Selecting the "right" keywords/phrases is a
balance between using a very grneral or popular
keyword like "phones" and a very specific
keyword phrase like "NEC Vanguard phones".

Using a very popular keyword means your site
will compete against more websites than the more
specific key phrase. So you want to use key
words that are most appropriate for your
business and target market.

For example, if your business services a specific
geographic area you can use that to focus your
keyword phrase... like "southern Texas phone
systems" instead of "phone systems".
