The easiest and most accessible resource on the Internet is of course the search engines. This is such an amazing technology, and we are so fortunate to have what seems to be an endless stream of information about everything and anything close at hand.

So I bet you know where to start looking for the best business opportunity online.  You could first make a list of possible businesses that seem attractive to you for the products or services that they sell, or that represent the greatest potential for maximum income. That would seem the obvious place to start searching.

However, there is a theory that the intelligent way to find the best business opportunity is actually to find the market first, and then get the product or service that the market is searching for.  This means to find out what the popular trends are.

What is it people are looking for when they go online? (The answer is actually information, but that is for another article, unless you want to go into a business involving information technology or services).

Even if they are considering purchasing something, they are first searching for information about it.  They may want to study the specifications and functions of the product, compare prices, and where to buy it, etc..

Just 'Google It' is a common answer to just about any question, including how to find the best business opportunity online. So we would first take the results of our research into trends, and having found our market, then we would look for the products or services we might want to sell.

So hypothetically, we find that there is a huge market for videos.  We find that many people are interested in buying new or used videos, and that they also like to rent videos.

We then look for the best business opportunity that offers videos. We may find that it is very expensive to buy a franchise business; so then we look for Internet shopping malls that may offer affiliate opportunities, (like eBay, Amazon or ClickBank for example).

If we have any skills or expertise in web design, we might just design a site ourselves, and then start shopping for wholesale videos to feature or link to on our website. 

With the Internet business model, it is not usually necessary to have inventory, and it may be best to find resources that will do drop shipping directly to our customers. 

It depends how much work you want to do, so that would be some of the fine tuning you would need to do in structuring the best business opportunity for you.
