Unusable Forms
Problem: Forms are often not labelled correctly or don’t support screen readers. Fields may lack error messages or instructions.

Impact:

• Users with visual impairments cannot complete contact or registration forms.
• Keyboard-only users can’t tab through fields in the right order.
• High drop-off rates during form submissions.
• Lost leads, particularly if the form is the primary call-to-action (e.g., demo requests, email sign-ups).

Poor Readability
Problem: Dense blocks of text, jargon-heavy language, and lack of headings or structure make content difficult to process.

Impact:

• Users with dyslexia, ADHD, cognitive impairments, or low literacy levels are excluded.
• In biotech or healthcare, complex information is made even harder to understand.
• Visitors abandon pages without fully engaging with your message or offering.

Inadequate Colour Contrast
Problem: Text or buttons don’t stand out against the background due to low colour contrast.

Impact:
Users with visual impairments or colour blindness struggle to read or interact.

Key calls-to-action (CTAs) become invisible or difficult to use.

Brand credibility is undermined when users can't navigate or trust the interface.

Missing Alternative Text (Alt Text)
Problem: Images and graphics lack meaningful descriptions.

Impact:

• Screen reader users are unable to understand context conveyed through visuals.
• Search engines can’t index image content, reducing SEO performance.
• In biotech, data visuals like charts or infographics lose their value.

Keyboard Navigation Failures
Problem: Users cannot navigate via keyboard alone—focus indicators are missing, menus are inaccessible, or modal pop-ups trap users.

Impact:

• Users with mobility challenges are excluded entirely.
• Regulatory non-compliance risks increase.
• Frustrated users quickly leave the site.

Non-Responsive or Touch-Unfriendly Elements
Problem: Buttons and links are too small, too close together, or not touch-friendly.

Impact:

• Users on mobile devices or with motor impairments struggle to interact.
• Conversion tasks (e.g. booking, purchasing, submitting enquiries) become barriers.
• High exit rates from mobile users—potentially 50% or more of traffic.

No Clear Page Structure
Problem: Pages lack semantic HTML (proper headings, landmarks, and regions).

Impact:

• Screen reader users cannot scan or understand page layout.
• Key messages are lost due to visual or structural confusion
• Lower engagement with content and weaker SEO performance.
