Website copywriting mistakes to avoid for better conversions

We recently rewrote the homepage for a client who'd used AI to generate their website copy. On paper, it ticked all the boxes – keywords were in place, the structure was logical – but it read as if it could belong to any business in any sector.

There was no personality, no point of view, nothing that made you want to keep reading. We stripped it back & rewrote it with their actual voice, the way they'd explain their business to someone over a coffee. Conversions improved within weeks.

We've seen the same thing with overly technical sites – one client had a homepage packed with industry jargon & process-heavy language that made perfect sense internally but meant nothing to their target audience. We reframed it around their brand story, the problem they solve & why it matters & the difference it made to enquiries was immediate.

Website copy plays a critical role in how visitors understand your business, trust your brand & decide whether to take action. Even a visually impressive website can struggle to convert if the messaging is unclear or difficult to read.

Research into online behaviour shows that users often scan web pages rather than reading every word, meaning clarity, structure & relevance are essential for keeping visitors engaged. Studies on how people read online show that 79% users skim for key information before deciding whether a page is useful.

If your website isn’t converting visitors into enquiries or customers, small copywriting mistakes may be holding it back. Here are some of the most common website copywriting mistakes to avoid & how to fix them.

Unclear messaging that makes visitors leave

One of the biggest website copywriting mistakes is failing to clearly explain what a business does.

When someone lands on your website, they should quickly understand:

• What your business offers

• Who your service is for

• Why is it valuable

  
  

If this information is unclear, visitors may leave the page before exploring further.

Usability research shows that people typically scan pages looking for clear signals of relevance before committing to reading more. Research on how users read online highlights the importance of clear headings, summaries & structured information.

The solution is simple: prioritise clarity. Headlines should communicate the core value of your service immediately.

Writing for the business instead of the customer

Another common mistake is focusing too much on the business rather than the audience.

Many websites describe internal processes, company history or industry terminology without explaining how those things benefit the reader.

Effective website copy focuses on the customer’s needs, challenges & goals. Government content design guidance emphasises that web writing should always be shaped around the user’s perspective rather than organisational language. Writing for the web guidance from GOV.UK highlights the importance of knowing your audience & communicating information in a way that helps them complete their task.

Shifting the focus from “what we do” to “how we help you” makes website copy far more engaging.

Complicated language that reduces readability

Many businesses unintentionally make their website copy harder to understand by using technical terminology, overly complex language or long sentences.

Clear language improves comprehension & allows readers to understand key information quickly. Plain language writing guidance explains that content becomes easier to understand when writers use shorter words, shorter sections & active voice. 

Using simple language helps visitors process information faster & reduces confusion as they scan a page.

Plain language does not mean oversimplifying your message. Instead, it ensures that readers can understand your content on the first read without unnecessary effort.

Good website copy focuses on clarity, not complexity.

Walls of text that overwhelm readers

Another common issue is large blocks of text with little structure.

Even well-written content becomes difficult to read when it appears as a dense paragraph without headings or spacing.

Accessible design guidance recommends structuring content so it is easy to scan quickly. Accessible text formatting guidance highlights the importance of short paragraphs, meaningful headings & clear layout to improve readability.

To improve readability:

• Break text into shorter sections

• Use descriptive headings

• Add spacing between ideas

  
  

These changes make information easier to digest & keep visitors engaged.

Missing or weak calls to action

Even strong website copy can fail if visitors are not guided toward the next step.

A call to action tells readers what they should do after learning about your service. Without one, visitors may leave the site without taking action.

Calls to action should be:

• Clear

• Visible

• Relevant to the page

  
  

Examples include encouraging readers to learn more about services, request information or order online.

Strong calls to action help turn interest into engagement.

Inconsistent tone across pages

Consistency is an important part of effective website copy. When different pages use completely different tones or writing styles, the brand can feel less professional.

A consistent voice helps build trust, improves readability & strengthens brand identity.

For example, using a friendly, approachable & knowledgeable tone across all pages creates a cohesive experience for visitors.

When your messaging is consistent, readers are more likely to feel confident in your brand.

Avoiding common website copywriting mistakes can significantly improve how visitors interact with your website. Clear messaging, audience-focused content, readable language & strong structure all help guide readers towards meaningful engagement.

Your website should not only explain what your business does but also help visitors quickly understand why it matters to them. When written well, it becomes one of the most powerful tools for building trust & encouraging action.
