HubSpot CMS SEO Audit — Beyond the Marketing Hub Score
HubSpot-aware audit reads what your live site ships, not what the SEO panel claims.
HubSpot's CMS Hub bundles SEO recommendations into the editor, which is helpful for catching the basics. What it doesn't show you is the schema your modules actually emit, the page weight your forms and tracking scripts add, or whether your AI bot access is configured correctly. SEOGrade audits your live HubSpot site and tells you what the in-editor SEO panel doesn't cover.
Common SEO issues on HubSpot sites
HubSpot tracking scripts and form embeds inflating page weight
Every HubSpot page ships hs-scripts.com, embed.js, and analytics-2.js — totaling 200KB+ before your own assets. INP suffers especially on form-heavy pages.
Module-emitted schema is incomplete
HubSpot's blog module emits BlogPosting schema but commonly skips author Person details, dateModified, and image. Pricing modules don't emit Product schema at all.
Author bylines linked to /author/[name] thin pages
Auto-generated author pages have no bio, no photo, no description — pure thin content. They get indexed by default and dilute author-credibility signals.
Smart Content variants creating crawler confusion
Smart Rules show different content based on lifecycle stage. Crawlers see one variant; logged-in users see another. Without canonical management, this fragments indexing.
Custom modules without alt text on image fields
Custom modules let designers add image fields but don't enforce alt text. Common to ship pages where 30%+ of images have empty alt attributes.
How to fix them
Defer non-critical HubSpot scripts
In Settings → Website → Pages → System Pages, defer or async-load the HubSpot tracking script. Lazy-load forms below the fold using intersection observer.
Override blog module to emit complete BlogPosting schema
Clone the default blog post template, edit the JSON-LD module to include full Person author, dateModified, image dimensions. We provide the exact HubL snippet.
Set author archive pages to noindex
If you have multiple authors, write real bios. If you don't, noindex /author/* via robots.txt or add <meta name='robots' content='noindex,follow'> in the author template.
Set canonical on Smart Content variants
All Smart Content variants on the same URL should share canonical = the URL itself. If variants live on different URLs, use canonical to point to the primary.
Enforce alt text on all module image fields
When building or editing custom modules, set image fields as required and enforce alt-text via custom validation. Audit existing pages and backfill missing alt text.
