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
User: "Run a full technical audit on our homepage at https://acme.co"
User: "How is the topic 'AI code review' being covered online? Show me trends."
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.
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.
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.
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.
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.
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.
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.
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
