When scheduling your SEO duties, take consideration of each search engine's marketshare; and influence. Google is seen as the number one search engine, but still retains less than 65% of Internet searches. With the new implementation of Microsoft (Bing) technology at Yahoo!, their marketshare influence rises to 29.5 percent. This figure is half of Google's total search percentage, however it still represents (approximately) 30 percent; or one in three search clients.
