Hi, been doing this a while so here goes.
First off your homepage serves a couple functions.
#1 to get your site indexed
#2 for referal (like from a tv ad or business card)
#3 get you two places in the search engine instead of just one
Here's an example: "custom closets central florida"
http://www.google.com/search?hl=en&q...=Google+Search - (damn google it came through before I wanted it to. I only have temp pages up for this client.....lol) - now I have to keep a page named 111.htm in the site......lol
So your home page should include as many of the keyword phrases for the site as you can squeeze in.
Then each page should have unique metas for the unique product or service.
