A visitor should be able to identify the service, intended customer and next action quickly, but ten seconds is a diagnostic rather than a universal conversion rule. Show the page to someone unfamiliar with the business, then ask what the company does, who it serves, where it operates and what they would click next. Rewrite vague claims and hierarchy where answers are unclear.
A first-time visitor should not need a company meeting to understand the homepage.
The “10-second test” is useful because it forces the business to check whether the main message survives a quick first impression.
Ten seconds is not a universal conversion benchmark. Use it as a clarity diagnostic.
Test someone who does not already know the business
Do not run the test with the founder, sales manager or designer who wrote the page.
They already know what every phrase is supposed to mean.
Show the first screen to someone who fits one of these groups:
- potential customer unfamiliar with the company;
- colleague outside the project;
- friend who understands the industry only broadly;
- new employee before onboarding.
Let them view the page briefly, then hide it.
Ask four concrete questions
Ask:
- What does this business sell?
- Who is the service for?
- Where does the business operate, if location matters?
- What would you click if you wanted to enquire?
Do not help them with the answer.
Write down the words they use.
If three people interpret “integrated digital solutions” differently, the phrase is not doing enough work.
Put the service in plain language
A strong heading often contains the category a buyer recognises.
Examples:
Weak:
Building tomorrow’s possibilities.
Clearer:
Website design and brand identity for South African service businesses.
The clearer version can still carry personality in the supporting copy and design. It simply identifies the offer first.
Explain the customer problem beneath the heading
The supporting sentence should add meaning rather than repeat the heading.
For example:
We design and rebuild the pages people use before they call, email or WhatsApp your team, with clear services, mobile usability and lead measurement built into the project.
That tells the visitor what the website work is trying to improve.
Avoid stacking three abstract claims:
Innovative. Strategic. Transformative.
Those words may be true, but they do not help a new visitor classify the service.
Show the audience when it changes fit
You do not need to say “for everyone”.
Specificity can improve qualification.
Examples:
- for service businesses;
- for industrial companies;
- for South African SMEs;
- for ecommerce brands;
- for multi-location clinics.
Only include the audience if it reflects the actual offer.
Do not narrow the wording to a niche the business does not serve simply because niche copy sounds more focused.
State location when location changes the decision
A local business should make geography easy to understand.
Examples:
Pretoria-based, serving clients across Gauteng.
or
Walk-in clinic in Villieria, Pretoria.
A remote software business may not need a location in the hero at all.
Use location because it matters to the customer, not to fill a keyword slot.
Give the first screen one obvious primary action
If a visitor understands the offer but cannot tell what to do next, clarity is incomplete.
Choose one primary CTA:
- View website pricing;
- Describe your project;
- Book an assessment;
- Call the branch;
- Ask on WhatsApp.
Secondary actions such as “View our work” can still exist, but the main commercial route should be visually clear.
Check whether the image helps or distracts
A hero image should support the offer or brand impression.
Ask what the visitor learns from it.
A real project, product, person or relevant visual system can add context.
A generic laptop stock photo may add decoration without explaining the service.
Do not place important service information only inside an image. Text needs to remain readable and accessible.
Remove internal language
Companies often use words customers do not.
Examples:
- solution architecture;
- ecosystem enablement;
- integrated excellence;
- full-spectrum innovation.
Some industries genuinely use technical terms. Keep them when the customer understands and expects them.
Replace internal marketing language when it hides a simpler service name.
Use sales calls, search queries and customer emails to collect the language buyers already use.
Test individual service pages too
A homepage can pass the test while a service page fails.
For each major service page, ask:
- Which service is this?
- What problem does it solve?
- What is included?
- Who is it for?
- What should I do next?
A visitor may arrive directly from Google, Maps, LinkedIn or an AI answer without seeing the homepage first.
Every important landing page needs enough context to stand on its own.
Use hierarchy, not more text
Clarity problems are not always copy problems.
The right words can disappear when:
- heading is smaller than decorative text;
- CTA has low contrast;
- animation delays the message;
- navigation overlaps the hero;
- desktop columns collapse badly on mobile;
- too many badges compete for attention.
Fix visual priority before adding another paragraph.
Score the first screen
Use a simple 0–2 scale:
| Item | 0 | 1 | 2 |
|---|---|---|---|
| Service | unclear | partly clear | immediately clear |
| Audience | unclear | implied | clear where relevant |
| Location | wrong/missing | partly clear | clear where relevant |
| Primary action | unclear | visible but vague | obvious and specific |
| Proof | none | generic | relevant evidence |
A low score tells you what to rewrite or reorganise.
Do not turn the total into a universal conversion benchmark. Use it to compare versions of your own page.
Retest after the rewrite
Show the new version to someone else.
If the same confusion remains, the team may be too close to the language.
Keep the version that produces clearer answers, then measure real website behaviour:
- service-page engagement;
- CTA clicks;
- form completions;
- qualified enquiries;
- sales conversations.
A page can be clear and still have a weak offer. The test isolates communication from the rest of the sales problem.
IDJoy uses clarity testing before visual polish when planning a website redesign, because animation cannot rescue a service the visitor cannot identify.
