A long tail keyword is a keyword/phrase which is usually longer than a regular keyword. The intent of such long tail keywords is very specific to the product/service an advertiser is running the campaign for. For example, a short tail keyword lawyer is generic, but a long tail keyword family lawyer in California is specific. Competition for long tail keywords may be relatively lower than it is for short tail keywords as very few advertisers focus on them in their campaigns. It is highly recommended to include long tail keywords while creating an AdWords search campaign as it would help getting more relevant traffic at the same buget.
It has been observed fairly regularly that conversion ratios are higher for campaigns with long tail keywords. This can be attributed to the fact that the intent of such keywords are very specific to the product/service offered. Long tail keywords has an interesting compound effect in reducing the cost per conversion owing to a lower cost per click due to the highly relevant ads. It also helps that most advertisers bid only for the top level keywords instead of long tail keywords thereby making long tail keywords cheaper.
