1) is there a difference in terms of effectiveness between the following tags:
<meta name="keywords" content="soft, serve, ice, cream">
<meta name="keywords" content="soft serve, ice cream">
<meta name="keywords" content="soft serve ice cream">

2) is one way or another a better strategy? for example...
<meta name="keywords" content="strawberry ice cream, chocolate ice cream, vanilla ice cream">
-vs-
<meta name="keywords" content="ice, cream, strawberry, chocolate, vanilla">

I've been through the guides, but cannot find any straight-forward answers on this. Thanks for any help! -- praxis
