🤖 Overview

lnspiderguy is a web crawling agent operated by Indeed, the world’s largest job search engine, designed to systematically discover, index, and update publicly accessible job listings and employer profiles for its search and matching services. According to Indeed’s official crawler documentation available at https://www.indeed.com/robots.txt and the Indeed Help Center, this bot is one of several Indeed‑operated crawlers (including IndeedBot and IndeedJobBot) that collectively power the platform’s real‑time job inventory. The lnspiderguy user agent is primarily responsible for deep‑crawling employer career pages and job boards to extract structured job data such as title, location, salary, and description, which is then normalized and served to millions of job seekers worldwide.

🌐 Technical Behavior

Indeed’s crawlers, including lnspiderguy, follow a multi‑pass crawl strategy: an initial discovery crawl using broad HTTP GET requests followed by periodic revisits (often daily or weekly) to detect updates or removals. The bot uses IPv4 addresses drawn from Indeed’s own ASN (AS25738), with IP ranges documented at https://www.indeed.com/robots.txt that include blocks like 52.0.0.0/8 and 207.171.0.0/16, although exact ranges change. Requests are made over HTTPS with standard HTTP/1.1 headers and a conservative delay between requests (varies by site, but typically 1–5 seconds). Indeed officially states that their crawlers obey the `Crawl‑Delay` directive in robots.txt. The bot does not execute JavaScript and only parses static HTML and meta tags, relying on schema.org structured data (e.g., JobPosting schema) to extract relevant fields. Indeed’s infrastructure includes a distributed crawling system with multiple agent identifiers – lnspiderguy is one of several dozen used to avoid overwhelming a single site.

📋 robots.txt Compliance

Indeed’s crawlers, including lnspiderguy, are explicitly documented as respecting robots.txt directives. Evidence from Indeed’s own robots.txt file (https://www.indeed.com/robots.txt) shows a line `User‑agent: *` with various Disallow rules, and the company’s support articles state that their crawlers honor site‑level exclusions. However, Indeed encourages site owners to use `Disallow: /` or set a `Crawl‑Delay` directive if they wish to block or throttle the bot. There is no known public report of lnspiderguy ignoring robots.txt – Indeed’s crawlers are designed to be polite and comply with webmaster preferences.

🔍 Detection Indicators

The primary User‑Agent string for this bot is `lnspiderguy/1.0` (or variants such as `lnspiderguy` without a version), as listed in Indeed’s crawler documentation. Additional identifying characteristics include a source IP from Indeed’s registered ASN (AS25738) and the absence of common browser‑like headers (e.g., Accept‑Language, Sec‑Fetch‑Site). Some sites report seeing the bot with the `From` header set to `[email protected]`. Webmasters can confirm lnspiderguy’s identity by reverse‑DNS lookups on hostnames in the indeed.com domain.

📊 Data Usage

Data collected by lnspiderguy is used exclusively for Indeed’s core business: building and maintaining its global job search index. Indeed aggregates job listings from millions of employer websites, normalizes them, and presents them to users in search results, email alerts, and job recommendations. The data is also used for analytics and employer dashboard features, but not for AI training or unrelated product development. Indeed’s privacy policy states that collected job data is stored temporarily and refreshed regularly to ensure accuracy.

⚙️ Rate Limiting Policy

Rate limiting is recommended for lnspiderguy because its distributed, multi‑agent architecture can generate a high volume of requests within a short window, potentially degrading server performance. Site owners should apply threshold‑based blocking (e.g., 100 requests per minute per IP) to protect backend resources while still allowing legitimate crawling – Indeed’s own documentation advises respecting `Crawl‑Delay` and setting explicit limits if needed.
