Site health

Site health shows which pages of your site visitors can't open and which pages have SEO warnings, and helps you fix them in a few clicks.

Super builds every page of your site from Notion. When a page can't be built, for example because it was deleted in Notion, visitors get a 404. Site health collects these pages in one place, explains why each one failed and lets you resync, redirect or delete them, one by one or in bulk.

Where to find it

Inside a site: open your site in the Super dashboard and click Site health in the site menu.
For all your sites: click Site health in the main menu. It lists only the sites that have broken pages or SEO warnings in the last 7 days. Open a site to fix them.
On the Sites page: each site card shows a pill: red N issues, amber SEO warnings or green Healthy. Click it to open that site's Site health.

A dot next to Site health in the menu means at least one page needs your attention.

How it works

Super checks a page each time someone opens it, so Site health shows each page's last check. The list covers pages whose last build reported an issue in the last 7 days, newest first, up to 1,000 pages.

The page is split into three tabs:

Needs attention – pages visitors can't open right now (they get a 404).
SEO warnings – pages that work, but search engines may get the wrong address.
Fixed this week – pages that had an issue and no longer do. Each one is labelled Fixed (the last build worked), Redirected (hover to see where to) or Hidden.

On the left of each tab you can filter by issue type and search by page path.

Issue types

Errors (Needs attention)

Issue	What it means	How to fix it
Moved outside the site	The page still exists in Notion, but it's no longer under your site's home page, so Super can't publish it.	Page is outside your site
Removed in Notion	Notion returns no content for the page: it was deleted, moved to trash or unpublished.	Page was removed in Notion
Not a page	The URL points to a Notion block that isn't a page.	URL doesn't point to a Notion page

SEO warnings

Warning	What it means	How to fix it
Canonical set by custom code	A canonical tag in your site or page Head code applies to the page, so Super doesn't add its own or keep it up to date.	How to Use Canonical URLs for SEO
Your site is also live on [name].super.site	Your custom domain is connected, but the default `[name].super.site` address still serves the same pages.	Your Site Is Live on Both [name].super.site and Your Custom Domain

Fixing pages

Open a page's menu (⋯) in the list, or select several pages and use the bar above the list:

Resync – fixed something in Notion? Resync the pages and Super checks them again in the next few minutes. You can resync up to 10,000 pages every 4 hours on Pro and 1,000 pages every 12 hours on Personal and Lite.
Redirect – send visitors from a broken page to another page or URL. Available on Personal and Pro. See Beginner's Guide to Page Redirects in Super (301, 302, and 404).
Delete – remove the page from your Super site. This doesn't change anything in Notion. Deleting a page also removes all pages under its path; if some of them still work, Super lists them and asks you to confirm.
Open in Notion / open on site – check the page where it lives.

Select all selects every page that matches the current tab, filter and search.

Want changes checked right away instead of the next time someone opens the page? Install Instant sync (the Super Sync Chrome extension) from the Instant sync page in the dashboard.

Lots of pages to fix?

We can export the list for you or resync every page – click Chat with us in Site health. You can also fix pages in bulk with an AI assistant through the MCP (AI).

Free sites

Free sites see how many issues the site has in each tab and issue type, but the list of affected pages is locked. Upgrade the site to see which pages have issues and fix them from Site health.

FAQ

A page I fixed still shows up. Site health shows each page's last check. Resync the page, or wait until someone opens it. Once the next build works, it moves to Fixed this week.

I see a 404 in the list for a URL I never created. Site health lists only pages that are on your site's Pages list, so the page was added to Super at some point (often automatically by page sync). If you don't need it, delete it.

Why only the last 7 days? Site health counts pages whose last check was in the last 7 days. A page that nobody opened for longer isn't counted, but it still gets its error label on the Pages list.
