--- name: seo-review description: Perform a focused SEO audit on JavaScript concept pages to maximize search visibility, featured snippet optimization, and ranking potential --- # Skill: SEO Audit for Concept Pages Use this skill to perform a focused SEO audit on concept documentation pages for the 33 JavaScript Concepts project. The goal is to maximize search visibility for JavaScript developers. ## When to Use - Before publishing a new concept page - When optimizing underperforming pages - Periodic content audits - After major content updates - When targeting new keywords ## Goal Each concept page should rank for searches like: - "what is [concept] in JavaScript" - "how does [concept] work in JavaScript" - "[concept] JavaScript explained" - "[concept] JavaScript tutorial" - "[concept] JavaScript example" --- ## SEO Audit Methodology Follow these five steps for a complete SEO audit. ### Step 1: Identify Target Keywords Before auditing, identify the keyword cluster for the concept. #### Keyword Cluster Template | Type | Pattern | Example (Closures) | |------|---------|-------------------| | **Primary** | [concept] JavaScript | closures JavaScript | | **What is** | what is [concept] in JavaScript | what is a closure in JavaScript | | **How does** | how does [concept] work | how do closures work | | **How to** | how to use/create [concept] | how to use closures | | **Why** | why use [concept] | why use closures JavaScript | | **Examples** | [concept] examples | closure examples JavaScript | | **vs** | [concept] vs [related] | closures vs scope | | **Interview** | [concept] interview questions | closure interview questions | ### Step 2: On-Page SEO Audit Check all on-page SEO elements systematically. ### Step 3: Featured Snippet Optimization Verify content is structured to win featured snippets. ### Step 4: Internal Linking Audit Check the internal link structure. ### Step 5: Generate Report Document findings using the report template. --- ##

A **closure** is a function that retains access to variables from its outer (enclosing) scope, even after that outer function has finished executing. Closures are created every time a function is created in JavaScript, allowing inner functions to "remember" and access their lexical environment. ``` (This is 52 words - perfect for a featured snippet) --- ### Internal Linking Checklist (4 points) | # | Check | Points | How to Verify | |---|-------|--------|---------------| | 1 | 3-5 related concepts linked in body | 1 | Count `/concepts/` links in prose | | 2 | Descriptive anchor text | 1 | No "click here", "here", "this" | | 3 | Prerequisites in Warning box | 1 | `` with links at start | | 4 | Related Concepts section has 4 cards | 1 | `` at end with 4 Cards | **Good Anchor Text:** | ❌ Bad | ✓ Good | |--------|--------| | "click here" | "event loop concept" | | "here" | "JavaScript closures" | | "this article" | "our Promises guide" | | "read more" | "understanding the call stack" | **Link Placement Strategy:** ```markdown **Prerequisite:** This guide assumes you understand [Promises](/concepts/promises) and the [Event Loop](/concepts/event-loop). Read those first if needed. When the callback finishes, it's added to the task queue — managed by the [event loop](/concepts/event-loop). async/await is built on top of Promises ``` --- ### Technical SEO Checklist (3 points) | # | Check | Points | How to Verify | |---|-------|--------|---------------| | 1 | Single H1 per page | 1 | Only one `#` heading (the title) | | 2 | URL slug contains keyword | 1 | `/concepts/closures` not `/concepts/topic-1` | | 3 | No orphan pages | 1 | Page is linked from at least one other page | **H1 Rule:** Every page should have exactly ONE H1 (your main title). This is critical for SEO: - The H1 tells Google what the page is about - Multiple H1s confuse search engines about page hierarchy - All other headings should be H2 (`##`) and below - The H1 should contain your primary keyword ```markdown # Closures in JavaScript ← This is your H1 (only one!) ## What is a Closure? ← H2 for sections ### Lexical Scope ← H3 for subsections ## How Closures Work ← Another H2 ``` **URL/Slug Best Practices:** | ✅ Good | ❌ Bad | |---------|--------| | `/concepts/closures` | `/concepts/c1` | | `/concepts/event-loop` | `/concepts/topic-7` | | `/concepts/type-coercion` | `/concepts/abc123` | | `/concepts/async-await` | `/concepts/async_await` | Rules for slugs: - **Include primary keyword** — The concept name should be in the URL - **Use hyphens, not underscores** — `event-loop` not `event_loop` - **Keep slugs short and readable** — Under 50 characters - **No UUIDs, database IDs, or random strings** - **Lowercase only** — `/concepts/Event-Loop` should be `/concepts/event-loop` **Orphan Page Detection:** An orphan page has no internal links pointing to it from other pages. This hurts SEO because: - Google may not discover or crawl it frequently - It signals the page isn't important to your site structure - Users can't navigate to it naturally - Link equity doesn't flow to the page **How to check for orphan pages:** 1. Search the codebase for links to this concept: `grep -r "/concepts/[slug]" docs/` 2. Verify it appears in at least one other concept's "Related Concepts" section 3. Check that pages listing it as a prerequisite link back appropriately 4. Ensure it's included in the navigation (`docs.json`) **Fixing orphan pages:** - Add the concept to related pages' "Related Concepts" CardGroup - Link to it naturally in body content of related concepts - Ensure bidirectional linking (if A links to B, B should link back to A where relevant) --- ## Scoring System ### Total Points Available: 30 | Category | Max Points | |----------|------------| | Title Tag | 4 | | Meta Description | 4 | | Keyword Placement | 5 | | Content Structure | 6 | | Featured Snippets | 4 | | Internal Linking | 4 | | Technical SEO | 3 | | **Total** | **30** | ### Score Interpretation | Score | Percentage | Status | Action | |-------|------------|--------|--------| | 27-30 | 90-100% | ✅ Excellent | Ready to publish | | 23-26 | 75-89% | ⚠️ Good | Minor optimizations needed | | 17-22 | 55-74% | ⚠️ Fair | Several improvements needed | | 0-16 | <55% | ❌ Poor | Significant work required | --- ## Common SEO Issues and Fixes ### Title Tag Issues | Issue | Current | Fix | |-------|---------|-----| | Too short (<50 chars) | "Closures" (8) | "Closures: How Functions Remember Their Scope in JavaScript" (58) | | Too long (>60 chars) | "Understanding JavaScript Closures and How They Work with Examples" (66) | "Closures: How Functions Remember Their Scope in JavaScript" (58) | | Missing keyword | "Understanding Scope" | Add concept name: "Closures: Understanding Scope in JavaScript" | | No hook | "JavaScript Closures" | Add benefit: "Closures: How Functions Remember Their Scope in JavaScript" | | Missing "JavaScript" | "Closures Explained" | Add at end: "Closures Explained in JavaScript" | ### Meta Description Issues | Issue | Current | Fix | |-------|---------|-----| | Too short (<120 chars) | "Learn about closures" (20) | Expand with specifics to 150-160 chars | | Too long (>160 chars) | [Gets truncated] | Edit ruthlessly, keep key information | | Starts with "Master" | "Master JavaScript closures..." | "Learn JavaScript closures..." | | No keyword | "Functions that remember" | Include "closures" and "JavaScript" | | Too vague | "A guide to closures" | List specific topics: "Covers X, Y, and Z" | ### Content Structure Issues | Issue | Fix | |-------|-----| | No question hook | Start with "How does...?" or "Why...?" | | Code example too late | Move simple example to first 200 words | | Missing Info box | Add `` with "What you'll learn" | | Long paragraphs | Break into 2-4 sentence chunks | | Under 1,500 words | Add more depth, examples, edge cases | | No bolded terms | Bold key concepts on first mention | ### Featured Snippet Issues | Issue | Fix | |-------|-----| | No "What is" definition | Add 40-60 word definition paragraph | | Definition too long | Tighten to 40-60 words | | No question H2s | Add "What is X?" or "How does X work?"

Every optimization should also improve the reader experience.
