Google paid more than $600 million in ad price last year, according to an analysis of data from the ad network.
Google also spent about $824 million on its Google AdWords advertising platform.
That was the largest sum in any one year in the company’s history.
But that’s only part of the story.
Advertisers are also paying Google an average of $3.03 for every $1 they spend on ads on the site, according a report by the research firm Avalere.
It’s also worth noting that Avalere is a firm that tracks Google ads, not just its own.
In fact, Avalere said it did not make any payments to Google last year.
That’s because Google has been spending more on ads since its 2014 acquisition of Google+.
Google has paid an average $4.42 per click on its ads since 2013.
It was about $2.38 last year and $2 in 2016, Avalheim said.
Adtech companies that sell ad tech have also been spending money on Google.
In 2016, for example, Facebook and Twitter paid an annual average of about $5,000 to Google for their ad tech, Avaliere said.
Those companies also had a net profit of about 1 billion yuan ($11.4 million) last year from the purchase.
But Avalere also found that the company spent about 8 billion yuan on ads last year — $1.1 billion less than it had in 2016.
That is because Facebook and Instagram also dropped their budgets for the ads market.
Instagram had more than 3 billion yuan in ad spend in 2016; Facebook only about 1.3 billion yuan.
Google, meanwhile, has spent an average per click of about 6.5 times as much on its own ads in 2017, Avalère said.
The company also spent a lot on other products and services it does not sell, such as its Google Shopping cart.
The ad spend by those companies was about 11 billion yuan, Avalier said.
It also spent $1 billion on Google Plus in 2017 and another $400 million on AdSense, Avalieri said.
But its overall advertising spend fell by about 20 percent.
Ad revenue for Google is expected to grow by about 30 percent this year, Avaliser said.
Google is also paying the lion’s share of its advertising costs to its YouTube and Google+ services.
Those two have a combined $1 trillion in ad revenue.
Avaliere estimates that YouTube ads accounted for about 40 percent of Google’s ad revenue in 2017.
YouTube ads have also risen significantly in value since the acquisition of YouTube, from $3 billion in 2014 to $15.4 billion in 2017 as YouTube grew its audience and its advertising business.
Google’s other revenue streams, such to content owners, have also seen a jump, Avalire said.
Its digital advertising business, which includes YouTube ads, generated $6.3 trillion in revenue last year for Google.
That makes Google the biggest single advertiser in content and media.
But Google also is spending a lot of money on its content management systems.
That includes YouTube’s advertising business that it has spun off.
It spent $4 billion on its ad buying business last year; its digital ads business generated $4,979 million in revenue.
YouTube has also been adding ad blockers, or paid-for-privacy programs, to its site and apps.
Avalier estimated that YouTube spent $2 billion on ad blockers last year alone.
Google did not provide a breakdown of its paid-content spending last year but Avaliere says that includes more than 4,000 ad units.
In the last few years, Google has also spent more on ad inventory, including inventory from its ad tech companies, Avalir said.
Avaliers analysis of Google advertising spending showed that it spent $664 million in 2016 on inventory from Google’s advertising technology companies, but that figure includes other assets.
It doesn’t include the $1,250 million spent by YouTube on advertising on its site, Avaliers said.
A spokesman for Google said that it does “not discuss its business strategy.”
Avalier’s report comes as Google’s stock has surged over the past few weeks, and its stock price has risen by about $1 since last December.
Google has had to pay a lot more than usual in the past year to buy up its stock.
It paid $5.1 million in cash to buy back $20 billion worth of stock in 2016 and another buyback of $15 billion in March 2017.
That purchase included $50 billion of stock from Google Ventures, the company that invested in Google, Avalera said.
That stock price surged to nearly $120 per share in March 2018.
