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.
Ever since we have opened our doors to the world, there have been more jobs and significant economic growth, but we also have to weather every hurdle thrown at the rest of the world. If you watch the Indian stock market these days, most of it is ruled by FIIs (Foreign Institutional Investors). Therefore, the best we can do is plan for crisis situations in your own home.

Having discussed why it is important to have a second source of Income, let me now highlight some of the sources of a second income or second income ideas. A second source of Income typically means having regular income from a source other than your primary one. This means, if you belong to a salaried class, you might want an income from some other source and if you are from a business class, you might want an income from some other business. You can be as creative as it gets. Some good sources of Income are highlighted below:

Another great way to get started is to identify an area of interest you have. For instance, Robert Duff has been successful in building passive income by selling books on Amazon. Then, go out and start talking to people. Ask them, “What are you struggling with right now? What are your biggest pains? What’s something you wish existed that doesn’t?” That’ll give you some ideas about where to get started.
This is mostly passive once you have it all set up, but it does take a lot of work at the beginning. Real estate investing also requires occasional maintenance. Currently, we invest in a couple of rental properties and earn about $500 profit from each per month. You can read more about my rental properties at MoneySmartLife.com: How and Why I Became a Landlord.
Another benefit of investing in rental properties is the loan pay down. If you obtain a loan to buy the property, each month your tenants are paying off part of the loan. Once the mortgage on the property has been paid off, your cash flow will increase dramatically, allowing your mediocre investment to skyrocket into a full-fledged retirement program.

However, until we get another reset in valuations (I’m calculating a 40% to 50% correction is justified ), I’ve moved largely to the sidelines. Beginning in July 2013, I began slowly reducing equity exposure and am now sitting firm at 40% with the balance in various forms of 5 yr cd’s and short duration bonds. This is down from over 60% when I ramped up to take advantage of the March 2009 lows.
In focusing on your wealth management goals, investment income is obviously critical but you might fund your goals from wider sources of income.  A typical long-term portfolio might produce about half its return as income and the other half as capital growth, though in times of duress the capital growth component wanes.  In this low-interest rate climate, some sources of income have become quite expensive and may prove disappointing against your spending needs.  But by tax efficiently and sustainably drawing income from wider sources, you might meet your goals while more prudently balancing risk against reward.
