Northbeam Adds Incrementality Testing to Attribution Suite

Executive Signal Summary

Northbeam announced a new incrementality testing feature to complement multitouch attribution (MTA) and marketing mix modeling (MMM), aiming to complete a three-part attribution approach. VP of Product Stas Goldobin said incrementality acts as a calibration layer between MTA and MMM and that Northbeam worked actively in early 2026 to "complete the trifecta of digital attribution." The product currently supports testbeds on Meta and Google (which Northbeam treats as six properties: Google Search, Google Shopping, Performance Max, Demand Gen, YouTube and Google Ads). Northbeam plans to expand platform coverage and intends to cover roughly 80% of an average client's budget with incrementality tests within a few months. Goldobin noted platform AI retraining cycles complicate tactical experimentation.

Adds an incrementality capability that bridges MTA and MMM, supports major platforms (Meta and multiple Google properties), and could change how omnichannel advertisers calibrate measurement and budget decisions.

Threads tests Gems to honor valuable posts daily

Threads is testing a new feature called Gems, which awards up to 25 outstanding conversations daily with a visible diamond badge. The selection is algorithm-based, focusing on originality, timeliness, and authentic discussion, regardless of follower count. Posts or direct replies qualify, but reposts and content cross-posted from Instagram are excluded. The feature is currently limited to public US-based accounts of users aged 18 and older, though the badges are visible globally, including in Germany. Recipients get a notification and can share the badge. Users can hide the label if desired. Initial hints appeared in August via app researcher Alessandro Paluzzi. Threads aims to encourage original and engaging content, with no negative impact on reach for non-recipients.

Meta Bans TikTok Ads on Its Platforms in Multiple Regions

Meta has banned advertising for TikTok on its platforms (Instagram, Facebook, WhatsApp) in several countries, including the USA, Japan, Vietnam, Canada, Egypt, Indonesia, and Thailand. This action, confirmed by Meta spokesperson Chris Sgro, prevents both ByteDance and third-party advertisers from promoting TikTok within Meta's ecosystem. The ban is seen as a competitive move amidst escalating rivalry between Meta, ByteDance, and YouTube. It may also be linked to Meta's recent $16.7 billion settlement with US states over youth safety, which includes conditions that require competitors like TikTok and YouTube to implement similar protective measures, suggesting a strategic pressure tactic to ensure they share the cost and responsibility of child safety initiatives.
