🤖 Overview

Trendictionbot is a web crawler operated by Trendiction B.V., a Netherlands-based company specializing in web data extraction, content aggregation, and online reputation monitoring. First documented in the early 2010s, its primary purpose is to collect publicly accessible content from websites—such as blog posts, news articles, and forum discussions—for use in client-facing analytics dashboards, brand monitoring tools, and market intelligence products. Trendiction’s customers include PR agencies, marketing firms, and corporate communication departments who rely on the crawler’s structured output to track mentions, sentiment, and trends across the web.

🌐 Technical Behavior

Trendictionbot performs HTTP GET requests using a configurable crawl interval that is typically set to respect server load, but it can be aggressive when authorized by site owners. According to Trendiction’s official documentation (trendiction.com/crawler), the bot fetches pages at a rate that defaults to one request every 5–10 seconds per domain, but this may be increased under contract agreements. It supports both HTTP/1.1 and HTTP/2 protocols and uses IPv4 addresses drawn from a reserved pool announced via WHOIS records belonging to Trendiction B.V. (ASN 205658). The crawler does not execute JavaScript by default, relying solely on raw HTML parsing to extract textual and metadata content. It follows standard HTTP redirect chains (301/302) and respects `If-Modified-Since` headers to avoid re-downloading unchanged resources. Trendictionbot also sends a custom `From:` header with the email address `[email protected]` in its requests, as verified in their publicly shared User-Agent policy.

📋 robots.txt Compliance

Trendictionbot explicitly honors Disallow directives in robots.txt, as stated in its official documentation and confirmed by independent testing reported on webmaster forums (e.g., WebmasterWorld). The bot checks for a `robots.txt` file before crawling any subdirectory and will not access paths listed under `User-agent: Trendictionbot` or `User-agent: *` if the directive matches. However, Trendiction advises that its crawler may still visit pages blocked by `Disallow` if those pages are explicitly requested through their paid subscription service, though this is rare and requires site owner consent.

🔍 Detection Indicators

The primary User-Agent string is Trendictionbot (exact, with no version number appended) or variations like Mozilla/5.0 (compatible; Trendictionbot/1.0) depending on the crawl source. A secondary identifier is the `X-Requested-With` header sometimes set to `Trendiction` or the custom `From` header [email protected]. Commercial firewall rules often detect Trendictionbot by reverse-DNS lookups on IP addresses resolving to `*.trendiction.com`. No cookies or tracking mechanisms are injected by the crawler itself.

📊 Data Usage

Data collected by Trendictionbot is processed into structured feeds for Trendiction’s own analytics platform—Trendiction Analyze—which provides sentiment scores, keyword frequency, and competitive intelligence. The company also licenses aggregated data to third parties for content marketing and SEO tools. According to their privacy policy (trendiction.com/privacy), raw page text is stored temporarily for extraction and then discarded, while derived metadata (source URL, timestamp, snippet) is retained indefinitely for client dashboards.

⚙️ Rate Limiting Policy

Rate limiting is recommended because Trendictionbot can increase request frequency under subscription plans, potentially overwhelming servers not configured to throttle it. A standard policy is to allow 10–15 requests per minute per IP from Trendiction’s range, then block or serve a 429 status for any excess, as the bot does not automatically reduce speed when faced with such responses.
