Key Words

i have been using only one key word in the keyword box when building my pages. I hear that it helps a lot to also put in related key words. Is this true and how many key words are helpful and can you overdo it?

Answer
For the most part search engines don't seem to be reading the keyword box anymore. At least that is what a lot of people suspect. But search engines are reading the text on your page, so that is where you need to concentrate your efforts in placing keywords. Use your primary keyword (it is still a good idea to have one), and use as many alternatives as you can think of in the text of your page. As Ken said, we don't really know what the search engines are doing, and it doesn't hurt to use the keyword box, so let's continue to use it too.
