seo-social-cards

Audit and generate Open Graph and Twitter/X social-card tags for a page — check og:title/description/url/type, og:image presence/size/reachability, and twitter:card/title/description/image, then inject complete card tags inferred from the page.

seo-social-cards (M8)

Social cards control how a URL renders when shared on social, chat, and AI assistants — a CTR/sharing signal, not a ranking one (see Honesty). Open Graph metadata is the same <head>-level hygiene tier as the structured-data work in references/schema-tier1.md, so audit it alongside that module.

Inputs

Work from the PageSnapshot named in your dispatch envelope: read parsed from <run_dir>/pages/<slug>.json (metas[] for og:*/twitter:*, canonicals[], images[]); Grep pages/<slug>.html for verbatim evidence; site artifacts live in <run_dir>/site/{robots.json,sitemaps.json,discovery.json}. Deterministic findings already emitted by audit.mjs are listed in <run_dir>/findings.deterministic.json — do not re-emit those ids; add model-judged findings only. If invoked directly with a URL/path and no snapshot exists, first run node "${CLAUDE_PLUGIN_ROOT}/scripts/snapshot.mjs" <target> --out "${CLAUDE_PLUGIN_DATA}/runs" and use the printed snapshot path.

Audits

Working from the PageSnapshot (parsed_rendered when render.used is not none, else parsed):

  1. OG content: og:title, og:description, og:url, og:type present and non-empty; og:url matches the canonical; og:type sane for the page (e.g. article vs website).
  2. OG image: og:image present, ~1200x630 (1.91:1) and >=200x200, and reachable (HTTP 200, image content-type, absolute URL).
  3. Twitter/X: twitter:card (prefer summary_large_image); twitter:title, twitter:description, twitter:image. Twitter falls back to OG when these are absent — note when it is relying on OG.
  4. Fallback behavior: when OG is absent entirely, record what crawlers would derive (<title>, meta description, first content <img>) so the finding shows the actual degraded card, not a guess.

Fixes

  • AUTO (fixable: auto): inject a complete OG + Twitter card block derived from the page's <title>/<h1>, meta description, canonical URL, and first in-content image. Additive, deterministic, emitted as a diff for fix.
  • The tool cannot create an image asset. It wires og:image/twitter:image once a real path exists; until then it leaves a clearly-marked TODO placeholder (no invented URL or dimensions). Never fabricate title/description text — derive from on-page content or leave the user a TODO.

Verification

  • dom_assert: the required <meta property="og:*"> / <meta name="twitter:*"> tags exist and are non-empty.
  • header_check: og:image returns 200 with an image content-type, and dimensions are ~1200x630.
  • When the image fetch or dimension probe is blocked (no network/egress), status is needs_api, never a false pass.

Findings

Emit findings per schema/finding.schema.json. Examples:

  • M8.og.missing_image — no og:image (status fail, severity 2, fixable: auto, axis search, confidence established).
  • M8.og.image_unreachable — og:image set but returns non-200 / wrong type (status fail, severity 2, fixable: proposed, axis search, confidence established).
  • M8.twitter.no_card — no twitter:card, page falls back to OG only (status warn, severity 2, fixable: auto, axis search, confidence directional).

Each finding: evidence.observed quotes the tag(s) (or their absence) on the page; verification.reproduce is a runnable dom_assert/header_check command; expected_impact is banded + confidence-tagged (no naked %).

Honesty

Social cards are a sharing / click-through signal with near-zero direct ranking impact — Google does not use OG tags as a ranking factor. They improve how shared links and AI-assistant previews render, not where the page ranks. Fix them for CTR and brand consistency; do not over-invest expecting SERP movement.
