Every day more people make the decision to start an online business. It may be the benefits of working from home, extra money needed, loss of traditional employment or simply curiosity – the idea of owning an online business can be alluring. The statistics show, however, that more home businesses fail than succeed. But do not despair just yet – knowledge of the common pitfalls can help you map the road to success. Here are 5 common mistakes made by both new and experienced Internet entrepreneurs.Reason #1: The online business was not a good choice.Few Internet entrepreneurs start their first online business with a firm idea of what they are going to make money from. The majority of home business owners will search for an opportunity because of a real or perceived need; since there are many thousands of Internet opportunities to choose from often what happens is the first one to attract a person’s attention is the one they begin their online business journey with. Whether it is an enticing sales page promising the level of income that would address or exceed needs or the type of business matches a personal interest the process of choosing the online business may determine success or failure from the outset.Some opportunities turn out to be deliberate scams or simply “too good to be true”. Other online businesses just turn out to be the wrong fit because some details were unclear until after starting or the entrepreneur misjudged their own knowledge of the business product or service.Reason #2: There was no business plan in place.It can be relatively easy to simply jump into a business opportunity with no business plan in place. It does not take more than a few minutes to sign up and pay for an online business opportunity without planning or research. Of course it stands to reason that if you are responding to an advertisement promoting quick riches with little or no effort it stands to reason that a business plan would not be in sight because it shouldn’t be needed. A business plan maps out the strategy for financing the online business as well as marketing and other important details typically put in place to turn vision into reality. If there is no business plan then either there is no direction or it rests in the hands of others.Reason #3: The business plan was not followed.With a business plan in place there should be guidelines and limits. Exceed your monthly advertising budget and fail to follow through on planned marketing should prompt the realization that either the online business is off track or the business plan requires revision. But unless the Internet entrepreneur is disciplined to follow the business plan they created it can quickly become a useless piece of virtual paper that has no real bearing on direction or success.Reason #4: There was no mentoring or support system in place.Everyone needs some form of support for their online business. A significant contributor to online business success or failure is the support received through means such as coaching, a friend who listens and provides feedback, or a business forum. There are enough ways to offer support that the absence of any should be a warning sign to avoid a particular online opportunity. If an Internet business owner decides not to avail themselves of available support options then they have mostly themselves to blame if things do not proceed as desired.Reason #5: The intangible costs were higher than anticipated.Assuming even just a little conscientious spending, when tangible (i.e. monetary) costs are higher than bugeted there should be no surprises. That is what a business plan and budget is designed for after all – to make the decision to overspend a deliberate one. But in addition to the financial costs of owning and operating an online business there are less tangible ones that can just as easily spell defeat. An example of an intangible cost is the impact on family life caused by working from home instead of outside of it. The reality is that for some people or situations working at home creates interpersonal stress that was likely not fully anticipated and was not part of the picture when they were leaving the house for work.In conclusion, there are many reasons why an online business can fail but knowing about them means they can be avoided. Aiming for success a new or experienced Internet entrepreneur can research business opportunities before joining, develop a workable business plan and follow it, take advantage of the support available and monitor the impact of working from home.
