SEO fields for content

The SEO Title, Meta Description, Canonical URL, and Noindex fields on every content item, and how they are written into the published frontmatter.

ReferenceFor Editors, Authors, and OwnersUpdated June 7, 2026

Every content item has an SEO Details section in the editor for the metadata search engines and social platforms read. Filling it in helps your published pages describe themselves clearly. This page explains each field and how it is written into the published file.

The SEO fields

In the editor, open SEO Details. You will find:

  • SEO Title — the title used for search and sharing. If you leave it empty, Acrosite can fall back to the content title.
  • Meta Description — a short summary of the page. If you leave it empty, the item's excerpt can be used as a placeholder.
  • Canonical URL *(optional)* — the preferred address for this content when the same page can appear at more than one URL.
  • Noindex — a checkbox that records a preference to keep this page out of search engine indexes in the published output.

How the fields are written

When the item publishes, the SEO fields are written into the frontmatter under an seo block:

yaml
seo:
  title: "Welcome to our site"
  meta_description: "A short, accurate summary of the page."
  canonical_url: ""
  noindex: false

Your site's templates read these keys to render the page's <title>, meta description, canonical link, and robots directives. See Generated Markdown and frontmatter for the full file.

Writing good SEO metadata

  • Keep the SEO Title concise and specific — it is what people see in search results.
  • Write a Meta Description that accurately summarises the page in one or two sentences. Do not stuff keywords.
  • Set a Canonical URL only when the same content is reachable from multiple URLs and you want one to be authoritative.
  • Use Noindex for pages you do not want in search, such as thank-you or internal pages.

The Publish Readiness checks in the editor confirm that an SEO Title and Meta Description are filled in or have a usable placeholder before publishing, so you are nudged to complete them.

Frequently asked questions

No. SEO Title and Meta Description can fall back to the content title and excerpt, and Canonical URL is optional. Filling them in gives you precise control, which is worth it for important pages.
Noindex records a preference, written into the published frontmatter, to keep the page out of search engine indexes. Your site templates must read that value and emit the matching robots directive for it to take effect.
Set a canonical URL when the same content can be reached from more than one address. It tells search engines which URL is the authoritative one, avoiding duplicate-content confusion.
