TheNewsGuru gathered that Google is facing a wave of angry customers after advertisements from major brands and the United Kingdom government appeared alongside content from hate preachers and extremist groups.
Brittin said Google had made a commitment to doing better and would simplify advertiser controls, add safer defaults and increase investment to enforce its ad policies faster.
And late last week, the United Kingdom arm of advertising agency giant Havas said it was halting advertising on Google and YouTube "until further notice".
Google, which owns YouTube, responded by saying it would take steps to better monitor content on the site and give advertisers more control over where their ads appear. Changes to the company's advertising policies were announced after they appeared alongside offensive content, such as videos promoting terrorism or anti-Semitism.
The main issue appears to be with automatic advertising, as Google's DoubleClick Ad Exchange initiative relies on programmatic buying to match mainstream brands with content. Google now accounts for 85 per cent of all digital ad spend in the United Kingdom, and while it removed almost two billion offensive ads and blacklisted 100,000 publishers past year, it is still falling short in providing a completely brand-safe environment.
"Google is responsible for ensuring the high standards applied to government advertising are adhered to and that adverts do not appear alongside inappropriate content", the United Kingdom government said in an emailed statement.
"We are horrified that our campaign - which is the total antithesis of this extreme, negative content - could be seen in connection with them", the company said in a statement.
Google's advertising policy is created to address publishers not the content itself, hence why so many extremist web sites, which are quite open and public about who they are (and therefore not misrepresenting themselves as publishers), are profiting from fake news. We take our responsibilities to these industry issues very seriously.
Mark & Spencer's withdrawal is another serious blow for Google, which has a near monopoly on the digital advertising market, at a time when the company is facing a crisis of confidence amongst advertisers. "We have a review underway on how to improve, which has been going on for some time, and we're accelerating that review".
The European boss of Google has issued a grovelling apology after paid-for adverts appeared next to extremist content on Google's YouTube platform - Sky News reports.
A spokeswoman for L'Oréal said the company was "unaware" and "horrified" that its ads were being placed on such YouTube channels. With millions of sites in our network and 400 hours of video uploaded to YouTube every minute, we recognise that we don't always get it right. But advertisers weren't using such tools, .
