PDF testing

Sitemorse performs twenty eight checks on PDF documents as part of our website benchmarking to ensure users do not experience problems such as broken links, or failing email addresses - we are also the first to test the accessibility compliance of PDF's.

26.7% of checked PDF's passed accessibility tests
