Blogger Custom Robots.txt Generator: Build a Clean Robots.txt File

Here's a situation almost every Blogger user runs into sooner or later. You open Settings, scroll to "Crawlers and indexing," see a box called Custom robots.txt, and freeze. It looks technical, one wrong line could hurt your site, and half the tutorials online tell you to paste something different.

The free Blogger Custom Robots.txt Generator removes the guesswork. You type your website address, tick the options you want, and get a ready-to-paste file. This guide walks through what the tool does, what each option means, and how to use the result safely.

First, What Is Robots.txt and Why Should You Care?

Robots.txt is a small text file at the root of your site, always found at yourdomain.com/robots.txt. Search engine crawlers read it before exploring your pages. It tells them where they're welcome and where they should not waste time.

For a Blogger site this matters because the platform creates plenty of automatic pages: internal search results, label pages and archives. These pages mostly repeat content from your real posts. A good robots.txt file nudges crawlers toward your articles and away from the clutter. It also tells them where your sitemap is, so new posts are found faster.

One thing to keep in mind: robots.txt is a request, not a lock. Well-behaved crawlers follow it, but it doesn't hide anything and it isn't a security feature.

Meet the Tool: What You Get

The generator is deliberately simple. There are only a few things on the page:

• A website URL box where you enter your blog's address
• An AdSense crawler checkbox, switched on by default
• A static pages sitemap checkbox, switched off by default
• A Generate button that builds the file
• A Copy button that puts the finished code on your clipboard

Everything happens in your browser, so you can try different options as many times as you like.

How to Use the Generator Step by Step

1. Open the Custom Robots.txt Generator.
2. Type your website address, such as https://www.example.com or https://yourblog.blogspot.com.
3. Decide whether to keep the AdSense crawler option on. If you show ads or plan to, leave it checked.
4. Tick the static pages sitemap option if your blog has pages like About, Contact or Privacy Policy.
5. Click Generate Robots.txt.
6. Click Copy Code.

You don't have to be precise with the address. If you forget https://, the tool adds it. If you paste a full post link by mistake, it keeps only the main domain. That's handy, because the sitemap lines in robots.txt must use your site's root address, not a deep link.

Understanding the Two Options

Allow the Google AdSense crawler

AdSense uses its own crawler, named Mediapartners-Google, to read your pages and work out which ads fit your content. When this option is on, the file includes a rule saying that crawler is not blocked from anything. The tool recommends keeping it enabled, and I agree. Even if you haven't joined AdSense yet, having the rule there does no harm and saves you from editing the file later.

Add the static pages sitemap

Blogger builds one sitemap for your posts and a separate one for your static pages. Checking this box adds a second sitemap line pointing to sitemap-pages.xml, so crawlers can find pages like About and Contact too. If you have created static pages, turn it on. If your blog contains only posts, you can leave it off.

What the Output Looks Like

With both options on and the address https://www.example.com, you get this:

User-agent: Mediapartners-Google
Disallow:

User-agent: *
Disallow: /search
Allow: /

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

If you turn both options off, the file is shorter:

User-agent: *
Disallow: /search
Allow: /

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

Let's break down the important line, Disallow: /search. On Blogger, internal search results and label pages sit under the /search path. Blocking it keeps crawlers away from those repeated listings. Allow: / then confirms that everything else, including your homepage, posts and pages, stays open.

How to Add the File to Blogger

1. Open your Blogger dashboard and click Settings.
2. Scroll to Crawlers and indexing.
3. Switch on Enable custom robots.txt.
4. Click Custom robots.txt, paste the code you copied, and save.
5. Visit yourdomain.com/robots.txt in a browser tab to confirm the new text is live.

That last step takes ten seconds and catches most mistakes, such as a typo in the domain or a paste that didn't save.

Why Not Just Write It by Hand?

You can, and for a single blog it only takes a minute. But small errors in this file are surprisingly easy to make: a missing https://, a sitemap line pointing to the old blogspot address after moving to a custom domain, or a stray slash. The worst one is Disallow: / by itself. That tells every crawler to stay away from your entire site. A generator builds each line the same way every time, so you avoid those slips.

Mistakes to Avoid

Believing robots.txt removes pages from Google. It controls crawling, not indexing. If you want a page out of search results, use a noindex tag or the removal tool in Google Search Console. Also remember that a page blocked in robots.txt can't be read for a noindex tag.

Forgetting to update after a domain change. If you move from a blogspot address to a custom domain, generate the file again with your new address.

Blocking too much. Don't add extra Disallow lines unless you know exactly why. The default pattern is safe for most blogs.

Putting secrets in the file. Robots.txt is public. Anyone can open it, so never list private areas there.

Never checking the result. After you save, test the live file and look at the robots.txt report in Google Search Console for any problems.

Does Robots.txt Help with AdSense Approval?

Not by itself. AdSense reviews the quality of your content and your overall site: original articles, clear navigation, and trust pages. What robots.txt does is make sure nothing technical gets in the way. If crawlers can't reach your pages, they can't evaluate them.

So once your robots.txt is in place, spend your time on content and the basics every site needs. If you haven't added a Privacy Policy, Terms of Service and Disclaimer yet, our free Policy Generator can give you drafts to edit and publish.

A Simple Routine to Keep Your Blog Healthy

• Generate and install your robots.txt once, then recheck it if you change domains or platforms.
• Submit your sitemap in Google Search Console.
• Review the coverage and indexing reports every month or so.
• Keep your titles and descriptions strong. Our SEO Meta Tag Generator can help with that.

Frequently Asked Questions

Is the Blogger Custom Robots.txt Generator free?

Yes. It's free, needs no account and runs right in your browser.

Do I need to include https:// in the address?

No. If you leave it out, the tool adds it for you. It also trims anything after the domain name.

For most people, yes. It keeps the ad crawler unblocked and costs you nothing, even if you aren't using AdSense yet.

When should I add the static pages sitemap?

Whenever you have static pages such as About, Contact or Privacy Policy. It helps crawlers discover them.

Does it work with a custom domain?

Yes. Enter your custom domain, for example https://www.example.com, and the sitemap lines will use it.

Will this guarantee better rankings?

No. It helps search engines crawl your site efficiently, which is a good foundation, but rankings still depend mainly on the quality and usefulness of your content.

How do I go back to the default file?

In Blogger's Crawlers and indexing settings, turn off Enable custom robots.txt. Blogger will then use its default file again.

Final Thoughts

A robots.txt file is a small piece of housekeeping, but it's one that quietly supports everything else you do for your blog.
