Search Ads + Your Phone = Google
If you’re looking at at a search ad on your phone, there’s a chance, statistically speaking, that it’s from someone other than Google.
But it’s a very, very small chance. Not much more than three percent, per this chart from Macquarie Group, using data from Efficient Frontier:
And this chart understates Google’s dominance in mobile search ads, because it only tracks advertisers who are spending on both Google and the Yahoo/Microsoft JV. Yahoo/Bing’s true market share, according to Efficient Frontier, is closer to one percent.
Greg Sterling at Search Engine Land does some back-of-the-envelope math and concludes that will give Google about $1.1 billion in mobile search revenue by the end of the year. Which syncs up directionally, at least with Google’s boast that it was on a $1 billion run rate for all mobile ad revenue last fall.
