Hypertension websites are widely and easily accessible. This study aims to assess the understandability and actionability of hypertension websites. Eight websites that met the inclusion criteria were included. Eight experts were appointed to evaluate the websites using PEMAT instrument. The overall mean scores for understandability and actionability were 76.08% and 52.83% respectively. One website did not meet the criteria for understandability (score of ≥70%), while almost all materials failed to meet the criteria for actionability (score of ≤70%). In conclusion, this study provides evidence that many of the available hypertension websites can be easily understood but are less actionable.
