Key-Word Cavalry: How Keywords Work

This isn’t, strictly speaking, something that came up among the key-words that brought searches to my blog. Instead, one of my better blogging friends, Wendy, asked on the very first Key-Word Cavalry post if I could do a post about the key-words themselves.
So here goes:

Google employs a few thousand Internet gremlins, you see. And every time you write something into the search engine, they send you to the web pages that they best think suit your search.

That’s what I used to think. In fact, I still like to think about it that way. Because a lot of what I do just comes naturally.

But, there are supposedly method to the madness, but since I’ll cling to the gremlin theory with my dying breath, I thought I’d refer you to someone else’s blog post that gives some great tips, much better than I could do it.
