- Assets from cdn2.hubspot.net or js.hs-scripts.com
- A hs-analytics or __hstc cookie set on first load
- hsforms.net embeds for any form on the page
- URLs under /hs-fs/ for hosted files
What HubSpot CMS means for SEO
- The tracking script plus embedded forms is the main script cost; defer everything that is not needed for first paint.
- HubSpot blog listing pages paginate with /page/N URLs that need consistent internal linking to stay crawlable.
- Domain-level canonicalisation is a setting, not a default — check that the primary domain is enforced.
- Template-level meta description defaults are common and produce duplicate descriptions across dozens of pages.
- Landing pages created for campaigns are indexable by default and are the usual source of thin duplicate content.
