As for what should your sandbox be, you have a few options. The easiest is to start a blog. That’s what this site was started as: a sandbox for learning content marketing, and it only became my full-time job on accident. A blog is a perfect sandbox for learning digital marketing since you can test almost all of the tactics on it, it’s low-cost, and you’ll improve your writing in the process.
Type of site: Just make this a niche site for the first several years.  Don’t waste a ton of time making a podcast and an in-depth youtube channel.  Make a few videos to show some setups but mostly just write blog posts.  If you create a podcast episode today, nobody will listen to it again after a few months.  Write blog posts that will last.  There is no competition here, so don’t get bogged down with social media and crap.  Just write!
Lending Club is a platform where you can lend your money to other people. You’re the bank. Each note is only $25, so you can invest $1,000 and lend money to 40 people. There are many grades of loan (from safest to riskiest) and investors earn, on average, between 5% and 7% annualized returns. For more information, check out Investing and Making Money with Lending Club Peer-to-Peer Lending and my real money Lending Club Portfolio. 

Residual income is money that is earned on a recurring basis, typically as the result of a single original action. Rather than earning an hourly wage, residual income is typically generated through an initial investment of time or money with the goal of earning continuous payments. Once the initial investment, product, or service is made, the ongoing income that is earned is generally passive in nature.
I just started getting into dirt bikes.  They are SOO much fun!  Unfortunately, I’ve found it difficult to find good answers to the things I’m searching for  on newbie dirt bike topics.  For example, “How many CCs should I get for a kids bike?”  Or “What protective gear do most kids wear for dirt biking” or “What is the best beginner adult dirt bike?”  If you can answer those questions and create a helpful site answering them, it could be quite profitable.
At this point, you probably already know what Facebook is and what it does. What you might not know? It has a training and certification program. Facebook Blueprint offers self-paced and live e-learning courses for marketers seeking to grow their organizations using Facebook. Blueprint offers classes in different languages on how to use Facebook and Instagram -- here's a peek at the course catalog.

This step isn’t strictly necessary, but spending some time freelancing can advance your skills considerably. When you’re trying to help another company or person do what you’ve done on your own, it’ll expose areas that you aren’t as familiar with, and can help you round out your understanding of the skill. And if you’re able to find someone you can freelance for who’s more skilled than you are, they can point out areas for you to improve that you might have missed on your own.
There is a specific tax definition of passive income, known as “passive activity” to the Internal Revenue Service. Passive income is any income you make without actively working or are materially involved. The IRS defines it as any rental activity or any business in which the taxpayer does not “materially participate.” Nonpassive activities, or active activities, are businesses in which the taxpayer works on a regular, continuous, and substantial basis.
Since all google searches that contain “near me” and similar triggers googles own search result inlay with map and everything to suggested place aren’t you competing directly with google then? I might have missed it but this isn’t discussed in the article. Should you skip all search results that are competing with Googles own search result box/area?
Oops, my last sentence should have been “in addition to buying your services and courses” not “except”, it was already after 12 at night here yesterday. Yes, checking niches obsessively is something I can relate too as well. I think I got about some hundred domains I bought after researching new topics but then never found the time to build content for them and really make use of them. After renewing them for two or three years in a row I decided to focus on related niches I can build like more related content for and then also throwing in some useful links in between them. 🙂
great read as always glen, congrats on sharing your research. although i believe strongly in the “rank & rent” concept for local seo marketing, it is interesting that i watched an entire video today by a prominent local seo guru who says r&r sites are the worst possible business. i’m having trouble wrapping my head around that as it goes against what my gut believes but then again, he’s “been there done that” and i haven’t. anyway, i digress big time, great article.

I had to get out. I actually had this random Facebook ad come up in my news feed (go figure) and it eventually led me to a webinar that taught on how to start an email marketing business (which is, by the way, the most profitable form of affiliate marketing – or ANY marketing for that matter). I listened through the whole 2 hours, completely mesmerized. By the end of it, I knew what I was going to be focusing on to help my family out of the pit of debt we were in and into a world free of financial stress. I didn’t know if it would actually work, but eventually it lead to EXCESS income!
My goal with this site is really only to write about 25-30 pages with information as I learn about boats and do customizations to my boat.  I’m also adding a forum.  Forums seem to be very popular with boat owners so I’m anxious to have others generate content for me.  I don’t have huge plans for this site, but I’m sure it will bring in a few thousand a month if I don’t fizzle out.  This is going to be my fun project for the next little while.
