Your content is your best salesperson
A well-designed but poorly written website converts less well. Conversely, relevant content presented in an inconsistent visual setting does not reassure. It is the combination of the two (the right words and the right presentation) that helps guide a passing visitor towards getting in touch. Online, you only have a few seconds to convince: every sentence and every graphic element has to play its part.
What the figures reveal about online attention
Studies of online reading behaviour give a precise measure of what is at stake, and it is harsher than most people imagine. The figures most often quoted:
Average attention span online: under 10 seconds.
Users who spend no more than 15 seconds on an article: around one in three.
Share of the content actually read by 60% of users: 20% of the page.
Average attention span on a screen: 2 minutes 30 seconds in 2004, 47 seconds today.
Gain in reading time (dwell time) when the reading time is displayed: 15 to 20%.
These figures are not a fatality; they are design constraints. Content that ignores this reality (dense blocks of text, important information buried at the bottom of the page) loses the reader before it has even had the chance to convince.
The rules of effective web copywriting
One idea per paragraph
Users scan a page before they really read it, and 60% of them will never read more than 20% of the content. Short blocks, explicit subheadings and bullet lists make skimming easier and hold attention. A dense block of text discourages the reader before it is even read.
Benefit-led headings
"Grow your online sales" speaks to the reader more than "Our services". Visitors are not looking for what you do, but for what you can do for them. Phrase your headings from the customer's point of view and around their results.
The keyword in the right place
To be found on Google, place your main keyword in the H1 title, the first paragraph, at least one H2 subheading and the meta description, without ever slipping into over-optimisation. Text written for robots is spotted immediately and drives away readers and search engines alike.
The essential information on the first screen
With an average attention span under 10 seconds, the most important information (what you do, for whom, how to contact you) must be visible without scrolling. What readers do not see in the first few seconds, they will probably never see.
Concrete proof
Customer testimonials, examples with figures, case studies, partner logos: social proof removes doubts and makes your message credible far better than superlatives. Show rather than claim.
A clear call to action
Every page should end with an explicit invitation: request a quote, book a call, download a guide. Content that informs without ever inviting action misses the point.
Visual identity as a lever of trust
Substance is not enough: form reassures. A well-managed visual identity signals seriousness and professionalism before a single word is read, which matters all the more because a visitor's judgement is formed in a few seconds.
A consistent colour palette: two or three main colours, applied across all your materials, for a recognisable image.
Legible typography: clean fonts, a clear hierarchy between headings and body text, comfortable spacing.
Documented brand guidelines: they keep the website, social media, emails and printed materials consistent, even when several people contribute.
A brand that stays consistent from one medium to another inspires trust; a brand that changes face on every page sows doubt.
Content and design work together
When copywriting and visual identity are designed together, each page tells a coherent story that naturally guides the visitor towards the desired action. The text carries the message; the design showcases it and makes it credible. This partnership is what separates a website that merely exists from one that performs, a principle we also apply when designing a high-performing brochure website.
Using AI without losing your voice
Artificial intelligence tools speed up content production, but they replace neither your business expertise nor your brand's tone of voice. The right approach is to use them as assistants (to explore a topic, structure it, make suggestions), then to proofread and personalise systematically. Fully automated, unreviewed content is easy to recognise, and it does nothing more to convince your visitors.
Example: before and after on a service page
A generic phrase such as "We offer web solutions tailored to your needs" gives the reader no usable information: not what is done, nor for whom, nor the expected result. A benefit-led, evidence-based version rewrites it as "A brochure website delivered in 1 to 4 weeks, designed to turn your visitors into customers, with technical SEO built in from the start". The second version answers, in a single sentence, the three questions every hurried visitor asks: what, how quickly, with what result.
Long or short: the wrong question
"How many words do I need?" is probably the most frequently asked question in web copywriting, and one of the least useful. There is no universal ideal length: a short, focused sales page converts better than a long, muddled one, but a complex subject with strong search intent can justify in-depth content that will hold attention well beyond the average. Length is not the problem; structure is.
A long article is not off-putting if it is designed for scanning: explicit subheadings, lists, highlighted key points, visual breathing space. Hurried readers quickly find what they are looking for; interested readers can dig deeper. Conversely, three dense paragraphs with no signposts will lose everyone. The real question is therefore not "how many words?" but "does every word earn its place, and does the reader quickly find what they are looking for?".
Measuring what actually converts
Writing to convert only makes sense if you check that it converts. Intuition is misleading: a page you find brilliant may leave visitors cold, and a modest page may be the one that generates the most enquiries. Only data can settle it. Three indicators are enough to start with, all available free of charge through Google Analytics and Search Console: the click-through rate on calls to action, the bounce rate per page and the time actually spent.
These figures tell a concrete story. A page with many visits but a high bounce rate attracts without holding, often because its content does not live up to the promise of its title. An ignored call to action signals an invitation that is too weak or badly placed. Read regularly, these signals turn copywriting from an exercise in intuition into a process of continuous improvement, where each page is corrected in the light of how it actually performs.
Write for the reader, not for yourself
Everything in content that converts comes down to a shift in perspective: stop writing what you want to say and write what the visitor needs to read. Words chosen from their point of view, essential information offered straight away, proof rather than promises, a visual presentation that reassures and a clear invitation to act. None of this is spectacular, but it is this rigour, page after page, that turns a brochure website into a sales tool.
