Websites should always present good original content which respects copyright of authors and creators as well as site visitors and their privacy. By law, every website is required to be transparent about data handling (via a privacy policy) and state clearly which settings are in place as well as asking for explicit consent to set cookies.
When writing your content, always keep your readers in mind ~ these are the people you write for, your target group and it is up to you to make your text clear and easy to understand. Your subject might involve a certain terminology, or subject-specific jargon [1] or abbreviations, for example. Consider whether certain phrases would benefit from explanations, and offer additional information as fitting context.
