A comprehensive, data-driven analysis of the recent Google search changes, the measurable impact on organic traffic and rank trackers, and precise actions you can take now to protect traffic and future-proof your SEO.
Note: As of August 2025 Google has removed the ability to show the top 100 results with the “&num=100” URL parameter.
This is ultimately to reduce the impact of AI search crawls on their cost centres from bulk scraping SERP results.
This means that pagination will become a massive barrier for rank trackers which will ultimately increase costs substantially and for some render them completely obsolete.
1. What happened and why it matters
Over the last 18–24 months Google has pushed several structural changes to how search works: major AI summary features (SGE / AI Overviews), expanded personalization and localisation, more aggressive SERP features (knowledge panels, carousels, video/YouTube placements), and deliberate limits/sampling to the query data available through Search Console. The net result: fewer clicks to the open web, more “answers on the SERP,” and greater variability between what a rank tracker reports and what real users see.
This isn’t theoretical, multiple independent studies and traffic panels show significant declines in clickthrough and pageviews for affected categories. Zero Click Search Study – Spark Toro
2. The concrete changes Google made
A. Search Generative Experience (SGE) / AI Overviews
Google has deployed generative AI answers in SERPs (branded SGE / AI Overviews). These summarise content from multiple pages and present an answer directly in the results page, often above organic links, reducing the need for users to click through. Early empirical research shows SGE can remove or reduce clicks to links that would previously have captured traffic. Search Generative Experience – Authoritas
B. Growing zero-click searches
Independent panel studies show that a large and growing share of queries end without a click (i.e., the user gets what they need from the SERP itself). Recent analyses place zero-click rates at or near ~60% for many query sets. Zero Click Search Study – Search Engine Land
C. More SERP self-preference & trademarked features
Google increasingly surfaces its own properties (Maps, Shopping, YouTube) for a range of queries, creating fewer opportunities for a third-party site to capture the top CTR. Zero Click Search Study – Search Engine Land
D. Removal Of Top 100 Results For Rank Trackers
With the removal of the “&num=100” URL parameter to reduce the impact AI has on Google’s cost centres and the SEO world as a whole rank tracking has taken a massive hit. Critical Updates to Depth Parameter – DataForSEO
E. More personalization & localisation
Search results differ more dramatically by user: location, search history, device, and logged-in state now change rankings and results composition more than before, so a single “global” rank is less meaningful. Personalized Search Explained – LinkAssistant
F. Search Console data sampling & limitations
Google Search Console (and the API) now surfaces sampled or partial query data in many cases; you may no longer see every query impression/click in the UI or API. That makes historical comparisons and granular keyword-level tracking more complex. Search Query Details – Google for Developers
G. Ongoing core updates & algorithm refinements
Google’s regular core updates continue to change ranking weightings (E-E-A-T, topical authority, UI signals). These updates compound the visibility impact when the SERP also features AI summaries. What Is A Core Update – Google for Developers
3. Hard data: datasets that corroborate page-view drops
Below are the most important independent data points available publicly:
- SparkToro zero-click study (2024): SparkToro’s panel shows a substantial proportion of searches end without a click to the open web (their large-panel research is a reliable, repeated signal). This is a key indicator of diminishing organic CTR for non-owned content. Zero Click Search Study – Spark Toro
- Search Engine Land / industry studies on SGE: Several industry analyses, including tests run on hundreds to thousands of queries, show SGE examples where top organic result clicks are materially reduced when the AI summary appears. Some SE tests modelled traffic loss and recommended mitigation tactics. How Google SGE Will Impact Your Traffic – Search Engine Land
- SimilarWeb / news traffic decline (May 2025): Digital intelligence panels show large drops in organic pageviews for news domains after AI Overviews were widely introduced, Some publishers saw year-over-year declines in organic visits measured in the hundreds of millions. (See SimilarWeb/TechCrunch reporting and subsequent media coverage.) Google AI Summaries Increase Frequency Of ‘Zero Clicks’ – New York Post
- Authoritas SGE experiments: Controlled experiments by analytics firms found that pages which previously ranked #1 lost a large proportion of traffic for queries where AI Overviews replaced or preempted the organic link. The study suggests losses can be very large for specific term sets. Impact Of Google’s Search Generative Experience – Authoritas
- Search Engine Journal vertical impact analysis: SEJ’s vertical breakdown shows SGE’s effect varies by industry: transactional & local queries hold up better; broader informational and news queries are most affected. SGE Organic Traffic Impact By Verticals – Search Engine Journal
Quick takeaway: the datasets converge on the same theme: if Google gives an answer in the results, users click less. For some publishers this is a marginal effect; for others (news & informational publishers) it is a material, revenue-impacting drop.
4. Why rank trackers are less reliable today
Rank trackers were designed for a world where search results were fairly static and reproducible for a given query/location. Today, that assumption breaks down.
Key reasons rank trackers fail now:
- Personalisation & session signals – one person in Sydney will see a different result set than another in the same suburb if their browsing history and account activity differ. Rank trackers using a single IP / single simulated user do not capture this spread. Personalized Search Explained – LinkAssistant
- SERP volatility and mixed formats – the presence of AI Overviews, People Also Ask, carousels, and video sections means a page can be on “page one” but off-screen or below the fold, making position less meaningful. How Google SGE Will Impact Your Traffic – Search Engine Land
- Sampling & data obfuscation from Google – Search Console and its API are sampled for some queries; rows are limited, so the granular signals rank trackers once used to validate performance may be incomplete. Search Query Details – Google for Developers
- SERP snapshots vs live experience – many trackers capture a single screenshot or API result at a moment in time. But modern SERP composition can change with follow-up queries and multi-turn interactions (especially when AI overviews are interactive). Googles SGE Is Here – EnFuse Solutions
Result: a single rank number per keyword is now frequently meaningless. You need distributional visibility (how often are you appearing in any material form for a query across locations/devices/contexts), not just a nominal rank.

6. Tactical playbook: what to do right now (step-by-step)
Below are practical actions divided into Immediate (next 30 days), Short term (30–90 days), and Medium term (3–12 months).
- Audit SERP coverage, not just ranks
- Use a multi-location SERP snapshot tool (desktop & mobile) to capture all variations for top keywords across major metro areas. Track who is shown in AI Overviews, knowledge panels, video carousels, and local packs. Tools: SEMrush Sensor / Ahrefs SERP, RankRanger, API screenshots. Future Of Rank Tracking – Ranktracker
- Review Search Console & GA4 for signal changes
- Look for drops in impressions, average position spread, and top landing pages; cross-reference with external panels (SimilarWeb / analytics) to validate. Be mindful Search Console can be sampled, don’t rely on it alone. Search Query Details – Google for Developers
- Protect high-value transactional pages with paid
- For pages that drove revenue, allocate immediate PPC budget to maintain lead volume during organic volatility.
Short Term Steps (30–90 days)
- Optimize to be quoted in AI Overviews
- Schema markup & fact boxes
- Use FAQ schema, HowTo schema, and data-rich schema types to increase the chance your content is used as a source. This does not guarantee inclusion, but increases machine readability. How To Rank In Google’s SGE – Docommunication
- Capture first-party channels
- Launch or upscale email capture (content upgrades, exit intent modals), push notifications, and SMS flows. First-party traffic is now insurance against zero-click volatility. Goodbye Clicks – Bain
- Experiment with short-form video & audio
Medium Term Steps (3–12 months)
- Topical authority and original research
- Brand and knowledge panel strategy
- Server-side tracking & first-party data pipelines
- Implement server-side analytics & CRM integrations to reliably measure conversions and tie them back to channels even when client-side signals decline (cookie loss, CTR sampling). Use offline conversion imports for ad platforms. Search Query Details – Google for Developers
- Diversify acquisition
- Invest in partnerships, direct referral programs, affiliates, and social commerce. Redundancy reduces dependency on a single source.
- Negotiate content licensing / republishing deals
- For publishers, consider deals to syndicate or license content to aggregator platforms (or at least secure payment terms if your content is used in AI summaries).
7. How to measure success once you act
Shift KPIs away from raw organic pageviews alone. New KPIs to track:
- Brand mentions in AI Overviews – use SERP scraping to detect when your domain is cited or used by AI summaries. (Some monitoring tools are emerging.) 7 Smart Ways To Keep Ranking In AI Powered Search – EnFuse Solutions
- Share of voice in SERP features – percentage of times you appear in People Also Ask / Knowledge panels / Featured Snippets / Video spots. Future Of Rank Tracking – Ranktracker
- First-party retention metrics – email signups, repeat visits, push opt-ins.
- Direct conversions & offline attributions – bookings, calls, stored in CRM.
- Revenue per user (instead of pageviews) – to prioritise high-value interactions.

10. Conclusion: the new rules of search
Google’s changes, AI Overviews/SGE, heavier personalization, and SERP feature proliferation, are not tiny tweaks. They change how people discover and whether they click. Rank trackers still have a role, but their output must be reinterpreted: a rank is one signal among many, not the final word.
The winning response is twofold:
- Technical and content optimisation to be machine-readable and machine-friendly (structured data, precise answer blocks, authority signals), and
- Audience ownership through first-party channels and diversified acquisition (email, video, partnerships, paid defence).
If your org treats SEO as traffic chasing a single metric, you will lose. If you treat SEO as one component of an integrated audience & brand strategy, optimised for both humans and AI citations, you’ll gain the resilience to thrive in this next era of search.
