If an online business, you need to go into detail how you will attract customers to your website. General statements like "I will use Face Book ads and email marketing" will contribute almost nothing to helping your cause unless you have detailed statistical analysis of tests you have conducted or of another similar business you have been associated with. If you do not have any data upon which you reference your estimates, it could show lack of proper thought to the remainder of your business plan.
Starting a business, whether online or offline is not exactly easy. There are so many things to think of and so many things to do. You have to have enough resources, a good venue, a market to capture and enough workforce to start with. And as if you need more, you also have to worry about licenses, complicated paper works and other permits.
Business plans may target changes in perception and branding by the customer, client, taxpayer, or larger community. When the existing business is to assume a major change or when planning a new venture, a 3 to 5 year business plan is required, since investors will look for their investment return in that timeframe.
You have to do research and you have to put your thought in to it. You have to follow a certain format that will put everything in perspective. Luckily enough, you can find business plans examples or even templates if you just know where to look.
