Technological innovation remains a main differentiator for paid click advertising revenue at Google, according to Merrill Lynch's Justin Post. The research analyst told clients Friday morning that paid click sales growth of 52 percent year-over-year and 13 percent growth for the quarter sequentially "suggest healthy search traffic and continued sponsored ad relevancy improvements.

He remained positive on Google's ability to gain traffic share, noting that aggressive research and development along with capital expenditures were proving to be competitive differentiators.

The company was already leading rivals with 3.5 billion search queries performed in March alone. Yahoo was second, with 2.0 billion, and Microsoft Sites took third place with 798 million, according to comScore Networks.

We believe Google will continue to take share in an attractive market, and the company's technology strengths will lead to new opportunities in traditional media, payment processing and on-demand software.
