A broad keyword is a search term that is very general and covers a wide range of topics. It is typically used to cast a wide net and attract a large audience, but it may not be as targeted as a more specific, narrow keyword.
For example, "shoes" is a broad keyword, while "women's running shoes" is a narrow keyword. The broad keyword will attract a large audience, but the narrow keyword will attract a more targeted audience that is specifically looking for women's running shoes.
Using broad keywords in your search engine optimization (SEO) and advertising strategies can help you reach a large audience, but using narrow keywords can help you attract a more targeted and engaged audience
