What happens when your company’s stock loses more than a billion dollars?

Google is one of the largest tech companies in the world, but it’s facing a crisis that could put the company at risk of losing billions of dollars in revenue and the company’s reputation.

On Friday, Google’s stock dropped about $9, the largest single-day drop in the history of the stock market.

Google is under scrutiny because it’s losing billions in advertising revenue from search advertising.

The company’s revenue from that business, or Search AdSense, has grown at a blistering pace since 2015.

Google’s shares are down more than 50 percent since the start of 2018.

The stock has fallen as much as 30 percent in 2017, and it’s now down about 13 percent since then.

The news isn’t good news for Google, which has been struggling with an ever-growing ad revenue shortfall, according to analyst Ming-Chi Kuo.

Google has had to make decisions to improve the efficiency of its search advertising platform and to pay more attention to its own advertising, which is increasingly reliant on search advertising, he wrote in a research note published on Friday.

“The news of Google’s search ad revenue collapse is a blow to the company, but we expect that Google will not see the same problems with ad revenue that it has faced with search,” Kuo wrote.

Google has been losing money on search, but the company says it’s working hard to fix the problems.

Last month, the company told investors that it was investing in ad-targeting software and creating new ads for its popular Google Maps mobile app.

Google also announced a $1 billion investment to help it build new ad tech to help its search business.

While the stock has taken a hit from Google’s advertising problem, Kuo noted that the company also has been facing a growing amount of negative press.

A number of news outlets are reporting that Google is preparing to release a massive advertising campaign that includes fake news and misleading statements.

In a press release, Google said it is working with local and national media outlets to produce ads that are “false, misleading, and deceptive,” in an attempt to “help us to make a more effective case for Google to be a trusted leader in the digital world.”

According to Kuo, the ads will be based on Google’s “experience and expertise in online advertising and in our search advertising business,” and they will be aimed at people in specific geographic areas.

Earlier this week, Google announced that it will start releasing its first ad campaign targeting people who have “liked” or “re-tweeted” certain posts from other users.

Google will be targeting people based on their Google Plus account.

The campaign, which will start rolling out on Tuesday, will include more than 100 ads targeting people whose posts have been “liking” or sharing posts that “promote a positive view of Google,” according to a Google spokesperson.
