Add Blogger Custom Robots Text File

Search engine bots like Googlebot (Web Crawling Robot of Google) needs some guidelines on how they have to crawl and index our blog. We can prevent some non important pages labels pages from indexing in Google to protect our blog from duplicate content issues. Got confused? Check out below tutorial which will clear all of your confusions.


Custom robots.txt is a way for you to instruct the search engine that you don’t want it to crawl certain pages of your blog (“crawl” means that crawlers, like Googlebot, go through your content, and index it so that other people can find it when they search for it). For example, let’s say there are parts of your blog that have information you would rather not promote, either for personal reasons or because it doesn’t represent the general theme of your blog -- this is where you can clarify these restrictions.
However, keep in mind that other sites may have linked to the pages that you’ve decided to restrict. Further, Google may index your page if we discover it by following a link from someone else's site. To display it in search results, Google will need to display a title of some kind and because we won't have access to any of your page content, we will rely on off-page content such as anchor text from other sites. (To truly block a URL from being indexed, you can use meta tags.)

What is Robots.txt?

Robots.txt is a text file which contains few lines of simple code. It is saved on the website or blog’s server which instruct the web crawlers to how to index and crawl your blog in the search results. That means you can restrict any web page on your blog from web crawlers so that it can’t get indexed in search engines like your blog labels page, your demo page or any other pages that are not as important to get indexed. Always remember that search crawlers scan the robots.txt file before crawling any web page.
Each blog hosted on blogger have its default robots.txt file which is something look like this:
User-agent: Mediapartners-Google
Disallow:
User-agent: *
Disallow: /search
Allow: /
Sitemap: http://example.blogspot.com/feeds/posts/default?orderby=UPDATED

Explanation

This code is divided into three sections. Let’s first study each of them after that we will learn how to add custom robots.txt file in blogspot blogs.
1.     User-agent: Mediapartners-Google
This code is for Google Adsense robots which help them to serve better ads on your blog. Either you are using Google Adsense on your blog or not simply leave it as it is.
  • User-agent: *
This is for all robots marked with asterisk (*). In default settings our blog’s labels links are restricted to indexed by search crawlers that means the web crawlers will not index our labels page links because of below code.
Disallow: /search
That means the links having keyword search just after the domain name will be ignored. See below example which is a link of label page named SEO.
http://www. yourblogname.blogspot.com /search/label/SEO
And if we remove Disallow: /search from the above code then crawlers will access our entire blog to index and crawl all of its content and web pages.
Here Allow: / refers to the Homepage that means web crawlers can crawl and index our blog’s homepage.

Disallow Particular Post

Now suppose if we want to exclude a particular post from indexing then we can add below lines in the code.
Disallow: /yyyy/mm/post-url.html
Here yyyy and mm refers to the publishing year and month of the post respectively. For example if we have published a post in year 2013 in month of March then we have to use below format.
Disallow: /2013/03/post-url.html
To make this task easy, you can simply copy the post URL and remove the blog name from the beginning.

Disallow Particular Page

If we need to disallow a particular page then we can use the same method as above. Simply copy the page URL and remove blog address from it which will something look like this:
Disallow: /p/page-url.html
  • Sitemap: http://example.blogspot.com/feeds/posts/default?orderby=UPDATED
This code refers to the sitemap of our blog. By adding sitemap link here we are simply optimizing our blog’s crawling rate. Means whenever the web crawlers scan our robots.txt file they will find a path to our sitemap where all the links of our published posts present. Web crawlers will find it easy to crawl all of our posts. Hence, there are better chances that web crawlers crawl all of our blog posts without ignoring a single one.
Note: This sitemap will only tell the web crawlers about the recent 25 posts. If you want to increase the number of link in your sitemap then replace default sitemap with below one. It will work for first 500 recent posts


Sitemap: http://yourblogname.blogspot.com/atom.xml?redirect=false&start-index=1&max-results=500
If you have more than 500 published posts in your blog then you can use two sitemaps like below:
Sitemap: http://example.blogspot.com/atom.xml?redirect=false&start-index=1&max-results=500
Sitemap: http://example.blogspot.com/atom.xml?redirect=false&start-index=500&max-results=1000
