Hypertext Markup Language (HTML) is the standard markup language for creating web pages and web applications. This step is important to keep your costs down and still get what you want. If you're not familiar with basic HTML and basic concepts about running a website, invest in the time to learn; it will be well worth the outlay in the long run. Even if the site is basically a template for you to use, you're still going to need to know how to insert images, create hyperlinks, and do some text formatting.
Take good pictures. Some of the options below don’t require you to actually take the picture and sell the product, but for the ones that do, make sure you take a clear picture that makes your product stand out from the others. If you’re going to be taking a lot of pictures, set up a small “studio-like” area in your home with a backdrop and proper lighting to really make your pictures come across as professional. And of course, you’ll want a good camera too.
Another way to find this information is to do a simple Google search. For example, one could place the following phrase into Google Search: “(product name) + affiliate program”. (Replace “product name” with the name of the product you are promoting.) There is an interesting chrome addon called Affilitizer is available which makes this process easy.
Now, making money online should seem like a pleasurable activity. Why wouldn't we do just about anything to see things through, since it would be a major source of pleasure, right? Wrong. In the beginning, like anything else, we might get really excited about it. We might also set our hopes very high. But that all comes crashing down when we begin to fail.
– Project Payday is one of those sites that has testimonials of people who have earned thousands of dollars by getting paid to get trial offers. I’m not saying you’ll earn thousands, but it is legit and you can earn some extra cash. They assume that by paying you to do a free trial, you’ll either like the product and purchase it, or forget to cancel the trial and get charged for it. If you can keep track and cancel before you get charged (if you don’t want the product), then this is a great site for making some money.
I have seen Amazon affiliate sites that were so poorly done they made nothing or maybe were lucky to earn $20 to $30 per month. And I have seen some that make well over $1000 per month. But if you speak with experienced Amazon affiliates they will tell you that the average is probably somewhere around $300 to $500 month, per site, which is why most of the pros have ten or more sites.
17. Amazon – Have you heard of FBA? It stands for “Fulfilled by Amazon” and it’s getting pretty popular. Basically, you buy products (in bulk is best) and ship them to Amazon for them to store. When your products sell, Amazon packs them up, ships them out and sends you the money (after taking their cut). There are people making a full-time living from FBA, while others just do it for some extra money.
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. 
I do this because I want to build a solid reputation and a loyal readership of people who trust me. I’d rather make less money and still have a reader than make lots of money and never see the reader again. For me, this comes not only from my ethics but my belief that in the long term building a good profile and reputation leads to other opportunities for profit.
I have a free WordPress website with 1000-2000 visitors/month. I was trying to place Amazon Affiliate ad links last night and failed/flailed mightily. I would paste the links into my posts in the HTML mode, switch to Visual mode, and could see the image. However, every time I tried to save or update the post, the image reverted to the gangly hyperlink. As some suggested, I tried cleaning the links of any formatting from the copy and paste with text edit. No dice.
