# Accessibility checker and resources

## Browser extensions

There are many browser extensions you can install to identify issues related to WCAG 2.1 AA (and beyond) in your store.\
\
We recommend the free extension **Silktide**. This tool includes a scan/checker to highlight issues directly and visually. It also offers a contrast checker, a voiceover function, a chart to display the tab order, and much more.

### Online Accessibility Checker-Tools

There are numerous online accessibility checker tools that can scan your website and identify problem areas.\
\
A widely used tool for testing your store's accessibility is **Google PageSpeed ​​Insights**. It checks your store for common WCAG standards and provides you with concrete recommendations on what to do to improve your store's accessibility. PageSpeed ​​Insights assigns a score to the tested page. If the result is in the green zone (over 80 points), your store has passed the test.

It's always a good idea to rely on multiple sources. Therefore, using another tool to complement existing measures can't hurt.

AccessibilityChecker.org is another one we recommend. It clearly shows, structured in tabs, which measures still need to be taken to ensure your store is legally compliant.
