If you have a propensity for writing and you can slay with your prose, consider writing an ebook. While the market has certainly become saturated as of late, books that help teach people about a technical topic still sell extremely well. This is a great source of passive income but does require a large amount of effort at the outset before any money is generated.
Don’t exhaust all the information about the product with your link. Offer enough information to your readers so they know what the link is, but I don’t recommend giving too much detail on your own site for a two reasons. First, product information, like price, often changes. If you mention the price on your site and someone clicks over and finds a different price, it’s confusing. Second, many times, the product details and features are better explained by the makers of the product. It’s best to stick to your own experience on your site.
Using a food delivery service can’t necessarily earn you money, but it can help you save you money if you constantly find yourself throwing out half the food you buy. Food delivery services send a box of food every week with new, sometimes unique vegetables, meat, fruit, and so on. If you don’t have time to shop and want simple meal-prep that leads to a good meal, a food subscription service may be perfect for you.
Now as to your comment on traffic it is true, traffic is important. But the truth is, acquiring traffic is easier than converting it. Plus we have many posts dedicated to traffic generation on this blog. Simply check this post, this post or this post. But must importantly, the reason why people struggle with traffic is that they try to promote a sales page or a heavily biased piece of content. Nobody wants to share that, nobody wants to link to that, and as a result you don't get traffic and blame your lack of success on traffic (like you did in your comment above).
If my piece of content is so unique and valuable around hiking backpack recommendations, that other reputable outdoor websites are willing to link to it and build the page’s authority, then I’d have a very real opportunity to rank high in organic search for these search terms (meaning, my page will come up first when someone searches for hiking backpacks).
The easiest and most common way to start building an audience for a website is via social media. Depending on your niche and industry, you can choose from Facebook, Twitter, Instagram, Pinterest and several other niche and location-specific networks. Building up an engaged and interested following on social media is a great opportunity to build relationships and once you have their trust, promote your products and services to them.
There absolutely is still room for new affiliates, because there are always new products to promote and new audiences to reach. The internet is a vast place with infinite verticals to work in, so instead of just focusing on the biggest affiliate programs in a specific industry I recommend using that one as well as others (and Amazon!) to round out your affiliate offers and thus your revenue.
Before jumping into starting an affiliate marketing business, learn all that's involved in making it a success. More importantly, if you decide to pursue an affiliate marketing business, or want to add affiliate marketing to an existing business, understand that it's not fast, automatic, nor without effort. Like all home businesses, you need a plan and daily involvement to make money with an online affiliate marketing.
Understand where people are at in the buying cycle and promote accordingly. Spend the most time sharing affiliate links where people are ready to buy. For example, you can share affiliate links on Pinterest, but most people are not on Pinterest to buy but to look. As such, focusing your affiliate marketing strategy on Pinterest might not be the best use of your time. Review posts, for example, might be better at tipping people over the line into buying.
As someone who's been immersed in a number of online industries for quite some time, I know a thing or two about what it takes to succeed in this arena. However, just like you, I started at ground zero with little knowledge, but a great deal of passion. What I learned along the way were some invaluable lessons from failure that hurt at the time, but helped immensely in the grand scheme of things.
