One of the most popular ad blockers is releasing a mobile browser, which could be huge — but costly for companies like Google

Adblock Plus, which claims to be the most popular ad blocking tool, is launching its first mobile browser.

The Android browser will automatically block ads, which Adblock Plus says will save up to 23% of a user's smartphone battery life, and also save on their data plan. The app is initially launching in beta, so users can provide feedback on the experience.

Further down the line Adblock Plus also plans to add additional tools within the browser such as malware protection.

As with the Adblock Plus desktop browser extension, which the company says has been downloaded more than 400 million times and is said to have 50 million active users, some ads do get through the net, or are white-listed, in other words.

Almost all ads — including "native ads" like Facebook ads that appear in the newsfeed or ads that appear on publishers' websites that have the same look and feel as other content on the site — are blocked as standard. Publishers and advertising networks - such as Google's huge display network, or other independent ad servers — then have to apply to get each type of ad they serve on to Adblock Plus' "acceptable ads" list.

Adblock Plus then works with the ad seller to help their ad match its acceptable ads criteria and the whitelisting proposal is submitted to its user forum, in order for the community to declare any concerns. The type of "annoying" ads that don't make the cut are usually pop-ups, pop-unders, "interstitials" that interrupt the reading flow on a page, and ads that are not clearly labeled as ads (but plenty of other ads like standard top of the page banners get blocked too.)

If the publisher or an ad seller is small — a WordPress blog with two ads, for example — Adblock Plus and its parent company, the Germany-based Eyeo, won't charge for companies to go through this process. But bigger entities like Google, Microsoft, Amazon pay huge fees to Eyeo to get their ads unblocked: 30% of the additional revenue they would earned were the ads unblocked, according to a Financial Times report.

Ben Williams, Adblock Plus operations and communications manager told Business Insider that only about 10% of companies on its whitelist pay for their ads to be unblocked. He said the fees are based on the scale of the company and how much time Eyeo's 38-strong team will need to take to get their ads into shape.

And even then, users can always choose within the desktop browser extension, or the new Android app, simply to suppress all ads — even acceptable ones. Only a "low single digit" percentage of users actually do this, Adblock Plus claims.

A way to get around Google blocking Adblock Plus from the Android Play Store

So if Eyeo is demanding huge fees from Google already, and its users can choose to blanket block all its ads, surely Google could just block the Android app from the Google Play Store? (At the time of writing, the app is not yet live on Google Play, either, as it waits to go through the approval process.)

Williams said it has happened before. Back in 2013, Google removed Adblock Plus and other ad blockers from the Play Store. At the time Google said this was because the app violated a Section 4.4 of its Developer Distribution Agreement, which stipulated that apps cannot interfere with another app's functionality.

A browser, however, will not affect other apps. But it's unlikely Google will look kindly on it. Indeed, Williams hinted that this was part of the reason Adblock Plus didn't decide to go down the iOS route first, like most app developers.

"iOS is harder to develop on, it's a walled garden that's more difficult to get an API, simply put ... I think that might have been part of the reason, and also, most of the people in our office use Android ... and in Europe ... Android is an open development system," Williams added.

Adblock Plus is already available on Android, but users have to first download the Firefox browser, and then side-load the Adblock Plus afterwards - which Williams said "is a bit of an issue for a normal user, and more than they can bear" - hence the need for a browser.

Williams said the mobile browser is the company's first concentrated effort into mobile adblocking, so it may take time before it becomes ubiquitous: "We're just starting on Android for now. I want to make clear that this is our first foray into the mobile solution and we are taking a scalpel to rather than a hammer - doing one thing and doing it right ... I really hope we get a lot of people but I wouldn't expect it to rival our desktop [userbase] yet."

The argument against ad blocking

Earlier this month another mobile ad blocking solution made the headlines: Shine, an Israeli ad blocking software company that claims to have the support of mobile carriers, which could start rolling out ad blockers among their customers to reduce infrastructure costs from data-sucking ads.
