1.
Autonomous Playwright Scraper Engine & Container Clusters
SiteHunter operates an advanced, multi-tenant cluster of headless browser nodes designed to navigate the
modern web safely, efficiently, and responsibly. Traditional scraper utilities rely on simple GET requests
(like curl or basic python requests libraries) which fail to parse JavaScript-rendered content, single-page
applications (SPAs), or dynamic layouts.
Our crawler engine deploys containerized Chromium instances driven by Playwright. This ensures that every
page audited is fully rendered in a real headless environment, allowing our extraction algorithms to execute
complex user interaction simulations, bypass script blockages, and parse organic business listings from
local directories, directories indices, and public domain registers.
Key Scraper Node Engineering Attributes:
- Proxy Rotation Outpost Paths: Headless crawler containers route their TCP traffic
through secure, rotating residential and datacenter proxies. This maintains high operational availability,
minimizes rate limit blocks, and distributes crawl weights across isolated nodes.
- User-Agent Telemetry Randomization: Crawlers rotate browser headers, screen viewport
scales, and operating system identifiers to model human-like interactions, ensuring our probes remain
compliant with target platform configurations.
- Parallel Cluster Execution: The Scraper Engine scales scraper containers dynamically
depending on the active queue workload, processing thousands of domains concurrently without thread
lockups or database pool contention.
2.
Lighthouse Technical Performance Auditing Suite
Once a B2B target domain is enqueued and resolved by a Playwright crawler, it undergoes a deep structural
audit mapping various SEO, performance, accessibility, and security guidelines. Our diagnostic engine
implements non-intrusive scanning to evaluate page quality markers:
- Metadata Diagnostics: We audit HTML tag headers, verifying the presence of critical
indexation components. We check if the <title> length is between 50-60 characters, if the <meta
name="description"> falls within the optimal 120-160 character boundary, and verify the presence of
<link rel="canonical"> references to prevent duplicate indexing issues.
- Viewport Scaling Verification: We sweep the page header for a valid <meta
name="viewport"> declaration. Mobile responsiveness is a critical ranking factor, and missing viewports
cause mobile rendering breaks that severely impact PageSpeed.
- Page Load Latencies: We benchmark Core Web Vitals, checking First Contentful Paint
(FCP), Speed Index, Largest Contentful Paint (LCP), and Time to Interactive (TTI). This allows operators
to identify heavy assets, unoptimized scripts, or slow hosting servers.
- SSL Security Verification: Our network registry probes port 443 routes to verify
SSL/TLS certificate validity, ensuring secure HTTPS redirection rules are enforced across the target
domain.
- Console Log Sweep: We capture fatal runtime uncaught JavaScript errors in the browser
console, which can break interactive site elements for clients and lead to poor user experiences.
3. Deep
Generative Lead Synthesis with OpenRouter AI
Finding a B2B lead is only the first step. SiteHunter connects raw telemetry metrics directly with large
language models via the OpenRouter AI core interface. Rather than sending generic, templated outreach emails
that are often flagged as spam, our platform drafts highly contextualized, bespoke copy.
The synthesis engine feeds the exact errors and technical flaws discovered during the Lighthouse and
Playwright audits (such as slow load speeds, missing metadata, broken viewports, or SSL security
vulnerabilities) into a specialized copywriting model. The model automatically formats a professional
outreach draft, explaining to the business owner exactly what is broken on their website and offering
tailored development services. This drastically increases conversion rates, establishes credibility, and
simplifies B2B sales development.

~$1.50 / Lead |
Slow (10-20 leads per hour) |
High manual transcription errors, inconsistent data formats. |
| Bulk List Brokers (Purchased Databases) |
~$0.60 / Lead |
Instant (Static lists) |
Outdated records, high email bounce rates, zero site diagnostic audits. |
| SiteHunter Automation |

5. Ethical
Crawling & Data Compliance Guidelines
SiteHunter is fully committed to maintaining the highest ethical and legal compliance standards in local
web auditing. Our crawling engine operates under strict guardrails to respect web server owners and protect
user data:
- Robots.txt Adherence: Every Playwright node fetches and parses the target domain's
`/robots.txt` configuration before scanning. We honor all crawl-delay parameters and user-agent exclusion
directives.
- Bandwidth & Uptime Safety: Crawlers enforce progressive rate limits and request delays.
We never flood a target server with requests, avoiding any load degradation or thread starvation on target
hosts.
- Zero Consumer PII Collection: SiteHunter is designed solely for public business
directory harvesting and technical SEO profiling. We do not collect, store, or process private consumer
Personable Identifiable Information (PII), aligning strictly with GDPR and CCPA boundaries.
