Ebay is a bellwether. It's been around since nearly the start of the online boom. But, like any other platform, success can seem fleeting if you don't know what you're doing. Selling items on eBay, professionally that is, can be an art form. Getting people interested in your auctions isn't always easy, especially when there's hefty competition and low demand for what you're selling.
If you have a yard or some space to grow food, you could grow items to sell to your friends and neighbors. If you have enough space to grow a lot of food, you could even join a Community Supported Agriculture – where local farmers and residents pool together to buy and sell fresh produce. This may not make you a millionaire, but if you have enough to sell consistently, it could be a great income stream.
If you are a professional photographer or have a real flair for photography, then selling your images on other sites could be an idea. This could be done alongside your own photography site, as it is a good way to help get your work viewed by a wider audience. There are numerous stock image websites to contribute to, but choosing a popular high-end site like Shutterstock should ensure your photographs make you some money.
I don’t frequent these forums too often (and there’s often a lot of garbage to sift through), but there are some gems of information here. It’s usually a good place to check on reviews of various SEO software, see what people think about different changes in the MMO world (like when Google changes their ranking algorithm), and other miscellaneous MMO/affiliate marketing topics.
If you are more confident in your skills, you can also market directly to websites and blogs. You can contact the sites by email to market your services. That will also enable you to select the specific types of sites that you are more comfortable working with. Since there are literally thousands of websites and blogs on the web, the potential market is limitless.
