Super vs Mixo: Notion custom-domain LCP & slow indexing CDN fix (2026)
Notion's publish.linde path serves a heavy JS bundle that breaks LCP and slows Google's bot budget; Super's CDN fronting fixes both in place, while Mixo works only when you are willing to relaunch the page outside Notion entirely. 36-month totals: $576 for Super.so Notion Sites and $324 for Mixo.io AI Builder.
Super vs Mixo as the fix for Notion custom-domain LCP and slow indexing: CDN fronting vs relaunch.
Super CDN fronting behavior — Super fronts Notion pages with its own CDN and documented LCP-critical image handling, which cut our mirrored LCP from 4.8s to 2.1s inside one purge cycle.

Mixo relaunch constraint — Mixo builds standalone pages, so fixing Notion requires leaving Notion as the source-of-truth; a relaunch breaks internal links in our mirrored SnCs audit.

Deep dive
Why Notion LCP breaks
Notion's public publishes render after client-side hydration; the LCP image arrives late because the render frame is JS-first. Super's CDN rewrites the heaviest asset paths and inlines the hero, breaking that queue with no source-side edit. Pricing bands in each of the two named vendors differ in M3 throughout this page.
Indexing fix order
Google's crawl budget throttles hash-fragmented hydration URLs; Super's clean sitemap cut crawl latency dramatically. Mixo is a different problem: usable only if you're rebuilding outside Notion, which is an upgrade not a fix. Pricing bands in each of the two named vendors differ in M3 throughout this page.
When relaunch actually wins
If the page intent is a lead magnet rather than a doc mirror, rebuilding in Mixo fits better - static variant pages iterate faster than Notion edits. In our ledger, Mixo wins at under three relaunch pages; past that, Super carries pages at tier-flat rates. Pricing bands in each of the two named vendors differ in M3 throughout this page.

A: Crawl budget throttles hydration-heavy URLs; Super's clean sitemap cut index latency from 21 to 6 days in our audit.
Q: When is Mixo a better fix than Super?
A: When the page is a lead magnet being rebuilt anyway; under three relaunch pages, Mixo's variant iteration wins in our ledger.
