Hey Jan, glad it made you think. As you've found out it's not easy to rank #1 on Google especially when so few people will link to your product reviews. You need to tackle a specific niche with a focused target audience as a whole and build a community of like minded people around your site in order to make any significant income online sustainably and for the long term.
Is this because WP is now blocking outside adds on free accounts? WP recent advised users that ads may appear on free accounts. I saw that WP has a plugin just for Amazon posts, but any plugin requires a business account. In looking at the pay-to-play WP account details, it looks like one has to buy the second level account in order to “monetize your website”.
Understand how a niche website works. A niche website focuses on very targeted, specific information. The content must be specific, useful and interesting to your target audience. Successful niche websites get anywhere from 1,000 to 10,000 visitors per month. You build content on a particular keyword, and you make passive income with Google Adsense or through affiliate links.
This is a very polished and well made plugin – everything operates exactly as it should, easy to configure with a good amount of customization options. The resulting output looks good and should fit in well with any theme you choose to use – having the option to tweak it with some custom CSS is a bonus if something is not displaying quite right for you. Including Amazon links in your posts can be quite lucrative, I personally have earned a lot of money from the Associates program – if you have a website or blog which talks about products quite often, using this plugin can add an extra later of monetization to your site. I found that over Christmas and Black friday sales go through the roof so by using this plugin you should be able to make some extra money which in turn will pay for the plugin cost. I found the plugin developer friendly and helpful in the course of reviewing this plugin so you will be in good hands if you ever require any support.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent.

8. Huge Array of Products — What initially attracted me to Amazons Affiliate program was the breadth of products that they had in their system. This is a great thing if youre niche is narrow or quite obscure as many niche marketers find it difficult to find affiliate programs to match their niche focus. Even if your niche is so narrow you cant find products, at least there are books about it. Not counting books, movies and music, Amazon has over 400,000 different products for sale in hundreds of categories and sub-categories.

Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income? Invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop.
However, like anything else truly worthwhile, apps require a significant investment of your time or money upfront. If you don't have the skills, then you have to hire someone who can assist you in creating a great app. But first you need to come up with an idea that will sell. Do the proper market research and analytics to come up with the right app.
You could also opt to use existing websites for making money. These include both active income and passive income methods. For example, you could sell some used items or invest in creating some digital designs that then can be sold on merchandise. Again, devote a sizable portion of your time to passive income so that you can slowly build up earnings that will arrive on autopilot without any extra added effort.
Affiliate marketing is an ideal solution for those looking to gain control of their own income by focusing on performance-based revenue options. Working in tandem with a seller, a motivated affiliate marketer will be able to achieve a passive income from the comfort of their home without worrying about producing their own product or service. Although the success of the job does depend on the affiliate’s marketing skills, it can prove to be an effective way to meet your income goals as either a primary career or a profitable second job.
