Online advertising has become an integral part of the internet experience. However, not all ads are created equal. Some ads are intrusive, misleading, or even malicious, and can ruin the user experience. In response, many users turn to ad blockers to avoid these annoying ads. Google Chrome, one of the most popular web browsers in the world, introduced its own ad blocker in 2018. In this article, we'll explain how Google Chrome ad blocker works and what it means for users and advertisers.

What is Google Chrome's Ad Blocker?

Chrome's ad blocker is a built-in tool that blocks ads on websites that do not meet the Better Ads Standards. The Better Ads Standards are a set of guidelines created by the Coalition for Better Ads, a group of leading international trade associations and companies involved in online media. The goal of these standards is to improve the user experience by identifying and blocking the most annoying and intrusive ads.

How Does Google Chrome's Ad Blocker Work?

Google Chrome's ad blocker works in three simple steps:

Step 1: Downloading the Ad Blocker List

When a user visits a website, Google Chrome downloads a list of ad-related URLs from the Safe Browsing service. This list includes URLs that are known to serve ads that violate the Better Ads Standards.

Step 2: Evaluating Ad Requests

When a website requests an ad, Google Chrome evaluates the request against the list of ad-related URLs. If the URL matches one on the list, Chrome blocks the ad request before it can be served.

Step 3: Blocking Ads

If Google Chrome detects a violation of the Better Ads Standards, it will block the ad from being displayed on the website.

What Types of Ads Does Google Chrome Block?

Chrome ad blocker blocks three types of ads:

Intrusive Ads

Intrusive ads are ads that interrupt or obstruct the user's browsing experience. Examples of intrusive ads include pop-ups, auto-playing video ads, and large sticky ads that cover the content of the website.

Misleading Ads

Misleading ads are ads that deceive users into clicking on them. Examples of misleading ads include fake download buttons and ads that mimic system messages.

Malicious Ads

Malicious ads are ads that can harm the user's device or steal their personal information. Examples of malicious ads include ads that download malware or redirect the user to phishing sites.

How Google Chrome Ad Blocker Affects Advertisers

Chrome ad blocker has had a significant impact on the advertising industry. Advertisers who violate the Better Ads Standards may see a decrease in ad revenue, as their ads will be blocked on websites that use Google Chrome. This has led some advertisers to change their ad practices to comply with the Better Ads Standards.

Google has also introduced a program called "Funding Choices" for publishers who are affected by the ad blocker. This program allows publishers to show a customized message to users who have ad blockers enabled, asking them to either disable the ad blocker or pay for an ad-free experience.

The Future of Ad Blocking

Ad blocking has become an increasingly popular tool for users who want to avoid annoying and intrusive ads. In response, some publishers have begun using "anti-ad-blockers" to detect and prevent ad blockers from working on their websites. This has led to a cat-and-mouse game between ad blockers and anti-ad-blockers.

As for Google Chrome's ad blocker, it will likely continue to evolve and improve over time. Google has stated that it plans to expand the ad blocker to include all ads that do not meet the Better Ads Standards, not just those that are considered intrusive or misleading.


Google Chrome's ad blocker is a powerful tool for improving the user experience on the internet. By blocking annoying and intrusive ads, users can enjoy a faster and more pleasant browsing experience. Advertisers who violate the Better Ads Standards may see a decrease in ad revenue, but the industry as a whole will benefit from higher-quality ads.
