GPTBot, ClaudeBot, PerplexityBot: What Are AI Crawlers and Why They Visit Your Website
AI bots from ChatGPT, Claude, and Perplexity are crawling Malaysian websites. Here's what they are, what they read, and how to make sure they can access your site.
If you check your website's analytics closely, you might notice some unusual visitors: GPTBot, ClaudeBot, PerplexityBot. These aren't humans. They're AI crawlers — bots sent by AI companies to read your website and feed that information into their AI models.
Here's what they are and why they matter for your business.
What are AI crawlers?
Just like Googlebot crawls websites to build Google's search index, AI crawlers visit websites to build knowledge for AI engines. Each major AI company has its own crawler:
GPTBot — Sent by OpenAI (ChatGPT). When GPTBot reads your website, that information can be used by ChatGPT to answer questions about your business and industry.
ClaudeBot — Sent by Anthropic (Claude). Same principle — Claude reads your site through ClaudeBot and uses that knowledge when users ask relevant questions.
PerplexityBot — Sent by Perplexity AI. Perplexity is an AI search engine that directly cites sources, so being crawled by PerplexityBot can lead to direct traffic from Perplexity.
Google-Extended — Used by Google for Gemini (their AI model). Separate from regular Googlebot, this crawler specifically feeds data into Google's AI features.
Bingbot — While primarily for Bing search, Bingbot data also feeds into Microsoft Copilot, the AI built into Windows and Office.
Why they matter for Malaysian businesses
These crawlers are deciding whether AI will recommend your business. If GPTBot visits your site and finds clear structured data, a good FAQ, and factual content — ChatGPT is more likely to mention you when someone asks about your industry.
If GPTBot can't visit (blocked by robots.txt) or finds nothing useful (no structured data, vague content), ChatGPT will recommend your competitors instead.
How to check if AI bots are visiting your site
Most standard analytics tools like Google Analytics don't show bot visits. You need server-level analytics or a specialized tracker.
ask-ai.my's crawler analytics shows exactly which AI bots visit, how often, and which pages they read. For our own network of Malaysian sites, we've detected 21+ AI crawler visits in the past week — primarily GPTBot and ClaudeBot.
How to make sure they can visit
Check your robots.txt file (yoursite.com/robots.txt). If it contains:
User-agent: GPTBot Disallow: /
Then GPTBot is blocked. Remove this to allow access. Ideally, explicitly welcome all AI crawlers:
User-agent: GPTBot Allow: /
User-agent: ClaudeBot Allow: /
User-agent: PerplexityBot Allow: /
User-agent: Google-Extended Allow: /
What AI bots actually read
AI crawlers read the same HTML your browser sees, but they pay special attention to:
JSON-LD structured data — This is the most valuable content for AI bots. It's a structured format that clearly defines your business entity, services, FAQs, and contact information.
Text content — AI bots extract facts, descriptions, pricing, locations, and other factual claims. The more specific and factual your content, the more useful it is.
FAQ sections — Especially when marked up with FAQPage schema. AI bots can directly match FAQ questions with user queries.
Meta information — Title tags, meta descriptions, and canonical URLs help AI understand page purpose and prevent duplicate content confusion.
They generally ignore: images (they can't see them), JavaScript-rendered content (some bots struggle with this), and login-protected pages.
How often do they visit?
AI crawler frequency varies. Popular, frequently-updated sites get crawled more often. For typical Malaysian business websites, expect:
GPTBot: weekly to monthly visits after initial discovery. ClaudeBot: similar frequency to GPTBot. PerplexityBot: less frequent but increasing. Google-Extended: tied to regular Googlebot crawling schedule.
The key to increasing crawl frequency: update your content regularly, have a valid sitemap, and make sure your site loads quickly. AI bots have time limits — if your site is slow, they may abandon the crawl.
Start tracking your AI crawlers
To see which AI bots visit your site, you can use ask-ai.my's done-for-you service which includes crawler analytics, or run a free audit at ask-ai.my/audit to check if your site is properly configured for AI crawler access.
The businesses getting recommended by AI in 2026 are the ones that welcomed AI crawlers early and gave them clear, structured data to work with. The ones being ignored are the ones that didn't know these bots existed.
Now you know.
