Detailed verification steps, PASS/FAIL/WARN criteria, and fix guidance for all 15 on-page and content SEO checks (O1-O8 and C1-C7). For each check: what to look
This skill provides a detailed audit checklist for on-page and content SEO covering 15 critical checks, including unique title tags, meta descriptions, heading structure, image alt text, and internal linking. Each check outlines specific verification steps, clear PASS/FAIL/WARN criteria based on measurable thresholds, and actionable fix guidance tailored to common content and technical SEO issues. The checklist helps ensure pages meet best practices for search visibility, user experience, and crawl efficiency.
The skill emphasizes concrete audit methods using tools like Screaming Frog and Google Search Console, with precise metrics such as title tag length (50-60 characters), meta description length (120-160 characters), and alt text presence. It also guides practitioners on common content structure issues like heading hierarchy and keyword placement to improve both SEO relevance and conversion potential.
This skill is designed for SEO specialists performing technical and content audits, growth marketers aiming to improve organic search performance, and agency strategists managing client site optimization projects. It fits operators who need a comprehensive, repeatable framework for evaluating on-page SEO health across large websites or portfolios.
It is especially useful for teams balancing SEO with content marketing or CRO, where clear audit criteria and fix instructions help prioritize improvements and communicate findings to developers or editors. Performance marketers running iterative tests on metadata and page structure will also benefit from the explicit PASS/FAIL standards to track progress.
A practitioner begins by exporting site data through tools like Screaming Frog to review title tags, meta descriptions, headings, and images against the checklist’s criteria. Next, they classify each page or element with PASS, WARN, or FAIL statuses based on thresholds such as missing tags or duplicate content.
The third step is diagnosing issues flagged as FAIL or WARN, referencing the skill’s fix guidance—for example, implementing unique title templates or restructuring heading hierarchies. Finally, the marketer prioritizes remediation based on page importance and impact, coordinating with content creators or developers to implement fixes and then re-auditing to confirm compliance.
Throughout, the audit integrates manual spot checks and automated filters to ensure accuracy and context-aware decisions, such as avoiding keyword stuffing and ensuring alt text relevance.
How strict should I be with title tag length? Aim to keep titles between 50-60 characters to avoid SERP truncation while maximizing keyword prominence.
Can meta descriptions be duplicated across pages? No, unique meta descriptions with clear value propositions reduce risk of search engines rewriting snippets and improve click-through rates.
What if my CMS doesn’t support heading hierarchy control? Use CSS to style headings visually while maintaining semantic HTML structure, and audit for skipped heading levels to maintain accessibility and SEO.
Attach this skill to a Metaflow agent task when conducting on-page SEO audits or content reviews, especially when verifying metadata and structural SEO elements across many URLs. The agent will guide you through each of the 15 checks with concrete criteria and remediation steps, helping systematize audit workflows and decision-making. You can expect clear PASS/FAIL/WARN results for each check, supporting prioritization and reporting. This skill integrates smoothly with other SEO and content skills in Metaflow for a comprehensive optimization process.
