Questions and Answers
Understanding robots.txt: validation and URL checking
What is robots.txt?
▼
Robots.txt is a text file in the root of a website that tells search engines which pages and sections can be indexed and which should be excluded from search.
Why check robots.txt for errors?
▼
Errors in robots.txt can prevent search engines from indexing important pages or, conversely, allow indexing of administrative sections. Validation helps avoid such problems.
What does the Disallow directive mean?
▼
Disallow tells a search engine bot that access to a certain URL or section of the site is forbidden for indexing.
What does the Allow directive mean?
▼
Allow is used to explicitly permit indexing of specific URLs even if they fall under a broader Disallow rule.
Can I check a specific URL in robots.txt?
▼
Yes, our service allows you to enter a page address and check whether it is allowed for indexing or blocked by Disallow directives.
What errors are most common in robots.txt?
▼
The most common errors are incorrect syntax, extra spaces, wrong file paths, missing User-agent directive, or conflicts between Allow and Disallow rules.
Does robots.txt affect SEO?
▼
Yes, a correct robots.txt helps search engines properly crawl your site. Errors can lead to important pages being excluded from the index or technical sections being indexed.
Can I completely block a site with robots.txt?
▼
Yes, using the Disallow: / directive for all User-agents. However, this is not a secure protection—the file is visible to everyone, including competitors.
How often should I check robots.txt?
▼
It should be checked whenever the file is updated or a new project is launched, and also monitored regularly to avoid errors.
Can robots.txt be used to protect personal data?
▼
No, robots.txt only gives recommendations to search engines. To protect confidential data, use passwords and server access restrictions.
Why include a Sitemap in robots.txt?
▼
Specifying a Sitemap helps search engines quickly find and index all pages of the site. The Sitemap directive is usually placed at the bottom of robots.txt.
What is the Host directive in robots.txt?
▼
The Host directive specifies the main domain of the site. This is important if the site is available under different domains or subdomains.
