Here’s a good example of how lead sales can work in real life: My second website, Life Insurance by Jeff, brings in a ton of traffic from people who are searching the web to find answers to life insurance questions. While I used to have the website set up so I could sell these people life insurance myself, it was a lot of work to process all the different requests and clients. As a result, I started selling the leads I gathered instead.
Offering specific online SEO services is also another online freelancer role that businesses are crying out for. If you know how to improve a website’s SEO by doing keyword research, creating content that can rank in search engines, adding metadata/schema to posts and pages, and building backlinks to a domain, to name a few tasks, then this could be a great line of work for you.
Please note that some of the links below are affiliate links and at no additional cost to you, I will earn a commission. Know that I only recommend products, tools and learning resources I've personally used and believe are genuinely helpful, not because of the small commissions I make if you decide to purchase them. Most of all, I would never advocate for buying something that you can't afford or that you're not yet ready to implement.
If you have nothing of value to sell from home then retail arbitrage might be a better option for you. Many people partake in arbitrage to earn a little extra money, and for some, it has even become their full-time job. Retail arbitrage is the buying of goods at a low price and then selling them on a different platform at a higher price. Sales in shops provide ideal opportunities to pick up products for next to nothing. These can then be sold on eBay or Amazon for higher amounts, making you a nice profit.
Something else I recommend is taking the free 7-lesson mini-course on general transcription offered by Janet Shaughnessy of Transcribe Anywhere. This will help you to understand if you're a good fit for a transcription career, what you can potentially earn, and also where to get started. Janet also has free legal transcription mini-course if you're more interested in going that route.
