What is WordPress Robots.txt and why should we use it?

Robots.txt file helps search engine robots to direct which part to crawl and which part to avoid. When Search bot or spider of Search Engine comes to your site and wants to index your site, they follow Robots.txt file first. Search bot or spider follows this files direction for index or no index any page of your website.

If you are using WordPress, you will find Robots.txt file in the root of your WordPress installation. For static websites, if you have created one or you developer has created one, you will find it under your root folder. If you can’t simply create a new notepad file and name it as Robots.txt and upload it into Root directory of your domain using FTP. Here is PJERA Robots txt file and you can see the content and it’s the location at the root of the domain.

How to make  robots.txt file?

As I mentioned earlier, Robots.txt is a general text file. So, if you don’t have this file on your website, open any text editor as you like ( as the example: Notepad) and make Robots.txt file made with one or more records. Every record bears important information for search engine. Example:

User-agent: googlebot

Disallow: /cgi-bin

If these lines write on Robots.txt file it’s allowed Google bot for index every page of your site. But cgi-bin  folder of root directory doesn’t allow for indexing. That means Google bot won’t index cgi-bin  folder.

By using Disallow option, you can restrict any search bot or spider for indexing any page or folder. There are many sites who use no index in Archive folder or page for not making duplicate content.

Where Can You Get names of Search bot?

You can get it in your website’s log, but if you want lots of visitors from the Search engine you should allow every search bot. That means every search bot will index your site. You can write User-agent: *  for allow every search bot. Example:

User-agent: *

Disallow: /cgi-bin

That’s why every search bot index your Website.

What You Shouldn’t do?

1. Don’t use comments in Robots.txt file.

2. Don’t keep the space at the beginning of any line and don’t make ordinary space in the file. Example:

Bad Practice:

   User-agent: *

Dis allow: /support

Good Practice:

User-agent: *

Disallow: /support

3. Don’t change rules of command.

Bad Practice:

Disallow: /support

User-agent: *

Good Practice:

User-agent: *

Disallow: /support

4. If you want no index, more than one directory or page don’t write along with these names:

Bad Practice:

User-agent: *

Disallow: /support /cgi-bin /images/

Good Practice:

User-agent: *

Disallow: /support

Disallow: /cgi-bin

Disallow: /images

5. Use capital and small letter properly. As the example, you want no index “Download” directory but write “download” on Robots.txt file. It makes miss understand for search bot.

6. If you want index all page and directory of your site write:

User-agent: *


7. But if you want no index for all page and directory of you site write:

User-agent: *

Disallow: /

After editing Robots.txt file upload via any FTP software on Root or Home Directory of your site.

Robots.Txt for WordPress:

You can either edit your WordPress Robots.txt file by logging into your FTP account of the server or you can use plugin like Robots meta to edit robots.txt file from WordPress dashboard. There are few things, which you should add in your robots.txt file along with your sitemap URL. Adding sitemap URL helps search engine bots to find your sitemap file and thus faster indexing of pages.

Here is a sample Robots.txt file for any domain. In sitemap, replace the Sitemap URL with your blog URL:

sitemap: https://www.pjera.com/sitemap.xml

User-agent:  *
# disallow all files in these directories
Disallow: /cgi-bin/
Disallow: /wp-admin/
Disallow: /archives/
disallow: /*?*
Disallow: *?replytocom
Disallow: /comments/feed/
User-agent: Mediapartners-Google*
Allow: /
User-agent: Googlebot-Image
Allow: /wp-content/uploads/

User-agent: Adsbot-Google
Allow: /

User-agent: Googlebot-Mobile
Allow: /

How to make sure no content is affected by new Robots.txt file?

So now you have made some changes into your Robots.txt file, and it’s time to check if any of your content is impacted by updating robots.txt file. You can use Google Webmaster tool ‘Fetch as bot tool’ to see if your content can be accessed by Robots.txt file or not.
