A Substack is a newsletter publication hosted on Substack: every post is a web page and an email to your subscribers, and readers can pay to subscribe. A blog is a collection of articles on a website, usually your own domain, that people find mainly through Google and links. The real difference is distribution: Substack pushes each post to inboxes and to its app's network, while a blog pulls in readers from search, slowly at first and then for years.
Pick Substack if the newsletter itself is the product and you want paid subscribers. Pick a blog if you want search traffic, leads or customers for a business. Plenty of people run both, and below we show how to set that up without doing the work twice.
Key takeaways
- A Substack is inbox-first and network-driven; Substack says more than half of new subscribers come from its own network.
- A blog is search-first: it compounds as pages rank. Across 2,119 sites, Outrank's data shows +7% clicks after 28 days and 2.0× by month 7.
- Substack keeps 10% of paid subscriptions; a blog on your domain earns through ads, affiliates, products or leads with no platform cut.
- Substack gates sitemaps and Search Console verification behind growth; a blog on your own domain gives you full SEO control from day one.
- Most businesses should start a blog; most independent writers selling subscriptions should start a Substack; many end up with both.
What is a Substack?
A Substack is a publication on Substack, the newsletter platform founded in 2017. You write a post once and Substack publishes it at yourname.substack.com and emails it to every subscriber. Readers can subscribe for free or pay a monthly or yearly price the writer sets (at least $5 a month or $30 a year), and Substack keeps 10% of that revenue.
Around the newsletter sits a social app: readers follow writers, scroll Notes (short posts), comment, and get Recommendations from writers they already read. That network is Substack's growth engine. On its about page, Substack says it has passed 5 million paid subscriptions, that more than half of new subscribers come from its built-in network, and that over 30% of paid subscriptions start inside it. For a setup walkthrough, see how to use Substack.
What is a blog?
A blog is a section of a website where you publish articles, usually listed newest first and organized by category. It can run on WordPress, Ghost, Webflow, Wix, Blogger or a hosted service, and ideally sits on your own domain (yourbrand.com/blog or blog.yourbrand.com).
A blog doesn't send anything by itself. Readers arrive from Google, AI assistants, social links and other sites, and you add an email sign-up form if you want to reach them again. Blog posts are what those assistants cite most: when we asked four AI assistants 96 questions, 74% of the 2,671 sources they cited were blog content. What a blog does better than anything else is accumulate: each article is another page that can rank for searches, and the domain gets stronger as pages earn links.
Substack vs blog: side by side
| Substack | Blog on your own domain | |
|---|---|---|
| How readers find you | Their inbox, the Substack app, Recommendations | Google, AI answers, links, social |
| How fast | Immediate, from day one | Slow: months before search traffic builds |
| Where posts live | yourname.substack.com, or a www subdomain for $50 | yourbrand.com/blog or blog.yourbrand.com |
| Cost to start | Free | Free to a few dollars a month, depending on the platform |
| How you earn | Paid subscriptions, Substack keeps 10% | Ads, affiliate links, products, services, leads |
| SEO control | Basic; sitemaps and Search Console only come as you grow | Full: titles, URLs, redirects, structured data |
| Design | Substack's layouts | Any theme or design |
| Built in | Needs a sign-up form and an email tool | |
| Best for | Writers selling a newsletter | Businesses and creators who want search traffic |
Discovery: inbox and network vs Google
Substack gives you reach on day one. Your first post lands in every subscriber's inbox, and the app can put you in front of people who already pay for similar newsletters. That's why a writer with an audience on social media can build a paid newsletter in months.
A blog earns reach over time. Google needs to crawl, index and test new pages before they rank. In Outrank's Search Console study of 2,119 sites that started publishing with Outrank, the median site gained 7% more clicks in its first 28 days, 27% after 84 days and reached 2.0× its starting clicks by month 7: three slow months, then it compounds (study).
The pages that win are specific. Across the 200,871 articles Outrank wrote in the 90 days to October 2026, the median target keyword had just 170 searches a month and 97% targeted fewer than 1,000 (Outrank platform data). A blog grows by answering hundreds of small, precise questions; a newsletter grows by being worth opening every week.
Substack posts can rank on Google too, mostly for your name and publication title. Substack's own help center says sitemaps and Search Console verification "become available as your publication grows" (source), and without a custom domain every link you earn strengthens substack.com rather than your site.
Money: subscriptions vs everything else
Substack monetizes one way: readers pay you for the newsletter. It's direct and needs no traffic beyond your list, but Substack keeps 10% and Stripe takes about 3.6% plus $0.30 per payment. Our guide to Substack subscription prices shows what popular newsletters charge and what writers keep.
A blog monetizes the attention it gets from strangers: display ads, affiliate links, your own products and courses, sponsored posts, or leads for a service business. None of these pays a platform cut, but each needs traffic, which is why the search engine side matters so much. For the full menu, see how to make money with a blog.
The two models fit different people. An analyst with 20,000 followers can charge them directly on Substack next month. A plumbing company or SaaS product will never sell a newsletter subscription, but a blog post that ranks for the right question can bring customers every week.
Ownership: what you keep if you leave
Both let you leave with your work. Substack exports your posts, subscriber list and stats from Settings → Exports, and paid subscribers pay through your own Stripe account. Two catches: readers who subscribed through the Substack iPhone app pay Apple, and Apple doesn't transfer those subscriptions to another platform; and your Substack URLs (/p/post-name) stay behind unless you used a custom domain and set up redirects.
A blog on your own domain keeps its URLs, links and rankings when you change platforms, as long as you redirect old addresses. That's the core argument for a blog: the asset is the domain, and you own it.

Substack, a blog, or both?
Question 1 of 4
What's the main goal?
Substack vs Blogger, WordPress and Revue
Substack vs Blogger. Blogger is Google's free blogging service: free hosting, a free custom domain (you pay only for the domain) and built-in AdSense. It has had no built-in email subscriptions since FeedBurner stopped sending emails in 2021. Substack is the opposite trade: email and payments built in, little control over the site. Choose Blogger for a free, search-focused hobby blog; choose Substack for a newsletter.
Substack vs WordPress. WordPress is the most common way to run a blog: it powers 39.6% of all websites, according to W3Techs (October 2026). WordPress.com can also send posts to subscribers and sell paid subscriptions, with fees from 10% on the free plan down to 0% on Commerce. We compare costs and fees in detail in Substack vs WordPress.
Revue vs Substack. Revue, the newsletter tool Twitter bought in 2021, was shut down in January 2023, so it's no longer an option. Its users had to move to tools such as Substack, beehiiv, Ghost or Kit.
If you're weighing Substack against Ghost for a paid newsletter, the break-even math is in Ghost vs Substack.
How to run a blog and a newsletter together
The hybrid works when each channel does one job:
- The blog holds evergreen pages. Guides, comparisons, how-tos and tools that answer searches. Publish the full article there, on your domain.
- The newsletter holds the relationship. A weekly email with your take, news, and links to the newest blog posts. Don't paste full articles into both; Google will pick one version to rank, and it may not be the one on your domain.
- The blog feeds the list. Put a sign-up form on every post. If your newsletter is on Substack, Settings → Growth features gives you an embed code that works on most sites.
- Measure each by its own number. Blog: Google clicks in Search Console. Newsletter: subscribers and open rate.
Outrank Blogs is built for the blog half of this setup: free hosting on your own domain or a subfolder like yourbrand.com/blog (free up to 10,000 visits a month), SEO files set up for you, and sign-up forms that send subscribers to your email tool by webhook or CSV. It doesn't send newsletters, so it pairs with Substack or any email tool rather than replacing them. And if writing the evergreen posts is the bottleneck, Outrank researches keywords and publishes an SEO article a day to your blog. Here's how Outrank Blogs compares with Substack.
FAQ
Is Substack a blog?
Partly. Every Substack post is published on a website you can browse like a blog, but Substack is built around the newsletter: posts are emailed to subscribers and discovery happens inside its app. It gives you less control over design, URLs and SEO than a blog on your own domain.
What is the difference between a Substack and a blog?
A Substack delivers each post to subscribers' inboxes and the Substack app, and is built to sell paid subscriptions. A blog lives on a website, ideally your own domain, and gets found through search engines and links. Substack is faster to start; a blog builds a longer-lasting asset.
Is Substack good for SEO?
It's limited. Substack posts can rank, mostly for your name, but sitemaps and Search Console verification only become available as your publication grows, it can't live in a subfolder of your site, and without a $50 custom domain your links build substack.com's authority. A blog on your own domain gives you full control.
Can I use Substack as a blog?
Yes, you can publish posts to the web only and never send them by email. But if you want a blog for search traffic, you give up most SEO controls and your domain's growth, so a dedicated blog platform on your own domain usually serves that goal better.
Can I move my Substack to a blog later?
Yes. Export your posts and subscribers from Substack (Settings → Exports), then import them: WordPress.com has a Substack importer under Tools → Import → Substack, and Ghost has its own migrator. If you used a custom domain, add redirects from the old /p/ URLs.
