Ad-blocker is an application to stop annoying advertisements while browsing the web or using the system in general.

This form of disturbance comes in many forms, such as banners, notifications, pop-overs, full-screen ads, and the worst of them all–auto-play videos. And while every user despises adverts, a very small percentage pays for the content they consume. So it becomes an unavoidable way of survival for the publishers and (free) app developers.

But sometimes, they overdo it, impacting browsing speed, data usage, and battery life. Besides, most ads track users across devices and platforms for targeted engagement, giving no regard for digital privacy.

That’s why our team at Geekflare has researched and made this list of ad blockers based on various factors like ethical ad blocking, browser integration, anti-tracking protection and automatic tracker blocking.

What is Ad Blocker?

An ad-blocker is a standalone application or a browser extension used to prevent ads from appearing on web pages. Depending on the specific blocker, these apps ensure a cleaner, private, and non-intrusive user experience throughout the operating system, specifically within the web browser.

Some adblocking tools can also work as anti-tracking software.

Though they sometimes overlap, ad blocking and anti-tracking are two different domains.

Importance of Adblocker for Improving Online Experience

Adblockers are important for a consistent user experience across the web. These apps stop invasive elements, such as pop-up ads, auto-play videos, ad & cookie banners, and more, from eating up the browsing space and bandwidth.

Most ad blockers can be configured to allowlist websites, which helps publishers to monetize their content. Besides, advanced adblockers also safeguard a user from malware and digital profiling (used in targeted advertisement).

How Ad Blocker Works?

Ad block applications work on the principle of filters.

Put simply, when we enter a URL, the web browser requests a number of resources from the target server, including text, images, ads, and anything else the owner has included in the web page.

Ad-blocker tools analyze the outgoing requests and use predefined filters to intercept the ones downloading ads, resulting in a cleaner and faster end-user experience.

Benefits of Ad Blocker Software

An ad-blocker software provides the 7 benefits listed below.

  1. Improved Browsing Speed: Since ad-blockers reduce the number of outgoing requests, it reduces the time the browser takes to display the webpage.
  2. Enhanced Privacy and Security: Most ads track users across devices and platforms for digital fingerprinting. Some ads also redirect users to malicious websites (a process known as malvertising) to steal their personal information. Blocking such ads helps in better online privacy and security.
  3. Better User Experience: Ads take up crucial screen space, obstructing users from consuming the content aesthetically. Some ads even take the entire screen or pop-up playing ad videos. Removing all this nuisance helps the webpage look better and keeps the user happy.
  4. Data Savings: Reducing the number of requests results in lesser data consumption, which is good for users on limited data plans.
  5. Battery Life Extension: Adblockers definitely improve the battery life. However, the magnitude of improvement depends on the total time consumed in visiting ad-riddled websites and the nature of ads served.
  6. Supporting User Choice: While ads are sometimes the only monetization option a publisher might have, inundating a user with relentless advertising serves no purpose. Moreover, tracking a user across the internet isn’t ethical at all. In such cases, ad-blockers arms users to choose which ads to see or block all of them.
  7. Increased Productivity: Using adblockers reduces page loading times and avoids distractions to boost productivity.

How to Choose the Best Ad Blocker

Choosing an ad blocker isn’t straightforward and depends on the 9 factors discussed below.

  1. Ad Blocking Requirements: Decide what you want: basic ad blocking, adblocking plus tracking prevention, or ad-blocking with anti-malware and anti-tracking capabilities.
  2. Evaluate Blocking Capabilities: Not all adblockers help you get rid of every ad. Some tools might be good at stopping banners, while others might also cover pop-up videos. So, it’s best to check the adblocker website to see what it works for. Besides, it’s important to check if they have availability on the platform of your preference.
  3. Assess Privacy Features: Check if the ad blocker has additional features, such as custom rules, anti-fingerprinting, auto-consent, and more, which can come in handy while browsing the internet. They keep a user identity anonymous and help customize the overall experience.
  4. Consider User Experience: While there is not much to look out in a adblocker user dashboard, still, the ease with which some tool inform users about ads, tracking, and else can be a differentator.
  5. Review Compatibility: Some adblockers don’t function well with other tools, such as VPNs, as they might have their own built-in ad blockers. Therefore, check out if they will be compatible with your existing applications and devices.
  6. Understand the Impact on Sites: Not only do adblockers close an important monetization avenue for websites, but they can also affect their overall functionality. So beware of the possibility of adlockers breaking web pages.
  7. Read Reviews and Testimonials: Forums like Reddit and Quora are good places to look into user testimonials about specific tools. They are generally unbiased and give crucial insights to help a user decide.
  8. Consider the Cost: Multiple good adblockers are available for free. However, some advanced features or specific applications can be reserved for paid users. Evaluate whether the extra goodies are worth the cost for your use case.
  9. Test Before You Commit: The good thing about most paid ad blockers is a free premium trial or a toned-down free version. This allows users to test a tool thoroughly before paying anything.

Impact of Ad Blocking on Content Creators

Medium and small-sized content creators have ads as one of their biggest (sometimes the only) sources of income.

Adblockers not only dry out this revenue stream, but can break certain webpages. This may appear malfunctioning to unaware users, leading to increased bounce rates, which may inflict further damage on the publisher’s online presence.

How to Install and Configure an Ad Blocker

Steps to install and configure an ad-blocker depend on the specific software, its type (browser extension or native application), and the platform (Windows, macOS, Android, etc.).

One case is installing adblocker extensions on major browsers. A user should download them from the official browser stores (e.g., Chrome web store). Afterward, it’s simply clicking on a button like Add to browser_name to use it within that browser.

Installing the native applications can involve specific steps. You should refer to the tool’s documentation or support for exact steps.
