Mastering Robots.txt: Guide to Controlling Search Engine Access

Introduction

Have you ever heard about a robots.txt file and wondered what it is? Well, it’s like a doorman for your website, telling search engines which parts they can visit and which they should skip. Let’s dive into this simple but crucial part of website management!

What is a Robots.txt File?

A robots.txt file is a small text file that lives in the root directory of your website. Think of it as a set of instructions for search engine robots (or ‘bots’) like those used by Google and Bing. These bots are like digital explorers that scan the web, but sometimes, you might not want them to scan every part of your site. That’s where the robots.txt file comes in.

Google and Bing Bots

Google has various bots for different tasks – some check the quality of ads, others look for images or news content. Bing has its bots too, like Bingbot, which helps it understand what’s on your site. These bots usually follow links from other websites or sitemaps that you submit to them.

How Does Robots.txt Work?

Let’s say you have a part of your website that you don’t want these bots to scan. You can use the robots.txt file to tell them to stay away from that area. Here’s an easy way to understand it:

Blocking Specific Areas: If you have a section on your site, like “example-subfolder,” and you don’t want Google or Bing’s bots to go there, your robots.txt file would have lines like:
- User-agent: Googlebot
- Disallow: /example-subfolder/
- User-agent: Bingbot
- Disallow: /example-subfolder/

If you decide that you do not want the search engines to crawl your website then you will have to add a robots.txt file to your website.

User-agent: Googlebot Disallow: /example-subfolder/
User-agent: Bingbot Disallow: /example-subfolder/
Sitemap: https://yourwebsite.con/sitemap.xml

Adding Your Sitemap: You can also use robots.txt to point bots to your sitemap, which is like a map of your site. It helps bots find all the good stuff you want them to see.
- Sitemap: https://yourwebsite.com/sitemap.xml

What You Shouldn’t Do

Don’t Put Sensitive Info: Since anyone can read your robots.txt file (just by adding /robots.txt to your website’s URL), don’t put any secret information there.
Be Careful with Blocking: Blocking parts of your site can be helpful, but if you block too much, it might affect how well your site shows up in search results.

Advanced Tips

Blocking Specific File Types: If you don’t want certain file types (like PDFs) to be scanned, you can specify that.
- Disallow: /*.pdf$
Delaying Crawling: You can even tell bots to slow down a bit when scanning your site. This is useful if you’re worried about your site’s performance. But remember, not all search engines follow this rule.
- Crawl-delay: 10 (this means 10 seconds)

Block all crawlers from all content.

User-agent: * Disallow: /

Allowing all crawlers to all content

User-agent: * Disallow:

Blocking Googlebot from access a specific file on your website.

User-agent: Googlebot Disallow: /subfolder/

Blocking Googlebot from a specific page on your website.

User-agent: Googlebot Disallow: /subfolder/block-page.html

Do not allow specific file types from being accessed.

User-agent: *
Disallow: /*.pdf$

Linking your sitemap in your robots.txt file. Usually at the bottom.

User-agent: *
Sitemap: https://pagedart.com/sitemap.xml

Delaying the crawling of your website. This delays it for 10 seconds and you can enter 1 to 30 seconds. Google does not follow this rule.

User-agent: *
Crawl-delay: 10

Conclusion

The robots.txt file is a powerful tool in your website management toolkit. It helps you guide search engine bots through your site, making sure they only access the areas you want them to. Remember, a well-configured robots.txt file can make a big difference in how search engines understand and display your site!
