Great advice here. The typical idea of writing reviews of bicycle pedals and expecting someone to follow your link in order to buy a pair is dead. Now if you are actually a cyclists, and you know something about all the different types of pedals, and why different types solve different cycling problems, then hey, welcome to the world of providing useful content.
Many new affiliate marketers like to use the Amazon Associates Affiliate Program as their first way to start earning a living online. This is actually a great choice! Amazon is trusted by almost everyone and most people you refer to Amazon will already have an account on Amazon. This lowers the barrier to a sale. Many affiliate marketers earn a full-time living just by using the Amazon Associates affiliate program, but it has to be done right. Here are some tips and tricks to earning substantial earnings using the Amazon Associates Program.

Building trust with your audience is paramount in affiliate marketing, and the quickest way to lose trust is to recommend products either you haven’t used before or that aren’t a good fit for your audience. Also make sure you never tell anyone to directly buy a product, you are simply recommending the product. The more helpful you are and the more you make quality recommendations, the more likely your web visitors will come back for your expertise. 
This is a HUGE one! A lot of people register for Amazon Associates at the beginning of their blogging career because they assume it’s just good to “get it out of the way”. Don’t!! *foams at the mouth* I repeat: don’t register until your blog is reasonably established and you’re quite certain someone out there will buy something off of your link. If you don’t net any sales within your first 90 days, your account will get shut down. You’re welcome to apply again, but by then, your fragile ego will be in ruins.

In electronic commerce, means of achieving greater market penetration through websites who target specific groups of internet users. For example, Amazon.com (which sells books, electronics, pharmaceuticals, toys, and many other items) has thousands of affiliated interest specific websites from where the visitors can reach products offered by Amazon. The entire sales transaction takes place at Amazon's website which is equipped to handle the complete online payment acceptance process. Amazon passes on a percentage of the sold item's price as commission to the affiliate website from where the sale originated.
A year ago, when I ran an ABestWeb contest for the best definition of affiliate marketing, Chris, who ended up winning the first prize, summarized things both eloquently and beautifully. He defined affiliate marketing as “the art of doing a merchant’s marketing better than they can, and profiting from it.” Many successful affiliates (also known as super affiliates) are truly better experts in what they do that most of the merchants that they promote. Consequently, they can market e-tailers’ products/services in such a way that merchants get incremental business, while they themselves make a good living off the per sale commission they get.
Websites consisting mostly of affiliate links have previously held a negative reputation for underdelivering quality content. In 2005 there were active changes made by Google, where certain websites were labeled as "thin affiliates".[34] Such websites were either removed from Google's index or were relocated within the results page (i.e., moved from the top-most results to a lower position). To avoid this categorization, affiliate marketer webmasters must create quality content on their websites that distinguishes their work from the work of spammers or banner farms, which only contain links leading to merchant sites.
Cost per click was more common in the early days of affiliate marketing but has diminished in use over time due to click fraud issues very similar to the click fraud issues modern search engines are facing today. Contextual advertising programs are not considered in the statistic pertaining to the diminished use of cost per click, as it is uncertain if contextual advertising can be considered affiliate marketing.

Aside from the obvious advantages of running your own business, being able to work online from anywhere at any time, and having the freedom to choose just how hard you work, there are a few other perks. Affiliates with a strong social following (also known as influencers) can expect to receive freebies from advertisers looking to boost their brand awareness.
A quick and inexpensive method of making money without the hassle of actually selling a product, affiliate marketing has an undeniable draw for those looking to increase their income online. But how does an affiliate get paid after linking the seller to the consumer? The answer is complicated. The consumer doesn’t always need to buy the product for the affiliate to get a kickback. Depending on the program, the affiliate’s contribution to the seller’s sales will be measured differently. The affiliate may get paid in various ways:
Start a new Facebook group in niche area and start recruiting people through paid advertising on Facebook to “like” your page. Paying Facebook for followers can be extremely cheap. I grew my Facebook following on DogFoodInsider.com to 25,000 followers at under 1 cent per like. The trick is, you have to be super targeted. My ad for DogFoodInsider.com simply said this…
Fun fact: the “Amazon Associates” program actually has a different program for a variety of different countries, meaning yes, Amazon.COM has a different program than Amazon.CA, and Amazon.CO.UK, and Amazon.FR, etc. etc. If you want to, you can sign up for all of them without being residents of these countries. What’s important is where your readers are from.
Thanks for reading, Charmaine! I’m not sure about Hong Kong-specific affiliate programs, but what I would say is that most retailers do have an affiliate program in place, so if there’s a particular HK brand or company you use a lot, Google their name + affiliate program to see if they have one. Besides that, the ones I suggested are open to you regardless of where you’re from!
It works for me & I've used it myself. It's really hard to promote something you haven't personally used and loved. A good example of this for me would be FlexJobs. I get a lot of questions about this program. If someone asks me where to find something in the dashboard, I can tell them. If they tell me they aren't finding ANY jobs to apply to, I can provide them with a list of steps that may change that. If they ask me if I pay for a membership myself, I can, with 100% honesty, say YES.

Ooh that makes sense! Yeah, surname would probably be a big one. I’ve also heard that they keep tabs on any old addresses you’ve registered and if the address is the same as someone buying from you, then that doesn’t count either. I can’t imagine they’d be able to know who ALL your friends are, but a good thing to be mindful of! When I first started I thought, hey, why not just make a FB post and tell everyone to buy off me? haha then I realized maybe it’s not that simple.
Another compelling aspect of affiliate marketing is that it lets you be creative, and provide something genuinely useful to your audience. Since you can use affiliate links pretty much anywhere, you can set up a review site, publish long-form articles, or even produce video content. Since you’re promoting other companies’ products, you don’t even need to worry about actually creating, shipping, and supporting the items yourself.
Some advertisers offer multi-tier programs that distribute commission into a hierarchical referral network of sign-ups and sub-partners. In practical terms, publisher "A" signs up to the program with an advertiser and gets rewarded for the agreed activity conducted by a referred visitor. If publisher "A" attracts publishers "B" and "C" to sign up for the same program using his sign-up code, all future activities performed by publishers "B" and "C" will result in additional commission (at a lower rate) for publisher "A".
Creating blog content is a very useful and effective way of consistently building content on a site. When creating blog posts, it's a good idea to do some keyword research to figure out what it is that your audience is interested in and searching for online. Also, be sure to research competitors, forums and social media to narrow down on topics for your blog. 
Amazon has already made similar adjustments in many overseas markets. In 2015, the company moved its European affiliate program to a category-based structure, and according to the affiliate management firm GeniusLink, the result was more of a subtle chill than a freeze-out. “There’s definitely some pain as a result of it,” says GeniusLink CEO Jesse Lakes, “but we haven’t had a single client who stopped doing business because of the new payout structure.”
A lot of people don’t realize this, but you can’t just become an affiliate – it’s a process that requires an application. Even once you’re part of an affiliate network, you’ll still need to apply for individual brands within those networks. There are times when you’ll be declined… usually there’s a reason why (lol like that time I applied to hundreds of clothing retailers in anticipation for all the packing lists that I still have not written). Other times, you’ll feel like a good fit and they’ll reject you anyway. That’s the way this cookie crumbles, so remember to put a little effort into your applications and really pick companies that fit your blog.

In 2006, the most active sectors for affiliate marketing were the adult gambling, retail industries and file-sharing services.[21]:149–150 The three sectors expected to experience the greatest growth are the mobile phone, finance, and travel sectors.[21] Soon after these sectors came the entertainment (particularly gaming) and Internet-related services (particularly broadband) sectors. Also several of the affiliate solution providers expect to see increased interest from business-to-business marketers and advertisers in using affiliate marketing as part of their mix.[21]:149–150
