1. These are definitely the 2 most common, but anywhere you can use an affiliate link, you can make money. I see a lot of people spamming Quora with affiliate links but wouldn’t advise it. People who will actually buy the product through your link are the ones you will educate on why they should buy it. You need your own platform somewhere and blogs/YouTube and usually best.
If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.
Thank you for all the information. I currently work in a tax and accounting office but want a change. I love the payroll and accounting side of my job but don’t like tax season. It’s high stress and I am not getting the training to get better at tax preparation. I’m 55 and have worked here for 9 years. I also feel like my earning potential will not increase. I really want a remote job. I have the skills and discipline to work independently. Can you point me in the right direction? I’m very good with Quickbooks and Excel. Some of the postings ask for Quickbooks online. I do use it some but wonder if I should get certified. Oh, I also like to crochet and make things. Any suggestions for selling handmade items.
