seo-content-audit — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited seo-content-audit (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
A page can pass every structural check, load fast, validate every schema, and still rank nowhere — because the content doesn't match search intent, the headings bury the answer, the byline says "Admin," or the top 10 already covers everything this page says. This skill diagnoses the on-page layer that the structural audit can't see: how the content is shaped against the SERP it wants to win.
The audit cross-references the target page against the actual SERP — top 10 results, AI Overview presence, "People Also Ask" coverage, voice-search phrasing — and returns findings where the page falls short of what's already winning. Information-gain (what does this page add that the top 10 doesn't) is the 2026 ranking gate; an information-gain-zero page is now actively suppressed as AI-derivable filler.
On-page content audit is intent-versus-execution:
The audit is not "compare to a checklist." It's "compare to the SERP." Generic on-page advice (keyword in title, keyword in H1) is necessary but not sufficient in 2026. Sufficient is matching the format, depth, and experience signal of the pages that already rank.
webfetch the target URL — capture title, meta, headings, body, byline, any visible schema-rendered elements.websearch the target keyword — capture top 10 organic, AIO presence, "People Also Ask", "Related searches", featured snippet holder.webfetch 3–5 top-ranking pages from the SERP — for direct comparison.websearch "[target keyword] site:reddit.com" — capture community discussion (load-bearing for AI citation in 2026).Run all four in one block. Don't serialize.
| # | Check | How to verify | Severity if failed |
|---|---|---|---|
| 1 | Intent match | Read the target keyword aloud — what does the searcher want? Compare to page intent. | Critical if format mismatches dominant SERP intent |
| 2 | Title tag | 50–60 chars, primary keyword front-loaded, compelling (clear value, not generic) | Moderate per failed dimension |
| 3 | Meta description | 150–160 chars, keyword present, answers "why click this result" | Moderate per failed dimension |
| 4 | H1 | Present, unique, semantically related to title (not identical), describes the page's promise | Critical if missing or duplicate |
| 5 | H2 structure | Voice-search phrasing where natural ("What is X?", "How to Y", "Why Z") — voice/AI assistants match conversational queries | Moderate if all headings are noun-phrase labels |
| 6 | Answer-first per section | 40–50 word direct answer immediately after each H2, before longer body | Moderate per H2 that buries the answer |
| 7 | Extractable passages | Each major point is a self-contained ~150-word unit that works as a standalone answer | Moderate if key answers require reading multiple paragraphs to reconstruct |
| 8 | Data density | At least one concrete number, percentage, or statistic per major section | Minor per data-free section; Moderate if entire piece lacks specifics |
| 9 | FAQ section | Present and recommended for the intent class (informational and commercial benefit most; 2.8x AI-citation lift with FAQ schema) | Minor if absent and intent is suitable |
| 10 | Author byline | Real name + role + credentials + outbound link (LinkedIn / publication / org bio). "Admin" or anonymous = Critical | Critical if anonymous or generic-name attribution |
| 11 | Experience proof | Original screenshots / dashboards / photos from the field / named tools+versions / time-boxed case-study language | Critical if pure explainer with no experience signal on YMYL or expertise-required topic |
| 12 | Information gain vs top 10 | Identify the specific thing this page adds (original data, contrarian take, novel synthesis, practitioner detail) that the top 10 doesn't | Critical if the page is reconstructable from the top 10 (information-gain-zero) |
| 13 | Internal linking | 5–10 contextual links per piece; descriptive anchors (not exact-match); pillar/cluster pattern present where applicable | Moderate if under 3 internal links or all anchor text is generic |
| 14 | Schema readiness for content | Article schema present with author/datePublished/dateModified; FAQ schema if FAQ section exists; HowTo if procedural | Moderate per missing schema on eligible content |
| 15 | Primary-source posture | Page presents primary data/experience/original synthesis OR cites primary sources where it relies on them | Critical if the page is an intermediary roundup of other rankers without added signal (March 2026 update demoted intermediary pages — 80% of top-3 shifted) |
Information-gain is the most ranking-relevant 2026 signal — when in doubt, weight it Critical.
Before scoring, fetch and skim 3–5 top-ranking pages. Identify everything the SERP already says. Then score the target on:
If you cannot name what the target page adds that the top 10 doesn't, that is the finding: "Information-gain-zero — page reconstructable from current top 10. Highest-priority fix."
Voice and AI assistants match conversational queries verbatim. H2s should sound like the spoken query, not the SEO-token version:
When auditing H2s, count the number phrased as spoken queries vs noun-phrase labels. Flag if fewer than half are conversational.
When auditing a page targeting a keyword that triggers AI Overviews:
Never infer information gain from one source; never grade an anonymous byline before checking if there's an author bio page linked.
Use the canonical output structure from the agent that runs this skill. Every finding includes: severity, evidence (URL section, line, the missing element, the SERP comparison point), why it matters, fix direction. Save as seo-audit-[slug]-[YYYY-MM-DD].md in working directory.
