Aren't keywords supposed to be separated by a comma?

No

This isn’t an expository list, but rather a single topic of lengthy wording. Breaking the thing up with commas defeats the single topic point.

What is an expository list?

eg. I am old, mean, grumpy, tired, spiteful, tedious, opinionated.

I’m just trying to understand the difference, and how the process works. I mean, when we post topics in our question, Fluther tells us to separate with a comma. I’ve heard on other places, “Separate keywords with a comma.” Just looking for some education on the subject.

That was exposition. When those words appear on my tombstone, no commas will br included (they charge you for them). I forgot cheap.

OK, so keying in any one of the words should (theoretically) help direct people to his site?
