The internet is full of Substack vs Medium comparisons written by people who've used one platform for a month. This isn't one of those.

I've been writing on Medium since before it had a partner program, and on Substack since near its early days. I've earned money on both, grown audiences on both, and hit dead ends on both. What follows is what I actually know — not what the platforms say about themselves.

The short version: Substack and Medium are solving different problems. The longer version is what will actually help you decide.

They are fundamentally different products

This sounds obvious, but most comparisons miss it.

Medium is a publishing platform and reading app. Readers come to Medium to discover articles. Your content lives in a shared ecosystem, competing for attention against thousands of other writers. You grow by being discovered within the Medium platform — via curation, recommendations, and the Partner Program's algorithmic push.

Substack is an email newsletter platform that also happens to publish posts publicly on the web. Your readers opt in specifically to you. They're not browsing a feed — they're choosing to have your writing land in their inbox. That's a fundamentally different relationship.

One platform is about discovery. The other is about loyalty. You need both, which is why many writers — including me — use both.

Monetization: the real numbers

Medium pays you based on reading time from paying members. The numbers have gotten harder to predict over the years. In 2026, most writers earn between one and five dollars per thousand views, depending on how much of their audience consists of paying Medium members. A few top writers earn more. Most earn less.

Substack's model is different. You set your own subscription price — typically five to ten dollars per month — and Substack takes ten percent. If you convert even a small percentage of free subscribers to paid, you can earn more than Medium ever paid you.

But here's the catch: you need subscribers first. Substack's model only works once you have an audience. Medium's model pays you something from day one — tiny amounts, but something.

For a new writer with no existing audience: Medium earns you money faster, but small amounts. Substack earns you more per reader once you have readers, but it takes longer to get there.

Most serious writers I know treat Medium as a marketing channel that also pays a small fee, and Substack as the real business. That's not a bad framework.

SEO and discoverability

This is where it gets interesting, and where most comparisons get it wrong.

Medium has very high domain authority. Articles on Medium can rank well on Google — especially for competitive topics. For years, this was Medium's biggest advantage over personal blogs and newsletters. Publishing on Medium meant instant Google credibility.

Substack has caught up significantly. Substack's domain authority has grown as more serious writers have moved there, and Google now indexes and ranks Substack posts well. I've had Substack posts rank above Medium posts for the same keywords.

The bigger SEO difference is this: on Medium, a high-ranking post sends traffic to Medium, which may or may not convert to your followers. On Substack, a high-ranking post sends traffic directly to your newsletter — where a reader can subscribe right then and there. The funnel is shorter and more efficient.

If you optimize your Substack posts for search — which is very doable — Google traffic can become your primary growth channel. I wrote a full guide on Substack SEO that covers this in detail. Medium can't offer that same efficiency.

Audience ownership

On Medium, you don't own your audience. Followers are Medium's followers. You can't export them, you can't email them directly, and if Medium changes its algorithm or pricing — which it has, repeatedly — your income can drop overnight.

On Substack, you own your subscriber list. You can export every email address at any time. If Substack ever goes under or changes its terms, you take your list and move to another platform. That's not a hypothetical concern — it's happened in the newsletter industry before, and it will happen again.

Audience ownership is the single most important factor for any writer building a long-term business. By that metric, Substack wins — and it's not close.

Content format and tools

Medium's editor is good. Clean, distraction-free, focused on text. It handles images, embedded links, and basic formatting well. It's not trying to be more than a writing tool, and that's a feature, not a bug.

Substack's editor is similar but adds email-specific features: welcome emails, paid content paywalls, podcast publishing, comment threads, and Notes — Substack's social feed. If you want to build a full media product with multiple content types, Substack has more surface area to work with.

Medium's reading experience is arguably better for consuming other people's content. The app is polished, recommendations are decent, and the curated homepage surfaces good writing from writers you don't follow. If you want to read, Medium is still one of the best places to do it.

Substack's reading experience is inbox-first. Some readers love that. Others find newsletter fatigue real and prefer reading at Medium on their own schedule.

Community and social features

Substack has made a major push into community features in the past few years. Notes, threaded comments, subscriber chats, and recommended posts create a social layer that Medium never really had.

Medium has responses (comments), but they're buried and rarely drive real conversation. Medium's social features have always been an afterthought.

If community and direct reader relationships matter to you — and they should, because that's how you retain paid subscribers — Substack wins this category decisively.

Which platform should you choose in 2026?

The honest answer: you don't have to choose. The most effective strategy for most writers is to use both.

Use Substack as your home base. Build your email list there. Optimize your posts for Google. Engage with your readers in comments and Notes. This is your real business.

Use Medium as a distribution channel. Republish your Substack posts on Medium with a canonical link — so Google credits your Substack as the original. Let Medium's audience discover your work. Some of them will follow the link and subscribe to your newsletter.

This dual-platform approach gives you the best of both worlds: Substack's audience ownership and monetization upside, Medium's built-in discoverability and domain authority. I put the exact workflow into my Dual Strategy guide if you want the step-by-step.

If you can only pick one: choose Substack. Email lists compound. Discovery platforms change their rules. Own your audience.

Conclusion

Substack is better for building a sustainable writing business in 2026. Medium is better for getting discovered quickly and earning small amounts from day one. The ideal strategy uses both.
