Ad blocker

Readers hate ads, publishers need to make money, that why they serve Ads. Due to this Ad Blocker came into picture.

Ad Blocking war:

  • Ad blocking grow, publishers started loosing revenue.
  • Anti Ad blocker used by Publishers. Publishers started using different techniques to recover that revenue like, asking users to white list them, displaying alternative content to Ad Block users and most aggressive was stopping them from accessing their content.
  • Then came ways to block those Anti Ad blocker.
  • Sites like Facebook and Google came up with techniques made Ads look like content then Ads.

This war has gone on for a long time now but there it might end and readers might finally win. Facebook also may have just lost its war on ad blockers.


A new method have been developed by┬áPrinceton and Stanford researchers, which if implemented into the widely available blocker will block Ads and is potentially undefeatable.┬áComputer scientist Arvind Narayanan and his colleagues detailed unveiled a tool that detects ads the same way humans would, by looking at things like container sizes, icon graphics and words like “Sponsored.” It’s called Perceptual Ad Blocker, and is already available as a Chrome extension for you to test out yourself. But in an attempt to avoid getting into the ethics around ad-blocking, the system only covers detected ads with words like “This is an ad,” instead of removing them altogether.

Existing blockers scour a webpage’s source code for signs that they are ads, but those can easily be disguised by anti ad-blocking sites. Narayanan’s team designed Perceptual to ignore hidden HTML markup (or tags) and look instead at the actual content (i.e., words and pictures on the page).

Narayanan and Princeton undergraduate Grant Storey already released a Facebook-specific version of its ad-highlighting extension in November, after the social network announced it would make its ads look like regular posts to thwart blockers. That extension already supports several thousand users, said Narayanan. Today’s release extends that ability to the rest of the Internet, targeting AdChoice displays.

“We don’t claim to have created an undefeatable ad blocker, but we identify an evolving combination of technical and legal factors that will determine the “end game” of the arms race,” Narayanan wrote in a blog post. Out of the 50 known anti-ad-blocking sites his team tested, the perceptual ad blocker was able to highlight ads on all of them without being detected.

Because there are laws around ads being labeled clearly so as not to mislead consumers, there will always be some form of identifier around sponsored content that the perceptual ad blocker is supposed to be able to suss out. This means it has a very good chance of continued success, that is, unless companies find a way to serve you ads without you knowing at all.
