Could anyone enlighten me as to what long and short tail keywords are and how they can be helpful?

Thanks

Basically I don't believe there is such a thing like long or short keywords. Keywords are not measured by their length and to me, most important is that how popular the keywords are. There are short keywords which are more popular than the longer ones and vice versa. However, you might want to keep it at reasonable length.

The popularity of keywords is more important than the length. Many times shorter keywords are found to be easier to memorize, but that isn't important. People search for what they want, no matter how long the keywords are.

Yes, the main thing is how popular your keyword is. Well maybe to certain extent that shorter keywords have more chances of being popular than longer ones but anyway that doesn't come as an issue here. Just something to take note on it.
