I Ranked Every Online Business Model (Brutally Honest Tier List)

Let me be upfront: most people never make money online. This is not a guarantee that any of these will work for you. I'm Daniel Fazio — I run a coaching business and a software company called Listkit. Last month we did around $1.58 million in revenue, a substantial chunk of which is profit. I've been in this space for seven or eight years and worked with thousands of people across every kind of offer imaginable.

Here's my raw, honest ranking of the most common online business models.

S-Tier: The Best Opportunities

Specialized Skill Servicing

This is the single most legitimate way to make money. If you already have a skill from your job — accounting, email marketing, media buying, whatever — just go sell that as a service. You already know how to do it. Stop working for someone else and start selling it yourself. Every one of you should be doing this.

Cold Email Agency

You take a B2B client and send cold emails to generate them leads. Most people charge a monthly retainer plus performance fees per call booked. This is consistently one of the most common paths I see people take from zero to five figures a month. B2B companies will always need leads. It's a real, in-demand service.

Ads and Funnels Agency

Look at any marketing agency doing $200k, $300k, or $400k+ a month — nearly all of them are advertising agencies. It's harder to start because you need to actually be good at running ads and building funnels, but it has the highest ceiling of any agency model. If you want to build something massive, this is the path.

Copywriting

Writing sales pages, emails, and ads — sales in print, at scale. It's genuinely difficult to get good at, but the earning potential is astronomical if you pick the right clients. It's one of the most valuable skills you can possibly learn.

Selling a Course

If you have specialized knowledge, selling a course is one of the best businesses you can run. "All course sellers are scams" is nonsense. People buy courses because they want to. There's done-for-you, done-with-you, and do-it-yourself — courses cover the latter two, which represent the majority of services sold on the planet. Sell something real where you genuinely care about results and it's a phenomenal business.

A-Tier: Strong Models With Caveats

Ads and Content Agency

Creating content (usually YouTube) for clients is legitimately great — unless your entire client base is info product creators. Info product people are overindexed on marketing themselves and will resent you taking over that role as you start delivering results. If you can diversify your client base, it's closer to S-tier.

Ecommerce Email Marketing Agency

Send more emails to an e-commerce brand's list, they make more money. Simple. The problem is the barrier to entry is basically zero, so the market is flooded. Getting clients is brutally competitive. The work itself is easy; the sales process is not.

AI Automation Agency

This is legitimate, but it's not for everyone. You need to be a genuinely intelligent person with a deep understanding of operational systems, business processes, and how to communicate with clients. Most businesses you'll encounter don't have clean processes — you're often building everything from scratch. If your IQ is above 120, this is A-tier. If not, be honest with yourself and pick something else.

Affiliate Marketing (CPA)

Buying your own ad traffic, generating leads for an offer (say, health insurance), and selling those leads at a margin — that's a real model. The catch is you don't own the offer, and you have to sift through a lot of garbage to find legitimate ones. Solid, but not life-changing on its own.

TikTok Shop Affiliate

You make videos for e-commerce brands and earn a commission when people buy through TikTok Shop. People genuinely make money doing this. It's a real model. But like remote closing, it's more of a high-paying job than a scalable business.

B-Tier: Decent, But Limited

Remote Closing

Closers on my team at Listkit make $8k–$15k a month. It's real money and a legitimate role. But it's not a business — you can't scale it. If you just want a well-paying job without the stress of running a company, it's essentially S-tier. If you want to get rich, it caps out too early.

Real Estate Wholesaling

Get a property under contract, assign that contract to a buyer, and take an assignment fee. It works, it scales, and people make serious money doing it. But it requires an enormous amount of upfront effort. Legitimate model, just a grind to get started.

Amazon Reselling / Retail Arbitrage

Buy underpriced products at stores like Marshalls, list them on Amazon, pocket the margin. People make a couple thousand a month doing this. It's real, but it's time-intensive and nearly impossible to scale. Good if you just want to make some extra money.

Airbnb (with ownership)

The arbitrage-only version (renting someone else's property) is C-tier at best. But if you're buying the property, the tax advantages change the math significantly — you can depreciate the asset and potentially offset active income from other businesses. With that angle, it's a solid B.

C and D-Tier: Avoid or Be Cautious

Dropshipping

The model itself — fulfilling orders directly from a manufacturer — isn't inherently bad. But it's so saturated with garbage Chinese products that it drags the whole category down. Think of it as a stepping stone into building a real e-commerce brand, not a destination.

Faceless YouTube Channels

YouTube actively works against mass-produced AI content. People run ten channels, get banned constantly, and reset. A real YouTube channel is A-tier. Faceless AI spam channels are C at best.

Selling AI Tools (White Label)

You're not solving a real problem. The pitch is: "rent this AI voice agent to a business." But the businesses you're targeting don't have a flood of incoming calls to automate in the first place — that's exactly why they're struggling. You're trying to optimize a process that doesn't exist. This is the same playbook as white-labeling Go HighLevel. D-tier.

Day Trading

The failure rate is as close to 100% as a legal activity can get. Every rich day trading guru makes their money selling the course, not the trades. You're not going to out-compete billion-dollar hedge funds with fiber optic cables running milliseconds faster than anyone else. Don't do it.

The pattern is simple: the best business models are the ones where you deliver a measurable result to a client who genuinely needs it. Everything else is noise.
