How to Block Bot Traffic in Google Analytics 4

Google Analytics is a crucial tool for website owners and digital marketers to track and analyze user behavior on their websites.

One common concern when using Google Analytics is dealing with bot traffic, which can spoil your data and provide inaccurate insights.

With the transition from Universal Analytics (UA) to Google Analytics 4 (GA4) on July 1, 2023, there have been changes in how bot traffic is handled. In this article, I will explain to you how blocking bot traffic is handled in Google Analytics 4.

What is Bot Traffic?

Bot traffic refers to web traffic generated by automated software programs that visit websites for various purposes.

Some bots, like search engine crawlers, are beneficial as they index web content for search engines like Google.

However, other bots can be malicious and negatively impact your website's analytics by inflating pageviews, sessions, and engagement metrics.

Google Analytics 4 and Bot Traffic

With the introduction of GA4, Google has made significant changes in how bot traffic is handled compared to Universal Analytics.

In GA4 properties, traffic from known bots and spiders is automatically excluded. This means that your analytics data will, to a large extent, not include events generated by known bots. This change is aimed at providing more accurate and relevant data to users.

How Known Bot Traffic Exclusion Works

Known bot traffic exclusion in Google Analytics 4 is achieved through a combination of Google's own research and the International Spiders and Bots List maintained by the Interactive Advertising Bureau (IAB).

This list is regularly updated to include new bots and spiders, ensuring that GA4 can identify and exclude traffic from the most common ones.

Can You Disable Known Bot Traffic Exclusion?

As of now, Google does not provide an option to disable the automatic exclusion of known bot traffic in GA4 properties. This means that you cannot turn off this feature even if you want to include bot traffic in your analytics data.

Checking Excluded Bot Traffic

Google Analytics 4 does not provide a feature to view how much-known bot traffic was excluded. Google's intention here is to simplify analytics reporting by automatically removing irrelevant data.

Additional Tips for Dealing with Bot Traffic

While Google Analytics 4 takes care of known bot traffic, there may still be some unidentified bots or unwanted traffic that you want to block. Here are some additional tips to consider:

  1. Use a Website Firewall: Implement a website firewall that can detect and block suspicious traffic, including bots. Services like Cloudflare and Sucuri offer excellent bot protection.
  2. Set Up Filters: Although GA4 does automatic known bot traffic exclusion, you can create filters in your GA4 view settings to further refine your data and exclude specific user agents or IP addresses associated with unwanted bot traffic.
  3. Regularly Review Data: Keep an eye on your analytics data and investigate any anomalies. If you notice unusual spikes in traffic or engagement metrics, it could be a sign of bot activity that needs further investigation.
  4. Monitor User Agents: Monitor the user agents in your traffic reports. Bots often have unique user agents that can help you identify and block them.


Google Analytics 4 has introduced automated known bot traffic exclusion, simplifying the process of blocking unwanted bot traffic.

While this change helps provide more accurate analytics data, it's essential to be aware that not all bot traffic may be excluded. Therefore, implementing additional security measures and regularly monitoring your data can further enhance your ability to manage bot traffic effectively.
