One of the quickest way to promote your product is to create a Hubpage or Squidoo about it.You may also try to create a Google and Facebook Page about your product/opportunity.Then each week or per two week create one page about the related keywords of your site.Remember to place a link to your product in those pages.
Search Engines love such page(hub,squidoo etc.) for reference.If those sites have a link pointing towards your site, page rank as well as the position of the website in the search results for those keywords will automatically increase.
