Workflow 1: Single Page Audit
Run a comprehensive technical audit of one URL. Start with Lighthouse for performance scores, then get page optimization details, and optionally extract content structure.
Step 1 — Lighthouse Audit
Tool: on_page_lighthouse
Input: {
"url": "https://example.com/landing-page",
"for_mobile": true
}
Set for_mobile: true for mobile-first analysis (Google's default ranking signal). The response includes scores for performance, accessibility, best_practices, and seo (each 0-1, multiply by 100 for percentage). Drill into specific audits in the audits object for actionable recommendations.
Step 2 — Page Optimization Data
Tool: on_page_instant_pages
Input: {
"url": "https://example.com/landing-page"
}
Returns page-level SEO signals: title tag, meta description, canonical URL, heading structure (h1-h6 counts), internal/external link counts, image alt text coverage, page size, load time, and HTTP status. Use this to identify missing meta tags, broken heading hierarchy, or oversized pages.
Step 3 — Content Extraction
Tool: on_page_content_parsing
Input: {
"url": "https://example.com/landing-page"
}
Extracts structured content: paragraphs, headings, lists, and tables in clean format. Use this to analyze content quality, keyword density, or feed text into further analysis.
Workflow 2: Content Landscape Analysis
Understand how a topic is covered across the web — what content exists, overall sentiment, and trend direction.
Step 1 — Search Content
Tool: content_analysis_search
Input: {
"keyword": "headless CMS comparison",
"search_mode": "as_is",
"limit": 50
}
Returns up to 50 pages matching the keyword with metadata: page type (ecommerce, news, blog, message-board, organization), sentiment (positive/negative/neutral), word count, date published, and social metrics. Use search_mode: "as_is" for exact phrase or "relevance" for semantic matching.
Step 2 — Summary Metrics
Tool: content_analysis_summary
Input: {
"keyword": "headless CMS comparison"
}
Returns aggregated metrics: total pages found, average sentiment score, content type distribution, and top domains covering the topic. Use this for a quick market snapshot before diving into individual pages.
Step 3 — Phrase Trends
Tool: content_analysis_phrase_trends
Input: {
"keyword": "headless CMS comparison",
"date_from": "2025-01-01"
}
The date_from parameter is required. Returns trend data showing how content publication volume for this phrase changed over time. Use this to identify rising topics, seasonal patterns, or declining interest. Set date_from to 6-12 months back for meaningful trends.
Workflow 3: Technology Detection
Discover the full technology stack of any domain — CMS, frameworks, analytics, CDN, hosting, email services, and more.
Tool: domain_analytics_technologies_domain_technologies
Input: {
"target": "example.com"
}
Returns categorized technology list: content management systems (WordPress, Shopify), JavaScript frameworks (React, Next.js), analytics (Google Analytics, Hotjar), CDN (Cloudflare, Fastly), hosting provider, advertising platforms, email services, and more. Each technology includes category, name, and version when detectable.
Use cases:
- Competitive intelligence — see what tools competitors use
- Sales prospecting — find companies using a specific technology
- Migration planning — understand the current stack before proposing changes
Workflow 4: Domain Intelligence
Get registration and ownership data for any domain.
Tool: domain_analytics_whois_overview
Input: {
"target": "example.com"
}
Returns WHOIS data: registrar, creation date, expiration date, updated date, name servers, registrant organization (when not privacy-protected), and domain status codes. Enriched with backlink summary stats when available.
Use cases:
- Due diligence — verify domain age and ownership
- Competitor research — find related domains by registrant
- Expired domain hunting — check expiration dates
Interpreting Lighthouse Scores
| Score Range | Rating | Action |
|---|
| 90-100 | Good (green) | Maintain current optimizations |
| 50-89 | Needs Improvement (orange) | Address specific audit failures |
| 0-49 | Poor (red) | Prioritize immediate fixes |
Key Lighthouse audit categories:
- Performance — LCP, FID, CLS, TTFB, speed index. Most impactful for rankings.
- Accessibility — Color contrast, ARIA labels, heading order, alt text. Affects both SEO and compliance.
- Best Practices — HTTPS, console errors, deprecated APIs, image aspect ratios.
- SEO — Crawlability, meta tags, structured data, mobile viewport, link text.
Always check the audits object for specific failing items. Each audit has a score (0-1), title, and description explaining what to fix.
Content Analysis Metrics
When interpreting content_analysis_search results:
| Metric | Values | Meaning |
|---|
sentiment_connotations | positive / negative / neutral | Overall tone of the content |
connotation_types | anger, happiness, sadness, fear, love, fun | Emotional tone breakdown |
page_types | ecommerce, news, blogs, message-boards, organization | Content category |
social_metrics | facebook, twitter shares | Content virality indicators |
word_count | integer | Content depth — higher often means more comprehensive |
spam_score | 0-100 | Quality indicator — lower is better |
