How to Share Notion on a Custom Domain (None Track Viewers) in 2026

Last updated: March 2026

I run Peony, a data room platform, and our entire internal knowledge base lives in Notion. Team docs, product specs, meeting notes, content drafts -- it all starts there. So when I needed to share Notion pages externally on our own domain, I tested every method available.

The short version: Notion now supports custom domains natively through Notion Sites, and it works well for public content. But the moment you need access controls, viewer analytics, or any kind of security layer, you hit a wall. I ended up using different tools for different audiences -- and that distinction matters more than most guides acknowledge.

TL;DR: Notion Sites supports custom domains ($10/month add-on) for public pages, but offers zero access controls or analytics. Forbes reports that 71% of businesses have a website, yet Verizon's 2025 DBIR found that ~60% of breaches involve a human element like sharing links without access controls, and IBM's 2025 report puts the average credential-related breach at $4.67 million. For public content, Notion Sites or Super.so work great. For anything confidential, Peony adds identity-bound access, page-level analytics, dynamic watermarks, and NDA gates -- set up in under 5 minutes.

What "sharing Notion pages with a custom domain" actually means

When someone searches for this, they usually want one of two things:

1. Public website from Notion -- serve a portfolio, changelog, documentation site, or marketing page at docs.yourcompany.com instead of a notion.site URL
2. Branded external sharing -- send investor updates, client proposals, or confidential docs from your own domain with professional presentation and access control

These are fundamentally different problems, and they need different tools. A public blog and a confidential investor data room have nothing in common except that the content might start in Notion.

Custom domain in this context means connecting your own registered domain (or subdomain like docs.yourcompany.com) to a service that renders your Notion content, so visitors see your brand -- not Notion's -- in the URL bar. It adds credibility, SEO equity, and link stability.

Quick guide: match the method to the use case

Method 1: Notion Sites (native custom domain)

Notion's first-party solution, launched in late 2024 and steadily improved since. If your goal is a public-facing website powered by Notion content, this is the cleanest path.

How to set it up

1. Publish your page -- Open the Notion page you want to share, click Share, then toggle on Publish. Choose your page settings (allow search indexing, show navigation, etc.)
2. Go to Settings -- Navigate to Settings & Members then Sites then Domains
3. Add your domain -- Click Add Domain and enter your domain or subdomain (e.g., docs.yourcompany.com)
4. Configure DNS -- Notion provides a CNAME record. Add it to your DNS provider (Cloudflare, Namecheap, GoDaddy, Route 53, etc.). Point the CNAME to the value Notion gives you
5. Verify and assign -- Once DNS propagates (a few minutes to 48 hours), verify the domain in Notion. Then assign your published pages to it
6. Configure SEO -- Set page titles, descriptions, and social preview images for each published page

Notion's documentation on custom domains walks through the full DNS setup with screenshots for common providers.

What you get

• Your Notion content at yourdomain.com or any subdomain
• Automatic SSL certificates
• Basic SEO fields (title, description, social image)
• Navigation from your Notion page structure
• Up to 25 custom domains per workspace
• Content updates whenever you edit in Notion

What you do not get

• No per-viewer analytics -- you cannot see who visited or what they read
• No access controls -- every published page is fully public
• No password protection -- anyone with the URL sees everything
• No watermarking -- content can be copied or screenshotted with zero attribution
• No link revocation -- you can unpublish the entire page but cannot cut off individual viewers

Cost

$10/month per custom domain, on top of your Notion plan (Plus at $10/user/month or higher). Multiple subdomains count as separate domains.

Best for

Public-facing content: company wikis, changelogs, documentation, portfolios, marketing pages, personal blogs. Anything where you want the world to see it.

Method 2: Third-party Notion website builders (Super.so, Potion, etc.)

If Notion Sites doesn't give you enough design control, performance, or features, several third-party tools take your Notion content and render it as a polished website on your domain -- with more customization options.

Popular options

How it works (using Super.so as an example)

1. Create a Super.so account and connect your Notion page
2. Add your custom domain in Super's dashboard
3. Configure DNS -- Super provides the records (usually an A record or CNAME)
4. Customize styling: themes, fonts, colors, custom CSS, navigation
5. Toggle password protection if needed (Plus plan and above)
6. Publish -- edits you make in Notion sync automatically

Advantages over Notion Sites

• Better performance -- dedicated CDN, faster page loads
• Custom styling -- CSS overrides, themes, custom fonts
• Site-wide password protection -- a gate visitors must pass before seeing content
• Richer analytics -- page view tracking, some tools integrate Google Analytics
• More SEO control -- canonical URLs, sitemap generation, meta tags

Limitations

Password protection is a shared password -- everyone enters the same one. No per-viewer identification. No watermarking. No screenshot protection. No individual access revocation. If the password leaks, you change it and re-distribute.

Best for

Public or semi-public content where you want more design polish than Notion Sites offers: marketing sites, documentation hubs, course landing pages, community resources. A step up in presentation, but still fundamentally public-facing.

Method 3: Notion's built-in "Share to web" with custom branding

The zero-cost option. No custom domain, but you can brand and style the page within Notion itself.

How to set it up

1. Open your Notion page and click Share
2. Toggle Publish (previously "Share to web")
3. Choose settings: allow search engine indexing, allow duplication, show page comments
4. Your page is now live at a notion.site URL
5. Customize the page with a cover image, icon, and structured layout for a branded feel

What you get

• Free (included with any Notion plan)
• Instant publishing
• Notion's clean reading experience
• Automatic updates when you edit
• Option to allow or block search indexing

What you do not get

• No custom domain -- the URL is always yourtitle.notion.site or similar
• No access controls -- anyone with the link sees everything
• No analytics -- no idea who visits or what they read
• No password gate -- fully public
• No branding beyond the page content itself -- Notion's chrome is visible

Cost

Free.

Best for

Quick sharing where the audience is not security-sensitive: internal team announcements shared externally, public resources, event pages, personal projects. Not appropriate for anything where you need to control access or track engagement.

Method 4: Peony (branded data rooms with security and analytics)

If you just need a public-facing website from Notion, use Methods 1-3 -- they are built for that. Peony is for when the content is confidential and you need to control who sees it.

Here is the honest distinction: Notion Sites and Super.so turn your Notion content into a website. Peony turns it into a secure, trackable data room. Different tools for different jobs.

When Notion's sharing breaks down

I saw this firsthand last year. A founder shared her Series A financial model via a published Notion page with a "please don't share" note at the top. Two weeks later, a competitor referenced her gross margins in a pitch to the same investors. She had no way to know who forwarded it, when, or to whom. The link was public. There was no audit trail.

That experience crystallized something: the gap between "published Notion page" and "controlled external sharing" is a security chasm, not a feature gap.

What Peony adds

Upload your documents (export from Notion as PDF, or upload directly) and share via branded links with:

• Identity-bound access -- each recipient gets a unique link with email verification. No shared passwords
• NDA gates -- require a signed agreement before any content is visible
• Password protection -- add a password layer on top of identity verification
• Page-level analytics -- see exactly who viewed which page for how long. Not just "opened" -- which specific sections they spent time on

• Dynamic watermarks -- viewer's email and timestamp baked into every rendered frame. Screenshots become attributable
• Screenshot protection -- blocks and logs capture attempts
• Access revocation -- cut off any individual viewer in one click without affecting anyone else
• AI auto-indexing -- upload a stack of documents and Peony's AI organizes them into a clean folder structure in under 3 minutes
• AI document extraction -- ask natural-language questions across every document and get cited answers with exact page numbers
• Smart Q&A workflow -- counterparties submit questions, AI drafts answers, your team reviews and approves before sending. Full audit trail

How to set it up

1. Sign up for Peony (free tier available)
2. Create a data room -- name it by context (e.g., "Series A Materials" or "Client Proposal -- Acme Corp")
3. Upload your Notion exports (PDFs, decks, docs) or connect directly
4. AI auto-indexes your documents into a standard folder structure
5. Set access controls: specific email addresses, domain whitelists, NDA requirements
6. Enable watermarking, screenshot protection, and link expiry
7. Share the branded link -- each recipient gets their own tracked access

Setup genuinely takes under 5 minutes. I timed it.

Cost

For comparison, traditional VDRs like Datasite charge $1,000+/month and most Notion site builders cost $10-20/month without any security features.

Best for

Investor updates, fundraising data rooms, client proposals, M&A due diligence, legal documents, board materials -- anything where you need to know who saw what and control access after sharing. Popular with startups and venture capital firms where secure file sharing is non-negotiable.

Comparison: all four methods side by side

By the numbers

These stats explain why the custom domain question is really a security and branding question:

• 71% of businesses have a website, making branded domains a baseline expectation (Forbes, 2024)
• ~60% of breaches involve a human element like misshared links or social engineering (Verizon 2025 DBIR)
• $4.88 million is the average cost of a data breach globally (IBM Cost of a Data Breach, 2024)
• 100 million+ users on Notion globally, making it one of the most popular productivity tools for startups and teams (Notion)
• $4.67 million — average cost of a breach involving stolen or compromised credentials (IBM 2025)
• 1 in 10 sensitive files is exposed to every employee in the average organization — 157,000 exposed records per company (Varonis 2025)
• $10/month is what Notion charges per custom domain -- comparable to third-party builders, but with fewer features (Notion Pricing)
• Under 5 minutes is the setup time for a Peony data room with AI auto-indexing -- compared to days for legacy VDR platforms (Peony)

Practical tips for sharing Notion content on your domain

Draw a clear line between public and confidential. Public marketing pages, changelogs, and documentation? Notion Sites or Super.so. Investor updates, client proposals, M&A materials, or anything where a leak has consequences? Peony data rooms. Mixing these on the same tool creates gaps.

Plan your URL structure before publishing. Notion Sites uses your page titles as slugs. If you rename a page, the URL changes and old links break. Decide on your navigation hierarchy first, then publish. This saves painful 404 cleanups later.

Set up proper social previews. Whether you use Notion Sites or a third-party builder, configure title tags, meta descriptions, and Open Graph images so your links look professional in Slack, email, and social media. First impressions happen in the preview card, not on the page.

Audit published pages quarterly. It is easy to forget what is public. Check your Notion Sites dashboard and any third-party builder accounts for pages that should no longer be live. For Peony, set automatic link expiry dates when you create the share link.

Do not rely on "please don't share" for sensitive content. If the content matters, use tools with enforcement: identity verification, watermarking, screenshot protection, and revocation. Hope is not a security strategy.

Use Notion as the editing layer, not the sharing layer. For confidential documents, keep your source of truth in Notion for internal collaboration, then export and share through a controlled platform. This way you get Notion's excellent editing experience and Peony's security and analytics for external audiences.

Consider your SEO strategy. Notion Sites and Super.so are indexed by search engines -- great for content marketing, terrible for confidential documents. If your content should not appear in Google, do not publish it on any public Notion tool. Use Peony's private data rooms instead.

Bottom line

In 2026 there are three clean paths, and the right one depends on your audience:

• Public content (blog, docs, portfolio) -- Use Notion Sites ($10/mo) for simplicity or Super.so ($10-12/mo) for more design control. Both serve Notion content on your custom domain with automatic syncing.
• Semi-public content with a simple gate -- Use Super.so or Potion with site-wide password protection. Good enough for course materials, community resources, or internal docs that need a lightweight barrier.
• Confidential external sharing -- Use Peony (free tier available). Identity-bound access, per-viewer page-level analytics, dynamic watermarks, NDA gates, screenshot protection, and instant revocation. This is the tool for investor materials, client proposals, due diligence, and anything where you need to control who sees what.

The important thing is matching the tool to the sensitivity. A public changelog does not need a data room. An investor financial model does not belong on a public Notion page. Get the pairing right and your Notion content works as hard as your domain does.

FAQ

Does Notion support custom domains natively?

Yes. Since late 2024, Notion Sites lets you connect a custom domain to published Notion pages. It requires a paid Notion plan plus a $10/month add-on per domain. You configure a CNAME record in your DNS provider, verify it in Notion, and your pages appear at your domain. The limitation is that Notion Sites is designed for public content only -- there are no per-viewer analytics, no password gating, no watermarking, and no access revocation. For sensitive external sharing, Peony adds identity-bound access with page-level analytics that show exactly who viewed which page and for how long.

What is the cheapest way to put Notion pages on a custom domain?

Notion Sites at $10/month per domain is the cheapest official option. Third-party builders like Potion start at $10/month and Super.so at $12/month with more design control included. If you need a free option, Fruition uses Cloudflare Workers but requires technical setup and ongoing maintenance. For secure external sharing where you also need analytics and access controls, Peony starts free at $0 with data rooms, watermarking, and screenshot protection included -- no custom domain add-on fee required.

Can I share Notion pages on a custom domain with access controls?

Notion Sites does not support access controls on custom domain pages -- everything published is fully public. Third-party builders like Super.so offer site-wide password protection starting at $12/month, but it is a shared password with no per-viewer tracking. For identity-based access on a branded domain, Peony provides email verification, NDA gates, dynamic watermarks, and per-viewer revocation so you control exactly who sees your content and can cut off access instantly.

How do I set up a custom domain for Notion Sites?

Go to Settings and Members, then Sites, then Domains. Click Add Domain and enter your domain or subdomain. Notion will provide a CNAME record to add in your DNS provider (like Cloudflare, Namecheap, or GoDaddy). DNS propagation typically takes a few minutes to 48 hours. Once verified, assign your published Notion pages to the domain. SSL is handled automatically. The process takes about 15 minutes of active work. If you need faster setup with built-in security controls, Peony data rooms are ready to share in under 5 minutes with no DNS configuration required.

What are the limitations of Notion Sites for sharing documents?

Notion Sites has five key limitations for document sharing. No per-viewer analytics (you cannot see who visited or what they read), no password or identity gating (anyone with the URL can access the content), no watermarking (leaked content is untraceable), no screenshot protection (visitors can capture anything freely), and no access revocation (you can only unpublish the entire page, not cut off individual viewers). Peony fills all five gaps with AI-powered auto-indexing that organizes your documents in under 3 minutes and dynamic watermarks that embed viewer identity into every rendered frame.

Should I use Notion Sites or Super.so for my custom domain?

Use Notion Sites if you want the simplest setup and your content is straightforward (company wiki, changelog, portfolio). Use Super.so if you need custom CSS, faster page loads, built-in analytics, or site-wide password protection. Both are designed for public-facing content. If your content is confidential -- investor updates, client proposals, legal documents -- neither is appropriate. Peony provides a branded sharing experience with advanced Q&A workflows where counterparties submit questions, AI drafts answers, and your team reviews before sending responses with a full audit trail.

Can I track who views my Notion pages on a custom domain?

Notion Sites provides no viewer analytics at all. Super.so and Potion offer basic page view counts but cannot identify individual viewers. Google Analytics can be added to some Notion site builders for aggregate traffic data. For per-viewer tracking -- seeing that a specific person spent 8 minutes on your pricing page and skipped the legal section -- you need a document sharing platform. Peony provides page-level analytics tied to verified email addresses, so you know exactly who read what and for how long.

How do I share sensitive Notion content externally without making it public?

Do not use Notion Sites or any public Notion site builder for sensitive content. Instead, export your Notion pages as PDFs or connect your workspace to a secure sharing platform. Peony lets you upload documents or connect Notion content, then share via identity-bound links with email verification, NDA gates that require signatures before access, dynamic watermarking with viewer identity baked into every rendered frame, and screenshot protection that blocks and logs capture attempts. You keep editing in Notion while Peony handles secure distribution.
