Top 10 Best Free Ad Blockers in 2021

Have you ever been browsing through the web, and suddenly you see an advertisement pop up? Or have you been trying to read an interesting article on the internet, and you see an ad placed between lines? These are annoying situations that we have all been in. There are more than a million users who use the internet for various purposes.

Let us assume that each surfer goes through five ads on a website. With this calculation, five million ads are being looked at every time a million users look through. An Ad-blocker blocks and makes sure that you don’t get these annoying ads.  

What is an Ad Blocker Software

An ad blocker is a plugin that blocks advertisements from popping up all over the website you are surfing through. With this software, you can go through clear websites with just the content you are looking for. Such websites provide a viewer-friendly experience to the audience.

These browser extensions can also stop the viewers from seeing and clicking on phishing advertisement links, which can turn out to be threats to your PC or download links to harmful files that can corrupt your computer.

Features of an Ad Blocker Software

Ad blockers, today, have a lot of features that come with them. The two main features that are offered by every Ad blocker are Whitelisting and Accepting Non-Intrusive ads.

Whitelisting Whitelisting is the opposite of blacklisting. Whitelisting is the process of picking a few items and providing them with access to pass through the entry veil. In this case, whitelisting refers to the process of filtering select ads to be displayed on the website. The ad blockers permit only the ads which are not links to scam sites or pop-ups that can be harmful threats to your PC. 

Accepting Non – Intrusive ads – Non Intrusive ads are the ads that do not pop up or scroll up on the website window, aggressive when you are trying to navigate through the site. Ad blockers only let non-intrusive advertisements be displayed on the site if the conditions are set. Only ads that are not annoying or intimidating to the readers are permitted to be put up on the ad blockers’ websites.

DNS Blocking – Ads seek the permissions of certain website servers to be displayed. Ad blockers prevent the servers from granting these ads access to be displayed. So, you may or may not see advertisements when you change your DNS. This can put trackers off your scent.

Script Blocking – Ad-blockers go through the script code that is used to design the website and place ads in it. It verifies the data that is passed in and out of the website. The information that comes into the site is compared with a list of ads’ scripts. If detected, they are blocked by the ad blockers. 

Types of Ad Blocker Software

There are two different kinds of ad blocking software. One is the browser extension for browsers, and another type is the standalone products. The browser extensions are add-ons for your web browser.

Adblock Plus, AdGuard, and Ublock Origin are some of the best ad-blocking browser extensions for Chrome, Firefox, Safari, and Opera. Standalone ad blockers are downloadable software for your computer.

AdGuard and AdLock are some of the standalone ad blockers in the market. 

Advantages of an Ad Blocker Software

Just like every coin has two different sides, anything can have its advantages and disadvantages. These are the pro features of ad blockers.

  1. Most of these software are available for both browsers and as stand-alone products.
  2. Ad blockers are available for all Operating Systems, even mobile ones too (Android and iOS)

How does Ad Blocker Software work?

In today’s digital market, there are a lot of ad blockers available. About 90% of them are marketed in the form of a browser extension. The content you see on web pages is rendered (loaded) so that you can see them.

Before rendering, it is in the raw script format. The ad blockers look through this script to detect ads. It has a whitelist to compare with the web scripts to check the website content for advertisements.

If they notice any advertisement script, the ad blocker prohibits it from being loaded. Only when the entire script is gone through by the ad blocker does it permit the website to be loaded. This process is out of the 

Who uses Ad Blocker Software?

Anyone who uses the internet can use ad blocker software. From a toddler who watches rhymes on Youtube to a student who looks for answers to his assignments to a programmer who does complicated code compiling to a retired grandfather who likes scrolling through his Facebook feed, everyone must use an ad blocker.

Especially in the devices used by those who are unaware of the advertisement links that can be fatal to your Operating System. If you own a PC that unaware users use, this is your reminder to install a plugin that blocks ads and pop-ups from the website they look through.

How to choose the right Ad Blocker Software

The perfect ad blocker for you can be determined by a few factors that the user has found favorable. These factors are

  1. Pricing – Most adblocking software is, basically, free. But when you start opting for this software’s premium subscriptions, you will have to pay a small fee for using more features they provide. Some blocking software is worth paying for. You will have to read the details about the services offered by each software on their sites or from the platform/website you downloaded it from. 
  2. Benefits – The adblocker you chose might be free. But the reason it is free could be because of the fact that it offers very few features. You might find another blocker that is not free. This could be because they provide better benefits than the previous one. This could also not be worth your money. Check with the website before you pay. 
  3. Reviews and Ratings – You will be able to read the reviews about a lot of ad blockers. If you have a specific tool in mind, you can scope it out through reviews. Any popular service has ratings and content curated about them. And obviously, there is a reason it is popular. 
  4. System Requirements – Some add-ons might use CPU a bit more than other similar software. Why would a rational computer user spend extra CPU to run a plug-in? If your choice of an ad blocker can reduce the life of your hardware, you picked the wrong one. Find another one that isn’t so hard on your RAM.

It is the responsibility of the user to check with every trustworthy source to back up your information and then proceed in acquiring the software.
