Website Copy Audit: Clarity, Claims and Calls to Action

A website copy audit reviews whether each page communicates a clear proposition, supports material claims and gives the reader an appropriate next step. Evaluate real copy in context and use analytics or controlled tests to measure outcomes rather than treating writing rules as guaranteed conversion lifts.

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 Over time, the copy becomes a patchwork of different voices, outdated claims, and messages that no longer reflect what the business actually offers or what customers actually care about.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 turns unclear language, unsupported claims and weak task guidance into specific revision hypotheses. Analytics and controlled tests are needed to determine whether a change affects leads, sales or 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 covers headlines, body copy, calls to action, form labels, button text, error messages, navigation labels and other microcopy. Test each element in its journey rather than assigning an expected conversion lift.

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

A headline should identify the page's subject or proposition quickly enough for the intended visitor to decide whether to continue. Evaluate clarity, specificity, source-message match and accessibility rather than relying on an unsupported 80/20 claim.

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

Does it communicate a supported benefit? A benefit can help readers recognise relevance, but quantified outcome claims need evidence and clear conditions. Prefer a precise truthful proposition over an invented result.
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 ask a visitor to continue a task such as submitting a form, starting a trial or contacting the business. Audit the action, consequence and surrounding reassurance together.

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 the action hierarchy clear? Identify the primary task and label secondary routes accurately. Test whether competing actions cause confusion rather than assuming a fixed number is always best.
Does surrounding copy answer material concerns? State accurate cost, privacy, time or commitment information near the action when relevant. Measure the effect instead of predicting it.
Is the action available at the right decision points? Place or repeat a CTA where the journey supports it and verify keyboard and mobile access. Do not impose a universal count.

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 structure — use the shortest structure that preserves accuracy and necessary nuance. Review outliers and comprehension rather than enforcing an average range.
Paragraph structure — break text where ideas or scanning needs change. Rendered line counts vary by viewport and font, so test desktop and mobile pages.
Readability measures — use formulas as comparison tools and test important instructions with intended readers. A universal score cannot establish comprehension or subject accuracy.
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 and substantiated? Verify the speaker, permission, period and evidence behind outcome claims. The FTC's endorsement guidance says testimonials must be truthful and not misleading; atypical results need suitable context.
Do testimonials include permitted attribution? Verify the person's identity, role, consent and any material connection. Use photos and company names only with permission.
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 supportable? State the source, scope and date for user counts or outcomes. Remove figures that the business cannot verify.

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
Sentence and paragraph structure suits the reader and rendered layout
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

Start with pages that combine business importance, user reach and strong evidence of a copy problem. High traffic can raise potential impact but does not replace conversion value, risk or effort.

Review copy after material changes to the offer, price, audience, evidence or legal requirements and use monitoring to set other intervals. For professional support, compare the audit services.
