                                 Solutions -

NEW YORK, Aug. 19 /PRNewswire-FirstCall/ -- DoubleClick Inc. (Nasdaq: DCLK), the leading provider of marketing tools for advertisers, direct marketers and Web publishers, today announced reseller partnerships with leaders in the search engine marketing space: iProspect, The Original(R) Search Engine Marketing Firm, and TrafficLeader, a full-service search marketing company. DoubleClick will leverage iProspect's natural search engine marketing services and TrafficLeader's paid search inclusion technology on behalf of its clients who are looking to augment their search engine marketing and increase ROI on the Web. The agreements expand DoubleClick's search engine marketing solutions for its clients -- its customers are already able to use the DART For Advertisers and DART for Publishers interfaces to traffic and track their paid listings through Click Commands and Tracking Ads.

Paid listings (or paid placement), which ensure that a website or Web pages appear in a specified position in the sponsored search results set, represent just one available search engine marketing tool. "Natural" search engine optimization and paid inclusion round out the options for marketers, for whom increasing visibility on search engines is critical to drive traffic and conversion. Recent DoubleClick research shows that search engines have the greatest impact on users researching a purchase (41% report using search engines most often to find a website).(1) As a result of the reseller agreements, natural search engine optimization and paid inclusion will now be made available to DoubleClick clients through its direct sales team.

"DoubleClick's relationships with iProspect and TrafficLeader enhance our search marketing offering for clients who recognize its importance for reaching and converting prospects," said Doug Knopper, VP and GM, Online Advertising Solutions, DoubleClick. "This comprehensive offering is only the first of many powerful search engine marketing solutions that we, together with leading companies in the search market, plan on offering to customers looking to increase their return on investment on the Web."

iProspect has a wealth of experience helping Fortune-sized clients increase their website's visibility through natural search engine optimization. iProspect optimizes a site's actual content and architecture to be "search engine friendly" through proven methodologies. As part of the agreement, iProspect's services will leverage the data provided by DoubleClick's DART technology.

"Our DoubleClick partnership will drive dramatic increases in search referral traffic to their clients from search engines like Google, Yahoo, AltaVista, MSN and others," said Sage Peterson, Vice President, Strategic Alliances, iProspect. "Nothing is more powerful than being found at or near the top of the 'actual' search results when interested prospects search for you using keywords and phrases relevant to your website -- and nothing is more damaging than having these same prospects find your competition if your site is not properly optimized. This partnership will assure that DoubleClick's customers are on the correct side of that value equation."

TrafficLeader is a full-service search marketing company specializing in paid inclusion, which guarantees that a website or Web pages, that the search engines' technology might have missed, will appear in the search engines' results lists. TrafficLeader guarantees inclusion into the world's most important search indexes, actively manages paid placement campaigns, provides site optimization techniques, and reports in-depth ROI metrics. TrafficLeader's reporting product can be integrated with DoubleClick's DART for Advertisers.
