Agents blocked by the most top websites
See which agents are most frequently impersonated, and how spoofing activity changes over time. A visit is considered spoofed when it claims a recognized agent identity but fails that agent's supported authentication method, such as verified IP or Web Bot Auth.
Active Threat: AI Bot Spoofing Campaign
We are observing a widespread campaign impersonating AI bots to scan websites for vulnerabilities. The attacker appears to be targeting credential and configuration paths used by AI coding tools. Contact us for more information.

Website categories receiving the most referrals from AI chat
The Index is updated daily with completed days of traffic, security, and referral data from more than 5,000 websites using Agent Analytics and AI Chat Referral Tracking. The current partial day is excluded. Percentage-change tags compare the current period with the preceding period of the same duration. Agent names, operators, and classifications come from the Agent Directory, which is updated as new agents are discovered or existing agents change. Website categories follow the taxonomy used by Google AdSense. Participating websites are not a random sample of the entire web, and the qualifying set can change as websites connect, disconnect, or cross activity thresholds. Results characterize the observed network and broader directional trends; they should not be interpreted as a precise census of global web traffic.
Only websites meeting minimum activity and data-quality requirements are included. Internal, test, incomplete, or anomalous data is excluded. Bot traffic percentages use total server traffic as their denominator. AI chat referral percentages use estimated human traffic, calculated by excluding identified bot visits from total server traffic. Rates are calculated for each qualifying website first, then averaged across websites and completed days. This gives each website equal weight regardless of traffic volume and prevents a small number of high-traffic websites from dominating the results. Daily charts are not smoothed, allowing normal seasonality to remain visible.
An agent's Robots.txt Effectiveness estimates the reduction in its request rate associated with a full disallow rule. For each completed day, Known Agents establishes an agent-specific baseline from qualifying websites where that agent is allowed, adjusts the baseline for the overall traffic of each website where the agent is disallowed, and compares the expected activity with the activity actually observed. Only website-day observations with sufficient site traffic, agent activity, cross-site coverage, and expected volume qualify. Scores also require repeated observations across multiple websites and days. When an agent publishes a supported authentication method, only verified traffic is attributed to it.
Each qualifying website-day contributes equally. Scores range from 0%, meaning no measurable reduction, to 100%, meaning no qualifying requests were observed where the agent was disallowed. The headline Robots.txt Effectiveness metric gives each qualifying agent equal weight. Because this is an observational estimate rather than a controlled experiment, it measures an association with robots.txt rules but does not claim that robots.txt caused every observed difference. Top Blocked Bots is calculated separately using daily robots.txt scans of Similarweb's top 1,000 websites.
Spoofing statistics measure traffic from visits that claim the identity of a known agent but fail a supported authentication method, such as published IP verification or HTTP message signatures. Each agent's daily rate is calculated against total server traffic for every qualifying website, then averaged across websites. A failed check indicates that the visit was likely impersonating the named agent; it does not identify the software or operator that actually made the request. Agents without a supported authentication method are not included in these measurements.
AI chat referral statistics count directly observed human visits carrying a recognized AI platform in the referring URL or campaign source. Visits without usable referral information cannot be attributed to an AI platform. Citation statistics are estimates based on requests from agents known to retrieve content for AI platforms. Those requests indicate that content may have informed a response, but they do not confirm that a source appeared as a citation to a user. Because AI platforms do not provide a complete public record of their sources, citation results should be interpreted as directional patterns rather than exact citation counts.

Absolutely. We welcome thoughtful research into how agents and bots are changing the web. Tell us about your research question, timeframe, and intended use. Depending on the scope and data constraints, we may be able to provide additional context, compare approaches, or explore a joint analysis.
Yes. If you need a breakdown by agent, operator, activity type, website category, or time period that is not shown here, contact us. When the underlying data supports it, we can examine the question and provide a focused analysis.
Agent Analytics shows which agents and bots visit your website, what they access, and how their activity changes over time. AI Chat Referral Tracking measures the human traffic arriving from AI chat platforms. Automatic Robots.txt helps manage which bots can access your content.
