Just as in an offline business, there are ethics and standards that should be followed. If you are starting an online business, you've probably spent some time online already and can see that there are hundreds of thousands of businesses trying to sell their products and information and services to you. Study how they do it. Spend some time visiting the websites of your competitors, much like you would when preparing a business plan for an offline business. Look for and evaluate the following characteristics to determine the integrity of the business as a whole:

What are they selling?

When you first come to their index page, can you quickly and easily figure out what they are selling? Is it a real product, an information product, a membership or a service? Do they offer something of real value right off the bat for free such as informative content or a related ebook? If you cannot determine within the first 30 seconds what they are selling or why they are in business, chances are that they are just a hodgepodge of links put together to make the owner affiliate revenue. However, if you do see something of value, stay a bit longer and evaluate further.

Can you contact them directly?

Look on the main page. Contact information could be in the top nav bar, on the side nav bar or at the bottom of the page. Also, look for a direct link such as Contact Us. Click this link and see where it takes you. Do they provide a physical address, a contact name or email, and a phone number? These three things are a must for a legitimate business. If an owner is not confident in his business enough to put an address and contact phone number on his site, he must be hiding something. The final test is to send an email to the company and see who responds and how long it takes to get a response. Most one-person web businesses should be able to answer your email within 1-2 business days.

Is the content valuable and correct?

If the owner has done his research and knows what he is talking about, this should show in the quality of the information on his site. A professional image depends on attention to details. Presentation is everything. If you are going to put out information, it has to be presented in an organized fashion with no mistakes
