Clickbait is content that uses manipulative copy to convince users to click on it. Clickbait tends to rely on exaggeration and withholding information to push people into clicking. For example, an article with the headline “Doctors HATE him for using this one WEIRD TRICK…” but just says you should work out regularly is considered clickbait because it compels people click it to learn more while being thin on actual content. Social networks like Facebook consider clickbait spammy and lower its reach accordingly.
something (such as a headline) designed to get attention and make readers want to click on a link. Often it is misrepresenting what the content will entail and the content will under-deliver.
