According to the Q2 US Search Engine Performance Report, Google continues to dominate the paid search engine marketing industry. During the second quarter, Google was responsible for 77.4% of all US search marketing dollars spent. Yahoo was a very distant second with 17.8% of the market and MSN captured 4.8%. Despite their much smaller market shares, Yahoo and MSN still prove to be great advertising investments for many Internet marketers. The best strategy is to incorporate all three of the major search engines into your PPC marketing campaigns.
