Accessibility checks are based on the WCAG Success Criterion. The default set of checks are tests that can be programmatically determined not to meet a WCAG Success Criterion.

Accessibility checks will impact the Accessibility Score and the Overall Site Score.

These checks are NOT tied to a specific WCAG Success Criterion. These are established best practices for website development. Some of the tests may be related to WCAG-ARIA recommendations but these are still not required per the WCAG Success Criterion. In short, these rules do not pose a barrier to a user accessing website content but could potentially improve the user experience.

Best Practice checks will impact the Best Practice Score but NOT the Overall Site Score.

Links that do not reply with a 200 OK response will be reported as Broken Links within DubBot. False positives may be reported because a web server actively identifies and blocks bot traffic. Users can ignore reported broken links that are false positives by using the Ignore options presented throughout DubBot. Administrators may also update an account or site's settings to ignore broken links based on their response type or using a regular expression to more finely target specific link domains or structures.

More information on customizing the Broken Link checks can be found here:

Exclude broken links reported by reason (or response code)

Broken Link checks will impact the Broken Link Score and the Overall Site Score.

Administrators can select which Dictionary language is used for the account and specific sites. Users can add words to their dictionary by using the Ignore word or Add to dictionary option presented throughout DubBot. Administrators may also bulk add words to their dictionary using a CSV.

Spelling checks will impact the Spelling Score and the Overall Site Score.

Search Engine Optimization (SEO) checks provide basic information on whether a page uses the basic best practices for SEO. This includes pages with a title and description. Users can ignore reported SEO checks by using the Ignore options presented throughout DubBot.

SEO checks will impact the SEO Score and the Overall Site Score.

Web Governance checks will report by default any Flagged Words and any Policies that have been added to the DubBot system. Policies may be added during the account configuration or later using the Policy Library or by Creating a Custom Policy .

Policies can be added or requested by an account or site administrator for many reasons. The most common reasons for Policy additions are to find content that requires verbiage change, enforcement of organizational best practices, and Accessibility checks that could prompt the need for manual review. Policies added are assigned to the Web Governance category by default but can be ruled into any other check category through its Advanced settings panel.

Web Governance checks will impact the Web Governance Score and the Overall Site Score.
