🤖 Overview

Spider_Bot is a web crawler operated by Spider Technologies Inc., a San Francisco-based data analytics company that launched its public crawler in August 2021. The bot’s primary purpose is to collect publicly accessible web content for AI training datasets, market intelligence reports, and the company’s proprietary web search index, as detailed in Spider’s official documentation at https://spider.com/bot.

🌐 Technical Behavior

Spider_Bot uses a distributed crawling architecture with requests originating from a dynamic IP pool across IPv4 ranges 104.20.0.0/16 and 172.64.0.0/16, according to Spider’s published IP list. The bot sends HTTP/1.1 and HTTP/2 requests at a default rate of one request every 10 seconds per domain, though this adjusts based on server response times and the presence of a Crawl-Delay directive. An Accept-Language header of “en-US” is always included, and the User-Agent string is rotated every 48 hours to avoid pattern-based blocking.

📋 robots.txt Compliance

Spider’s official robots.txt policy page (https://spider.com/robots) states that Spider_Bot fully respects Disallow directives and honors a Crawl-Delay of at least 30 seconds if specified. However, third-party audits by the Webmaster Forum (2022) noted that the bot occasionally ignores Disallow rules for paths returning a 200 status for blocked pages, though Spider has since patched this behavior in version 2.1.

🔍 Detection Indicators

The primary User-Agent string is “Mozilla/5.0 (compatible; Spider_Bot/2.0; +https://spider.com/bot)” and a legacy variant “Spider_Bot/1.0”. Identifying HTTP headers include a custom “X-Spider-Bot: true” and a “From: [email protected]” header, as documented in Spider’s GitHub repository (https://github.com/spidertech/crawler).

📊 Data Usage

Collected data feeds Spider’s machine learning models for natural language understanding, powers their web search API used by enterprise clients, and contributes to aggregated market trend reports. Spider claims that all personally identifiable information is stripped before data enters training pipelines, per their privacy policy.

⚙️ Rate Limiting Policy

Rate limiting is recommended because Spider_Bot’s default speed can overwhelm shared hosting environments; most webmasters implement a threshold of 100 requests per minute before returning a 429 status, as advised by Spider’s own rate limit best practices guide.
