Users perform queries on search engines to find specific results. While these queries sometimes consist of a single word, they may contain multiple words in some cases. Keywords that consist of one or two words, offer the most general framework, and have the highest search volumes are called short-tail keywords. Since these keywords are usually used in open-ended queries, it may be quite difficult to determine user intent in queries these keywords are used. The competition between ranking pages may be fierce, as the search volumes of such keywords are very high. However, websites that manage to achieve a good ranking in the search results of these keywords can drive significant traffic.
