Social Media Marketing is Networking Online!
Personally, I think that this is the most useful online advertising avenue. If you are an expert in a certain industry, or you have lots of information to offer your customers, then this online marketing avenue is a must for your business.
Basically, Content Marketing is a method of writing articles and other informative pages to better inform your target market. You could literally write about anything that you desire. But of course, make it relevant to what you are trying to sell! By providing free information to your target group, you provide relevant information about your business. If a potential client wants to find out more they will seek out your expertise.
