The August migration continues, and October's Google Ads API v26 lets eligible integrators create Local Services Performance Max campaigns and link leads. This adds a concrete API path but does not restore old LSA reports or bidding controls.
Microsoft Advertising is taking Max CPC out of new standalone automated campaigns from October 1. Existing capped campaigns and portfolio strategies retain the control for now, but advertisers creating new campaigns will need to rely more heavily on conversion targets, budgets and portfolio bidding.
Google has moved the Smart Campaign API creation cutoff to September 23. New create operations will fail, while existing campaigns can still be updated and served; Google points developers toward Performance Max, Search or Demand Gen for new automation.
Google Ads has changed a long-standing edge case in automated bidding: budget-constrained campaigns now aim more consistently at their configured target instead of sometimes materially overachieving it.
beehiiv has documented the economics and guardrails behind its rebuilt Recommendation Network, including the 20% fee on paid recommendations, verified-subscriber charging, quality-based auto-pause rules and more granular control over recommendation slots and partner selection.

Paid acquisition is mediated by auction systems, targeting controls, attribution models, creative formats and platform policies. Changes across Google Ads, Meta Ads, TikTok Ads, LinkedIn Ads, Microsoft Ads, Reddit Ads and other material networks can alter who can be reached, what can be measured and how campaigns must be built or automated.
BTN researches concrete product, API, bidding, measurement and policy developments from primary ad-platform sources. Reputable advertising specialists and transparent campaign data can add consequence, but ordinary optimisation advice and isolated return-on-ad-spend claims remain anecdotal. Coverage asks whether a change affects access, cost, targeting, attribution, automation or compliance; which advertisers or builders must adapt; and what evidence separates a platform-wide development from one campaign account or a vendor sales claim.
