Media buyers and planners reported that online ad spending continued its robust growth in the first quarter, and said they anticipate second-quarter online ad buys will surpass those of the first quarter, according to a new report by Deutsche Bank and MediaPost, based on their joint survey of 108 media executives.

Some 71 percent of the execs said their clients' spending increased from the last quarter of 2004; 16 percent reported flat budgets. Seventy-one percent also said they expect second-quarter spending to also rise, and 51 percent expect clients to spend at least 11 percent more in the second quarter.

Most executives surveyed predicted an increase in both premium display ad prices and run-of-network prices. Respondents similarly predicted a second-quarter increase in cost-per-click fees.
