Squarespace

Squarespace's blog editor needs a Code Block to render raw HTML.

Steps

From your Squarespace dashboard go to Pages → Blog → +.
Add a Code block where the body should be.
Toggle off Display Source. Paste the body HTML.
Save. Add the title in the post header.
Open Post settings → SEO and paste the meta description.
Publish.
Copy the live URL and paste it back into the submit page.
