When extending a search campaign to the Microsoft Audience Network, what is the maximum audience ads negative bid adjustment?

When extending a search campaign to the Microsoft Audience Network, the maximum audience ads negative bid adjustment is -100%. This allows you to completely opt out of showing ads on the Audience Network for that specific campaign, effectively preventing any spend there. A -90% adjustment would still allow some ad impressions and spend, albeit at a reduced bid. -10% and -50% are also partial reductions, not a complete exclusion. The -100% option provides full control to stop Audience Network participation if it doesn't align with your campaign goals.
