⚡ Welcome back.

This week, the visibility game changed on 3 fronts at once. Meta is about to pass Google in global ad revenue for the first time. LinkedIn just became the 2nd most-cited source in AI search. And across platforms, the rules for who gets seen, who gets cited, and who gets the ad dollar are being rewritten in real time.

Today, we're talking about:

Meta is on track to overtake Google in global ad revenue
LinkedIn ranks #2 in AI search citations, per a 89K URL study
Google AI Max is replacing Dynamic Search Ads
Meta's Muse Spark brings AI shopping to Instagram and Facebook
58% of Google searches now end without a click

📬 Reply to this email: Where are you shifting ad spend this quarter, and why?

the signal

The biggest power shift in digital advertising in a decade just showed up in a forecast.

Meta Is About to Overtake Google in Global Ad Revenue. For the First Time Ever.

eMarketer projects Meta will capture 26.8% of global ad spend in 2026, edging past Google's 26.4%.

The Data: According to eMarketer's latest forecast, Meta will bring in $243.46 billion in global ad revenue this year. Google will land at $239.54 billion. That's a gap of nearly $4 billion in Meta's favor.

Last year, Google was still on top: $214.06 billion to Meta's $196.17 billion. The swing happened fast. Meta's ad revenue is growing at 24.1% year-over-year, up from 22.1% in 2025. Google is growing at 11.9%, roughly flat from last year.

The Context: Meta's acceleration is tied to a few things. Advantage+ campaigns have made it easier for advertisers to run AI-automated creative and targeting at scale. Reels adoption keeps climbing. And Meta's AI-generated ad creative tools are pulling budget from brands that used to split more evenly across platforms.

Google, meanwhile, is dealing with headwinds on multiple fronts: AI search is eating into traditional search ad inventory, the DOJ antitrust case is adding uncertainty, and advertisers are watching organic click-through rates fall as AI Overviews take up more real estate on the results page.

The Backstory: Amazon is worth watching here too. It's projected at $82.07 billion in 2026 ad revenue, up from $68.64 billion in 2025. Between Meta, Google, and Amazon, 3 companies will control roughly 60% of all global digital ad dollars. The concentration is getting tighter, and the balance of power within that group just shifted.

the breakdown

If the lead story is about where the ad dollars are going, this one is about where the citations are going. A new study maps exactly what gets picked up by AI search engines.

LinkedIn Is the #2 Most-Cited Source in AI Search. A New Study Shows What Gets Picked Up.

The Data: A SEMrush study of 325,000 prompts across ChatGPT Search, Google AI Mode, and Perplexity found 89,000 unique LinkedIn URLs cited in AI-generated responses. That makes LinkedIn the 2nd most-cited domain overall, trailing only Reddit, and #1 for professional and B2B queries.

The citation rates vary by platform: ChatGPT cites LinkedIn in 14.3% of relevant responses, Google AI Mode in 13.5%, and Perplexity in 5.3%. Between November 2025 and February 2026, LinkedIn climbed from #11 to #5 on ChatGPT's citation leaderboard. That's the largest authority shift the researchers observed in any domain.

What Gets Picked Up: Long-form articles between 500 and 2,000 words account for 50-66% of all LinkedIn citations. Shorter feed posts (50-299 words) make up 15-28%. The content that gets cited is overwhelmingly original: 95% of cited posts were original content, while reshares accounted for just 5%.

Knowledge-sharing and advice posts represented 54-64% of citations. Individual creators outperformed company pages on both ChatGPT (59% individual vs. 41% company) and Google AI Mode (59% vs. 41%). And 75% of cited authors had published 5 or more posts in the prior 4 weeks. Consistency matters.

The Takeaway: One finding stood out. Authors with fewer than 500 followers were cited at rates equal to or higher than those with 2,000+. That means the AI citation game rewards substance over audience size. The semantic similarity score between cited LinkedIn posts and the AI responses that cited them was 0.57-0.60, meaning the AI is closely mirroring the original language. If you write clearly about a specific topic, there's a real chance AI search picks it up and paraphrases you directly.

on the radar

More signals from the same theme: platforms retooling how ads get served, how products get discovered, and how clicks are disappearing.

Google AI Max Is Replacing Dynamic Search Ads (migration starts September 2026)

Google's AI Max campaign type is moving out of beta. Starting in September, Dynamic Search Ads will be migrated into AI Max, which uses broader intent signals, expanded keyword matching, and AI-generated ad copy. Google says campaigns using the full AI Max feature set are seeing an average uplift in conversions at similar cost efficiency. If you're running DSAs, the transition is coming whether you're ready or not. Source

Meta Launches Muse Spark — an AI shopping assistant headed to Instagram and Facebook

Meta's new AI model, Muse Spark, built by Meta Superintelligence Labs, can suggest outfits, style rooms, and recommend gifts based on conversational prompts. It's live in the Meta AI app now and expanding to Instagram Explore (with a "Search with Meta AI" tab) and Facebook in the coming weeks. Meta is also rolling out one-tap checkout and buy buttons directly in ads. The move turns Meta's AI from an ad-targeting engine into a full-funnel shopping assistant. Source

58% of Google Searches End Without a Click — and ChatGPT is becoming a transaction layer

Two data points that tell the same story. First: 25% of Google searches now trigger an AI Overview, with some categories hitting 48%. Organic CTR drops 15-47% when those overviews appear, and 58% of all Google searches now end without a single click to any website. Meanwhile, OpenAI is integrating brands like Target, DoorDash, and Spotify directly inside ChatGPT conversations, letting users transact without leaving the chat. Between zero-click search and in-chat commerce, the click itself is becoming optional. Source

Until Next Time

The ad dollar, the citation, and the click all moved this week. Where they land next depends on how fast platforms ship and how fast marketers adapt.

See you next week,
