Others may define it more narrowly, but to me, PPC arbitrage basically involves setting up PPC ads (via Google AdWords or similar platform) and directing the traffic that results from ad clicks to a landing page or straight to an affiliate link (which many platforms don’t allow anymore).  The goal is obviously to earn more from the affiliate income than spent on the ad clicks.  You aren’t adding any value, but merely earning more from traffic than what it costs you to generate that traffic.

Distribution of family income - Gini index measures the degree of inequality in the distribution of family income in a country. The more nearly equal a country's income distribution, the lower its Gini index, e.g., a Scandinavian country with an index of 25. The more unequal a country's income distribution, the higher its Gini index, e.g., a Sub-Saharan country with an index of 50. If income were distributed with perfect equality the index would be zero; if income were distributed with perfect inequality, the index would be 100.
Well written piece, but I question the core premise. Why the fascination with maximizing “income” (passive or otherwise). Shouldn’t the goal simply be to maximize long-term after tax growth of your entire portfolio? If this takes the form of dividend paying stocks, so be it. But what if small caps are poised to outperform? What if you want to take Buffet’s or Bogle’s advice and just buy a broad market index like the S&P 500, (no matter what the dividend because you’ll just have it automatically reinvested to avoid the transaction fees).
Almost all of these ideas require starting a personal blog or website. But the great thing about that is that it's incredibly cheap to do. We recommend using Bluehost to get started. You get a free domain name and hosting starts at just $2.95 per month - a deal that you won't find many other places online! You can afford that to start building a passive income stream.
So how do you get started with the EP Model? First, you need to be an expert in the eyes of those you’re looking to serve. And again, you don’t need all those qualifications and credentials. A lot of people gain expertise and credibility just by sharing their experience learning something, which is something I’ve done on SPI.com. If you think about it, many people in the personal finance or fitness space establish their authority by sharing their journey and their process. They do it by sharing their experiences—and you can do the same thing, too.
Do you know Music ? Are you an expert in Maths ? Vedic Maths ? Yoga or may be cooking ? Do you live in a residential society which has 100’s of other families? Then tutions is a perfect thing you can start give you are good at what you claim to. You can always dedicate 2 hours (if you really have them) and do some basic advertising in your apartment or nearby places and take students to teach them at home. The best part of this kind of tutors is that you refresh your dying knowledge, earn some money at the comfort of your home and you kill time which goes into unproductive things most of the times. myprivatetutor.com is a good place to register and start with.

6) Always Remember That Everything Is Relative. The best way to determine worthwhile passive income streams is by comparing the likely return (IRR) with the current risk-free rate of return. If I round up, the 10 year bond yield is at 3%. Any new venture should thoroughly beat 3% otherwise you are wasting your efforts since you can earn 3% doing nothing.
Developing passive income is different. With the exception of one of my passive income streams (cryptocurrency mining), all of the others require real, hard work. Truly, I understand the barriers for people getting into building alternative income streams. I would say that most people WANT passive income, but truly aren’t willing to put in the blood, sweat, and tears to make it happen.
Capital growth in your portfolio can offset the eroding effect of inflation.  But any capital gains that exceed the overall inflationary effect can be drawn off to augment your portfolio income.  Of course, you must first generate those gains by making thoughtful investment selections.  While allowing strongly growing assets to keep doing that, it is prudent not to allow them to become a dangerously large part of your portfolio lest they go off the boil.  So if you selectively trim profitable positions along the way, you can boost your income.
