robots.txt Crawl-delay

🛠️ What is Crawl-delay in robots.txt?

The crawl-delay is a directive you can specify in your robots.txt file to instruct search engine crawlers how long to wait between requests to your server. This helps manage server load by controlling the rate at which search engines crawl your site.

⭐ Why is Crawl-delay Important in SEO?

Using crawl-delay can prevent your server from being overwhelmed by too many requests from search engine crawlers, ensuring that it remains responsive to real users. This is especially valuable for sites with limited server resources or when experiencing high traffic.

⚙️ How Does Crawl-delay Work?

1. A search engine crawler requests the robots.txt file of a website.
2. The crawler detects the crawl-delay directive in the file.
3. The crawler waits the specified amount of time between each request to the server.
4. This helps manage crawl rates and balances server load.

📌 Examples of Crawl-delay Usage

• Specifying 'Crawl-delay: 10' in robots.txt to indicate a 10-second delay between requests.
• Applying different crawl-delay values for different search engines.
• Using crawl-delay to manage traffic on e-commerce sites during peak shopping seasons.

✅ Best Practices for Using Crawl-delay

• Test different crawl-delay values to find an optimal balance between crawl efficiency and server load.
• Monitor server performance and adjust crawl-delay settings as needed.
• Use crawl-delay in conjunction with other robots.txt directives like Disallow and Allow to fine-tune crawler access.

⚠️ Common Mistakes with Crawl-delay

• Setting a crawl-delay that is too long, resulting in delayed indexing.
