Workflow
Step 1 — Clarify the Target
Ask (or infer from context):
- Niche: landscaping, plumbing, restaurant, salon, contractor, gym, etc.
- City / Region: Portland OR, Dallas TX, etc.
- Volume: How many leads? (default: 20)
- Min score threshold: Only hot leads? (default: show all ≥ 25)
Step 2 — Search (serper-search skill)
Run targeted Google queries for the niche + city combination. Collect 30–50 organic URLs per run. Filter out aggregators: Yelp, Google Maps, Facebook, TripAdvisor, HomeAdvisor, Houzz, Thumbtack, BBB, Chamber of Commerce directories.
Keep: direct business websites (their own domain)
Skip: aggregator/directory listings
Skip: already-seen domains (deduplication)
Step 3 — Audit (website-auditor skill)
For each URL, run all 8 signals:
- HTTP status (dead/broken?)
- Copyright year (footer scrape)
- Last-Modified HTTP header
- Technology stack (Wappalyzer)
- PageSpeed mobile score (Google PSI API)
- Mobile responsiveness (viewport meta tag)
- SSL certificate
- Design age signals (tables, Flash, inline styles, no OG tags)
Process in batches of 5 concurrently. Add 1–2s delay between batches.
Step 4 — Enrich (contact-enrichment skill)
For each audited site:
- Scrape homepage + /contact + /about for emails and phones
- If no email found → WHOIS lookup
- If still no email → Hunter.io domain search
- Extract business name from
<title>tag
Step 5 — Score & Deliver (lead-scorer skill)
Apply scoring rubric → assign tier (🔥🟡🔵⚪) → write to Google Sheet.
Step 6 — Summary Report
After the run, report back:
✅ Scan complete.
Niche: [niche] | City: [city]
URLs scanned: [n]
Leads written to sheet: [n]
🔥 Hot (80–100): [n] leads
🟡 Warm (50–79): [n] leads
🔵 Lukewarm (25–49): [n] leads
⚪ Cold (0–24): [n] leads
Top 3 hottest leads:
1. [business] — [url] — Score: [n] — [email]
2. ...
3. ...
Sheet: [Google Sheet URL or name]
Error Handling
- Dead site (connection error) → still log it, score as hot (it's dead — they need a new site)
- No contact found → leave blank, mark "No contact found" in Notes column
- PageSpeed API timeout → skip that signal, don't block the pipeline
- Rate limited by a site → skip, log, continue
