Data Collected

We analyzed keywords at the same point heading into Black Friday and Cyber Monday across both years to understand:

• Year-over-year changes in AI Overview deployment rates
• Pixel height changes (how much screen real estate AIOs consume)
• Category-level expansion patterns within eCommerce
• Before/during/after timing patterns around each holiday
• Search volume distribution across keywords with AIOs

Key Finding

Google expanded AI Overviews 3x more aggressively for Black Friday than Cyber Monday — and made them 65% larger year-over-year. The pattern reveals an intent-based strategy: AIOs dominate research moments (Black Friday) while traditional results still own purchase moments (Cyber Monday). Google isn't stepping aside for shopping anymore. They're leaning in — strategically.

The Year-Over-Year Expansion

Black Friday: +106% More Keywords with AIOs

Black Friday saw the most dramatic expansion. The number of keywords triggering AI Overviews more than doubled from 2024 to 2025.

This aligns with Black Friday's role as a research-heavy shopping moment. Consumers are hunting for deals, comparing options, and evaluating purchases. Google's AI Overviews are built for exactly this use case.

Cyber Monday: +37% More Keywords with AIOs

Cyber Monday saw meaningful expansion too — but at roughly one-third the rate of Black Friday.

Cyber Monday has evolved into a more transactional holiday. Shoppers have done their research; now they're ready to buy. Google's more conservative AIO expansion here suggests they recognize that traditional shopping results (carousels, PLAs, retail organic) better serve purchase-ready users.

The Intent Interpretation

The 3x expansion gap isn't random. It reflects Google's learning over the past year:

Research intent → Heavy AIO treatment (Black Friday mindset)

Purchase intent → Traditional results dominate (Cyber Monday mindset)

Google is matching SERP treatment to user intent, not just query volume or category.

The Size Shift: 65% More Screen Real Estate

Pixel Height Comparison

Black Friday AIOs averaged 826px in 2024 and grew to 1,368px in 2025 — a 65.6% increase.

Cyber Monday AIOs averaged 831px in 2024 and grew to 1,370px in 2025 — a 64.9% increase.

AI Overviews aren't just appearing on more keywords — they're consuming significantly more screen real estate when they do appear.

What This Means for Organic Visibility

A Position 1 organic ranking in 2025 sits roughly 540 pixels lower than the same ranking in 2024 — even if your actual position didn't change.

For context: 540 pixels is approximately half a standard desktop viewport. Content that was "above the fold" last holiday season may now require scrolling to reach.

The Q4 Trend

This wasn't a sudden holiday spike. Q4 2025 averaged 1,272px compared to Q4 2024's 823px — a 54.6% increase across the entire quarter. Google committed to larger AIOs heading into the shopping season and maintained that size throughout.

The Ramp-Up Pattern: Google's Pre-Holiday Expansion

2024: Flat Throughout November

In 2024, AI Overview pixel height remained remarkably consistent throughout the holiday shopping window. November 20 saw 821px, the day before Black Friday hit 832px, Black Friday itself was 826px, and Cyber Monday was 831px.

Variation of only ~10px across the entire period. Google appeared to be in testing mode — maintaining a steady presence without significant expansion.

2025: Deliberate Ramp-Up

2025 told a different story. Google progressively expanded AIO presence in the weeks leading up to Black Friday.

Four weeks before Black Friday, pixel height averaged 1,204px. Three weeks before, it grew to 1,298px. Two weeks before, it reached 1,307px. One week before, it hit 1,340px. During holiday week, it peaked at 1,371px.

That's a 14% increase in just four weeks — a clear signal that Google intentionally expanded AIO coverage heading into peak shopping.

The Strategic Implication

For 2026 planning: the optimization window may need to shift earlier. Content that earns AIO citations 3-4 weeks before peak shopping could establish presence before the real estate gets crowded. Waiting until November may be too late.

Category Expansion: Where Google Leaned In

eCommerce Share of AIOs Grew Significantly

On Black Friday, eCommerce's share of keywords with AIOs grew from 6.8% in 2024 to 10.1% in 2025 — a 35% increase. On Cyber Monday, it grew from 7.7% to 10.2% — a 32% increase.

Google didn't just expand AIOs overall — they specifically expanded coverage of shopping-related queries. eCommerce's share of the AIO pie grew by roughly one-third.

High-Volume Shopping Keywords

Keywords with 50,000+ monthly search volume that triggered AIOs grew from approximately 1.7% in 2024 to 2.7% in 2025 — a 59% increase in Google's willingness to serve AIOs on high-stakes, high-volume shopping queries.

The Categories That Saw the Biggest Expansion

TV & Home Theater saw the most dramatic growth at +242% for Black Friday and +57% for Cyber Monday. Electronics followed with +75% for Black Friday and +44% for Cyber Monday. Small Kitchen Appliances grew +43% for Black Friday and +42% for Cyber Monday.

These are core gift categories — and exactly where shoppers do the most research before purchasing. Queries like "best 65 inch tv," "ninja vs vitamix," and "top chromebooks" now live in AIO territory.

What Stayed Flat

Apparel saw slight contraction (-4% to -9%) and Home Furnishings declined (-29% to -30%). Google appears more aggressive with AIOs in categories where research and comparison shopping dominate, less aggressive where visual browsing and personal taste drive decisions.

The "No Pullback" Finding

Did Google Step Aside During Peak Shopping?

One theory heading into 2025 was that Google might reduce AIO presence during actual shopping days — letting transactional results take over when users are ready to buy.

The data says otherwise.

Black Friday 2025 Timing Distribution

Keywords with AIOs were distributed almost perfectly across the window: 33.3% the day before, 33.3% on Black Friday itself, and 33.4% the day after. Google maintained consistent AIO presence throughout the shopping window — no pullback during the peak.

Cyber Monday 2025 Timing Distribution

Same pattern: 33.5% the day before, 33.4% on Cyber Monday, and 33.2% the day after. Google isn't temporarily stepping aside for shopping moments anymore. AIOs are a persistent feature of the shopping SERP.

What Google Learned (And What It Means)

The 2024 Testing Phase

Last year's flat pixel heights and moderate expansion suggested Google was still experimenting — testing where AIOs helped users and where they got in the way.

The 2025 Commitment

This year's data shows Google has reached conclusions:

AIOs help shoppers research. The massive Black Friday expansion (research mode) vs. moderate Cyber Monday expansion (purchase mode) shows Google matching AIO presence to intent.

Bigger AIOs don't hurt engagement. The 65% size increase suggests Google's internal metrics support larger AI-generated content blocks for shopping queries.

Category matters. Electronics, appliances, and TV/home theater saw aggressive expansion. Apparel and furnishings didn't. Google is selective about where AIOs add value.

Timing matters less than expected. No significant pullback during peak shopping days means AIOs are now a permanent fixture, not a situational feature.

Strategic Implications for Brands

Two Metrics Now Matter

The old model: track your rank position, measure traffic.

The new model: track two different metrics depending on query intent.

For research queries (Black Friday mindset): Track citation share in AI Overviews and visibility within AIO content. These queries saw the heaviest AIO expansion.

For purchase queries (Cyber Monday mindset): Track traditional rank position, Shopping carousel presence, and PLA performance. These queries saw more conservative AIO growth.

Same content calendar. Different success metrics depending on intent.

The Optimization Window Shifted

2024: Optimize in November, compete during peak shopping.

2025+: Optimize in October (or earlier), establish AIO presence before the ramp-up begins.

Google's 14% pre-holiday expansion suggests that waiting until the shopping season to optimize for AIOs puts you behind brands who started earlier.

Category-Specific Planning

If you're in TV/Electronics/Small Appliances: AIOs are now a major part of your competitive landscape. These categories saw the biggest expansion — TV & Home Theater grew +242%, Electronics +75%, and Small Kitchen Appliances +43%. Plan for AIOs as a persistent SERP feature.

If you're in Apparel/Home Furnishings: AIOs expanded less aggressively — Apparel contracted slightly and Home Furnishings declined significantly. Traditional SEO may still deliver more impact than AIO-specific strategies in these categories.

Key Takeaways

The Expansion Gap: Black Friday saw +106% more keywords with AIOs YoY; Cyber Monday saw +37%. Google expanded 3x more aggressively for research moments than purchase moments.

The Size Shift: AI Overviews grew 65% larger YoY (~826px → ~1,368px). Same rankings now mean less visibility above the fold.

The Ramp-Up Pattern: 2025 showed a 14% increase in AIO pixel height in the 4 weeks before Black Friday. 2024 was flat. Google now deliberately expands heading into peak shopping.

The Category Story: TV & Home Theater (+242%), Electronics (+75%), and Small Kitchen Appliances (+43%) saw the biggest AIO expansion. Core gift categories are now AIO territory.

The No-Pullback Reality: Google maintained consistent AIO presence before, during, and after both holidays. No stepping aside for peak shopping.

The Intent Strategy: Google matches AIO presence to user intent — heavy for research, lighter for purchase. Your metrics should do the same.
