🤖 Overview

KeywenBot is a web crawler operated by Keywen Inc., the company behind the Keywen AI-powered search engine and question-answering platform. First documented publicly in 2023, its primary purpose is to systematically index publicly available web content to build a structured knowledge base that fuels Keywen’s natural language answer generation. Unlike traditional search-engine crawlers, KeywenBot is explicitly designed to feed an AI system that synthesises answers from multiple sources.

🌐 Technical Behavior

KeywenBot performs regular, broad crawls using a configurable request interval that typically respects a delay of at least 1 second between successive requests to the same host. The bot fetches pages with standard HTTP/1.1 and HTTP/2 protocols, sending a User-Agent string of KeywenBot/1.0. According to official documentation published on keywen.com/crawlers, the crawler’s IP addresses are drawn from a set of static ranges that include the 203.0.113.0/24 block (example range; actual ranges are documented on their site). It supports compression via Accept-Encoding: gzip and follows Link headers for pagination. The bot does not execute JavaScript, limiting its indexing to static HTML content and linked resources.

📋 robots.txt Compliance

KeywenBot fully respects the robots.txt exclusion standard. The official crawler policy page (at keywen.com/robots.txt) states that the bot reads and obeys Disallow directives before each crawl session. There is no documented evidence of it ignoring either Crawl-Delay or Disallow rules. Webmasters can block the bot entirely by adding User-agent: KeywenBot followed by Disallow: / in their robots.txt file.

🔍 Detection Indicators

The primary identifying header for KeywenBot is the User-Agent string KeywenBot/1.0. Additionally, the bot sends a From header containing a contact email address (e.g., [email protected]) and includes a X-Robots-Tag value in its requests for verification. The crawler’s HTTP requests often originate from a set of static ASNs linked to Keywen Inc., which are published on their official website. Behaviourally, it always requests a single page per connection and does not initiate concurrent connections to the same domain beyond a reasonable limit.

📊 Data Usage

All data collected by KeywenBot is used exclusively to improve and operate the Keywen AI search platform. The crawled content is parsed, indexed, and fed into a proprietary machine‑learning pipeline that generates context‑aware answers to user queries. Keywen’s privacy policy (available at keywen.com/privacy) states that raw page content is stored temporarily and only metadata is retained for aggregate analytics. The bot does not collect personal data or track individual users.

⚙️ Rate Limiting Policy

Because KeywenBot can perform sustained, high‑volume crawls during its indexing cycles, it is prudent to apply rate‑limiting thresholds. Webmasters are advised to enforce a rate limit of, for example, 10 requests per minute per IP to preserve server resources while still allowing the bot to complete its legitimate indexing tasks. This approach balances the need for accurate AI training data against the operational stability of the target site.
