It’s Not a Traffic Crash.
Many site owners noticed a sharp drop in impressions in Google Search Console starting in October 2025. While it looked like traffic had fallen, the change is actually the result of an update in how Google reports data, along with a few recent algorithm changes.
Changes in Search Console Reporting
In late September 2025, Google updated how impressions are counted in Search Console. The change involved removing the &num=100 parameter, which previously allowed users and SEO tools to view up to 100 results per page.
Because of this adjustment, impressions are now recorded differently. The result is a visible decline in numbers beginning in October — not because visibility dropped, but because impressions are being counted more accurately.
This update also helped clean up the data by filtering out non-human traffic, such as bots and scrapers. In short, the numbers you see now better represent real user activity.
What to Focus on Instead
Impressions might look lower, but that doesn’t mean performance has suffered. Metrics like clicks and click-through rate (CTR) weren’t affected by the change. These figures still reflect genuine user interactions and are a more reliable way to measure search performance.
Algorithm Updates That Played a Role
In addition to the reporting change, a few recent algorithm updates have influenced how sites are performing in search.
August 2025 Spam Update
This update finished rolling out in late September and targeted low-quality or manipulative content. Sites relying on thin content, spammy tactics, or keyword stuffing often saw a drop in rankings and traffic.
AI Overviews and Zero-Click Searches
Google’s expansion of AI-generated overviews has changed user behavior. More searchers now find answers directly on the results page, reducing the need to click through to websites. Even if a page is cited in these overviews, it can still receive fewer visits.
Other Contributing Factors
While the reporting change is the main cause, several other factors can influence fluctuations in search data:
- Competition: A competitor’s improved content or SEO strategy can push your rankings down.
- Seasonal patterns: Normal shifts in search interest throughout the year can cause dips in traffic.
- Technical issues: Problems like slow site speed, downtime, or indexing errors can reduce visibility.
Final Takeaway
The drop in Google Search Console impressions seen in October 2025 isn’t a true loss of traffic. It’s the result of Google refining how it reports data and the impact of ongoing algorithm updates.
Focus on the metrics that matter — clicks, CTR, and engagement — to get a clearer view of how your site is really performing.
