Keywords the user query volumes of which are lower than those of short-tail keywords and usually consist of three or more words are called long-tail keywords. Since these keywords typically have lower search volumes, their competition in related user queries may also be less fierce. Since these user queries contain more words than short-tail keywords, user intent in related queries can be understood more easily. When these keywords, which constitute the majority of Google queries, are directly targeted by websites, desired traffic can be achieved in a shorter period of time due to a relatively modest level of competition.
