Bot Operator Directory

Ahrefs runs a purpose-built crawling infrastructure focused on large-scale web discovery, backlink analysis, rank tracking, and SEO intelligence. Its bots continuously traverse the public web to map link graphs, measure content changes, and evaluate site authority signals. Ahrefs traffic is generally straightforward to identify, with stable user agents, predictable crawl patterns, and IP ranges that reflect its dedicated, non-consumer indexing infrastructure.

Amazon runs a sprawling automation footprint that powers its retail marketplace, AWS ecosystem, adtech products, voice-assistant services, and performance intelligence systems. Its crawlers span everything from product ingestion and offer matching to brand protection, link health checks, and Alexa-related retrieval. While Amazon’s bot activity is significant, public documentation is thinner than Google’s; identification typically relies on their published AmazonBot specs, IP disclosures, and consistent DNS patterns tied to AWS infrastructure.

Google operates the world’s largest search and indexing infrastructure, alongside a wide ecosystem of automated systems for advertising, speed testing, mobile compatibility checks, structured-data validation, and product feed verification. Google’s traffic is diverse but well-documented, and most of its automated agents are first-party identifiable through dedicated user-agents, published IP ranges, and decades-old crawling behaviors.

Meta operates a broad network of automated systems that support its social platforms, threat-intelligence pipelines, content previewing, link safety checks, and large-scale data integrity workflows. Its crawlers handle everything from URL scraping for Open Graph previews to security scanning and misinformation detection. Meta’s bot surface is substantial but relatively low-noise, and most traffic can be tied back to well-defined user agents, stable ASN patterns, and predictable fetch behaviors rooted in their global delivery and security infrastructure.

Microsoft maintains a wide constellation of automated agents across Bing search, enterprise security products, cloud telemetry, indexing pipelines, and performance diagnostics. Its traffic includes everything from traditional web crawling and multimedia indexing to threat intelligence harvesting and link verification for Microsoft 365. While broad, Microsoft’s bot activity is generally transparent: official user agents, published IP ranges, and characteristic fetch patterns across Azure networks make most of its automation reliably identifiable.

Moz operates a focused crawling and data-collection infrastructure designed to support SEO research, link analysis, rank tracking, and site auditing. Its bots scan the public web to build link indexes, assess domain authority signals, and surface technical SEO insights. Moz’s automated traffic is typically easy to classify, relying on clearly declared user agents, conservative crawl rates, and infrastructure patterns consistent with its commercial research tooling rather than general-purpose indexing.

OpenAI is an AI research and product company behind models like GPT-4, GPT-5 and the ChatGPT platform. It operates several bots and automated agents that access web content for search, training data collection (where allowed), content retrieval, and live browsing on behalf of users. Unlike generic cloud traffic, OpenAI’s automated access is increasingly first-party identified via dedicated user-agents and documented IP egress ranges.

Yandex operates a large-scale crawling and automation ecosystem that powers its search engine, advertising network, analytics products, and content classification systems. Its bots perform traditional indexing alongside media analysis, link verification, and quality assessment across the web. Yandex’s automated traffic is well-structured and historically consistent, with identification typically possible through documented user agents, long-standing crawl behaviors, ASN, DNS, and IP ranges tied to its regional infrastructure. From February 22, 2018, Yandex stopped supporting the Crawl-delay directive.
