but what they said did not.
What separates high-converting copy from everyone else's is research, not style. Conversion copywriting, meaning copy written to get a visitor to take one action such as booking a call, requesting a quote or buying, works when it reflects what real buyers want, fear and ask, and puts that in front of them at the moment they need it. In practice it comes down to seven principles: be specific, describe the job the buyer needs done, use the buyer's own words, answer objections where they arise, put proof next to the decision, match the message that brought the visitor in, and make the next step feel small and safe.
This matters because copy is one of the cheapest things to change on a page you already pay to send people to. Say 4,000 visitors a month reach your quote page from ads and 2% enquire: that is 80 enquiries. If clearer copy lifts the rate to 2.5%, the same budget brings 100 enquiries, and each one costs a fifth less. Below, each principle comes with an example and a way to check your own pages.
The strongest line on a landing page is often something a customer said first. Before anyone writes a headline, collect the words buyers already use about their problem, the alternatives they considered and the reasons they hesitated. For most small and mid-sized businesses this takes days rather than months, and you already own most of the material.
Sort what you find into three groups: the outcome people want, the worries that slow them down, and the phrases they repeat. Those groups feed the seven principles below. If you sell in several countries, repeat the exercise in each language, because a translated headline keeps your meaning but loses your customers' phrasing.
'We deliver fast' is a claim. 'Order by 2 pm and it arrives the next working day in Austria and Germany' is a fact the reader can check, picture and hold you to. Specific statements are more believable because they sound like something only a business that does the work could say.
Go through your most important page and mark every adjective that a number or a detail could replace: experienced, flexible, affordable, quick. Swap each one for the fact behind it, such as years in the trade, the notice period, the price range or the response time. Every specific must be true and provable: a precise claim that turns out to be wrong costs more trust than a vague one, and misleading advertising is regulated across the EU.
People rarely buy a product for its own sake; they hire it to get a job done, an idea often called 'jobs to be done'. The owner of a manufacturing firm buying accounting software is not really after features, but wants the month's figures ready without three evenings of spreadsheet work. A family buying a heat pump wants lower bills, a warm house and no surprises during installation.
Test your headline by asking whether a buyer would describe their problem that way to a colleague. 'Integrated cloud-based financial management' fails; 'Your monthly figures in two days instead of ten' passes, if you can deliver it. Another quick check is to show the page to someone outside the business for five seconds, then ask what you offer and for whom. Features still matter, but they belong underneath, as the explanation of how the job gets done.
Every company develops its own vocabulary, and its customers rarely share it. A logistics firm talks about end-to-end fulfilment solutions; its customers say they want someone to pack and send their orders so the office can stop doing it. When visitors read their own phrasing on your page, they feel understood before they have even assessed your offer.
This is where the research pays off. Lift phrases straight from reviews, calls and survey answers into headlines, subheadings and button labels, and keep the customer's level of detail rather than smoothing it into marketing language.
The best copy sounds like the voice inside the buyer's head, not the voice of a company trying to sell to them.
Every buyer arrives with doubts. A few are spoken, such as whether there is a minimum contract, but most are not: this will be expensive, the last supplier let us down, we're probably too small for them. Copy that converts names these doubts and answers them in the body of the page, instead of leaving them to a questions-and-answers section that many visitors never reach.
Place each answer where the doubt appears: the price question next to the description of what's included, the size question right after you describe who you work with, the installation worry beside the installation step. If you can't answer an objection honestly, treat that as useful information. The problem may be the offer, not the copy.
Proof means reviews, testimonials, short case examples, recognisable customer names, certifications and guarantees. Most websites gather it on the homepage or a separate testimonials page, far from where people decide. Put your strongest proof beside the enquiry form, under the price and next to the main button, because that is where doubt peaks.
Match the proof to the visitor as closely as you can. A quote from a company in the same sector or of a similar size answers 'will this work for us?' in a way a generic star rating cannot, and 'they replied within the hour and fixed it the same day' does more than 'great service'. Get written permission before publishing a customer's name, photo or logo; a named testimonial counts as personal data under GDPR, the EU's data protection regulation.
Most paid visitors don't arrive on your homepage. They land on a specific page from an ad, an email or a search result, with a specific promise in mind. If the ad says 'office cleaning in Vienna, quote within 24 hours' and the page opens with 'Welcome to our company', the visitor has to work out whether they are in the right place, and many won't bother.
Repeat the ad's promise in the page headline, using the same key words, and keep the offer, price and terms consistent. If you advertise to different audiences or for different problems, give each its own landing page, or at least its own headline. The fix also pays off in the ad account: Google Ads judges landing page experience, including relevance to the ad, as part of the ad quality that affects your ad's position and what you pay per click.
A button that says 'Submit' tells the visitor nothing. 'Get my quote', 'Book a 20-minute call' or 'Check delivery to my postcode' says what happens and how much effort it takes. Next to the button, answer the three questions people have at that moment: what happens after I click, how quickly, and what am I committing to?
Then remove every cost you can. Ask only for the form fields you need for a first conversation, ask for a phone number only if you will actually call, and say what is not required: no payment details, no obligation, cancel any time, if those are true. A visitor who has to guess what they are agreeing to will usually postpone, and postponed decisions are easily forgotten.
A classic A/B test, where half your visitors see each version, needs a lot of traffic to give a reliable answer. If a page gets a few hundred visits and a dozen enquiries a month, such a test could run for a year and still prove nothing. That is not a reason to guess; it is a reason to test differently.
On smaller sites, change one important page at a time and compare four weeks before with four weeks after, with similar ad spend and no seasonal peak in either. Judge the result on enquiries and sales, and on the quality of those enquiries, not on clicks. Keep proper A/B tests for pages with real volume, such as your main paid landing page or a best-selling product page.
