Impact of the Removal of &num=100 in Google Search URLs

When Google discreetly eliminated the “&num=100” parameter from its search URLs, it may have seemed like a minor technical tweak. Nevertheless, within just a few days, SEO experts and news publishers noticed their rank trackers and keyword visibility reports becoming irregular. This change has not modified how Google ranks content, but it has significantly influenced how those rankings are observed and analysed.

What Exactly Changed

For many years, appending “&num=100” to the end of a Google search URL allowed users and SEO tools to display as many as 100 results on a single page. Although it was never officially documented by Google, this became a popular shortcut for efficiently crawling search engine results pages (SERPs).

Since mid-September 2025, Google quietly deactivated this feature, reducing the number of results retrievable at once. Tools that depended on this method now require loading multiple pages to gather the same information, resulting in increased time and costs and, for many users, confusion.

Why It Matters to SEO Reporting

The elimination of “&num=100” has not altered actual search rankings or the way Google’s algorithm assesses content. Instead, it has transformed how SEO tools perceive these results. Rank trackers that used to acquire 100 results at once are now limited to a smaller set of results. The immediate outcome is a noticeable decline in reported keyword counts and search visibility metrics.

Many publishers, upon seeing sudden drops in visibility graphs, initially worried about possible ranking losses. However, this issue is more about measurement than about traffic or ranking declines. If the data from Google Search Console and Google Analytics remains stable, it suggests that actual performance has not waned.

Implications for News Websites

1. Decline in reported keywords

SEO dashboards that once showcased hundreds of ranking keywords per article may now reflect significantly fewer. This does not necessarily indicate a decrease in search reach, as long-tail keywords that appear on deeper pages are simply not captured in the same manner anymore.

2. Confusing visibility reports

Publishers might observe fluctuations in keyword visibility charts provided by third-party platforms. This does not represent audience behaviour but is rather a result of modifications in data collection methods.

3. Increased costs for SEO tools

Since scraping data now demands multiple page loads per query, tools will likely face higher operational expenses. Some vendors have already alerted users to potential pricing changes or a reduction in data frequency.

4. A reset for SEO strategy

This update serves as a pertinent reminder that not all metrics hold equal importance. For editorial teams, evaluating impressions, clicks, engagement, and conversions offers significantly more value than merely tracking keyword volumes.

How Newsrooms Can Adapt

Rely on first-party data

Google Search Console should be regarded as the primary source of truth. It accurately reflects genuine user impressions and clicks rather than approximate estimates from scraping.

Explain the context

When discussing reports internally, it is crucial to clarify that any decrease in keyword counts or visibility is a result of changes in data collection, rather than an actual drop in rankings.

Refine performance KPIs

Focus on metrics that illustrate meaningful audience behaviour like session duration, repeat visits, article engagement, and subscription conversions.

Collaborate with SEO vendors

Inquire with analytics partners about how they have adapted to this change and whether their reporting logic has been modified.

The Bigger Picture

Google’s decision to eliminate “&num=100” is part of a larger initiative to restrict extensive scraping and enhance control over how search data is accessed. While this presents challenges for SEO tool developers, it also nudges the industry towards cleaner, more user-focused measurement strategies. For news organisations, this moment calls for a reevaluation of what truly defines success in search—focusing on real readership attention and trust rather than simply the number of keywords detectable by a crawler.

The removal of the “Num 100” parameter signals a reporting revision rather than a ranking crisis. Publishers who grasp this distinction are equipped to move beyond panic and concentrate on what truly matters: delivering high-quality journalism that naturally performs well, irrespective of how tools visualise it.
