As advertisers continue to scale their investments across Meta’s ecosystem, ensuring transparency and control on rapidly growing platforms like Threads is critical. With Threads surpassing 400 million monthly active users (MAUs) globally in 2025, the platform presents a massive opportunity for brands to reach engaged audiences—alongside a growing need for trusted, independent optimization.
Today, we are proud to announce the expansion of our AI-driven Meta Content Block List optimization solution to Threads feed. This expansion of our Social Optimization solution provides advertisers with even greater brand protection and the ability to maximize their return on investment (ROI) across the world’s largest social platforms.
Driving Meta Performance Through Brand Suitability
In a digital-first world, efficiency is everything. The impact of IAS Social Optimization is already being felt by global brands.
By dramatically reducing wasted ad spend on unsuitable media, the retailer was able to reinvest those savings back into working media, increasing the volume of brand-suitable placements and overall campaign effectiveness.
“Our AI-driven, content-level analysis empowers advertisers to drive performance and confidently scale their investments on social platforms with trusted, third-party, independent solutions. We continue to innovate and deepen our relationships with global partners like Meta to provide end-to-end campaign support for advertisers, ensuring they can avoid unsuitable content and maximize their campaign effectiveness.”
