==Website accessibility audits==
A growing number of organizations, companies and consultants offer ''website accessibility audits''. These audits, a type of [[system testing]], identify accessibility problems that exist within a website, and provide advice and guidance on the steps that need to be taken to correct these problems.

A range of methods are used to audit websites for [[accessibility]]:
* Automated tools such as the [https://www.checkmeister.com/evaluation Check Meister] website evaluation tool are available which can identify some of the problems that are present. Depending on the tool the result may vary widely making it difficult to compare test results.<ref>{{cite web|last=Krantz|first=Peter|title=Pitfalls of Web Accessibility Evaluation Tools|date=23 April 2009 |url=http://www.standards-schmandards.com/2009/pitfalls-of-web-accessibility-evaluation-tools/|publisher=Standards-schmandards.com|access-date=23 December 2012|archive-date=19 December 2012|archive-url=https://web.archive.org/web/20121219084918/http://www.standards-schmandards.com/2009/pitfalls-of-web-accessibility-evaluation-tools/|url-status=live}}</ref>
* Expert technical reviewers, knowledgeable in web design technologies and accessibility, can review a representative selection of pages and provide detailed feedback and advice based on their findings.
* User testing, usually overseen by technical experts, involves setting tasks for ordinary users to carry out on the website, and reviewing the problems these users encounter as they try to carry out the tasks.

Each of these methods has its strengths and weaknesses:
* Automated tools can process many pages in a relatively short length of time, but can only identify a limited portion of the accessibility problems that might be present in the website.
* Technical expert review will identify many of the problems that exist, but the process is time-consuming, and many websites are too large to make it possible for a person to review every page.
* User testing combines elements of usability and accessibility testing, and is valuable for identifying problems that might otherwise be overlooked, but needs to be used knowledgeably to avoid the risk of basing design decisions on one user's preferences.

Ideally, a combination of methods should be used to assess the accessibility of a website.
