I'm going to write and sell an ebook on how to start a particular small business. The sales page is not ready, nor is the ebook, but I figure I might as well SEO a basic site starting now so that when the book is ready it has a high ranking site for promotion from day 1. So I figure here's the plan: 1. Buy domain. 2. Write two articles about the subject. 3. Buy linkwheel ($100?) for keywords. 4. Build a few backlinks from blogs, etc. 5. When sales page is ready, erase two articles, and replace with sales page. Is this a logical SEO plan? My worry is that when I delete the two articles and substitute with a sales page, the site will lose its ranking.
