“Many people talk about ‘finding’ a niche as if it were something under a rock or at the end of the rainbow, ready-made. That's nonsense,” says Lynda Falkenstein, author of Nichecraft: Using Your Specialness to Focus Your Business, Corner Your Market and Make Customers Seek You Out. Good niches don't just fall into your lap; they must be carefully crafted.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Become an Email Segmentation Whiz—if you haven’t yet mastered email segmentation, it’s time to learn. Email segmentation simply refers to dividing up your email list into different groups. This might be based on how you acquire their email address, what they click on in your emails, or other criteria chosen by your marketing department to reflect their particular potential pain point. According to email marketing provider Mailchimp, segmented emails have a 14.31% higher open rate than non-segmented emails. Even more compelling, segmented emails have a 100.95% higher click rate than non-segmented emails!
So happy to see Jam Maker on this list. I recently started my own business making and selling unique jams and jellies online. I never knew I was trendy. Many good ideas on here.

Running and charging for webinars can be a great way to build a following in your niche, demonstrate that you are an expert in your field, and make a profit. Hosting a webinar can be hard work. They need to first be promoted, provide original and valuable information, and include interactive elements so your audience can ask questions and engage with your topic. However, once you have built up a large blog following, each webinar can be extremely profitable.
To do that, you have to harbor a few fundamental guiding principles in your mind. Today, if you're at all serious about generating a full-time income (and more) from your online activities, then you need to focus on passive income as opposed to active income. Sure, the active income will help you survive. That's the scarcity mentality at play. But it's the passive income ideas that will help you thrive.
No one likes doing taxes, and they need to be paid whether the economy is booming or tanking. This is why at-home tax preparation can be a great business for anyone with a tax background, or anyone willing to take training courses. Since there are annual changes to the tax code, you will need to refresh your training each year, and you will also need to register with the IRS as a tax preparer. This is more of a seasonal business than a year-round endeavor, but it can be a great way to earn some extra income each winter/spring. Median salary: $30,900.
These days, the trend is toward smaller niches. Targeting teenagers isn’t specific enough; targeting male, African American teenagers with family incomes of $40,000 and up is.
