This skill treats SEO as an engineering discipline: measurable inputs, observable outputs, and iterative improvement - not guesswork. --- ## When to use this skill Trigger this skill when the user: - Researches keywords or analyzes search intent for content - Writes or audits page titles, meta descriptions, headings, or body copy - Implements structured data (JSON-LD, schema.org) - Configures sitemaps, robots.txt, canonicals, or hreflang - Diagnoses poor rankings, low organic traffic, or crawl coverage gaps - Optimizes Core Web Vitals (LCP, CLS, INP) - Plans a link building or digital PR strategy - Sets up Google Search Console, GA4, or rank tracking Do NOT trigger this skill for: - Paid search / PPC campaigns - budget bidding and ad copy are a separate domain - Social media content strategy where search ranking is not the goal --- ## Key principles 1. **Content quality first** - Google's ranking goal is to surface the most helpful answer for a query. No technical trick compensates for thin, unhelpful content. Write for humans, then ensure machines can understand it. 2. **Technical foundation enables ranking** - A great page that cannot be crawled, indexed, or rendered earns zero organic traffic. Fix crawl/index issues before investing in content. 3. **User intent matches content** - Every query has an intent (informational, navigational, transactional, commercial). Misaligning content type with intent kills rankings no matter how well-optimized the page is. 4. **Build authority, not just links** - Backlinks are votes of trust. Ten links from authoritative, relevant sites outweigh a thousand links from irrelevant or low-quality domains. Pursue earned links through genuine value creation. 5. **Measure and iterate** - Rankings fluctuate. Traffic converts. Use Search Console, GA4, and rank tracking to form hypotheses, ship changes, and measure outcomes over 90-day windows - not days. --- ## Core concepts ### On-page vs off-page vs technical SEO | Pillar | Scope | Examples | |---|---|---| | **On-page** | What is on the page | Title, headings, copy, images, internal links | | **Off-page** | Signals from other sites | Backlinks, brand mentions, digital PR | | **Technical** | How search engines access the page | Crawl budget, indexing, speed, structured data | All three pillars compound. Technical issues block the others from working. ### Crawling, indexing, ranking pipeline ``` Googlebot crawls URL -> Renders JavaScript (Chromium-based) -> Parses content and signals -> Indexes page (adds to search database) -> Ranks against competing pages for relevant queries -> Serves result to user ``` A breakdown at any stage stops organic visibility. Use Search Console's URL Inspection tool to diagnose where in this pipeline a page is stuck. ### Search intent types | Intent | What the user wants | Content match | |---|---|---| | **Informational** | Learn something | Blog posts, guides, how-tos, FAQs | | **Navigational** | Find a specific site/page | Brand pages, login pages | | **Transactional** | Complete a purchase or action | Product pages, checkout, sign-up | | **Commercial** | Research before buying | Comparison pages, reviews, "best X" lists | Mismatching content type to intent is the most common reason well-written pages under-rank. ### E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) Google's quality rater guidelines use E-E-A-T as the quality signal framework. Practical implementations: - **Experience** - first-hand demonstrations: screenshots, case studies, personal results - **Expertise** - author credentials, bylines, depth of coverage - **Authoritativeness** - third-party mentions, links from recognized industry sources - **Trustworthiness** - HTTPS, clear privacy/contact pages, accurate information, citations --- ## Common tasks ### Conduct keyword research Use this framework to identify target keywords before writing any content: ``` 1. Seed keywords - list 5-10 core topics your product/service addresses 2. Expand seeds: - Google Autocomplete and "People Also Ask" for each seed - Google Search Console "Queries" report for existing rankings - Competitor gap analysis (Ahrefs / Semrush / free: Ubersuggest) 3. Evaluate each keyword on three dimensions: - Search volume (how many searches/month) - Keyword difficulty (how competitive, 0-100) - Business relevance (how likely to convert) 4. Classify intent for each keyword (informational / transactional / commercial) 5. Cluster keywords by intent and topic: - One primary keyword per page - 2-5 semantically related secondary keywords per page - Build topic clusters: one pillar page + multiple supporting pages ``` **Priority formula (rough):** score = (volume * relevance) / difficulty Target low-difficulty / high-relevance keywords first to build topical authority before going after high-difficulty head terms. ### Optimize on-page SEO Apply this checklist to every page: **Title tag** - most important on-page signal: ```html Keyword Research Guide: 5-Step Framework (2024) Acme Corp | Our Blog | How We Do Things ``` **Meta description** - not a ranking factor but drives click-through rate: ```html ``` **Heading hierarchy** - one H1 per page, H2 for major sections, H3 for subsections: ```html

Keyword Research: The Complete Guide

What Is Keyword Research?

Step 1: Find Seed Keywords

Using Google Autocomplete

Using Search Console

Step 2: Evaluate Keyword Difficulty

``` **Image optimization:** ```html Comparison chart of keyword research tools: Ahrefs vs Semrush vs Ubersuggest ``` **Internal linking** - link from high-authority pages to target pages using descriptive anchor text (not "click here"): ```html keyword research framework ``` ### Implement schema markup Use JSON-LD injected in `` or before ``. Never use Microdata - JSON-LD is Google's recommended format. **Article schema:** ```html ``` **FAQ schema** (earns rich snippets in SERPs): ```html ``` See `references/schema-markup.md` for Product, BreadcrumbList, HowTo, LocalBusiness, and SitelinksSearchbox schemas. ### Set up technical SEO **sitemap.xml** - submit to Search Console, update on publish: ```xml https://example.com/keyword-research-guide 2024-03-10 monthly 0.8 ``` **robots.txt** - allow all, block crawl-waste paths: ``` User-agent: * Disallow: /admin/ Disallow: /search? Disallow: /cart Allow: / Sitemap: https://example.com/sitemap.xml ``` **Canonical tags** - prevent duplicate content penalties: ```html ``` **Noindex for non-content pages:** ```html ``` Use noindex on: tag pages, filter facets, thank-you pages, staging environments. ### Optimize Core Web Vitals Target thresholds: LCP < 2.5s, CLS < 0.1, INP < 200ms. **LCP (Largest Contentful Paint) - improve render time of main image/text:** ```html ... ``` **CLS (Cumulative Layout Shift) - prevent unexpected layout shifts:** ```html ...
``` **INP (Interaction to Next Paint) - reduce main thread blocking:** - Defer non-critical JavaScript: `` - Break long tasks using `scheduler.yield()` or `setTimeout(..., 0)` - Use `content-visibility: auto` on off-screen sections Measure with: PageSpeed Insights, Chrome DevTools > Performance panel, CrUX dashboard. ### Build a link building strategy Links remain among Google's top three ranking factors. Prioritize these in order: 1. **Digital PR** - create genuinely newsworthy data, research, or tools. Pitch to journalists covering your industry. One Forbes or TechCrunch link > 1000 directory links. 2. **Resource page link building** - find "[topic] + resources" pages in your niche. If your content is better than what they link to, pitch a replacement. 3. **Broken link building** - use Ahrefs/Semrush to find broken links on authoritative sites. Offer your content as a replacement. 4. **Guest posts** - write high-value articles for reputable industry blogs with a contextual link back. Avoid link farms and PBNs - manual penalties are severe. 5. **Unlinked mentions** - set up Google Alerts for brand name. When mentioned without a link, request one from the author. **Evaluate link quality before pursuing:** - Domain Rating (DR) > 40 preferred - Topical relevance to your site - Editorial link (not paid or exchanged) - Site has real organic traffic (check Ahrefs/Semrush traffic estimate) ### Set up Google Search Console tracking Minimum viable Search Console setup: 1. **Verify ownership** - HTML tag method is most reliable: ```html ``` 2. **Submit sitemap** - Settings > Sitemaps > add `https://yourdomain.com/sitemap.xml` 3. **Monitor weekly reports:** - Performance > Search results: track clicks, impressions, CTR, position - Coverage: watch for "Excluded" spikes (noindex, soft 404, crawl anomaly) - Core Web Vitals: identify poor URLs before they affect rankings - Links: track top linked pages and external link growth 4. **Key Search Console queries to run regularly:** - Filter by "Position > 10 and < 20" - pages close to page 1 are quick wins - Filter by "CTR < 2% and Impressions > 500" - titles/descriptions need work - Filter by "Clicks = 0 and Impressions > 100" - content intent may be misaligned --- ## Gotchas 1. **Noindex on staging left in production** - A `` tag or `X-Robots-Tag: noindex` header copied from staging to production will silently deindex pages. Google does not warn you - pages simply disappear from the index. Always audit robots directives post-deployment. 2. **Self-referencing canonical conflicts with noindex** - If a page has both `` and ``, the signals conflict. Noindex wins for crawling, but the canonical may cause Google to retain the page in index longer than expected. Remove the canonical when noindexing. 3. **Paginated pages canonicaling to page 1 loses deep content** - Canonicalizing all paginated series pages (`/blog?page=2`) to the root (`/blog`) tells Google to ignore the content on pages 2+. Use self-referencing canonicals on each paginated page and ensure internal linking surfaces the paginated content. 4. **Disavow file removes good links with bad** - Submitting a broad disavow file (`domain:example.com`) removes all links from a domain including any legitimate ones. Only disavow specific URLs unless the entire domain is clearly spam/malicious. 5. **Search Console impressions spike without a ranking change** - A sudden impression spike in GSC often indicates Google started showing your page for a new query set, not that your ranking improved. Always check which queries drove the spike before concluding a campaign worked. --- ## Anti-patterns | Mistake | Why it's wrong | What to do instead | |---|---|---| | Keyword stuffing | Triggers spam filters, degrades readability, penalized since Panda (2011) | Use primary keyword naturally 1-3x; rely on semantic synonyms for coverage | | Targeting one keyword per page in isolation | Misses long-tail variations, leaves traffic on table | Build topic clusters: one pillar + supporting pages targeting related intents | | Buying links in bulk | High risk of manual/algorithmic penalty, links devalued quickly | Earn links via digital PR, original research, and genuinely helpful tools | | Ignoring crawl budget on large sites | Low-value pages consume crawl quota, important pages indexed slowly | Block crawl-waste via robots.txt; remove or noindex thin/duplicate pages | | Setting meta robots noindex on staging, forgetting to remove | Pages never indexed in production, invisible traffic impact until audited | Use HTTP auth or IP allowlist for staging; never rely on noindex for security | | Changing URLs without 301 redirects | Destroys accumulated link equity, creates 404 errors | Always 301 redirect old URLs; update internal links; submit new sitemap | --- ## References For detailed implementation guidance on specific topics: - `references/schema-markup.md` - JSON-LD schemas for Article, Product, FAQ, HowTo, LocalBusiness, BreadcrumbList, and SitelinksSearchbox Only load the references file when the task requires it - it is long and will consume context. --- ## Companion check > On first activation of this skill in a conversation: check which companion skills are installed by running `ls ~/.claude/skills/ ~/.agent/skills/ ~/.agents/skills/ .claude/skills/ .agent/skills/ .agents/skills/ 2>/dev/null`.
