Introduction to Robots.txt
Google has released new documentation that explains how to use Robots.txt to control search engine crawlers and other bots. Robots.txt is a file that allows publishers and SEOs to manage how their website is crawled and indexed by search engines. The documentation provides examples of how to block specific pages, restrict certain bots, and manage crawling behavior with simple rules.
What is Robots.txt?
Robots.txt is a 30-year-old web protocol that is widely supported by search engines and other crawlers. It’s a way for website owners to communicate with search engines and other bots, telling them which parts of the site to crawl and which to avoid. Google Search Console will report a 404 error message if the Robots.txt file is missing, but this can be resolved by creating a blank file or waiting 30 days for the warning to drop off.
Basic Uses of Robots.txt
The new documentation starts with the basics, introducing Robots.txt as a way to manage crawling. It explains that you can leave your robots.txt file empty if your whole site can be crawled, or you can add rules to manage crawling. For example, you can create custom rules to restrict specific pages or sections of your site. As Google’s documentation states, "You can leave your robots.txt file empty (or not have one at all) if your whole site may be crawled, or you can add rules to manage crawling."
Advanced Uses of Robots.txt
The advanced uses of Robots.txt allow for more granular control over crawling. Some of the capabilities include:
- Targeting specific crawlers with different rules
- Blocking URL patterns like PDFs or search pages
- Enabling granular control over specific bots
- Supporting comments for internal documentation
Editing and Testing Robots.txt
The good news is that editing the Robots.txt file is simple. It’s a text file with simple rules, and you can use a basic text editor to make changes. Many content management systems also have a way to edit the file, and there are tools available for testing if the Robots.txt file is using the correct syntax.
Conclusion
In conclusion, Google’s new documentation provides a comprehensive guide to using Robots.txt to control search engine crawlers and other bots. Whether you’re a beginner or an advanced user, the documentation has something to offer. By understanding how to use Robots.txt, you can take control of your website’s crawling and indexing, and improve your search engine rankings. To learn more, you can read the full documentation here.
