Purpose

The robots.txt file is a simple text file stored on your blog's server that acts as a set of instructions for search engine bots (like Googlebot or Bingbot). Its primary purpose in 2026 is to tell these crawlers which parts of your Blogspot site they should or should not visit. By default, Blogger manages this automatically, but manually editing it allows you to optimize your "Crawl Budget." This ensures that search engines spend their time indexing your high-value tutorials and articles rather than wasting resources on administrative pages, search result filters, or duplicate labels that could dilute your site's authority.

Step-by-Step: Editing Your Robots.txt

1. Navigate to Settings

Open your Blogger Dashboard and click on the Settings tab in the left-hand sidebar menu.

2. Locate Crawlers and Indexing

Scroll down to the bottom of the Settings page until you find the section labeled "Crawlers and indexing."

3. Enable Custom Robots.txt

Find the toggle switch for "Enable custom robots.txt" and turn it ON. Once enabled, the "Custom robots.txt" link below it will become clickable.

4. Input Your Custom Rules

Click on "Custom robots.txt" to open a text box. For most 2026 Blogger sites, the ideal setup looks like this:

User-agent: 
Disallow: /search
Allow: /
Sitemap: https://yourdomain.com/sitemap.xml
    

Replace yourdomain.com with your actual URL. This tells all bots to ignore your internal search result pages (which are often "thin content") but allows them to crawl everything else.

5. Verify the Changes

After clicking Save, you can verify your file is live by visiting yourblog.blogspot.com/robots.txt in your browser. You should see the exact text you just entered displayed as a plain text file.

Use Case

The Content Specialist:

An author on Indexof wants to prevent search engines from indexing their "Label" pages, which often lead to duplicate content issues. They add Disallow: /search/label/ to their robots.txt file. This forces Google to focus only on the unique permalinks of their technical guides, improving their ranking for specific, high-intent keywords.

The Privacy Advocate:

A blogger uses a specific section of their site for temporary files or "drafting" notes shared with a small team. They use the Disallow command for a specific directory to ensure those private notes do not accidentally pop up in public search results.

Best Results

For the best results in 2026, do not over-block. Many beginners accidentally use Disallow: /, which tells search engines to ignore the entire site, resulting in a total loss of traffic. Only block pages that truly offer zero value to a searcher, such as /search. Additionally, always include the full link to your sitemap.xml at the bottom of the file. This helps 2026 AI-search bots discover your new content faster. After making any changes, use the Google Search Console "Robots.txt Tester" tool to ensure your new rules aren't accidentally blocking important CSS or JavaScript files that Google needs to "see" your site's layout.

FAQ

Does robots.txt stop my page from being indexed?

Not exactly. It stops bots from crawling the page. If other sites link to that page, it might still appear in search results. To completely hide a page, you should use the "Custom robots header tags" feature in Blogger instead.

Can I block specific bots like AI Scrapers?

Yes. In 2026, you can add User-agent: GPTBot followed by Disallow: / if you want to prevent specific AI models from training on your content.

How long until Google notices my new robots.txt?

Google usually checks your robots.txt file every 24 hours. You can speed this up by using the "Submit" feature in the Search Console Robots Tester.

Misconfiguring your robots.txt file can lead to your entire blog disappearing from search results. If you are unsure about a rule, it is better to leave the default Blogger settings active.
