Why WCAG basics belong in every launch checklist
A WCAG accessibility checker is a starting point for making sure a public page can be used by more people, more devices and more assistive technologies. Automated checks cannot certify full WCAG conformance, but they can catch the launch mistakes that make a site harder to navigate: missing alt text, absent language declarations, poor viewport setup and mobile controls that are awkward to use.
Good accessibility is practical. Images that carry meaning need useful alt text. Decorative images should not create noise for screen readers. The page language should be declared so assistive technology can choose the right pronunciation. Forms, links and buttons should make sense without relying only on visual layout.
Teams often leave accessibility until the end, then discover that simple template issues repeat across every page. Running a lightweight checker early helps you fix the pattern once, reduce compliance anxiety and make the full manual WCAG review more focused.
Frequently asked.
- Can this WCAG accessibility checker certify compliance?
- No automated checker can certify full WCAG compliance. This tool catches public-page basics and helps you decide what needs a deeper manual review.
- Which WCAG issues are easiest to catch automatically?
- Missing alt text, missing language tags, viewport problems, unlabeled controls and obvious mobile usability issues are good automated first-pass checks.
- Why check accessibility before launch?
- Template-level accessibility issues multiply across a site. Finding them before launch is cheaper than retrofitting every page after users, customers or regulators find the same problem.
- What should I do after the free check?
- Fix the deterministic issues first, then run a manual keyboard, screen reader and contrast review for important journeys such as pricing, signup and checkout.
