Explore usability and accessibility assessment

For all your customers

The more people can use your website, the more potential customers you can reach.

Some people use only a keyboard, enlarge text or use a screen reader. We build with them in mind so that more customers can contact you.

  • Without relying on a mouse. Menus and forms can be reached using only a keyboard, with a visible indication of your position.
  • Well-organised pages. Clear headings and sections help everyone understand a page.
  • Images with descriptions. People who cannot see an image can understand what it shows.
  • Easy-to-read text. Text stands out from the background and remains readable when enlarged.
  • Screen reader support. Identified buttons and fields help people who listen to the website rather than read it.
  • Mobile or desktop. The website adapts to each visitor's screen.

An automated score is not a certification. A result of 10/10 does not certify full compliance with WCAG 2.1 or 2.2 Level AA. The five flagged practices require manual verification; automated testing must be complemented by human assessment and use with assistive technologies. Read the W3C's explanation of automated testing limitations.

Working with the public sector? Accessibility is a legal requirement.

If your organisation is covered, its website must meet the applicable accessibility requirements and publish a statement. We help clarify what applies to your project.

View the legal framework and standards

In Portugal, websites and mobile applications of public sector bodies covered by Decree-Law No. 83/2018 must meet the applicable accessibility requirements and publish an accessibility statement. A technical assessment should identify the version of European standard EN 301 549 and the requirements applicable to the project.

EN 301 549: the European reference for digital accessibility

EN 301 549 sets accessibility requirements for information and communication technology products and services. Its scope goes beyond websites to digital documents, software and other components, depending on the product or service.

For a web project, the assessment should consider the WCAG criteria included in the applicable version of the standard and other relevant requirements. This includes checking content, navigation, forms, published documents and compatibility with assistive technologies.

The AccessMonitor and WAVE results on this page help identify barriers but do not, on their own, demonstrate full compliance with EN 301 549. A compliance conclusion requires assessment of the applicable requirements and documented evidence.

How do EN 301 549 and WCAG relate?

For the Web, version V3.2.1 incorporates WCAG 2.1 Level A and AA criteria, plus additional requirements. Version V4.1.1, published in September 2026, incorporates WCAG 2.2. A new edition does not automatically replace the version referenced in legislation or a contract: each assessment should state the version and framework it uses.

Accessibility on mobile too

Accessibility requirements also apply when a website is used on a mobile device. Content should adapt to small screens and magnification without losing information or functionality, subject to the exceptions in the standards. Screen orientation should not be restricted unnecessarily, and controls should not depend on complex gestures. Contrast, field identification and screen reader compatibility remain essential.

Read the WCAG 2.1 requirements

Usability helps people understand and complete tasks. Accessibility aims to ensure that people with disabilities can also complete those tasks, including people using a keyboard or assistive technology. Assessment should combine automated checks and manual testing.

Speed

Less waiting. More customers.

Lightweight pages, including on mobile.

  1. Lightweight imagesGood quality, smaller files.
  2. The essentials firstThe rest loads as you scroll down.
  3. Simple codeLess overhead, faster responses.

Approximately 300 KB transferred

The reported volume for the homepage's initial load. It represents the data transferred during that visit, rather than the total size of every available file.

Approximately 2 MB across 41 resources

The total size of the resources identified in the inventory, including image variants. The browser selects the versions appropriate for the screen; it does not download all of them at once.

92,220 bytes in the HTTP response

Around 90 KiB (92.2 KB), according to WebSitePulse. Website Test downloads the HTML; this is not the size of the full page with images, fonts and styles.

474 ms response time

Time recorded by WebSitePulse's Website Test, run from New York. It is not a measurement of the complete page load, nor a guarantee of the same result from another location or connection.

First Byte: 95 ms

The value shown in WebSitePulse's First Byte field, using that tool's methodology. It should not be confused with the total request time or the time to load the page in a browser.

How to interpret these figures
HTML size
The size of the document containing the structure and text. By itself, it does not include all referenced resources.
Total resources
The sum of the files in the inventory, which may include alternative versions of the same content.
Data transferred
What actually crosses the network during a visit. It depends on compression, caching, the screen and when images are requested.
Page load time
Includes browser processing and resource requests. It cannot be deduced from HTML size or HTTP response time alone.

Security

Fewer components. Fewer risks.

A simple structure with the right precautions.

  1. SimplifyFewer exposed components where the project allows it.
  2. ProtectHTTPS, controlled access and backups.
  3. MaintainHosting and forms also need attention.

Lower risk does not mean zero risk.

How do we choose and protect the structure?

Where a project allows it, we build the website with static HTML and fewer exposed components. The solution depends on your business needs.

What may be unnecessary

  • A database to generate every page.
  • An exposed administration login system to serve the public website.
  • Presentation plugins requiring frequent updates.
  • Dynamic server processing for every visit.

Ongoing precautions are still necessary

Reducing the attack surface does not eliminate all risks. Hosting, the domain, HTTPS, publishing access and backups still need attention.

Forms, stores and restricted areas add their own components. A contact form, for example, uses a service that also needs maintenance and protection. We explain what your project requires.

We choose the architecture to suit the business. Professional HTML websites are an option for suitable projects; an online store or an integration may need a different solution.

Predictable costs

Less maintenance. More simplicity.

Fewer components to update and fix.

  • Keep it workingCheck security, links and forms.
  • Keep it currentReview services, prices and contact details.
What does maintenance involve?
  • Fewer dependencies and technical updates.
  • Efficient hosting for static files.
  • Fewer interventions caused by incompatible components.
  • More predictable maintenance work.

Technical maintenance

Review security, links, forms, compatibility and hosting. A static website still needs these checks, even without the maintenance of a CMS and its plugins.

Content updates

Changing services, contact details, prices, images or articles is separate work. Technical simplicity does not remove the need to keep information current and useful.

The AccessMonitor link was supplied for viewing the report. The service may show a more recent assessment. The historical figures are those reported in the record for that date; they are neither certification nor a permanent guarantee.

Measurement conditions and limitations

The device, connection, location, cache, page version and tool affect the results. The WebSitePulse screenshot shows separate fields for DNS (59 ms), connection (80 ms), redirects (0 ms), First Byte (95 ms) and Last Byte (241 ms), as well as the total response time of 474 ms. These fields follow the tool's methodology and should not be treated as cumulative times from the start of the request. The screenshot does not identify a separate TLS component.

Accessibility scores should be accompanied by manual testing. A good one-off measurement helps assess the work but does not guarantee the same result on every visit.

PageSpeed Insights results are presented by device, using the figures and screenshot shared on 10 October 2026. They are laboratory tests without real user data.
