Amazon has been my second-best earner after Adsense. I am still in the start-up stages of IM in general but I do get a check from Amazon every month. I agree fully with the reasons you give and I have found that the small commissions is far outweighed by the points you list above. I make far more with Amazon than I do with any other affiliate program though they might have higher commissions.
My third question is: Finally when i have decided the keyword, the next step is to search on Amazon about the baby shower gifts- it shows thousands of searches. Then how am i to decide which product should i choose- if i were writing a post on say ‘cute baby shower gifts’? Should i look at the price of each product which i am going to add in this post? How to decide?
Finally, email every network you are associated with for this website to inform them that you are selling your site and that you want to make sure that the new owner will be approved for that affiliate network. This is an important, if not obvious, step to follow. If a network denies the new buyer, that is going to lead to a lot of trouble when it comes to them taking full ownership over the site.
You must use both a unique public key/private key pair (each key pair, an “Account Identifier”) and an Associates tag parameter (which can be either the Associate ID issued to you under the Amazon Associates Program or a related Associates Program tracking ID) to identify your account and make calls to PA API. You may obtain your Account Identifiers through PA API account creation process.
Small-scale bloggers like Robey won’t be the only ones hit by the rate changes. Publications like The Wirecutter have built thriving businesses entirely on affiliate payments, which are made by vendors like Amazon whenever a referred customer buys a product. Though a number of companies offer similar programs, Amazon’s affiliate system is the most lucrative, and auto-tagged product links have become a significant part of many online businesses’ revenue. (That includes The Verge, which auto-generates affiliate links in some cases.) Though the relationship can be lucrative, it’s also entirely subject to Amazon’s discretion — and as Robey and others are learning, it can often change with little to no warning.
Thanks for your point for point description of what has worked for you. You have certainly given credibility to testing your results. Doing the technical aspect of setting the structured sites and e-mail marketing has been challenging for me. You have clearly described how the more sales you make your percentage goes up and you make more money. Apparently there are tested formulas that work for Amazon sales and getting people to Amazon sounds like a winner.

(b) The Local Associates Products will be made available for Amazon customers to purchase through a specific page on Amazon.com assigned to each Local Associate (such page, the “Recommendations Page”). The Recommendations Page will include either a general Amazon.com search bar or a selection of Local Associates Products curated by you. Amazon reserves the right to modify the Products included in the Local Associates Products on any Recommendations Page. You must direct all Local Associates Program marketing to the Recommendations Page to be eligible for Qualified Purchases.
Once you’ve set up your account, do note that Amazon requires you to use product links and generate income from at least three of them within 180 days. If you fail to do so within that time, they will close your account. If you are able to satisfy that requirement, Amazon will review your account as well as your usage of affiliate links once the first sale is complete. 

A great point you made there though. Too many people try to take on too much at once and end up spreading themselves too thin – trying to conquer all the niches at the same time. Marketers also do this with advertising. Instead of sticking with one platform until they are generating a consistent number of leads they will jump from platform to platform, in essence chucking a load of crap at a wall and seeing what sticks.
I thought I would just bring something else to your attention; I did take a second to look at your site; you know why I left within just one second? EXACTLY! You have less then 3 seconds to make your first impression on visitors; if your visitors are bouncing off your site at the speed of light, they either found your site by mistake, or they were not impressed with your site, and left, which means? right, they did not trust your site!!! What happens if you have a high bounce rate? right, you can certainly lose rankings! Is google going to keep sending you traffic if you have nothing to offer? nope! I can not say this is your problem, or you could have multiple problems going on at the same time to cause you to lose rankings. I can tell you one thing for sure by just taking a 1 minute look at your link profile; You have quite a few links, and you have almost no authority, what does this mean? This most likely means you are spamming your link to poor quality sites. You also have a massive amount of do-follow links which does not look natural vs your no follow links, and with your site having low trust flow, do you think your site deserves that many do-follow links? I wonder what google thinks? at first glance, your anchor/link diversity does not look to bad, so your anchor/text does not look over-optimized, but whoever is building links for you, consider firing them immediately, as you are getting all the wrong links. I am going to assume at this point google has certainly given you a penalty; Your next move to to hire someone to audit your site, and start disavowing/removing bad links from your portfolio, over time, your rankings may come back, and that may depend on other factors also, but at this point, it certainly looks like you have link issues. Just a little bitty research goes a long way. good luck.

As you become comfortable with the affiliate marketing process, you can consider both specialized (e.g. fly fishing) and broad (e.g. weight loss) niches. Don’t forget to track your marketing metrics! They are usually provided by your merchant and/or affiliate network. This way you'll be able to know which products your audience are responding to and which ones aren't generating any profits for your business. This is especially important if you are investing into paid advertising to drive traffic and promote products as an affiliate...
With a little bit of creativity, this business model can be molded into any business. It can be used as a personal moneymaker, as a legitimate company, or even as a supplement for a company already adopting a different business model. As we enter a new era of virtual reality, crypto-currencies, and whatever crazy new tech that comes out think about how you can implement the affiliate marketing model into future businesses. Wake up; we are in a gold rush. 

Smaller and newer e-commerce businesses often find this practice especially appealing (although Amazon.com uses it, too). Unlike pay-per-click advertising, which charges merchants every time someone clicks on a link to their site, affiliate marketing costs nothing unless there is a sale — at which point a commission, typically between 4 and 20 percent, is paid. It has become an essential part of the online marketing toolbox, generating fees that Forrester Research projects will reach $3.4 billion next year.
To build trust, you need to create content that’s honest and sounds natural. There’s a lot of competition in affiliate marketing, and plenty of websites that churn out product reviews sound as if a robot wrote them. If you take the time to carefully research each piece and are honest about a product’s downsides, however, you’ll be able to establish trust organically.
