Is there a product or service that you are particularly enthusiastic about? If you are, you may be able to develop a website that is built around selling it. You don’t have to be the actual provider of the product or service either. There are many businesses that offer these products and will allow you to sell them on an affiliate basis. For example, you may be able to sell a product on your website for a commission of 20% or 30% of the sale price.
You may decide to create free videos as extra content for your blog, and not sell them at all. If this is the case then you can still make money from these videos by selling advertising space on them (in the same way as discussed for monetizing podcasts). Once you have high volumes of traffic visiting your blog, and watching your videos, you can charge businesses to advertise at the beginning of your videos. Use website’s like Izea to help you connect with companies willing to pay to advertise on your blog.
Haha good question. There are some dodgy ‘gurus’ out there but there’s also so much info for free, so I recommend doing as much research as you can (which it sounds like you’re doing) before paying for a course and you will get an idea of who to trust. The Selling Family free intro course linked above is good, it is American but the basic principles are the same. Matt Webley at the Secret Wealth Project is also very good and I think he has a free FBA course. The Secret Wealth Project Facebook group is a great community, very motivating and mostly UK based so it’s useful to pick up tips on where to source your stock etc. Good luck!
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
