🤖 Overview

The Giant bot is operated by Giant Ltd., a web data extraction and search technology company. Its primary purpose is to crawl publicly accessible web content for indexing into the Giant search engine and to feed data into Giant’s proprietary AI training pipelines. First documented in their official bot policy page at http://giant.com/bot (archived 2021), the crawler is designed to support both search result freshness and machine learning model improvement.

🌐 Technical Behavior

GiantBot uses a custom HTTP client with a reported crawl rate of between 5 and 20 requests per second per source IP, depending on the site’s response times. Its IP ranges are drawn from a block listed in the ASN for Giant Ltd. (AS39874), though no public CIDR list is maintained. The bot makes HEAD requests before each full GET to assess resource availability, and it follows all redirects up to five hops. It prioritizes HTML, PDF, and plain-text documents while ignoring binary media files unless explicitly requested. GiantBot’s crawl pattern is depth-first with a maximum of 10 levels per domain, and it pauses at least 0.5 seconds between consecutive requests to the same host.

📋 robots.txt Compliance

According to Giant Ltd.’s official documentation, GiantBot fully honors all Disallow directives in robots.txt and supports the Crawl-Delay directive with a minimum of 10 seconds. A 2022 study by Web Robots Analysis (webrobots.io) confirmed that GiantBot respects both Allow and Disallow rules, and it does not attempt to bypass restrictions via alternate user-agent strings. No violations have been reported in public security advisories.

🔍 Detection Indicators

The primary User-Agent string is Giant/1.0 (compatible; GiantBot; +http://giant.com/bot). A secondary variant Mozilla/5.0 (compatible; Giant/1.0; +http://giant.com/bot) is also observed. Behavioral fingerprints include sequential request numbering in the X-Giant-Request-Id header and a consistent 1-second delay between requests during low-load periods. No version history is publicly maintained.

📊 Data Usage

Collected data is used exclusively for search indexing and AI training for Giant’s natural language understanding models, as stated in their privacy policy. Giant Ltd. commits to not storing personal identifiable information beyond 30 days, and aggregated data is used to improve search relevance and content classification. No evidence of data resale or third-party sharing has been found in public sources.

⚙️ Rate Limiting Policy

GiantBot is rate-limited because its moderate request frequency can still overwhelm small sites; threshold-based blocking (e.g., >20 requests per second) is recommended to ensure fair resource allocation while allowing legitimate crawling. This policy aligns with Giant Ltd.’s own guidelines, which advise site operators to contact them for custom rate adjustments.
