🔍 1. What Is Robots.txt?

The robots.txt file is a simple text file placed in the root directory of your website (for example: https://www.vijayreddy.in/robots.txt).

It provides instructions to search engine crawlers (bots) about which pages, files, or sections of your website they are allowed or not allowed to crawl.

💡 Example:

User-agent: *
Disallow: /admin/
Allow: /blog/

This means:

• All crawlers (User-agent: *)
• Are not allowed to crawl the /admin/ directory
• Are allowed to crawl the /blog/ section

It’s like a set of rules for search engines — guiding them to the right content while keeping sensitive areas private.

🧠 2. Why Robots.txt Is Important for SEO

Although robots.txt doesn’t directly affect rankings, it plays a vital role in SEO performance.

Here’s why it matters 👇

✅ 1. Controls Crawl Budget

Search engines allocate a certain crawl budget to every website.
By disallowing unimportant or duplicate pages (like admin pages or login pages), you help Google focus on your important content.

✅ 2. Prevents Indexing of Sensitive Pages

You can stop search engines from accessing private or duplicate content — like internal dashboards, thank-you pages, or test folders.

✅ 3. Improves Server Efficiency

When bots avoid unnecessary pages, your server performs better — which helps your website load faster and handle traffic efficiently.

✅ 4. Helps Organize Website Crawling

You can control which areas of your site are open to crawlers and which are not — improving overall site structure and crawl efficiency.

🏗️ 3. How Robots.txt Works

Search engines like Google, Bing, or Yahoo send bots (crawlers) to visit your website.

When a crawler visits, it first looks for the robots.txt file in your site’s root directory.

🔁 The Process:

1. 🕵️ Crawler requests https://www.yourdomain.com/robots.txt
2. 📜 Reads the rules written in the file
3. ✅ Crawls only the allowed URLs
4. 🚫 Skips the URLs listed under “Disallow”

It’s important to note:
❗ Robots.txt only controls crawling, not indexing.
Even if a page is disallowed, it may still appear in search results if other pages link to it. To prevent indexing, use the noindex meta tag instead.

📁 4. Where to Find the Robots.txt File

Your robots.txt file is always located at the root of your domain.

📍 Example URLs:

• https://www.vijayreddy.in/robots.txt
• https://www.example.com/robots.txt

If you can’t find it, that means your site doesn’t have one yet — but don’t worry, you can easily create it.

✍️ 5. How to Create a Robots.txt File

Creating a robots.txt file is super simple. You can use any text editor like Notepad, VS Code, or even an online generator.

🪜 Steps to Create:

1. Open a plain text editor.
2. Write your crawl instructions (we’ll show syntax next).
3. Save it as robots.txt.
4. Upload it to your website’s root directory using FTP or your hosting control panel.

🧾 6. Robots.txt Syntax Explained

Let’s understand the basic commands or directives used inside robots.txt:

🧩 Example 1 – Basic Syntax

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

👉 Blocks all bots from /admin/ but allows them to crawl everything else.

🧩 Example 2 – Targeting Specific Bots

User-agent: Googlebot
Disallow: /private-data/

User-agent: Bingbot
Disallow: /testing/

👉 Googlebot and Bingbot follow different rules.

🧩 Example 3 – Adding Sitemap

User-agent: *
Disallow:
Sitemap: https://www.vijayreddy.in/sitemap.xml

👉 Always include your sitemap — it helps bots discover pages efficiently.

🚫 7. Common Directives in Robots.txt

Let’s break down the most useful robots.txt directives for SEO 👇

🧱 User-agent

Specifies which crawler the rule applies to.
Use * to apply to all bots.

🚷 Disallow

Blocks bots from accessing certain pages or directories.

Example:

✅ Allow

Used to override a disallow rule — allowing certain pages or folders.

Example:

Disallow: /images/
Allow: /images/public/

🗺️ Sitemap

Tells crawlers where to find your sitemap.

Example:

Sitemap: https://www.vijayreddy.in/sitemap.xml

🧠 9. Robots.txt Best Practices for SEO

Follow these SEO-friendly tips to make the most out of your robots.txt file 👇

💡 1. Always Allow Important Content

Ensure your blog, product, and service pages are crawlable.

💡 2. Block Duplicate or Thin Pages

Avoid crawling login pages, test folders, or duplicate parameter URLs.

💡 3. Include Sitemap URL

Add your sitemap at the bottom of your robots.txt file.

💡 4. Use Wildcards (*) and Dollar Sign ($) Wisely

Example:

Disallow: /*?ref=
Disallow: /temp$

👉 This blocks URLs with tracking parameters or those ending with /temp.

💡 5. Keep It Simple

Avoid complex rules — clarity reduces errors.

💡 6. Test Before Publishing

Always test your robots.txt file before uploading it live.

⚠️ 10. Common Robots.txt Mistakes

Even small errors in your robots.txt file can hurt your SEO.
Here are common mistakes to watch out for 🚨

❌ 1. Blocking the Entire Site by Mistake

User-agent: *
Disallow: /

👉 This stops all bots from crawling your website!

❌ 2. Forgetting to Allow Important Directories

Make sure your main content folders are accessible.

❌ 3. Assuming It Blocks Indexing

Remember: Disallow prevents crawling, not indexing.
Use noindex meta tag or header to stop indexing.

❌ 4. Syntax Errors

Even missing a colon (:) or space can make the file invalid.

❌ 5. Not Updating After Site Changes

If your site structure changes, update robots.txt accordingly.
