               VALUECLICK (NASDAQ: VCLK) REPORTS ESTIMATED THIRD
                                QUARTER REVENUE

September 22, 2000 - - Westlake Village, CA - - ValueClick, Inc. (Nasdaq: VCLK),
the leading pay-for-performance online advertising network, today announced its
revenue estimate for the third quarter ending September 30, 2000. In addition,
ValueClick's Board of Directors has approved a $10 million stock repurchase
plan.

Based on the results of the quarter to date, the Company estimates revenue for
the third quarter of 2000 will be between $9.5-10 million, with a strong outlook
for the fourth quarter of 2000. In a quarter of soft advertising spending
overall, the Company has upheld consistently high margins by maintaining pricing
structure and effectively managing costs. At the same time, ValueClick was able
to aggressively expand globally and introduce a number of technological
advances, including DoubleClick's DART( technology that enhances advertisers'
targeting capabilities.

"We experienced a dip in Internet advertising expenditures, which has been
consistent with market performance of our competitors over the past two
quarters. As a result, we took steps to improve margins and implement new
technologies that will enhance our offerings to advertisers and publishers,"
said James Zarley, Chairman and CEO. "As many industry analyst firms project
continued growth in the online advertising sector, we believe the Company is
uniquely positioned to help those advertisers reach users through ValueClick's
performance-based network of more than 14,000 sites."
