This may be your toughest determination of all. Compare the subjects and suggestions you're reading with the types of products and services that may be advertised within, or along side, content, or somewhere else on the site. Let's say that you're skimming an article about new technological advances in the development of hearing aides. Next to this text fades in an ad promoting Hawaiian beach vacations. If the other checklist items check out, it doesn't appear that this article is being affected one way or the other by this ad.
More health information is better.
