1. Crawlexa's Ethical Harvesting Manifesto
As an enterprise web intelligence provider, Crawlexa firmly believes in an open, competitive, and transparent internet economy. We recognize that public web scraping must be conducted respectfully and sustainably to protect the performance, uptime, and infrastructure costs of target website operators.
2. Server Health & Adaptive Throttling
Unlike unmanaged scripts that hammer target servers with aggressive loops, Crawlexa's distributed extraction clusters implement:
- Automated Backoff (HTTP 429 & 503): If an upstream web server responds with rate limit alerts or temporary service unavailable indicators, our workers instantly back off exponentially and pause requests to that domain.
- Polite Request Delays: Crawlers incorporate jittered delays between subsequent page evaluations to mimic natural browsing cadences.
- Off-Peak Batch Scheduling: Heavy catalog inventory crawls are preferentially executed during the host server's local off-peak hours (typically 01:00 to 05:00 local time).
- Cache-Aware Extraction: HTTP 304 (Not Modified) responses and ETag headers are respected so identical unchanged pages are not re-harvested unnecessarily.
3. Robots Exclusion Protocol (REP) Standards
Crawlexa crawler engines evaluate the Robots Exclusion Protocol (RFC 9309). Our policies distinguish between:
- Legitimate Market Research: In accordance with settled legal precedents (including the US 9th Circuit ruling in hiQ Labs v. LinkedIn), publicly accessible product catalogs, market pricing, and non-confidential directories may be observed for commercial research.
- Administrative & Private Paths: Crawlexa extractors strictly honor directives excluding private internal directories, backend APIs, shopping cart checkout pages, customer account areas (e.g.
/admin/,/checkout/,/account/,/cart/).
4. User-Agent Identification
When conducting general web indexing or public market research, Crawlexa bots may identify themselves with user-agent strings conforming to:
For client-directed private proxy validation where web browsers require standard end-user headers, our workers maintain strict telemetry ensuring connection requests respect host server health.
5. Webmaster Inquiries & Exclusion Requests
If you are a webmaster, site reliability engineer, or infrastructure administrator and have questions regarding automated traffic from our networks, or would like to request custom rate limits or total domain exclusion:
Please email our Webmaster Relations desk at privacy@crawlexa.com or sales@crawlexa.com with the subject line Webmaster Inquiry: [Your Domain] or telephone our operations center at +91 8160867884. We will gladly adjust our concurrency limits or add your domain to our global blocklist within 4 business hours.
