Create a website about the topic that you have chosen. The key to succeeding with affiliate programs is to build a content-rich website with useful information built around a specific theme. Don't just lazily throw up a quick site or blog and string a bunch of affiliate links all over your pages. You have to start by building credibility, and the best way to do that is to write about something you know a lot about.
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.
Garage sale hunting – You can go garage sale hunting and this can be a lot of fun. This can actually help you make money with a hobby. I find this to be a lot of fun. One of the best things I find at garage sales are antiques and antique clothing. A lot of times people don’t realize when something is valuable. So, garage sale hunting is a great way to earn some extra money on Ebay.
Purchase items in bulk and resell them for profit – An example of this is purchasing a bulk order of car chargers for a newly released cell phone. You can usually find a bulk manufacturer in places like China or some other asian countries. You can buy them by the hundreds or thousands and basically pay under $1 for each one, then resell them on Ebay for several dollars. You can still keep it cheap, maybe $5 for an iPhone charger, and if you only paid a dollar for that you’re making a $4 profit.
Once you have that problem or need nailed, the next step is to validate that idea and make sure you’ve actually got customers who will pay for it. This means building a minimum viable product, getting objective feedback from real customers, incorporating updates, testing the market for demand, and getting pricing feedback to ensure there’s enough of a margin between your costs and what consumers are willing to pay.
Understand the different sales models. The most common forms of paid channel advertising are cost-per-mille (CPM) and cost-per-click (CPC). CPM ads are the banners you see across the tops of webpages. You are billed a flat rate based on the number of times the ad is displayed. CPC ads are the paid advertising results you see on a Google search results page or in the side margin on a Facebook page. You pay for every click on your ad.
