Bot User-Agent: localcombot

🤖 Overview

LocalComBot is a web crawler operated by Local.com, a local business search engine and directory platform headquartered in Irvine, California. First documented in user-agent strings around 2010, the bot is designed to systematically discover and index business listings, addresses, phone numbers, websites, and operational details from public web pages to populate Local.com’s directory and search results. The crawler’s primary purpose is to keep Local.com’s database current and comprehensive for users searching for nearby services, restaurants, and retail outlets.

🌐 Technical Behavior

LocalComBot typically crawls at a moderate frequency, sending requests from IP ranges that belong to Local.com’s own infrastructure, often originating from datacenters in the United States. According to observations shared on webmaster forums and robotstxt.org, the bot issues sequential GET requests with relatively short delays between pages when not explicitly rate-limited. It follows HTML links and sitemap directives, and its crawl depth is usually limited to publicly accessible pages. The bot uses standard HTTP/1.1 and supports gzip compression. Its crawl pattern tends to focus on pages containing structured business data such as “contact us” forms, footer links, and business directories. The official documentation at http://www.local.com/bot.html (now often redirected) originally stated that the bot checks for a crawl-delay directive in robots.txt to control its visit interval, but in the absence of such a directive, it may send requests every few seconds.

📋 robots.txt Compliance

Local.com has publicly stated that LocalComBot respects the Robots Exclusion Protocol. The bot reads the robots.txt file before crawling and obeys Disallow directives. Evidence from multiple webmaster communities indicates that when a site explicitly blocks the bot via Disallow: / or targets specific directories, the crawler ceases access to those paths. However, because the bot is designed to index business data, it may still attempt to access pages that contain business information unless explicitly excluded.

🔍 Detection Indicators

The primary identification string is: Mozilla/5.0 (compatible; LocalComBot/1.0; +http://www.local.com/bot.html). Some variations append additional details such as “AppleWebKit/537.36” or “Gecko” but the core LocalComBot/1.0 token remains consistent. The bot does not typically send a custom From: or X-Forwarded-For header, but its IPs reverse‑resolve to *.local.com or nearby datacenter ranges. Behavioral fingerprints include requests for /robots.txt followed by rapid crawling of pages containing address‑related content, and a user‑agent string that is never forgery‑prone.

📊 Data Usage

The collected data is used exclusively for Local.com’s search index and business directory. Extracted information—such as business names, phone numbers, addresses, hours of operation, and website URLs—is consolidated into Local.com’s database to serve user queries. The platform also uses this data to power location‑based advertising and local SEO analytics. Local.com has not publicly stated that data is used for AI training, but the raw content may be incorporated into ranking algorithms and internal knowledge graphs.

⚙️ Rate Limiting Policy

While LocalComBot is a legitimate agent, it is recommended to rate‑limit its requests because it can generate hundreds of hits per hour on large directory sites, potentially degrading server performance for other users. A reasonable policy is to set a crawl‑delay of 10–30 seconds in robots.txt or to implement a threshold that blocks the IP after a certain number of requests per minute, ensuring fair resource allocation without permanently banning a benign crawler.
