Short Tail Keywords
Small-tailed keywords include one or two words like 'B2B Marketing'
For marketers, when users were searching for these keywords, they could sometimes be ambiguous. For example, find "B2B marketing", and it is difficult to tell what the user is about to "b2b marketing" which the user wants to know? Maybe they wanted a list of B2B marketing agencies, definition of B2B marketing, or some suggestions about implementing B2B marketing.
Long Tail Keywords
These are three to four words and beyond, often using full sentences. Long tail keywords can be used to help the user with a specific problem solving or asking a question. For example, "How Does Content Fuel Generate?" Or should I outsource my social media management? These keywords are often clicked through a high rate because keywords are more specific and the results are more relevant.
