Web Content Accessibility

Website SEO content accessibility means that websites, tools, and technologies are designed and developed so that people with disabilities can use them. By making web content accessible, we can help ensure that everyone has equal access to the information and services they need.

Making web content accessible is not only important for people with disabilities. It also benefits older adults, people with limited technology skills, and people using mobile devices. That is why, Showeblogin suggest each and every website owner and web developers to make site accessible to everyone.

You can also find accessibility tools and plugins for many popular web development platforms including WordPress website.

  1. Check your page titles and meta descriptions. Make sure they are clear, concise, and accurately describe the content of your page. Keyword research and use only relevant keywords, but avoid keyword stuffing.
  2. Check your headings. Use heading tags (H1, H2, H3, etc.) to structure your content and make it easier for search engines to understand.
  3. Check your images. Add alternative text (alt text) to all of your images. Alt text is a brief description of the image that is read by screen readers. Read Showeblogin image SEO guide.

Website accessibility check tools are used to identify and evaluate accessibility issues on websites. These tools can help to ensure that websites are accessible to people with disabilities, such as those who are blind, low vision, deaf, or hard of hearing, or have other mobility or cognitive impairments.

Web Content Accessibility Guidelines (WCAG)

The Web Content Accessibility Guidelines (WCAG) are the international standard for web accessibility. They provide a set of guidelines for making web content more accessible to people with disabilities. Here we have summarized the WCAG for the beginner:


Information and user interface components must be presentable to users in ways they can perceive.

Text Alternatives: Text alternatives for non-text content are descriptions of what the non-text content is and what it conveys. It can be changed into other forms people need, such as large print, braille, speech, symbols or simpler language.

Here are some examples of how to provide text alternatives for different types of non-text content:

  • Images: Include descriptive alt text for all images.
  • Videos: Provide captions and transcripts for all videos.
  • Audio recordings: Provide transcripts for all audio recordings, such as podcasts and interviews.
  • Charts and graphs: Provide text descriptions of charts and graphs.
  • Interactive content: Provide text alternatives for all interactive content, such as forms and quizzes. For example, you could provide a text alternative for a submit button that says “Submit this form.”

Time-based Media: Alternatives for time-based media are text-based (but not necessarily text-only) documents that present the same information as the time-based media. They are important for making content accessible to people who are deaf, blind, or have other disabilities that make it difficult for them to consume time-based media.

Adaptable: Create content that can be presented in different ways (for example simpler layout) without losing information or structure. Here are some tips to do that:

  • Start with a clear outline.
  • Use headings and subheadings to break up your text.
  • Use clear and concise language.
  • Use examples and illustrations to support your points.
  • Use visuals, such as infographics, charts, and images, to break up your text and make your content more visually appealing.

Distinguishable: Make it easier for users to see and hear content including separating foreground from background.

Use sufficient color contrast between text and background. The Web Content Accessibility Guidelines (WCAG) recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (18px or 14px bold).

Make sure that audio is loud enough to hear, but not so loud that it is jarring. Provide captions and transcripts for audio content.


User interface components and navigation must be operable.

Keyboard Accessible: Make all functionality available from a keyboard. Keyboard focus is a visual indicator that shows which element on a page or screen has the keyboard focus. Users can use the Tab key to move the keyboard focus between different elements.

Use keyboard shortcuts to provide shortcuts to common actions. Keyboard-accessible controls are controls that can be operated using the keyboard. For example, input fields, buttons, and menus should all be keyboard-accessible.

If you are unable to perform any actions using only the keyboard, then your website or app is not keyboard-accessible and you need to make changes.

Enough Time: Provide users enough time to read and use content. There are a number of ways to provide users enough time to read and use content. Here are a few tips:

  • Avoid time limits
  • Provide pause, stop, and hide controls
  • Provide adjustable time limits
  • Provide clear and concise instructions
  • Test your content with users.

Seizures and Physical Reactions: Do not design content in a way that is known to cause seizures or physical reactions.

Navigable: Provide ways to help users navigate, find content, and determine where they are.

Input Modalities: Make it easier for users to operate functionality through various inputs beyond keyboard.


Information and the operation of the user interface must be understandable.

Readable: Make text content readable and understandable.

Predictable: Make Web pages appear and operate in predictable ways.

Input Assistance: Help users avoid and correct mistakes.


Content must be robust enough that it can be interpreted by a wide variety of user agents, including assistive technologies. Some examples of assistive technologies include screen readers, which read text aloud to blind users; speech recognition software, which allows users to control their computers with their voice; and braille displays, which allow blind users to read and write braille.

To maximize compatibility with current and future user agents, including assistive technologies, you should:-

  • Use valid and well-formed markup.
  • Provide transcripts for all audio and video content.
  • Use standard HTML controls and elements whenever possible.
  • Provide descriptive labels for all form controls and other interactive elements.
  • Use appropriate ARIA roles and states to describe the purpose and behavior of custom elements.
  • Provide captions for all video content.
  • Use CSS to style your content instead of JavaScript.
  • Avoid using images to convey important information.

This is known as the Robustness Principle of the Web Content Accessibility Guidelines (WCAG) 2.1 and 2.2.
