Google Has Over 75% Of US Search Ad Market

New figures out on search advertising spend from Efficient Frontier show Google continues to dominate the market, stats that will no doubt complicate the company’s goal to gain approval of its deal with Yahoo on search ads. However, it is interesting how in Japan, it’s a much more 50/50 market split with Yahoo, showing that Google does have weaknesses.

For the second quarter of 2008, Google had 77.4% of the search advertising spend according to data tracked by Efficient Frontier, which manages ad campaigns for a wide variety of large advertisers. The data covers 23 billion ad impressions and 390 million clicks. Google’s share includes a small percentage of contextual ad spend (which is not search), as does Yahoo’s. You can see these broken out in the share chart below for Q2 2008:

Search Ad Spend: Q2 2008

Over the past year, Google has continued to gain share of ad spend pulling away primarily from Yahoo (Note: I don’t have figures for Q3 2007 at the moment, so I’ll update later when they come in):

Paid Search Share Over Time

That drop is bad for Yahoo, since its Panama ad system, launched last year, was supposed to help increase the amount advertisers were spending with the company. Of course, the company has also had declining search share overall, so fewer impressions can also mean potentially less spending with Yahoo.

Keep in mind that Yahoo could have a declining share of the search spending pie yet still earning more money as long as the overall spend on search advertising is growing. And it is, says Efficient Frontier — but not to Yahoo or Microsoft’s benefit.

Instead, Google is getting more of the new money coming in than the others. Officially, Efficient says Google gets $1.10 of every new dollar spent on search. That’s complicated to understand, even after I talked with them about it. So stick with the bigger point — the others are seeing both declining share of overall search spend and a declining amount of actual earnings.

This is great for Google with the exception that the company is currently trying to win US government support for a plan to have Yahoo carry some of its search ads. The latest numbers hold no particular surprise about how dominant Google is, but they’re fresh evidence that you’ll no doubt hear Microsoft parroting in terms of why a Google-Yahoo deal would be bad for competition.

Another stat that might get trotted out is the cost-per-click figure. Google’s cost per click is well above the others, about $0.70 on average, with Microsoft around $0.60 and Yahoo around $0.50. Google’s CPC rate has actually dropped the past two quarters (as has Yahoo’s), but no doubt it will be argued (as it already has been) that a Google-Yahoo deal will just allow Google to "set" the market and make CPC rates go higher (officially, Google says the market sets prices). Here’s the chart (note that spend by financial services advertisers is not included in it):

Average CPC, Q2 2008

Good news from Microsoft — for two quarters in a row, it has claimed the title of best ROI. The problem, of course, is that while advertisers might get better ROI, there’s a lot less search traffic for them at Microsoft to get it from:

Search ROI, Q2 2008

Back to the competition aspect: just because Google’s dominant in the US doesn’t mean it plays that way out in all countries. In particular, Google is behind in China, South Korea, Russia and Japan. Efficient has spend figures for the latter, which show Google has just barely 50% of the Japanese market. The other half belongs to Yahoo:

Note that in Europe (excluding the UK), Google has over a 90 percent share. Fortunately for Google, the Yahoo ad deal is US-only, so it won’t have to face European regulators who likely would take a hard look.

Finally, many who worry that search spend will decline because of current economic woes should feel reassured that, on the whole, Efficient says spend is increasing. But some sectors are feeling the impact:

Search Spend By Vertical, Q2 2008

Overall:

  • Auto spend rose despite the hike in gas prices.
     
  • Financial spend after several drops is about the same as a year ago. Efficient said that a drop in mortgage-related spending is being made up for by spend by advertisers with credit products.
     
  • Retail spend is about the same as a year ago. The Q4 2007 spike is likely due to the holiday shopping season.
     
  • Travel is lower, even when looking back on a season basis to the same quarter last year.
