What is website accessibility?

Web accessibility, or eAccessibility, is an active effort to ensure that there are no barriers preventing people with physical disabilities, situational disabilities, and socio-economic restrictions on bandwidth and speed from interfacing with or accessing websites.

Many of us take these things for granted because we don’t perceive the same hurdles as some people do when reading and navigating websites, filling out online forms, and differentiating colours in the case of colorblindness.

With so much of our work, social life, and family life happening online, website accessibility is paramount to an excellent user experience.

Here are twelve common accessibility barriers, all of which can be adjusted with simple accessibility software. 

Our tool makes the adjustments necessary to accommodate the individual user. In one action, the site becomes accessible to that user according to one of the twelve most common accessibility barriers listed below.

12 Common Accessibility Barriers

Want to know where to start on your journey toward better web accessibility? We’ve outlined the twelve most common accessibility barriers that we use to measure a site’s fitness during an audit.

Cognitive barriers

A person’s ability to concentrate on complex language due to conditions like dyspraxia, dyslexia, dyscalculia, and dysgraphia could make comprehending legal, academic, and technical materials challenging.


Someone with colorblindness could find it hard to navigate certain websites and apps due to the colours they use. For example, low colour contrast between text and background makes it harder to differentiate between them.

Insufficient alternative text

Screen readers employ alt text to describe an image to a person with a vision impairment. Including correct and clear alt text makes images more accessible to people with disabilities.

Keyboard accessibility

Keyboard Accessibility. Users who experience mobility impairments or motor disabilities can find it challenging to use a mouse similarly. Keyboard accessibility helps correct this by enabling navigating sites without a mouse.

Motor impairment

Motor impairment affects people with movement disabilities, resulting from either old age or specific conditions. A mobility or dexterity impairment user may have difficulty using a mouse to click on a small checkbox on a web page.

Small text

Text that’s too tiny to read can be a significant obstacle for people with visual impairments. The solution is that they should be able to magnify it easily.

Hearing impairment

A person with a hearing impairment would need alternative text on videos that include information and instructions given orally.


Attitudinal barriers are behaviours, perceptions, and assumptions that discriminate against persons with disabilities.

Inaccessible documents

Inaccessible documents are a common issue for websites because they prevent equal access to information.

Information or communications

Information or communication barriers occur when sensory disabilities, such as hearing, seeing, or learning disabilities, have not been considered.


It’s wonderful that audio and video bring concepts to life, but they are unavailable to those with hearing or visual impairments when video captions in various languages are missing.

Neurological disorder

Computer monitors emit bright lights, a common trigger for people with migraines. Extensive staring and flickering images cause eyestrain, and bright or flashing lights may trigger a seizure or migraine.

When websites aren’t adjustable to make them more accessible, all the people who experience the barriers mentioned above will have a poorer experience on your site and may not choose to return. They may even select your competition instead. This may have happened already without you knowing.

Why Website Accessibility Matters

Website accessibility is important for inclusivity in work, using government services to obtain a driver’s license or passport, and even going shopping or paying taxes.

Even for those of us who don’t have the type of disability that prevents us from fully experiencing a website, social media program, or app like WhatsApp, we may find that we develop such conditions in the future. 

Someone can also experience temporary disability if they have an eye or ear injury, for instance. Or a person suffering from a migraine that inhibits their comfort in front of a computer screen.

But what if your job requires you to work in front of a computer? If you live with migraine and work on a computer, managing migraine can get tricky.
