SortSite is an automated tool that scans your website for device compatibility and accessibility. Bonus: It also checks for search engine optimization (SEO), broken links, and secure connections.

SortSite is a tool that stood out to us and gave us good results. To date we have scanned multiple applications at DOH and the results have been informative and helpful in assessing the accessibility and assisting us with what to fix.

This simple test works very similarly to the desktop browser test, but gives much more useful data than just a screenshot. The "SortSite" test checks accessibility, broken links, browser code compatibility, search engine optimization and other usability issues...
