AI Crawler Detection
AI Crawler Logs show you when AI platforms send their crawlers to index your website content. Understanding which AI bots are visiting your site, how often they return, and which pages they prioritize helps you optimize your content for AI visibility.
What Are AI Crawlers?
AI companies send automated crawlers (bots) to read website content. These crawlers serve multiple purposes:
- Model training - Content is used to train the next version of AI models
- Search indexing - Content is indexed for real-time AI search responses (especially Perplexity, Google AI Overviews)
- Knowledge updates - Existing knowledge bases are updated with fresh content
- Citation verification - AI platforms verify sources before citing them
- Content evaluation - AI systems assess content quality, authority, and relevance
If AI crawlers are not visiting your website, your content is less likely to appear in AI-generated responses. Monitoring crawler activity gives you a leading indicator of future AI visibility.
Crawlers We Detect
Surva.ai identifies visits from all major AI platforms, organized by category:
- ChatGPT / OpenAI - GPTBot (training), ChatGPT-User (real-time browsing), OAI-SearchBot (SearchGPT)
- Claude / Anthropic - ClaudeBot, Claude-Web, anthropic-ai
- Perplexity - PerplexityBot (real-time search indexing)
- Google AI - Google-Extended (AI training), GoogleOther (supplemental crawls)
- Bing AI / Copilot - bingbot, BingPreview (Microsoft Copilot data)
- Meta AI - meta-externalagent, FacebookBot (Meta AI training)
- DeepSeek - Bytespider, DeepSeek (DeepSeek AI)
- Grok / xAI - xAI crawler, Grok (Elon Musk's AI)
- Other AI bots - cohere-ai, AI2Bot (Allen Institute), Diffbot, CCBot (Common Crawl), YouBot (You.com), PetalBot, and others
Detection patterns are stored in the database and cached for fast matching. New crawler user-agent patterns are added as AI platforms launch new bots.
Setting Up Crawler Detection
There are two ways to track AI crawlers on your site:
Option 1: Surva.ai tracking script (recommended)
- Navigate to Site Tracking > AI Crawler Logs
- Copy the tracking script from the setup page
- Add the script to your website's header or footer
- Crawler visits will appear within 24 hours
The tracking script is lightweight (under 2KB) and does not impact page performance or user experience.
Option 2: Server log import
- Go to AI Crawler Logs > Import
- Upload your access log files in Apache or Nginx format
- Surva.ai parses each log entry and identifies AI crawler visits by user-agent string
- Historical data is backfilled from the log timestamps
Server log import captures crawlers that the JavaScript tracking script cannot detect, such as those that do not execute JavaScript.
What the Data Shows
For each crawler visit, you can see:
- Crawler name and platform - Which AI bot visited and which company operates it
- URL visited - The specific page they crawled
- Date and time - When the visit occurred
- Frequency - How often each crawler returns to your site
- Pages per visit - How many pages were crawled in a session
- Top pages - Which pages attract the most AI crawler activity
Understanding Crawler Activity Patterns
Different crawlers behave differently:
- PerplexityBot visits frequently because Perplexity searches the web in real time for every query. High PerplexityBot activity suggests your content is being actively used in Perplexity responses.
- GPTBot crawls less frequently but reads more pages when it visits. Its activity often increases before major model updates.
- Google-Extended activity correlates with Google AI Overview inclusion. If Google's AI crawler is reading your content regularly, you are more likely to appear in AI Overviews.
- ClaudeBot crawls periodically for training data. Unlike Perplexity, Claude does not search the web in real time for most responses.
Correlating Crawls with AI Mentions
One of the most valuable insights from crawler logs is the correlation between crawling and mentions:
- Pages that receive frequent AI crawler visits are more likely to be cited in AI responses
- A spike in crawler activity on a specific page may precede that page being cited or your brand being mentioned for related queries
- Pages that are never crawled are unlikely to appear in AI responses from platforms that rely on web data
Cross-reference your crawler logs with your AI Referral Tracking data and Answer Gaps to build a complete picture.
Robots.txt Configuration
You control AI crawler access through your robots.txt file. Here are common configurations:
Allow all AI crawlers (recommended for maximum visibility):
User-agent: GPTBot Allow: / User-agent: ChatGPT-User Allow: / User-agent: ClaudeBot Allow: / User-agent: PerplexityBot Allow: / User-agent: Google-Extended Allow: / User-agent: meta-externalagent Allow: /
Block specific crawlers (if needed):
User-agent: GPTBot Disallow: /private/ Disallow: /internal/ User-agent: Bytespider Disallow: /
Important: Blocking AI crawlers will reduce your AI visibility. Only block crawlers if you have specific legal or business reasons to do so. If you block a crawler, Surva.ai will still show the blocked attempts in your logs so you can measure the impact.
Frequently Asked Questions
Does more crawler activity mean better AI visibility?
Generally yes, but not always. Frequent crawling means AI platforms are actively indexing your content, which is a prerequisite for appearing in AI responses. However, content quality and authority still determine whether your brand is actually mentioned.
Which crawlers are most important?
It depends on which AI platforms matter most for your audience. For most businesses, GPTBot (ChatGPT), PerplexityBot, and Google-Extended (AI Overviews) are the highest priority because they serve the largest user bases.
Can I see crawler activity for specific pages?
Yes. The AI Crawler Logs view can be filtered by URL path, letting you see which specific pages receive the most AI crawler attention. This helps you identify which content AI platforms value most.
