As an internet entrepreneur, you'll need your own web presence:website, blog, social media platforms, landing pages, sales pages, banner ads, or e-commerce site.

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!).

Learn then selling guidelines. Each marketplace has guidelines that define what you can and cannot sell. State and federal laws also impact what items are prohibited.

Salvage and resell. Do you love antiques or have a knack for finding valuables at flea markets or yard sales? If you do, it might be time to consider salvaging items for resale – or even scouting out antiques to sell for a profit. While you’ll need to spend quite a bit of time searching for prospects and spend some money buying upfront, you could easily turn a profit if you know what you’re doing.
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.

This has become a popular business model for online entrepreneurs over the past several years, and will probably just continue to grow in popularity.
