Blog SEO Check: Post-Writing Validation
Runs a comprehensive on-page SEO validation against a completed blog post and
generates a pass/fail checklist with specific fixes for each failure. Designed
to run after writing - catches issues before publishing.
Workflow
Step 1: Read Content
Read the target file and extract:
- Frontmatter - title, description, date, lastUpdated, author, tags,
canonical, og:image, slug/URL
- Heading structure - H1, H2, H3 hierarchy with full text
- Links - All internal and external links with anchor text
- Meta tags - OG tags, Twitter Card tags, canonical URL
- Body content - Full text for keyword and structural analysis
If the user provides a URL instead of a file path, use WebFetch to retrieve
the page and extract the relevant elements.
Step 2: Title Tag Validation
| Check | Pass Criteria |
|---|
| Character count | 40-60 characters (no truncation in SERPs) |
| Keyword placement | Primary keyword in first half of title |
| Power word | Contains at least one power word (e.g., Guide, Best, How, Why, Essential, Proven, Complete) |
| Truncation risk | No critical meaning lost if truncated at 60 chars |
| Uniqueness | Not generic - specific to the content |
Step 3: Meta Description
| Check | Pass Criteria |
|---|
| Character count | 150-160 characters |
| Statistic included | Contains at least one specific number or data point |
| Value proposition | Ends with clear reader benefit or value proposition |
| Keyword presence | Primary keyword appears naturally (not stuffed) |
| No keyword stuffing | Keyword appears at most once |
| Call to action | Implies action (learn, discover, find out, see) |
Step 4: Heading Hierarchy
| Check | Pass Criteria |
|---|
| Single H1 | Exactly one H1 tag (the title) |
