Mobile search growing faster than ad spending

Some good and bad news on the mobile search front: Mobile search traffic is growing substantially, but so far mobile ad spending is remaining a small slice of the overall search ad market, according to a new report by RBC Capital Markets.

The study by RBC Capital Markets says mobile searches represent 8% to 10% of overall search queries in 2010 but less than 2% of paid search spend, MediaPost reports. RBC Capital says mobile searches will quadruple in the next three years, but the mobile ad market will remain rather small for Google, only reaching $2-$3 billion in the next few years.

One promising sign is that mobile search ads drive three to five times higher click-through rates. Still, because of the smaller screen real estate, the average mobile search shows only 1.1 paid search result, compared to 9.2 search ads per query on a desktop screen. That indicates mobile search might never fully close the gap between mobile’s share of overall search queries and its share of search advertising.

TechCrunch believes the report is a bit optimistic on the ad revenue front, and has more detailed analysis of the report.
