In the autumn of 2025, the SEO industry experienced a quiet but far-reaching change: Google stopped allowing URL query parameters such as &num=100 or n=100 to display 100 search results on a single results page.
For years, this parameter had made it easier for SEO tools, crawlers, and reporting systems to retrieve up to 100 search results through a single query. Google’s decision to change this behaviour without a major public announcement forced many organisations to reconsider not their actual search performance, but the way their SEO data is collected, interpreted, and reported.
What Does This Mean?
From a data perspective, one point is particularly important: this change does not necessarily indicate a loss in SEO performance. Instead, it can create a break in reporting and measurement continuity.
The way deeper search results were previously retrieved and processed has changed. For SEO teams and agencies, this creates three important implications:
- You may see declines in reports — but this does not automatically mean that traffic or rankings have fallen.
- Average position may appear to improve because deeper-ranking results may no longer be captured in the same way.
- Rank-tracking and SERP analysis tools may need to make more requests to retrieve the same depth of results, potentially increasing processing time and data acquisition costs.
The Impact on SEO Strategy
- The focus of visibility reporting may need to change:
First-page visibility becomes even more important from a reporting perspective. Rankings on pages two or three may be less consistently represented depending on the tool and collection method being used. - Reporting methodologies should be reviewed:
Instead of relying heavily on a single visibility metric, teams should evaluate SEO performance using a broader set of indicators such as click-through rate (CTR), traffic by keyword or landing page, organic sessions, and conversions. - The way SEO tools operate is changing:
Rank-tracking platforms that previously collected up to 100 results in a single request may now need to use multiple queries. This can require renewed planning around efficiency, tracking depth, API usage, and cost. - Client communication becomes even more important:
If reports show sudden changes, agencies should explain proactively that the underlying cause may be a change in data collection methodology rather than an actual decline in rankings or organic performance.
Practical Steps to Take
- Establish a new reporting baseline:
Consider creating a new baseline using data collected after September 2025. Direct comparisons with earlier periods may be misleading if the underlying collection methodology has changed. - Review your content priorities:
Continue investing in long-tail keywords and content aligned with genuine user intent. Visibility should not be evaluated only through rankings; engagement and business outcomes also matter. - Diversify your reporting metrics:
Combine impressions with clicks, organic sessions, conversions, engaged sessions, landing-page performance, and other quality-focused KPIs. - Review your rank-tracking configuration:
Reassess whether you genuinely need to track the top 10, top 20, top 50, or top 100 results for every keyword. Greater tracking depth can increase data collection requirements without always delivering proportionate strategic value. - Communicate transparently with clients and stakeholders:
If a reporting metric declines because of a structural change in how search results are collected, explain the context clearly. A change in reported visibility does not necessarily mean that the website itself has lost performance.
Google’s removal of the &num=100 behaviour is reshaping parts of the SEO reporting ecosystem.
Rather than being simply a technical adjustment, the change highlights a broader evolution in the measurement paradigm of SEO.
SEO professionals increasingly need to move beyond asking only:
“Where do we rank?”
and instead focus on questions such as:
- Which queries are generating meaningful traffic?
- Which landing pages are contributing to conversions?
- How effectively are users engaging with organic search results?
- Which areas of organic visibility are creating measurable business value?
Brands and agencies that adapt their reporting structures quickly can separate genuine performance changes from measurement-related fluctuations and make more reliable strategic decisions.
As always, the key point is not that the data has disappeared — the way we interpret and collect it has changed.
With the right methodology, that change can become an opportunity to build a more accurate, outcome-focused SEO measurement framework.
Our SEO team can help your brand monitor changes such as these, adapt reporting structures, and implement the necessary optimizations to maintain reliable and sustainable organic performance.
