Wikipedia:Follow highlighting conventions

Follow our established conventions for highlighting and linking.

An article should start with an introductory sentence that contains the word or phrase that the article is about, which should be boldfaced. This makes it easier for the casual reader to identify the topic, especially when the text is copied to a different context.

Don't highlight every instance of title item in text body. The reader knows what article he or she is reading from both the title at the top of the page and the browser's title bar. Making every instance highlight with bold typing style is unnecessary.

Also, don't make the title term a link--an article should not link to itself. When you do create links, link only one or a few instances of the same term, don't link all instances of it.
