adCenter feature review: Get negative! It could have a positive impact on your campaigns.
As part of the adCenter upgrade on Saturday, we added the ability to work with negative keywords at the campaign level so they apply to all the ad groups in the campaign. Previously, this was only possible at the ad group level.
Context & Ripple Effects
Microsoft's adCenter update lands weeks after Yahoo opened its Panama advertising platform, making mid-2007 a season of rapid platform overhauls among the paid-search rivals. The change itself is small — negative keywords move up a hierarchy level — but it targets a real workflow cost: until Saturday's upgrade, advertisers had to duplicate their exclusion lists in every ad group.
First-order effects
- adCenter advertisers can now set exclusions once per campaign instead of repeating them across each ad group, directly cutting spend on irrelevant queries and trimming campaign setup time.
Second-order effects
- The release keeps Microsoft matching the control granularity advertisers already manage across Google AdWords and Yahoo's freshly launched Panama, removing one more friction point for buyers running campaigns on multiple platforms.
Third-order effects
- If the platforms keep closing feature gaps at this cadence, keyword-level controls become table stakes in paid search and differentiation shifts toward tooling and workflow efficiency rather than basic match mechanics.
The trend: Paid-search platforms in 2007 are converging on advertiser controls through steady release cycles, with Microsoft using adCenter upgrades to close the gap on Yahoo's Panama and Google AdWords.
