Host HubSpot Content on WordPress

I need our existing HubSpot blog and a set of HubSpot landing pages moved from their current subdomain so they publish under our primary root domain, www.degrandson.com. The WordPress site (hosted on SiteGround and delivered through Cloudflare) must remain exactly as it is today—our product pages are critical and cannot be disrupted.

Key points you should know
• Both the blog posts and the landing pages must keep their present HubSpot design, layout, and embedded functionality. No visual or structural changes are required; simply serve them from the root domain.
• Only these two asset types—blog posts and landing pages—need to move. HubSpot forms, email templates, or other assets stay where they are for now.
• SEO equity, existing URLs, and analytics tracking have to be preserved. Any redirects or rewrite rules should be handled cleanly to avoid traffic or ranking loss.
• The solution must be fully compatible with SiteGround hosting and our Cloudflare configuration.

Deliverables
1. Seamless routing that lets HubSpot-hosted blog posts resolve under www.degrandson.com/blog/…
2. Equivalent routing for the selected landing pages (e.g., www.degrandson.com/landing/…)
3. Verification that design, scripts, and conversion tracking behave exactly as on the current subdomain.
4. A short hand-off document outlining the DNS, Cloudflare, or WordPress changes you made so we can maintain the setup internally.

If you have handled WordPress ↔ HubSpot integrations before—whether via HubSpot CMS hub settings, reverse proxy, or a Cloudflare-based approach—your experience will be invaluable.
