Short tail keywords are 3 words or less. Examples include: “athletic apparel,” “DVD player,” or “engagement ring.” Short tail keywords are also known as “head” terms. They may be the first thing you think of when you are deciding where to go to eat (“Chinese food,” “pizza delivery”), what to do (“dance clubs,” “roller coaster park”), or where to worship (“synagogue,” “Catholic church”).
Long tail keywords however are a little different compared to short tail keywords. These keywords are more than 3 words. They are definitely a lot more targeted and not as broad. You may not bring in as much search traffic from long tail keywords but the traffic you do bring in is the kind you are looking for.

Examples of long tail keywords include: “summer women’s athletic apparel,” “super Blu Ray HD DVD combo player,” or “white diamond engagement ring.” Long tail keywords are obviously a lot more specific than short tail keywords; as a marketer this actually can work very much in your favor. But there are pros and cons to both types of keywords.
