The US company continues to combat what it describes as "bad ads" and has unveiled figures for the past year. More than six million ads were withdrawn per day.
Google considers "bad ads" to be all those who violate company policies. This group includes advertisements disguised as news, malware or phishing scams.
In 2018, Google introduced 31 new ad-related policies. As a result, the American technology released the figures for 2018 having concluded that, daily, were more than six billion the ads removed.
The 2.3 billion ad withdrawn represent a reversal of the trend that was taking place. By 2016 1.7 billion had been removed, rising to 3.2 billion in 2017. In 2018 there was therefore a decrease of 28% compared to 2017.
A publication by Scott Spencer, director of Google, revealed some more details. The number of phishing ads removed was approximately 58.8 million while, due to the improvement in machine learning technology, almost one million "bad advertisers" accounts were closed.
The report also highlights the withdrawal of 207,000 ticket reseller ads and 143,000 election-related ads in the United States, also referring to the total removal of ads from approximately 1.5 million applications.
