Google

Audience size lowered from 1000 to 100 users

Google has reduced the minimum audience size to 100 users across all campaign types, including Search, Display, and YouTube. The change applies to Customer Lists, remarketing, and other audience segments, making audience targeting easier for smaller advertisers. Google also lowered the threshold for appearing in Audience Insights from 1,000 to 100 users, according to updated help documentation.

AI Suggestions below performance graphs

Google Ads is testing a new placement for Ads Advisor suggestions directly under the main performance graph. These AI prompts appear where advertisers review results and include tips like comparing conversion rates or finding ways to improve performance. The update points to a more assisted Google Ads experience, with AI offering guidance in real time during analysis.

Google adds Google Maps to Demand Gen channel control

Google Ads is rolling out Google Maps as a selectable channel within Demand Gen’s Channel Control settings. Advertisers can now include Maps alongside other channels or create standalone campaigns focused on local intent. The update gives marketers more control over placement and helps better align Demand Gen campaigns with location-based user behavior.

Ads in AI Overviews expand to all available markets

Google has updated its rollout of ads in AI Overviews. These ad placements are now available in all countries where AI Overviews are live, not just a limited list of markets. Eligible formats still include Text and Shopping ads from Search, Shopping, and Performance Max campaigns, which can appear within or around the AI-generated overview based on relevance.

Google Merchant Center adds new features to Product Studio

Google has expanded Product Studio inside the Merchant Center with three new features. Advertisers can now animate product images into short videos, remove backgrounds directly in the platform, and increase image resolution for better quality. These additions go beyond the original image generation tool and aim to help merchants create cleaner, more engaging visuals for Shopping and ads.

Microsoft Ads

Bing Ads tests underlined text in Search Ad descriptions

Microsoft is testing underlined words in Bing Ads search descriptions to highlight key phrases. The underlined text is not a separate link, the entire ad remains clickable. This appears to be a visual test aimed at improving scanability or click-through rate, without changing ad functionality.

Microsoft expands Performance Max with new reporting and control features

Microsoft Advertising has rolled out several updates to Performance Max campaigns, adding deeper reporting and more control. Advertisers now get asset group–level URL tracking, segment reporting by audience, device, and time, plus support for up to 10,000 negative keywords per campaign. Microsoft is also testing new customer acquisition goals, allowing bids to prioritize or focus only on new customers for purchase campaigns.
