Broad Keywords are typically short, general terms or phrases that attract significant search traffic, but are often associated with high competition and low conversion rates. For example, terms like "shoes" or "mobile phone" are broad keywords, where the search intent is typically broad.
Long-tail Keywords are more specific, longer keyword phrases, usually consisting of three or more words. They have lower search volumes but typically have clearer search intent, leading to higher conversion rates. For example, phrases like "men's running shoes size 11" or "Samsung Galaxy S21 user reviews" are long-tail keywords.
