What Should a robots.txt File Include for a Small Site?

For a small site, what to include in robots.txt is usually simple: a rule for all crawlers, only the specific paths you want them not to crawl, and your sitemap URL. If you have no areas that need crawling limits, a minimal file—or no file at all—may be enough.

Robots.txt is a set of instructions for automated crawlers, not a security barrier. The goal is to guide compliant search engine bots without accidentally hiding useful parts of your site. Here is what to put in the file, what to avoid, and how to check it.

What to include in robots.txt for a small site

A basic robots.txt file can contain two types of lines: crawler rules and an optional sitemap reference. A common starting point looks like this:

User-agent: *
Disallow:

Sitemap: https://www.example.com/sitemap.xml

User-agent: * applies the following rule to all crawlers that follow the Robots Exclusion Protocol. Disallow: with nothing after the colon means no paths are disallowed by that rule. The Sitemap line gives crawlers the full address of your sitemap, if you have one.

If you have a specific directory you do not want crawlers to request, add a path after Disallow:

User-agent: *
Disallow: /members-only/

Sitemap: https://www.example.com/sitemap.xml

Replace the example domain and path with your own. Do not copy a restriction just because it appears in another site's file; the right rule depends on your site and its purpose.

What the main robots.txt directives mean

Robots.txt behavior can vary between crawlers, especially for less common syntax. Keep rules straightforward and consult the documentation for a crawler if you rely on crawler-specific directives.

How to decide what to disallow

Start by asking whether a path should be crawled, not whether you would prefer it to stay private. A robots.txt rule is a request to compliant bots. It does not require a crawler to obey, and a blocked URL may still be discovered through links or shown in search results without a page description.

Do not use robots.txt to protect passwords, customer information, unpublished documents, or any other sensitive content. Restrict access with authentication or server-side permissions instead. The file itself is public, and listing a path can reveal that the path exists.

Possible candidates for a crawl restriction might include a private-use area that is already access-controlled or a page that creates an unlimited set of crawlable URL variations. These situations need care: blocking a URL does not remove the underlying content, and a crawler cannot read a blocked page to understand a removal instruction on that page.

For a typical small business or personal site, public pages such as the homepage, service pages, articles, and product pages should generally remain crawlable if you want search engines to find them. Avoid blocking a whole site with Disallow: / unless you intentionally want to prevent compliant crawlers from crawling every path.

What not to put in the file

• Passwords or secrets: Never include credentials, API keys, or confidential notes. Treat the file as public.
• Rules copied without checking: A rule intended for another platform or site can block pages you need crawled.
• Private URLs as a privacy measure: Use access controls, not crawler instructions, to keep content confidential.
• Broad blocks on site assets: Blocking CSS, JavaScript, or images can make it harder for crawlers to understand how pages work or look.
• Unnecessary complexity: Many overlapping rules are harder to maintain and easier to misconfigure than a short, clear file.

Also, robots.txt does not replace a page-level noindex instruction. If you need a page excluded from search results, use an appropriate indexing control and make sure the crawler can access the page to see it. The right approach depends on your platform and the outcome you want.

How to create and check a robots.txt file

1. List the site's important public pages. Identify the pages and assets you want crawlers to access, along with any paths that genuinely need a crawling restriction.
2. Find your sitemap URL. If your website generates a sitemap, use its exact public address. If you do not have one, do not invent a URL; you can add it later.
3. Write the smallest useful set of rules. Start with a general User-agent rule and add only the Disallow paths you need. Include a Sitemap line when applicable.
4. Save the file as robots.txt. Use plain text and place it at the root of the relevant host—for example, https://www.example.com/robots.txt. A file in a subfolder does not control the whole site.
5. Check the live version. Open the URL in a browser and confirm that the file loads, the domain is right, and the instructions match your intended setup. Check important pages and assets against the rules.
6. Review after site changes. Revisit the file when you add a private area, change URL patterns, move your sitemap, or migrate your site.

If you want help formatting a straightforward file, use the Robots.txt Generator to create a properly structured starting point. Review the result against your actual site before publishing; a generator cannot decide which pages should be crawlable for you.

Common small-site examples

A simple brochure site: If all pages are public and crawlable, a general allow-all rule and sitemap reference may be sufficient. Some owners also choose not to publish a robots.txt file when they have no special crawler instructions; a sitemap can still be submitted through other supported methods.

A site with a private member area: Keep the member area protected by login. A Disallow rule may reduce routine crawling of its paths, but it is not the protection itself. Do not assume the rule conceals the area.

A site being prepared before launch: Avoid relying on robots.txt alone to keep a staging site out of public view. Use a password or another access restriction. When the live site is ready, check that no broad disallow rule was accidentally carried over.

A site with search or filter URLs: Some sites generate many URL combinations. Before blocking them, understand whether those URLs contain useful, distinct content and how your platform handles indexing. A broad pattern can unintentionally match valuable pages.

Quick checklist before publishing

• The file is named robots.txt and is available at the root of the correct host.
• Each rule is intentional and uses the path you mean to target.
• Important public pages and required assets are not blocked accidentally.
• The sitemap URL, if included, is complete and points to the current sitemap.
• No sensitive information is included, and private content is protected separately.
• The live file matches your intended behavior after any site migration or redesign.

For most small sites, a good robots.txt file is short, readable, and conservative. Include only crawler instructions you understand, use a sitemap reference when you have a sitemap, and keep access control separate from crawl management.

Frequently asked questions

Does every small website need a robots.txt file?

No. If you have no special crawling instructions, you may not need one. If you do publish one, make sure it is available at the root of the correct host.

Can robots.txt keep a page out of Google search results?

Not reliably. It controls crawling requests from compliant bots, but a blocked URL may still be discovered and shown. Use appropriate indexing controls for search-result removal, and do not treat robots.txt as a privacy tool.

Should I add my sitemap to robots.txt?

You can include its full URL in a Sitemap line. This helps crawlers discover the sitemap, but it does not guarantee crawling or indexing.

What does Disallow: / do?

It asks crawlers covered by that rule not to crawl any path on the host. Use it only when that broad result is intentional, and check carefully before publishing.

Where should robots.txt be located?

At the root of the relevant host, such as https://example.com/robots.txt. A file under a subfolder does not set rules for the entire site.
