It’s important to note that webpage complexity is increasing. For the top million web pages, the number of home page elements has increased by 50% in the last five years and nearly 12% in the last year. Further, the frequency of accessibility errors isn’t dropping. A staggering 95.9% of the top million homepages have WCAG 2 errors, a decrease of only 1.9% over the last five years.

Many areas of your website can adversely affect accessibility. These include the code (code structure, missing special tags, improperly working tabs), the content (missing metadata, images without alt text or not conforming to guidelines), or the design itself (poor color contrast, inconsistent font sizes, badly contrasting font colors, text covering images, missing hierarchies or illogical ordering of information). These can be improved by addressing some or all of the following:

• Follow Web Content Accessibility Guidelines — strive for AAA WCAG compliance.
• WebAIM is also a good resource for improving website accessibility.
• Consult accessibility experts or users. Their familiarity can help you catch things other users might miss.
• Good partners can also help ensure you design and implement with accessibility in mind. Address and fix errors — and catch accessibility warnings before they become errors.
• Ensure metadata fields are as complete and accurate as possible.
• Coordinate accessibility efforts among your editors, dev, and design teams.
• Accessibility errors can occur in both the code and the content.
• Cultivate a culture where accessibility is part of the workflow, not an afterthought.
