What does this tool do?

The SERPInsight Bulk Robots.txt Tester allows you to test up to 50 URLs at once to see if they are blocked by a website's `robots.txt` file.

`robots.txt` is a set of instructions for web crawlers (like Googlebot) telling them which pages they can or cannot visit. This tool downloads the `robots.txt` file from the target site and simulates how a specific bot (like Googlebot or Bingbot) would interpret the rules for each URL you enter.

How to use it

1

Enter URLs

Paste your list of URLs into the text area. Make sure to include the full path (e.g., `https://example.com/admin`).
2

Select User Agent

Choose which bot you want to simulate (e.g., Googlebot, Bingbot, or Facebook). Different bots may see different rules.
3

Run Test

Click "Start Test". The tool will fetch the `robots.txt` file and check each URL against it instantly.

How to read the results

Allowed

The bot is permitted to crawl this URL. This is good for public content.

Blocked

The bot is forbidden from crawling this URL by a specific `Disallow` rule.

Matched Rule

We show you the exact line in the robots.txt file that caused the block or allowance.

Line Number

The specific line number in the file so you can easily find and edit it.

Frequently Asked Questions

Does "Allowed" mean my page is indexed?

No. "Allowed" simply means the bot can *visit* the page. To be indexed, the page must also not have a `noindex` meta tag and must be high enough quality for Google to select it.

Why is my URL blocked by a wildcard (*)?

If there is no specific rule for your chosen User-Agent (e.g., Googlebot), the file falls back to the `User-agent: *` section. If that section has a `Disallow: /` rule, it blocks all bots that don't have their own specific rules.

Can I use this to block OpenAI (ChatGPT)?

Yes. Select "GPTBot" or "ChatGPT-User" from the User Agent dropdown to test if your rules correctly block AI crawlers from accessing your content.

What happens if the robots.txt file is missing?

If the site returns a 404 for `robots.txt`, search engines assume that **all** URLs are allowed to be crawled. Our tool will mark all URLs as "Allowed" in this case.

Why Validate Robots.txt?

Prevent Blocking

Ensure your most important money pages aren't accidentally disallowed. A single misplaced character can de-index your entire site.

Security Audit

Check if you are correctly blocking sensitive admin areas, staging environments, or internal search result pages from public indexing.

Crawl Budget

Optimize how bots spend time on your site. Disallowing low-value generated pages helps Google focus on your quality content.

Migration Safety

Verify your rules after moving to a new domain or changing URL structures to prevent accidental de-indexing during migrations.
