Short tail keyword
Also referred to as “head terms”, short tail keywords are made up of only one or two words. These search phrases tend to be used by searchers looking for very general information on a particular topic. Short tail keywords are often very competitive because they are broad and somewhat vague. An example of a short tail keyword could be “dogs”.
This query would provide information on what a dog is, and perhaps breeds of dogs, but the searcher would need to use a long tail keyword if they wanted more specific information about dog breeds, dog foods, etc.
