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.

Given that I am still in reading and preparation phase, I am mainly interested to overlap my niche with real life interests so I could have motivation to produce content on regular basis. Two that I am highly interested are PC parts and Fitness. I am aware they are too general subjects with lot of sites doing the same, but my idea is to produce constant review on PC parts, Laptops, Mobile devices, Accessories all in different categories, create lists like top5 or 10 under XX budget etc. Similar approach I would use if I I decide to go with Fitness path and divide content training advice, review of fat loss methods, supplementation, nutrition etc. I am aware that this will be a long journey and that it can pass few months before sales start to kick in and that’s the risk I am ready to take. My questions are:
It’s sometimes hard to comprehend just how much people love t-shirts. And with the right niche, marketing, and tools, you can create an online t-shirt business that makes you extra money online while you sleep. (Even Bloomberg and Forbes feature stories from entrepreneurs who've done just that.) Services like TeeSpring make it easier than ever to create a t-shirt drop-shipping business where they handle the sales, printing, and shipping, and you’re only responsible for design and marketing. Or you can even buy into well-established franchise businesses like Rhea Lana that sell fashionable, affordable kids clothing and get the backing of a proven organization to fuel your online sales. For more tips, check out this simple guide to launching and marketing an online clothing store by my friends over at Selz.
JVZoo lets you both host and create landing pages on their own website, so it’s far better suited for professional marketers who want to flood the internet with offers, many of them for courses to make money. You don’t need your own website to participate in JVZoo, but you will need to know how to drive traffic to a landing or squeeze page in order to profit from being a JVZoo affiliate.
There are many ways to get people onto your list. Lead magnets are one such resource. For example, you can build ebooks, checklists and cheat sheets. But you can also do content upgrades, such as PDF versions of an article with added resources in them, four-part video training series, and more. Think about your audience and what you can offer them to better serve them, then treat them with some respect and you'll eventually reap the rewards.
Mechanical Turk is Amazon's take on micro-jobs. These are small miniscule-jobs that you can do for other people, which they call HITs, or Human Intelligence Tasks. These are super simple tasks that anyone can do. Some examples are listing off some URLs with certain kinds of images for one cent, or recording a few phrases with a microphone for 6 cents.
As Target is the second-largest general retailer in the United States, their affiliate program is primarily for American bloggers or publishers who can route visitors to relevant products. Overall, the program works much like Amazon’s does in that publishers (bloggers) get a small commission on sales, but Target’s gigantic product base (over one million items) and high brand recognition make their affiliate program a great option for influencers.
18. CraigsList – Some things don’t ship very well. Other things may make you feel uncomfortable to sell to someone across the country. Anytime you’re selling a large item or something you just don’t want to ship, Craigslist is a great place to go. It’s simple to list your item (again, take good pictures!). If you don’t like the idea of putting your phone number out there, the interested individual can send you a message to your inbox without even getting your email address.
