As I mentioned above, under each WCAG 2.1 principle is a list of guidelines, and under each guideline are compliance standards, with techniques and failure examples at each level. Some guidelines include only Level A items; others include items for multiple levels of conformance, building from A to AAA. At each stage, you can easily see what more you would need to do to reach Level AA or AAA. In this way, many websites include elements at multiple levels of accessibility.
Today, however, the landscape is completely different at the Dept. of Justice. In 2001, Target was sued by the National Federation of the Blind over its web site. Target said the ADA didn’t cover web sites but was told by a judge that they were liable because they were connected to a brick and mortar business. If a company isn’t tied to a brick and mortar business, however, the courts are still split on that issue regarding ADA coverage.

These statistics are especially important when you consider the potential spending power of people with disabilities. Unfortunately, if the website isn’t accessible, then it is excluding more than 60 million Americans14. Additionally, 71 percent of customers14 with disabilities will instantly leave the site if it does not meet their accessibility needs. Another 80 percent of customers14 with disabilities have stated that they will spend more on a website that has improved accessibility features. Fortunately, if you follow Web Content Accessibility Guidelines (WCAG)7, then you can appeal to millions of individuals who want to enjoy the same online experiences as their friends, family, and neighbors. Giving them the chance is not only right, but it is also in accordance with ADA regulations.
Higher search engine rankings is another potential benefit of voluntary compliance with the ADA. During your migration, an ADA specialist will audit it to detect and address usability challenges. These difficulties include the inability for search engine spiders to index your site easily. When you address such issues, your site will rank highly in search engines.
Two agencies within the U.S. Department of Labor enforce parts of the ADA. The Office of Federal Contract Compliance Programs (OFCCP) has coordinating authority under the employment-related provisions of the ADA. The Civil Rights Center (CRC) is responsible for enforcing Title II of the ADA as it applies to the labor- and workforce-related practices of state and local governments and other public entities. Visit the Laws & Regulations subtopic for specific information on these provisions.
When choosing an aid or service, title II entities are required to give primary consideration to the choice of aid or service requested by the person who has a communication disability. The state or local government must honor the person’s choice, unless it can demonstrate that another equally effective means of communication is available, or that the use of the means chosen would result in a fundamental alteration or in an undue burden (see limitations below). If the choice expressed by the person with a disability would result in an undue burden or a fundamental alteration, the public entity still has an obligation to provide an alternative aid or service that provides effective communication if one is available.
Reha asked Vu if companies are obligated to comply? Vu said that unlike the physical access world, where any new building has to be compliant no matter what, there’s no such thing in the web world. The Justice Dept. hasn’t said that that’s the default, but they have said that the current regulatory regime requires it anyway. Equal access has been around since 1990.
Web accessibility addresses the needs of every website visitor to achieve an optimal level of usability and ADA compliance. Many people browsing the web have a permanent disability (visual, mobility or neurological impairment), or a temporary impairment such as a broken arm, broken or lost eyeglasses, and so on. Many baby boomers have aging-related issues that make using the web more challenging, and they’re not alone–about 20% of the U.S. population has an identified disability.
...the full and equal enjoyment of the goods, services, facilities, or accommodations of any place of "public accommodation" by any person who owns, leases, or operates a place of public accommodation. Public accommodations include most places of lodging (such as inns and hotels), recreation, transportation, education, and dining, along with stores, care providers, and places of public displays.
