Google Gave, and Google Has Taken Away
- Google Just Collapsed the Internet’s Middle Class By removing the &num=100 parameter, Google effectively erased 90 % of all measurable search visibility. Rankings beyond page one no longer appear in analytics, destroying the discoverability lifeline for mid-tier and smaller brands that lived off long-tail searches. 
- The SEO Economy Is Now Winner-Takes-All A brand in position #1 captures more than twice the visibility of #10, while anything past page one is statistically irrelevant. SEO tools are scrambling under 10× higher crawl costs, and marketers are being forced to abandon impression vanity metrics for performance metrics, CTR, CVR, and LTV. 
- Owning Distribution Is the Only Defense With organic reach throttled, survival depends on controlling your own audience pipelines—newsletters, social channels, ad networks, and direct data loops. In the post-num=100 world, whoever owns distribution owns discovery. 
In September 2025, Google quietly erased a 20-year-old pillar of SEO, the &num=100 parameter. No press release. No dev blog. No warning to the industry.
That single variable, which allowed marketers and analytics platforms to retrieve up to 100 results per search query, was eliminated overnight. Now, every Search Engine Results Page (SERP) caps at 10 results. Period.
At first, it seemed minor, just another tweak in Google’s endless algorithmic fine-tuning. But by week two, dashboards worldwide were in free fall.
The Numbers Behind the Panic
When the dust settled, 87.7% of indexed sites saw impressions in Google Search Console
drop dramatically. But actual clicks and traffic remained stable.
That discrepancy revealed something big:
It wasn’t audience behavior changing; it was visibility accounting itself that broke.
Average position data “improved” by up to 20%, simply because Google stopped including positions beyond page one in its calculations. In effect, the middle of the internet, positions 11 through 100, had vanished from Google’s field of view.
And that vanished middle wasn’t trivial. It represented:
- Tens of billions of long-tail searches monthly 
- Thousands of SMBs who lived off non-page-one discoverability 
- A quarter of global SEO spend devoted to “page 2–5 growth” strategies 
When those metrics disappeared, they didn’t just break dashboards, they broke business models.
How the “Num = 10” Update Broke the SEO Economy
1. Search Console Reality Distortion Brands that once celebrated 100K monthly impressions now see half that. Average rank position jumps artificially. Analysts scramble to explain why “visibility” plummeted while revenue didn’t. The answer: Google simply stopped showing you the parts of the ocean where you still swim.
2. The Tool Collapse Platforms like SEMrush, Ahrefs, and Moz were built on the &num=100 query framework. Now, to replicate a single 100-result scrape, they need ten paginated requests. That means 10× the data costs and slower refresh cycles. Some have resorted to truncating rankings beyond the top 20 as “20+,” introducing blind spots across entire industries.
3. The Vanishing Middle Tier SEO had an economic “middle class”, content sitting between rank 11–50 that fueled discoverability, brand lift, and incremental conversions. It’s gone from analytics entirely. As one agency executive put it:
If your content’s not in the top 10, it might as well not exist.
4. Page-One Arms Race Competition for those ten slots has become ruthless. A September 2025 visibility study found that a brand in position #1 enjoys over 2.2× the visibility of one in position number ten (10), and 0.0× for anything beyond page one.
The result: a bidding war for backlinks, authority, and paid amplification, all to win a few square inches of digital real estate.
5. The SMB Apocalypse Smaller and emerging brands are the collateral damage. Their long-tail content, the “how-to,” the “near me,” the “best X for Y”, no longer gets algorithmic sunlight. With AI overviews pulling answers from the same ten sources, these smaller entities are effectively erased from both organic listings and generative AI responses.
What the Data Really Says
| Metric | Before &num=100 Removal | After &num=100 Removal | Δ (Sept 2025) | 
| Avg. Impressions (GSC) | 100% baseline | −40–60% | ▼ 50% | 
| Avg. Clicks | 100% baseline | ± 3% | ≈ 0% | 
| Avg. Position (Top 100) | 38.5 | 17.2 | ↑ 55% | 
| SMB Visibility Index | 1.00 | 0.62 | ▼ 38% | 
| Rank Tracking Costs (Tools) | 1× | 10× | ↑ 900% | 
These figures, aggregated from Semrush, Search Engine Land, and independent agency studies, confirm a hard truth: Google didn’t destroy traffic, it destroyed measurement and fairness.
The Strategic Fallout
SEO teams are suddenly blind beyond page one. C-suites are being misled by prettier metrics masking flat growth. Tool vendors face margin collapse under higher crawl costs.
SMBs are losing visibility that once fueled 80% of their organic lead flow. And big brands, with multimillion-dollar authority footprints, are consolidating their dominance.
It’s not an algorithm update. It’s an economic reallocation of attention.
The Shift in Metrics: Vanity vs. Value
For years, marketers obsessed over impressions. But with Google now limiting what “counts,” those metrics are meaningless.
The only numbers that matter now:
- CTR (Click-Through Rate): Human attention, not crawler impressions. 
- CVR (Conversion Rate): Real outcomes tied to intent. 
- LTV (Lifetime Value): Post-click economics, not surface-level reach. 
- Revenue per Impression: The real proxy for visibility ROI. 
Those who pivot fast, from impression-based dashboards to value-based pipelines, will outpace slower competitors by quarters, not years.
Aligning with AI Search: The Next Frontier
Google’s own direction is clear: AI overviews and entity-based search. When users ask questions, the answer often comes directly in the SERP. Only a handful of cited sources appear, and those citations overwhelmingly favor entity-rich content.
That means every brand must:
- Structure pages with schema markup and clear entities (people, places, products). 
- Prioritize authority and verifiable expertise (E-E-A-T signals). 
- Optimize content for AI visibility, not keyword stuffing. 
Those who do will surface in AI overviews, the new “position zero.”
The Ownership Solution: Distribution as the Moat
If Google controls the discovery layer, brands must control the distribution layer.
Owning distribution means:
- Your own content network (YouTube, podcast, newsletter, owned blog). 
- Your own ad stack (first-party audiences, retargeting loops). 
- Your own analytics (independent data pipelines that don’t break when Google sneezes). 
- Your own amplification channels (social syndication, influencer pipelines, affiliate partnerships). 
This is where key partnerships with full-stack AI-augmented distribution models like iA and Janson's comes in. By fusing creative production with proprietary distribution infrastructure, spanning ad networks, newsletters, MCNs, and AI-optimized pipelines, brands under this umbrella bypass Google’s dependency trap.
In the Num = 10 era, distribution ownership equals algorithmic immunity.
The Five-Step Brand Playbook
- Audit Your True Visibility Ignore GSC impressions. Use direct traffic, AOR-tracked and managed data, and social analytics to map your actual exposure. 
- Reallocate SEO Spend Cut budget from deep keyword tracking and reinvest into first-page dominance and brand authority building. 
- Rebuild Your Distribution Stack Build owned channels: email, content hubs, and paid retargeting loops. 
- Entity-Proof Your Content Tag everything, products, founders, geographies, data points. AI indexes entities, not adjectives. 
- Partner with Distribution-Owning Agencies Agencies like iA + Janson don’t just market content, they deliver audiences. They guarantee reach when Google limits visibility. 
The Takeaway
Google didn’t just kill the &num=100 parameter. It killed the illusion of equal opportunity in search.
In this new world, SEO isn’t about climbing ten pages, it’s about securing one. And the brands that thrive won’t be the ones who chase the algorithm. They’ll be the ones who own the pipes the algorithm can’t touch.
Because when the window shrinks to ten, whoever controls distribution controls discovery.
TWR. Last Word: "Google didn’t kill SEO; it revealed that attention was never earned, only rented, and now brands that own distribution and serve audiences directly own the future."

Terms + Vocabulary
&num=100 Parameter
A URL variable Google previously allowed to retrieve up to 100 search results in a single query. Its removal in 2025 limits all SERPs (Search Engine Results Pages) to 10 results, fundamentally reshaping data visibility and SEO tracking.
Num = 10 Change / Update
Industry shorthand for Google’s September 2025 decision to restrict SERPs to 10 results. It disrupted rank-tracking software, skewed analytics, and erased mid-tier keyword visibility.
SERP (Search Engine Results Page)
The list of websites displayed after a user performs a search. Traditionally included 100 positions; now, only 10 standard organic results.
GSC (Google Search Console)
Google’s official reporting platform for web performance. Metrics such as impressions and average position became unreliable after the Num = 10 change.
Impressions
The number of times a page appeared in search results. Post-update, this metric dropped sharply—not due to traffic loss, but due to reduced data capture beyond page one.
Clicks / CTR (Click-Through Rate)
A measure of how many users clicked a result versus how many saw it. Now the most reliable indicator of real visibility, replacing impressions as a success metric.
AI Overviews / Generative Search
Google’s AI-driven summaries that present synthesized answers above traditional results. They source from “entity-rich” pages—those with structured, authoritative information.
Entity-Rich Content
Pages containing clearly defined data about people, products, places, or organizations, marked with schema and contextual signals. Favored in AI Overviews.
SEO Tool Crawl Limitations
Constraints faced by third-party platforms like SEMrush and Ahrefs after losing access to &num=100. To replicate old datasets, they must make 10× more requests, increasing cost and latency.
Visibility Index
An aggregate measure of a site’s overall presence across all tracked keywords. Most mid-tier and SMB websites saw 30–50 percent drops post-update.
Mid-Tier Content / The Internet’s Middle Class
Pages ranking 11–100 for keywords—previously responsible for incremental organic traffic. Now invisible to analytics and AI summaries.
Algorithmic Volatility
Rapid, often opaque changes to ranking systems that can erase visibility overnight. The Num = 10 update is a textbook case.
Distribution Ownership
The strategy of controlling audience reach directly—through owned newsletters, ad networks, influencer channels, and podcasts—rather than relying solely on search algorithms.
Platform Independence
A brand’s resilience against major algorithm changes by cultivating first-party data, direct traffic, and multi-channel distribution pipelines.
Performance Metrics vs. Vanity Metrics
A paradigm shift in measurement: valuing CTR, conversion, and LTV (Lifetime Value) over impressions or rank positions.
First-Party Audience Data
Information collected directly from customers (email lists, app usage, transactions). Key to maintaining targeting and measurement accuracy amid SEO instability.
Page-One Strategy
An SEO approach focused exclusively on ranking in the top 10 results—now the only positions with meaningful exposure.
