I think writing a lot of "high quality and original" articles on a topic like Cars, Furniture, Home Repair, and computer repair on a blog/websites on a daily basis, and using Ads like Adsense, BuySellAds, Amazon Affiliates, and sponsored posts is one of the more affordable ways to make money because Shared web hosting cost about $5-10 a month, and a domain name cost $10 a year, and if it is your first year for the domain name, sometimes it cost $1 or less for a domain name if there is a sale.
You can also use free services like Blogspot/Blogger, and use Adsense, and other ad networks to make money, but you risk Blogspot suddenly shutting down, getting banned, and losing your blogspot.com sub-domain name like blog.blogspot.com.
YouTube is also a good way to make money with YouTube ads, and if you have a lot of subscribers, and views, you can make money from sponsored videos where you get paid by a company to make a video about their products like computer parts.
You can use SEO, guest blogging, social networks like Facebook, Twitter, Vine, Instagram, blogs, and forum to get free traffic to your YouTube Channel and Blogs with ads.
