Chrome Extensions Move to Manifest V3 Starting June

Starting June 3, 2024, Google began deactivating Chrome extensions based on Manifest V2 in Beta, Dev, and Canary channels as it migrates to Manifest V3. The migration shifts background context to Service Workers to save resources and blocks remote-hosted code for security. Google reports that about 85% of active extensions have already migrated to Manifest V3, with a broader switch to follow in early 2025 alongside changes to third-party cookies. The move prompts concerns from ad-blocking developers over limitations in the Declarative NetRequest API, including a 30,000-rule cap versus the tens or hundreds of thousands of rules needed by typical blockers. Google has paused Manifest V2 support and provided migration guidance. The article notes potential impacts on adtech and user privacy, while highlighting Google's stance on security and control over extensions.

Balancing Stakeholder Needs: Key to Ad Tech Success

An AdExchanger opinion piece argues that effective product marketing in ad tech must balance the needs of multiple stakeholders—publishers, advertisers, and users—whose interests can conflict. It emphasizes identifying interdependencies and potential conflicts across product teams, and outlines five foundational tips: identify conflicts, remove silos between internal teams, build a companywide product community, empower product managers, and pursue a holistic, outcome‑oriented approach with transparent metrics. The article uses a concrete example of header bidding integrations that can inflate publisher revenue and bid density but also raise browser latency and potentially reduce readership. It also underscores a unified user strategy that weighs end-user interests alongside privacy and regulatory considerations, suggesting that happy users ultimately benefit all stakeholders and long‑term monetization. The piece appears as part of Data‑Driven Thinking and references Gertrud Kolb as a contributor.

Positive Social Impact in Advertising: Q&A with Sigma Software - ExchangeWire.com

ExchangeWire presents a Q&A with Sigma Software Group leaders Olha Paramonova (Vice President, AdTech) and Katherine Tuluzova (Executive Vice President, North America) on how to maintain a positive social impact in advertising. The discussion covers the current risks of modern programmatic advertising—privacy violations, malware, data misuse, and invalid traffic—and argues that standardisation and consolidation are essential to protect users and the ecosystem. The piece highlights notable industry moves, including Human’s merger with PerimeterX and its acquisition of clean.io, and Eyeo’s purchase of Blockthrough, as steps toward safer ad tech and helping publishers recover ad-blocked revenue. It also emphasizes the value of first‑party data as a privacy‑preserving alternative to third‑party cookies, the benefits of direct publisher–advertiser partnerships, and the challenges of enforcing standards across nascent channels such as DOOH and the metaverse. ATS Singapore 2023 is scheduled for October 3–4, 2023.
