How Does The Robots.txt File Work?

By crawling the pages on your website, the search engines will index it on the web. During crawling, search engines discover and follow the links. As a result, they reach site A to site B to site c, etc. But the search engine, before visiting any pages on a domain, opens the robots.txt file of that domain.

By opening the robots.txt file of the domain, they can learn which URLs on your site are allowed to visit and which are not. Then the search engine index or crawls only the accessible URLs.

Why Do You Need The Robots.txt File For Your WordPress Site?

The search engines will index and crawl your website even if your site doesn’t have the robots.txt file. But now the question is why you require this text file for your site. The thing is, without a robots.txt file, search engines will index your site. But you will fail to tell the search engines which folders or pages they should not index or crawl.

If you are starting your blog for the first time, this will have less impact on your website. Usually, the new site has less content. And not having the robots.txt file creates less effect. But when your site grows and there is a lot of content, you should write it. It will help you to have better control over your website.

For each website, the search bots have a specific crawl quota. It means that the search bots crawl a particular number of pages during the crawl session. If they don’t finish your site’s all pages crawling, they will come back again. And in the next session, the search engine starts crawling your site again. This process can slow down the indexing rate of your website.

So, with the help of robots.txt, you can fix this problem and disallow the search bot to crawl your site’s unnecessary pages. Indexing the plugin files, WordPress admin pages, and themes folder is not necessary. Save your site’s crawl quota by disallowing the crawling of unimportant pages.

As a result, search engines will index more pages on your site by crawling them more quickly. So, the most important reason for using robots.txt is to stop search engines from crawling your website’s unnecessary pages.

However, hiding your content from the general public is not the safest way. But using robots.txt will prevent the appearance of content in the search results.
