This week brought continued fallout from December's core update, a major legal action from Google, and new data on AI citation patterns.

Here's our latest rundown of critical search updates.

Core Update Devastation Continues

SEOs are still reporting volatility, traffic, and ranking drops from the December 2025 core update, affecting sites across various niches with up to 40% traffic declines.

The severity is unprecedented for 2025, with some sites experiencing their worst rankings in years.

Major publishers and large platforms, including Quora, are especially being hit hard.

Her analysis shows that established platforms previously insulated from algorithmic changes are now facing significant visibility losses.

The data reveals that Google is fundamentally reshaping what content qualifies for top rankings.

Google Takes Legal Action Against SerpApi

Google is suing SerpApi for allegedly scraping and reselling copyrighted content from Search results by bypassing security protections.

The lawsuit marks the tech giant's most aggressive legal stance against data scraping services that monetize Search content.

SerpApi provides API access to Google Search results, allowing developers to extract data at scale without using official APIs.

Google says the practice violates copyright and circumvents safeguards meant to block automated scraping.

The case could set a precedent for how search engines protect their results from third-party extraction and resale.

AI Citations Favor Depth

New research shows that pages ranking for fan-out queries are 161% more likely to be cited in AI Overviews than pages ranking only for main queries.

Fan-out queries are the specific, related questions users ask after an initial broad search.

The finding suggests that content optimized for comprehensive topic coverage performs significantly better in AI search than narrowly focused pages.

However, Microsoft Bing warns that duplicate or similar content makes it hard for AI search engines to interpret intent signals.

Content consolidation and clear topical differentiation are becoming essential for AI search visibility.

Google's public liaison for Search, Danny Sullivan, also said that ranking systems, including AI search, reward content written for humans rather than algorithms.

This statement pushes back against tactics that optimize solely for AI discovery without considering user value.

YouTube Thumbnail Performance Varies

A study found that YouTube thumbnails with and without human faces perform about the same, with larger differences by niche.

Business-related videos show slightly better performance without faces, which challenges conventional wisdom about thumbnail optimization.

Google is also deleting reviews at record levels in 2025, with five-star reviews accounting for a sizeable share.

The aggressive removal of reviews aims to maintain authenticity and trust.

However, legitimate businesses have also reported seeing valid reviews disappear.

The SEO Community Weighs In

SEO specialist Daniel Foley Carter recommends focusing on technical review of websites, index cleanup, and content audits for 2026.

These priorities reflect the increasing importance of technical foundations as Google tightens quality standards.

Concurate also published a case study showing how deep research of user pain points and strategic content planning helped an SaaS company rank #1 globally.

The takeaway reinforces that planning content strategy around in-depth competitor analysis and user pain-point research delivers measurable results.

SEO consultant Matt Diggity, on the other hand, highlighted how search behavior is fragmenting across platforms.

This week's changes reveal multiple pressure points converging simultaneously.

The December core update is proving far more destructive than previous 2025 updates, forcing fundamental content strategy reassessments.

Google's legal action against SerpApi signals a harder line on data access and monetization of search results.

AI citation patterns are also creating new optimization requirements that go beyond traditional ranking factors.

For 2026, brands and agencies should respond with these moves:

• Audit content for fan-out query coverage to improve AI Overview citation likelihood by 161%.
• Eliminate duplicate or similar content that confuses AI intent interpretation.
• Develop platform-specific content strategies for Instagram, YouTube, ChatGPT, and LinkedIn outside of Google optimization.

The fundamentals remain critical, but execution standards are rising dramatically.

Our Take: Is This Google's Quality Reckoning?

The December core update suggests Google is making fundamental changes to quality evaluation and putting it before incremental adjustments.

Seeing major publishers and platforms like Quora take significant hits indicates Google is willing to devalue established authority when content doesn't meet new standards.

I suspect Google is forcing a quality reckoning, where brand names and domain authority matter less than actual content depth and user value.
