Here at Cludo, not only is accessibility important to us, but to our customers, and our customers' customers. We've ensured that our overlay and inline templates are created to be compliant with the WCAG 2.0 (Web Content Association Guidelines) and US Section 508 guidelines. If you decide to use Cludo's professional services to build a custom search, know that we have accessibility testing included in the implementation.
Note: If you have built your site search using the API, we cannot guarantee it is compliant. Please review this with your developers.
If you have any concerns about accessibility, do not hesitate to contact our support.
