Question: I'm looking for a solution that offers performance and transparency for retargeting and branding campaigns - do you know of any options?

For a solution that balances performance and transparency in retargeting and branding campaigns, you may want to take a look at AdRoll. AdRoll uses AI and machine learning to optimize marketing campaigns across multiple channels, including display, video, native, retargeting, and brand awareness ads. Features include dynamic creative optimization, marketing automation and detailed analytics that should help you increase brand awareness and drive site visitors and conversions more effectively.

Another good option is RTB House, which uses Deep Learning technology to build targeted ads that drive sales and loyalty. It offers self-optimizing campaigns, personalized retargeting, and a 3-layer brand safety protection. The company also works with clients to build new ad formats and technologies based on their needs, so it's a good fit for agencies and e-commerce companies looking to improve their online marketing.

Implicit is also worth a look. The company targets ads with artificial intelligence and a panel of representative internet users, providing transparent purchases and detailed reporting. It reaches more than 30,000 websites and generates billions of impressions each day, so it's a good option for advertisers who want to avoid cookies and who want to target based on socio-demographic, behavioral or interest criteria.

Finally, Jivox offers a cloud-based platform for real-time, personalized and dynamic ads across multiple channels. It offers creative automation, data-driven decision-making and AI-powered recommendations, which can help brands dramatically improve their return on investment through performance auto-optimization and real-time analytics. That makes Jivox a good option for brands that want to scale their marketing while maintaining high levels of personalization.
