When accessible features are built into web pages, websites are more convenient and more available to everyone – including users with disabilities. Web designers can follow techniques developed by private and government organizations to make even complex web pages usable by everyone including people with disabilities. For most websites, implementing accessibility features is not difficult and will seldom change the layout or appearance of web pages. These techniques also make web pages more usable both by people using older computers and by people using the latest technologies (such as personal digital assistants, handheld computers, or web-enabled cellular phones).

Error prevention on important forms (3.3.4): For pages that create legal commitments or financial transactions or any other important data submissions, one of the following is true: 1) submissions are reversible, 2) the user has an opportunity to correct errors, and 3) confirmation is available that allows an opportunity to review and correct before submission.
How much their services cost. One of the most important things to determine is how much you’re willing to spend on a website, and then take note of how much each agency charges. The sentiment holds true that you typically get what you pay for — if a web design agency is charging dirt cheap for a design, you probably won’t be happy with the results. There is definitely room to have a budget, but keep in mind what you’ll generally need to pay for a high-quality website.

Ultimately, the DoJ’s letter has placed the burden back on Congress to legislate regarding ADA website accessibility.  However, it is unlikely that it will take any action any time soon.  While the DOJ’s letter is helpful for businesses, it will not stop these ADA website accessibility lawsuits.  Therefore, businesses should take proactive steps toward making their websites accessible.  Employers must also remember that their failure to make online job applications accessible to blind or disabled job applicants may subject them to liability under Title I of the ADA, which prohibits discrimination in hiring decisions, and which carries with it additional remedies such as compensatory damages (to pay a plaintiff for out-of-pocket expenses caused by the discrimination and compensate him/her for any emotional harm suffered), and punitive damages.
Websites must also be completely in conformance, and cannot achieve conformance if part of a website is excluded.  Further, all the information presented by, and the functionality of, web content technologies (such as HTML, CSS, and JavaScript) must be supported by accessibility web content technologies.  For more information on the five requirements for WCAG 2.0 conformance, see W3C’s WCAG’s Success Criteria, which are designed to allow online content to be tested to determine whether it satisfies the requisite criteria for a conformance level.  Testing should involve a combination of automated testing and human evaluation.
