Provide a service.Those with an interest in writing, graphic design and social media, among other skills, can transform their marketable skills into an online service business. Building a portfolio showcasing the quality and capability of work is essential in helping potential clients make an informed hiring decision. A professional website is a crucial asset in attracting clients. Marketing one’s services and steadily applying to relevant projects through online job boards is a necessary component of starting and maintaining a successful and profitable online service business.2. Flip Blogs.Starting a blog flipping business requires a multitude of skills, making it a perfect business opportunity for a jack-of-all-trades. Those that dabble in website design, online marketing, writing and SEO are generally able to experience the most success in this line of work. The first step in creating a blog flipping business is purchasing existing blogs that have potential but are under-monetized and are in general need of a rehab. Then several months of continuous work is required to bring the blog’s income, design and traffic up to par with expectations. Finally, the blog can be sold to an interested buyer through an online marketplace or private sale. A successfully flipped blog can generally sell for up to 10 times the current monthly income.3. Sell Handcrafted items.Nearly everyone has a hobby that can be turned into an income-producing online business. Crafters that make items such as quilts, cloth diapers, jewelry and other handmade items in their spare time can create a business by selling their handmade goods to online shoppers. Indie marketplaces can help place handcrafted items in front of thousands of hungry buyers daily. In order to increase the chances of success, sellers should educate themselves on online marketing methods, taking quality product photography and shipping practices. Learning these seemingly mundane skills is often the difference between success and failure.There are thousands of online business ideas to choose from – some with a higher startup cost than others. However, the most profitable online business ideas will generally be the ones that are centered on a personal passion or an enjoyable skill. Building an online business requires countless hours of work and enduring frustrating learning curves, therefore choosing something enjoyable will make the hours pass by faster than plunging into foreign waters for the simple sake of profit.
