Google Increases Link Density in AI Overviews and AI Mode
In a move aimed at addressing publisher concerns over traffic decline, Google has begun displaying more links within its AI Overviews and AI Mode interfaces. This update, noted in recent SEO news roundups from early September 2026, is designed to surface more relevant websites, original content, and firsthand perspectives alongside the generated answers. For publishers, this represents a potential mitigation strategy against the "zero-click" phenomenon, although the long-term impact on referral traffic remains under observation.
Perplexity Trips Revenue to $750M Amid Agent Pivot
Perplexity AI has reported a significant financial milestone, with its annualized revenue tripling to $750 million. This growth is attributed to a strategic pivot toward agent-based capabilities rather than just search, a shift that has reportedly attracted serious interest from Nvidia for potential investment. The company’s evolution from a simple search engine to a complex workspace tool highlights the changing competitive landscape of AI answer engines.
Debate Intensifies Over Tracking Perplexity Visibility
A new analysis suggests that giving Perplexity less weight in AI search tracking may be prudent for many businesses. As ChatGPT, Gemini, and Claude lead in overall AI visibility, focusing resources on Perplexity might distort visibility scores without providing proportional business value. This recommendation reflects a maturing market where brands are becoming more selective about which AI platforms they optimize for, prioritizing those with higher user engagement and conversion rates.
Le Monde Reports No Audience Drop from AI Overviews
Contrary to widespread fears, French newspaper Le Monde has stated that its audience has not declined since the launch of Google's AI Overviews in France. The publisher attributes this stability to strong app traffic and subscriber growth, which have offset any potential losses from search referrals. This case study adds nuance to the global narrative about AI search decimating publisher traffic, suggesting that brand strength and direct audience relationships can provide a buffer.
Local view
While no specific local-language media reports from non-English speaking regions were available in the past week's data, global outlets like Search Engine Journal and Fast Company continue to drive the primary discourse. The Le Monde report serves as a key European perspective, challenging the U.S.-centric narrative of catastrophic traffic loss.
Context & numbers
- Perplexity Revenue: Tripled to $750 million annualized revenue.
- Zero-Click Searches: Data from Similarweb (referenced in July 2026 reports but still framing current trends) indicates zero-click searches rose from 56% to 69% between May 2024 and May 2025.
- AI Referral Traffic: Currently accounts for only 1-3% of sessions on most B2B SaaS sites, highlighting the limited immediate impact on direct web visits compared to traditional search.
On the radar
- Publisher Licensing Models: Mid-market publishers are increasingly relying on crawler control and Rights Protection Services (RPS) as they struggle to secure individual licensing deals that are typically reserved for large entities.
- EU Antitrust Complaints: The European Publishers Council's formal antitrust complaint against Google over AI Overviews and AI Mode remains active, potentially influencing future regulatory requirements for AI search transparency.
