Meta's Personal AI Changes How Customers Buy. Here's What to Do.
Meta's Muse Spark will mediate how customers discover and choose products. Here's what I'm prioritising across client accounts as this shift unfolds and what your business should focus on now.
What is happening
Meta announced Muse Spark, positioned as a step toward personal superintelligence. The idea is an AI that learns your preferences, understands your context, and over time becomes a genuine personal assistant rather than a generic tool. It sits inside Meta’s platforms and mediates how you discover products, ask questions, and make decisions.
Right now this is early. But the direction is clear: the path from ad impression to purchase is going to run through an AI assistant, not just through a feed. That changes a fundamental assumption that performance advertising has been built on.
What I learned from this
Performance marketing runs on intent signals. Someone searches, clicks, visits a page. Those actions tell you where they are in a buying journey. The whole infrastructure of digital advertising - the targeting, the bidding, the attribution - is built around capturing and acting on those signals.
Personal AI changes the architecture. If a Meta AI assistant is the thing that recommends a product to you, the intent signal happens inside the conversation with the AI. It may never show up as a search query or a page visit. The decision is largely made before the purchase click happens.
What this tells me is that top-of-funnel brand presence is going to matter more, not less. The AI will form opinions about brands based on available signals: reviews, content, mentions, reputation. If someone asks the AI which company to use for home renovations and your business has no meaningful digital presence beyond running ads, the AI has nothing to recommend you with.
I have been paying much closer attention to brand signal quality across the accounts I manage. Not just ad performance metrics but the things an AI would use to form an opinion: review volume and sentiment, organic content quality, earned coverage, the clarity of the business’s positioning. That content is increasingly what determines whether an AI-mediated recommendation goes your way or your competitor’s.
What I recommend for your business
You do not need to rebuild your Meta strategy because of this announcement. What you should do is stop treating brand and performance as separate problems with separate budgets and separate goals.
The performance budget gets your ads in front of the right people right now. The brand investment determines whether those people - and the AI systems mediating their decisions - have a positive impression of you when they are ready to act.
Three specific things to focus on: get your Google and Meta review count up by actively asking satisfied customers for reviews. Publish content that explains what you do, who you serve, and what makes you different - not to rank in search but to exist as a signal. And make sure your business profiles are complete, accurate, and consistent everywhere they appear online.
The AI will make the brand-versus-performance wall hit sooner and harder than it would have without it. The businesses that will benefit are the ones who are genuinely known and trusted before the AI starts making recommendations at scale. Start building that now.
