Website Copy Audit: Improve Your Words to Improve Conversions

Your website copy is doing one of two things at every moment: convincing visitors to stay and take action, or giving them a reason to leave. A website copy audit examines every word on your site through the lens of persuasion, clarity, and conversion. It is not the same as a content audit, which focuses on performance metrics and SEO. A copy audit is about the quality of the writing itself and whether it moves readers toward a decision.

Most businesses write their website copy once and never revisit it. The homepage was written during the initial build. Landing pages were thrown together before a campaign launch. Product descriptions were copied from a supplier. Over time, the copy becomes a patchwork of different voices, outdated claims, and messages that no longer reflect what the business actually offers or what customers actually care about.

A copy audit reveals these problems systematically. It gives you a clear picture of where your words are working and where they are costing you leads, sales, and trust.

What Is a Copy Audit

A website copy audit is a page-by-page review of every piece of written content on your site with a focus on messaging effectiveness, not SEO metrics. While an SEO content audit asks whether a page ranks and attracts traffic, a copy audit asks whether the words on that page do their job once someone arrives.

The audit examines headlines, subheadings, body copy, calls to action, form labels, button text, error messages, navigation labels, and microcopy. Every word a visitor reads contributes to their experience and their likelihood of converting. Even seemingly minor elements like button text — "Submit" versus "Get My Free Quote" — can shift conversion rates by double-digit percentages.

A thorough copy audit produces a document where every page has specific recommendations: rewrite this headline to lead with the benefit, shorten this paragraph to improve scannability, replace this jargon with plain language, add a CTA above the fold. The output is actionable and specific, not a vague suggestion to "make the copy better."

Copy audits are most valuable for lead generation sites, SaaS companies, ecommerce product pages, and service businesses where the website is the primary sales tool. If your site relies on visitors reading and being persuaded by your words — which is almost every site — a copy audit should be part of your regular optimisation cycle.

Headlines and Value Props

Headlines are the most important copy on your website. Research consistently shows that roughly 80 percent of visitors read the headline while only 20 percent read the body copy. If your headline fails to hook attention and communicate value, the rest of the page is irrelevant because most people will never read it.

During a copy audit, evaluate every headline on your site against these criteria:

Does it communicate a clear benefit? Headlines that describe what you do are weaker than headlines that describe what the visitor gets. "Enterprise Cloud Solutions" tells the visitor about you. "Cut Your Infrastructure Costs by 40% in 90 Days" tells the visitor about them.
Is it specific? Vague headlines like "Better Results for Your Business" could apply to any company in any industry. Specific headlines with numbers, timeframes, or named outcomes are more credible and more compelling.
Does it match the visitor's awareness level? A visitor arriving from a branded search already knows you. They need a different headline than someone arriving from a generic informational query who has never heard of your company.
Is it free of jargon? Industry terms that are obvious to you may be meaningless to your audience. Unless your target buyer uses and expects specific technical language, prefer plain words.

Your value proposition — the core statement of what you offer, who it is for, and why it is better — should be visible within the first screen of your homepage and every major landing page. If a visitor has to scroll to understand what your business does and why they should care, you are losing people at the top of the funnel.

CTA Effectiveness

Calls to action are the moments where your copy asks the visitor to do something: click a button, fill in a form, pick up the phone, start a trial. Weak CTAs are one of the most common conversion killers we find in copy audits.

Audit every CTA on your site using these questions:

Is the CTA visible without scrolling on key pages? If your primary conversion action is buried below three screens of text, many visitors will never see it.
Does the button text describe the outcome, not the action? "Submit" and "Click Here" are generic and uninspiring. "Get My Free Report" and "Start Saving Today" tell the visitor what they receive.
Is there only one primary CTA per page? Pages with competing CTAs — "Buy Now," "Learn More," "Contact Us," "Download the Guide" — create decision paralysis. Choose one primary action per page and make everything else secondary.
Does surrounding copy reduce friction? The lines immediately before and after a CTA should address objections and reassure. "No credit card required" near a signup button. "Takes 2 minutes" near a quote form. These micro-reassurances measurably improve click rates.
Is the CTA repeated at logical intervals? Long pages should include the CTA at least twice — once near the top and once at the bottom. Visitors who read to the end of a page are highly engaged and should not have to scroll back up to convert.

Track CTA click-through rates in your analytics. During the copy audit, note which CTAs have high visibility but low click rates — these are your highest-priority rewrite candidates because the eyeballs are already there but the words are not doing their job.

Tone and Voice

Brand voice is how your company sounds across all written communication. Tone is how that voice adjusts for different contexts — your error messages should sound different from your sales pages, but both should feel like they come from the same company.

A copy audit evaluates voice consistency across your entire site. Common problems we find include a formal, corporate tone on the homepage but a casual, friendly tone on the blog. Different pages sounding like they were written by different people — because they were, over several years by various team members or agencies. Technical jargon on some pages and plain language on others with no apparent logic to the variation.

To audit tone and voice effectively, start by defining what your voice should be. If you have a brand style guide, use it as the benchmark. If you do not have one, the copy audit is the right time to create one. Document three to five voice attributes — for example, confident but not arrogant, technical but accessible, direct but empathetic — and evaluate every page against them.

Pay particular attention to voice consistency between marketing pages and functional pages. Your checkout flow, account settings, error messages, and confirmation emails are all touchpoints where copy shapes the user experience. If your marketing copy is warm and human but your error messages sound like they were written by a robot from 1998, you are creating a jarring disconnect that erodes trust.

Readability

Readability is not about dumbing down your content. It is about respecting your reader's time and cognitive load. Even highly educated audiences prefer content that is easy to scan and digest. Complex sentence structures and long paragraphs do not signal expertise — they signal that the writer did not take the time to communicate clearly.

During your copy audit, evaluate readability using these measures:

Sentence length — aim for an average of 15 to 20 words per sentence. Mix short punchy sentences with longer explanatory ones for rhythm.
Paragraph length — no paragraph should exceed four or five lines on a desktop screen. On mobile, that is even shorter. Long paragraphs look like walls of text and trigger the scrolling reflex.
Flesch-Kincaid readability score — run your copy through a readability tool. Content aimed at general audiences should target a score of 60 to 70 (roughly year 8 to year 10 reading level). B2B content can be slightly more complex at 50 to 60, but never lower.
Subheading frequency — readers should encounter a subheading every two to four paragraphs. Subheadings serve as entry points for scanners and break content into digestible sections.
Use of formatting — bullet points, numbered lists, bold text, and pull quotes improve scannability. Pages that are nothing but dense paragraphs are harder to read and less likely to hold attention.

Test your most important pages by reading them on a mobile phone. If you find yourself squinting, pinching to zoom, or losing your place in long paragraphs, your visitors are experiencing the same friction.

Social proof — testimonials, case studies, client logos, review scores, user counts — is one of the most powerful persuasion tools available. But poorly written or poorly placed social proof can actually hurt conversions rather than help them.

Audit your social proof copy with these questions:

Are testimonials specific? A testimonial that says "Great service, highly recommend" adds almost nothing. A testimonial that says "Our organic traffic increased 142% in six months and we generated 47 new leads in the first quarter" is credible and persuasive. If your testimonials are generic, go back to clients and ask for specific outcome details.
Do testimonials include attribution? A quote from "J.S." is far less convincing than one from "Jane Smith, Marketing Director at Acme Corp" with a headshot. Real names, titles, companies, and photos dramatically increase testimonial credibility.
Is social proof placed near decision points? Testimonials at the bottom of a page that nobody scrolls to are wasted. Place social proof near CTAs, pricing sections, and form fields where visitors are making conversion decisions and may need reassurance.
Do case study headlines focus on outcomes? "Client Case Study: Acme Corp" is a label, not a headline. "How Acme Corp Reduced Customer Churn by 38% in One Quarter" is a compelling reason to read further.
Are numbers used effectively? "Trusted by thousands of businesses" is vague. "Trusted by 2,400+ businesses in 18 countries" is concrete. Whenever you have a real number, use it. Specificity builds trust.

Copy Audit Checklist

Use this checklist as a scoring framework for each page on your site. Rate each item as pass, partial, or fail. Pages with multiple fails are your priority rewrites.

Headline communicates a clear, specific benefit within the first screen
Value proposition is stated explicitly, not implied or buried
Body copy addresses the reader with "you" language, not "we" language
Primary CTA is visible without scrolling and uses outcome-oriented text
Secondary CTAs do not compete with or distract from the primary CTA
Tone and voice are consistent with brand guidelines
No jargon, acronyms, or technical terms are used without explanation
Average sentence length is under 20 words
No paragraph exceeds five lines on desktop
Subheadings appear every two to four paragraphs and describe the section content
Bullet points or lists are used to break up complex information
Testimonials are specific, attributed, and placed near conversion points
Numbers and statistics are used to support claims wherever possible
Objections are addressed proactively in the copy or near CTAs
Microcopy on forms, buttons, and navigation is clear and helpful
Error messages are human, specific, and guide the user toward resolution
The page has a logical flow from problem to solution to action
Copy is free of spelling errors, grammatical mistakes, and broken links

Run this checklist on your homepage, top landing pages, and highest-traffic pages first. These pages have the most visitors and therefore the most conversion potential. Improving copy on a page that receives 10,000 monthly visits will always have a greater impact than perfecting a page that receives 100.

A copy audit is not a one-time exercise. Schedule a review every six months, or after any significant change to your product offering, pricing, or target audience. The words on your site should evolve as your business evolves. If you need professional help with your copy audit, explore our audit services.
