Abstract Objectives To analyse the quality of information included in websites aimed at the public on COVID-19. Methods Yahoo!, Google and Bing search engines were browsed using selected keywords on COVID-19. The first 100 websites from each search engine for each keyword were evaluated. Validated tools were used to assess readability [Flesch Reading Ease Score (FRES)], usability and reliability (LIDA tool) and quality (DISCERN instrument). Non-parametric tests were used for statistical analyses. Results Eighty-four eligible sites were analysed. The median FRES score was 54.2 (range:23.2-73.5). The median LIDA usability and reliability scores were 46 (range:18-54) and 37(range:14-51), respectively. A low (<50%) overall LIDA score was recorded for 30.9% (n = 26) of the websites. The median DISCERN score was 49.5 (range: 21-77). The DISCERN score of ≤50% was found in 45 (53.6%) websites. The DISCERN score was significantly associated with LIDA usability and reliability scores (p < 0.001) and the FRES score (p = 0.024). Conclusion The majority of websites on COVID-19 for the public had moderate to low scores with regards to readability, usability, reliability and quality. Practice Implications Prompt strategies should be implemented to standardize online health information on COVID-19 during this pandemic to ensure the general public has access to good quality reliable information.
