It's a jungle out there and, frankly, we don't like getting our hands dirty. Writers are shy, reclusive creatures, who would much rather sit at home, sipping Darjeeling in our pajamas, quietly composing the Great American Novel.
1) Marketing is what you do before you publish. It establishes the need for a product. (An example of marketing - "Coming soon to a theater near you!") Pre-release reviews, cover releases, pre-orders, and interviews prior to releasing your book are all marketing strategies.
2) Promotion is what happens after you publish. It satisfies the need for the product you promoted during your marketing campaign. The product is your book. (An example of promotion - "Now available on DVD!") Advertising, blog tours, free days and giveaways are all promotional strategies.
Whether you are an unpublished neophyte or an author who has hit the big league, marketing - establishing a need for something - is the name of the game. Without it, promotion is like swimming against the tide.
Like any game, marketing has rules.
