Meta Expands AI Ad Tools and Adds Creative-Level Data

At Advertising Week on October 6, Meta made video generation from static assets in Advantage+ creative generally available, began rolling out Ads Creative Studio to more advertisers, and opened Customer Life Cycle Strategy, which recommends excluding existing customers from acquisition campaigns, to all advertisers. Its AI business assistant gains memory, while agentic actions such as changing budgets are only beginning to be tested. Meta claims 5% more conversions for advertisers who follow the assistant’s advice but has not explained the method.

On October 27, Ads Manager also gained a Breakdown view showing how individual images, videos and text variations perform, excluding collection and carousel formats. This builds on the Muse launch in our September digest.

What this means for businesses: Advertisers can make more video from existing images and see which creative elements work, but should check which tools are live in their accounts.

Why it matters: As targeting becomes more automated, creative is the lever advertisers still control.

Social Content Is Increasingly Visible in AI Search Results

A SE Ranking study of 100,000 keywords found social platform links in 67.66% of Google AI Overview responses, 32.39% of Google AI Mode replies, and 8.4% of ChatGPT answers. According to the study, YouTube is the most cited source in AI Overviews. Reddit and LinkedIn lead among social platforms in ChatGPT, though each appears in under 1% of its answers. Citation patterns also shift quickly: SE Ranking’s data showed Reddit’s share of ChatGPT citations falling 86.4% in four days in August. AI visibility therefore calls for a platform-by-platform approach.

The study shows that social content appears in AI answers. It does not show that posting more often improves visibility.

What this means for businesses: Posts, videos, and profiles can become sources that AI tools cite.

Why it matters: AI search is becoming a discovery channel, and the platforms it favors differ by tool.

What businesses should do: Check which profiles and videos AI tools surface for your brand, and keep YouTube, LinkedIn, and Facebook pages accurate and maintained. Ongoing social media management can help keep that presence consistent.
