If you spend even a small amount of time surfing the Internet then you are going to find many different online business ideas and before long it can become quite overwhelming. Just like anything new, there is going to be so much information available but the problem is always knowing which information to listen to and which to ignore; this article covers the 7 fundamental online business ideas which you will come across online.The thing to keep in mind is that each of these ideas will manifest itself in many different forms but no matter what type of online business you are looking to set up you will find that it fits into one or more of these online business ideas. They are the fundamental building blocks of any online business and a good understanding of them will give you the start that most people never have.The 7 Fundamental Online Business IdeasEach of the following online business ideas are based around the 7 different ways of actually making money online. Whatever business you decide to start online it will fit into one of more of the following categories:AdvertisingThe first of the online business ideas is advertising and with this idea you will look to setup a website in some kind of niche. You can then put advertisements on this site that are related to the niche content you have based it around. The key to this idea is making sure you get your targeting right otherwise you are simply going to annoy people who come to your site by trying to advertise them something totally unrelated to their needs; this is a fundamental error and something you should be very cautious of before you even start.ServicesWith this idea you will setup a website that offers some kind of service to people who visit. Now this can be varied from an online gambling site that offers the gambling service to people right through to an online presence for your offline business.The main difference with the latter is that you can either simply use it as an online marketing tool for your offline business or you can totally automate it so that you use your offline brand name to create an entirely separate online business.SubscriptionsThis is my favourite of the online business ideas because it is extremely scalable and in essence fairly easy to setup. There are however a few things to consider before starting this type of model. You need to make sure that whatever you are offering a subscription to has very good content otherwise you can get yourself a bad reputation before you’ve even started. Secondly you need to monitor the subscriptions in detail and offer technical support for anyone that may have problems getting access.ProductsThis idea is fairly self explanatory, you setup a website where you sell products online. These products can be your own products or ones you buy in from a supplier, the only real difference will be the margin you make on each one. Also, it will take longer to get traction with your own products whereas others will probably already have brand awareness.CommissionsThe commissions model is similar to the products model but in this case you simply promote other peoples products and direct them to their website. You have your own affiliate code so that when anyone buys their product you get paid a commission. Effectively you are acting in the same way as a normal offline salesman on commission.LicensingOut of all the online business ideas, this one is probably the most confusing and I have certainly seen it explained in a variety of different ways and unfortunately most of them are incorrect. This idea can come in two different forms, you can either be a licensee or a licensor. In the former case you will take someone else’s brand and use it to promote your own products which you will then sell for a premium online. In the latter case you are the one with the brand that other people license off you and you get paid a fee based on this.This is quite an in depth concept and we have really just touched the surface with this article.Being a BankWhen you look at the different online business ideas you will probably struggle to come up with this one. What I mean by being a bank is that you effectively offer people lines of credit through various mediums online. Once again, this idea can be hard to understand at the beginning but becomes clear when you research in depth.You will have most likely seen companies offering checkout facilities online where you can pay for goods and services through some kind of online transaction. When you look into what actually goes on in this process then you will start to see how this model works but essentially you are being paid interest on money you allow people to borrow for varying periods of time.
