About a book and promoted in weblog
A Website should be ground zero for a book business, the place where everyone comes to buy a book in your site then is better to give them a contact information, and just learn about your book and why they should buy it. It is the single most important aspect of your marketing plan.
To get a great website and make your book like a professional sellers probably you have to invest the money in a professional Web developer, someone who can design a nicely, beautiful site, build your e-commerce system and give you the means to easily update your site content at any time.
Good sites all make the books and their authors appear professional, legitimate, and smart. They are inviting information centers for people to come to and spend time getting to know both book and writer. You should have your Website up and running before you begin any Page Rank or sales activities, probably at least two months before your book hits the media such as sample your book in print and on the Internet.
If you have a website or weblog, it is a simple. Just take a chapter from your book, paste it into its own file with the proper copyright information so it is a self contained document, turn it into a PDF and place it on your website and weblog for free downloading. Then send an email to your entire list offering them an excerpt from your upcoming a book for free.
