What is an adblock?

by SW Team

In the digital age in which we live, online advertising has become a constant that can become annoying to understand, let's imagine the following situation. You are watching your favorite movie on the Internet, on YouTube or another website, and it is interrupted by a small ad for 10 to 30 seconds. Of course, this type of advertising is much shorter than what we see on TV, but it still spoils the audiovisual experience. We also constantly encounter advertising messages when reading articles, news or searching for information on the Internet. For these annoyances, Adblocks (a kind of magic wand that blocks ads and nothing else will interfere with your browsing experience) were developed.

What is an adblock?

An Adblock, or ad blocker, is a tool designed to eliminate or reduce the amount of advertising displayed while surfing the Internet. These programs, browser extensions or applications work by filtering content before it is displayed on our screen, blocking elements considered to be advertisements.

How does an Adblock work?

Ad blockers work on the basis of regular lists, called filter lists, which determine what content to block or hide and what content to allow to be displayed on the pages you visit. These lists are a simple list of URLs that are either on the allowed download list or the blocked list.

When you visit a site, the ad blocker instantly checks to see if it is on one of these filter lists. If this is the case, then the request for external content is blocked and the ad is not loaded on the page. Basically, ad blocking technology is a set of rules set in these filter lists that determine what content to block or not block on the pages you visit.

Filter lists are usually maintained by communities of volunteer contributors.

Some of the most popular filter lists include EasyList and Fanboy's List.


Advantages of Using Adblock

Cleaner browsing experience: By removing ads, web pages look less cluttered and the user experience is significantly improved.

Faster loading speed: Ads can slow down the loading of web pages. By blocking them, pages tend to load faster.

Protection against malware: Some ads can be vectors for malware or spyware. Using an Adblock can reduce the risk of being infected by these threats.

Data savings: Ads consume bandwidth. By blocking them, users can save on data usage, which is especially beneficial for those browsing from mobile devices with limited data plans.

Disadvantages of Using an Adblocker

Negative impact on revenue for content creators or businesses, many websites generate revenue from advertising advertised on their websites. By blocking ads, users negate this source of revenue for websites.

Blocking non-advertising web content: In some cases, Adblocks can block content that is not strictly advertising, affecting the web content displayed to the user.

Anti-adblock notifications: Some websites detect the use of Adblocks and display notifications asking users to disable these tools to access the content, this triggers you to search for the content on another website or have to disable Adblock.
