Meta tags & social sharing

Citera outputs all the standard meta tags every page needs for good SEO and clean social sharing.

What’s emitted on every page

  • Title tag — page title | store name
  • Meta description — short summary, from the page’s description or a fallback
  • Canonical URL — the definitive URL for the page (protects against duplicate content)
  • Open Graph tags — og:title, og:description, og:image, og:type (for Facebook, LinkedIn, Slack, iMessage)
  • Twitter card — twitter:card, twitter:title, etc.
  • Robots directives — from Shopify’s robots.txt

Set the default share image

The image that appears when someone shares any of your pages on Facebook, Slack, LinkedIn, X, iMessage, etc.

Theme settings → Branding

Find Social sharing image

Upload a 1200×630 image. See Logo & brand identity for guidance.

Per-page overrides

To use a different image or description for a specific page:

Shopify admin → Online Store → Pages → [pick page]

Scroll to Search engine listing preview

Click Edit website SEO

Set:

  • Page title — the browser tab title and Google result title
  • Meta description — the snippet under the title in Google results

For a per-page share image, use a Shopify metafield like custom.social_image and reference it in the page template (advanced).

Save

Product page overrides

Product pages auto-generate meta from the product title and description, but you can override:

Shopify admin → Products → [pick product]

Scroll to Search engine listing preview

Click Edit website SEO

Same as pages — override title, description.

Canonical URLs

Canonicals point to the definitive URL for a piece of content, ignoring URL variations (like ?utm_source= tracking params). Citera sets canonicals automatically:

  • Product pages → the base product URL (no query params)
  • Collection pages → the base collection URL (filters and sort don’t create duplicate content because they use query params, and canonicals point to the unfiltered URL)
  • Blog articles → the article’s own URL

Robots directives

Shopify’s robots.txt at your-shop.com/robots.txt controls what crawlers can index. It’s editable via Online Store → Preferences → Search engines in your Shopify admin.

Don’t block AI crawlers. Some stores add Disallow: / for OpenAI’s or Anthropic’s crawler in an attempt to opt out of AI training. This also blocks answer engines from citing you — a net negative for discovery. Leave the AI crawlers enabled.
