In an ideal setup, redirecting a subpage (e.g. yourdomain.com/page) to an external website should be done using a 301 redirect. A 301 redirect is a server-side instruction that permanently sends users and search engines to a new URL.
However, in some platforms (like static site builders, CMS layers, or Notion-based sites such as Super-style setups), true server-side 301 redirects for individual subpages are not always supported.
When that’s the case, you can use a JavaScript-based redirect workaround.
Important Limitation
A JavaScript redirect:
Works for users (browser-based redirect)
Is NOT a real 301 redirect
May not pass full SEO authority like a server-side redirect
So while it solves navigation issues, it is not a full replacement for SEO-grade redirects.
Workaround: JavaScript Redirect for Subpages
You can add this script inside the page’s custom code section (header or footer depending on your setup):
<script>
(function () {
// Change this to your destination URL
var targetUrl = "https://external-site.com";
// Optional: small delay (helps avoid flicker in some systems)
setTimeout(function () {
window.location.replace(targetUrl);
}, 100);
})();
</script>
Alternative Version (Instant Redirect)
If you don’t want any delay:
<script>
window.location.replace("https://external-site.com");
</script>
Optional: Path-Based Redirect Logic
If you are applying this across multiple subpages and want conditional redirects:
<script>
(function () {
var path = window.location.pathname;
if (path === "/old-page") {
window.location.replace("https://external-site.com/new-page");
}
if (path === "/another-page") {
window.location.replace("https://external-site.com/another");
}
})();
</script>
