⚠️ Caution: Advanced Configuration
Modifying your robots.txt file effectively controls who can
access your website. Incorrect rules can accidentally de-index
your entire site from Search Engines like Google. This tool
generates valid syntax rules based on your selection. It does
not analyze your specific website needs.
We strongly suggest testing any changes in Google Search Console or with CrawlerCheck before deploying to production.

Resource & Impact Analysis
Managing bot traffic is about more than just security. It's about optimizing your infrastructure and protecting your digital assets. Unchecked crawler activity can have significant downstream effects on your website's performance and business metrics.
📉 Server Load & Bandwidth
Every request from a bot consumes CPU cycles, RAM, and bandwidth. Aggressive scrapers can simulate a DDoS attack, slowing down your site for real human users and increasing your hosting costs, especially on metered cloud platforms.
💰 Crawl Budget Waste
Search engines like Google assign a "Crawl Budget" to your site. A limit on how many pages they will crawl in a given timeframe. If low-value bots clog your server queues, Googlebot may reduce its crawl rate, delaying the indexing of your new content.
🤖 AI & Data Privacy
Modern AI bots (like GPTBot and CCBot) scrape your content to train Large Language Models. While not malicious, they use your intellectual property without providing traffic back. Blocking them allows you to opt-out of having your data used for AI training.
🕵️ Competitive Intelligence
Many "SEO Tools" and commercial scrapers are used by competitors to monitor your pricing, copy your content strategy, or analyze your site structure. Restricting these bots protects your business intelligence.
Understanding Web Crawlers & Bots
Web crawlers (also known as spiders or bots) are automated software programs that browse the internet. CrawlerCheck classifies them into distinct categories to help you decide which ones to allow and which to block.
Search Engines Bots
Bots like Googlebot and Bingbot are essential for your website's visibility. They index your content so it appears in search results. Blocking these will remove your site from search engines.
AI Data Scrapers
Bots like GPTBot (OpenAI), ClaudeBot (Anthropic) and PerplexityBot (PerplexityAI) crawl the web to collect data for training Large Language Models (LLMs). Blocking them prevents your content from being used to train AI, but does not affect your search rankings.
SEO Tools & Scrapers
Marketing tools like Ahrefs and Semrush scan your site to analyze backlinks and SEO health. While useful for SEO audits, aggressive scrapers can consume server bandwidth and impact performance.
