What is GoogleBot?

GoogleBot is part of Google’s search engine technology. It basically crawls the web, identifying every service and site connected to the open web. It takes in as much information as it can and feeds it to Google index. So, you can thank the Googlebot for accumulating websites and information that is displayed when you “Google” something.

To evaluate a website’s performance on various devices, Googlebot identifies itself as certain types of device. From smartphones to desktop computers, the crawler (sometimes called ‘spider’) uses a “user-agent” string that includes some of the basic capabilities of a device.

The job of Google index is to accept web pages from Googlebot and rank them.

How to make sure that your site is crawled by Google Bot


Since Google index updates results through Googlebot, it is essential that it can see your pages. To get an idea of what Google sees from your site do the following Google search…

  • By prefixing “site:” in front of your domain name you will be asking Google to list the pages it has indexed for your site.

Just because Googlebot can see your pages doesn’t mean that Google got a perfect picture of what those pages are. It is also very important to ensure that Google is seeing your links and content correctly. For that let’s check How Googlebot “sees” a webpage:

  • Googlebot does not see full web pages; it only sees some individual components of that page.
  • It accesses only CSS, HTML, JS and image components. Then it forwards them to the Google index.

There are many cases where Google bot might not be able to access web pages. Below are a few common ones.

  • Page links not readable or incorrect
  • Resource blocked by robots.txt
  • Bad HTML or coding errors
  • Over dependence on Flash or other technology that web crawlers may have issues with
  • Overly complicated dynamic links

Googlebot follows instructions it receives through robots.txt standards and even has advanced ways to control it.

Some ways you can control Google bot are:

  • Including robot instructions in the metadata of your web pages
  • Using a robots.txt file
  • Including robot instructions in your headers
  • Using sitemaps
  • Using Google search console

Like every other resource, Google has its Pros and Cons:


– It can quickly create a list of links that come from the Web.

– It re-crawls popular dynamic web pages to keep the index current.


– It only follows HREF and SRC links.

– Some pages may take longer to get found, so crawling may occur once a month.

– It takes up an enormous amount of bandwidth.

– It must be programmed or set up to function properly.
