Which inventory type provides the strictest preventative brand safety measures in partnership with Integral Ad Science (IAS)?

The Limited inventory type offers the strictest preventative brand safety measures because it restricts ad placements to only the most brand-safe content, as verified by Integral Ad Science (IAS). This option minimizes risk by avoiding content that could be deemed sensitive or inappropriate. Standard inventory balances reach and safety, offering broader placement while still employing brand safety measures. Expanded inventory prioritizes reach, allowing ads to appear across a wider range of content, including some that might be considered less brand-safe, to maximize impressions. Therefore, for the highest level of brand safety in partnership with IAS, Limited is the correct choice.
