Google’s internet marketing ranking continues to decline.

The company’s internet advertising business, which includes the search and ad-selling services it sells, was ranked 19th on Google’s global rankings in 2018.

But Google says it has made progress in recent years to get to that number, and that the average online ad revenue for its competitors is about $30.50 per person per month, up from $22.50 a year ago.

It’s the fourth consecutive year the search engine has reported a decline in the rankings, and Google says its overall internet advertising revenue fell from $8.3 billion in 2016 to $7.7 billion in 2017.

That’s because Google’s ad business has grown so quickly.

It now accounts for about a third of all internet traffic, according to Google.

The search giant said it expects ad revenues to continue to grow at an average rate of 3 percent per year through 2020.

But the decline in internet ranking is also due to a slew of new ad-tech companies competing for the same online ad market.

Some of those companies, including DoubleClick, Doubleclick Ad Network, AdRoll, and AdWords, have also seen their rankings drop.

Google said it had lost about a million ad clicks over the past year as new competitors joined the marketplace.
