Automatic or manual web accessibility validation?

Web accessibility validation is key when it comes to guaranteeing access to websites for everyone. And this is even truer today, where this requirement is driven by regulations such as Royal Decree 1112/2018.

But what type of validation should be used when working with web accessibility? Continue reading to find out.

There are a number of tools that allow you to automatically evaluate web accessibility, with the aim being to quickly detect any errors in the website’s code. However, the very nature of this kind of tool means that it is difficult to fully check whether the web page is really accessible or not. This is because many issues or coding errors are not processed automatically and need to be detected manually.

The only way to ensure an exhaustive appraisal when performing a complete evaluation and validation of web accessibility and to guarantee that your website conforms to accessibility regulations is to have a team of experts in web accessibility perform both – combining automatic and manual evaluation.

These professionals are really the only ones who are able to interpret the accessibility errors that are automatically detected; they will also be able to manually identify any errors that might have gone undetected by automatic analysis. Furthermore, they are the ones who can best advise and help you resolve all detected errors in order to comply with accessibility regulations quickly and easily.

Automatic evaluation tools are our best allies when they are employed in combination with other actions, resulting in true web accessibility. Automatic evaluation tools considerably reduce the time and effort needed once in-depth evaluation has been performed.

This allows us to better detect and minimize accessibility barriers that may exist on a web page, which in turn has a direct impact on the general quality of the site.

A complement to accessibility evaluation and not a complete analysis

It is important to understand that automatic validations are not infallible. On the contrary, there are certain limitations to what they can do when running the required analyses.

Moreover, they can falsely detect certain errors which then need to be analysed, corrected, or discarded by an expert. That is why we recommend that users understand how these automatic accessibility evaluation tools work, as well as their advantages and disadvantages.

In this sense, it is essential to rely on the experience of an expert who can analyse how such tools behave vis-à-vis any accessibility problems that arise.

This is how we are able to select the conformity criteria that must be considered when evaluating a website correctly.

Differences between manual and automatic accessibility evaluation

To help you understand the advantages and disadvantages of manual and automatic accessibility validations, we have prepared a list of characteristics to take into account when evaluating web accessibility.

Manual validation

Automatic validation

Once you understand the characteristics of each type of website accessibility validation tool, it is important to understand the relevance of implementing both types, each complementing the other.

It is important to understand that if you combine these two validation methods, you will obtain more detailed, richer information, allowing experts to propose effective website accessibility solutions.

Which criteria should be reviewed manually, and which can be reviewed automatically?

As a general rule, we could say that only 20% of the WCAG 2.1 Level AA criteria can be reliably evaluated automatically. However, there are some criteria that can be met using semi-automated procedures. This facilitates evaluation and notably reduces the effort required in a manual review.
