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.
Summary Section: This section is where you will be able to attach or explain any detail not applicable to the previous sections. This section should be used to provide the financial statements of the Principle's involved in the business and any other data you think an investor would be interested in seeing.
Competitive Analysis: Business by nature is competitive, and few businesses are completely new. If there are no competitors, be careful; there may be no market for your products. Expand your concept of competition. If you plan to open the first roller skating rink in town, your competition will include movie theaters, malls, bowling alleys, etc.
Right now, growth may sound like an unattainable goal as businesses are grappling just to survive, but hey, "flat is the new up." If a business can keep its doors open and lights on, then it's doing better than many others. But lights and open doors don't make sales, so making changes that attract business is in a sense, striving for growth. It won't be this tough forever, but for now, putting some growth strategies into action may be what keeps your business alive, if not thriving.
