If you’ve noticed a sudden drop in reported impressions in Google Search Console in September 2025, you’re not alone. Many websites have experienced this shift, which has caused confusion and concern. The good news is that this change is primarily related to how Google counts impressions, not necessarily a reflection of your site’s actual traffic.
In mid-September 2025, Google made a significant change to how impressions are tracked in Search Console. This update removed the ability to view 100 search results on a single page by eliminating the &num=100 parameter. This parameter had previously allowed SEO tools and automated scripts to access a broader set of search results, including those that were lower on the page or generated by bots. With its removal, Search Console now focuses on reporting impressions from higher-ranking results, leading to a noticeable decrease in reported impressions, especially for pages ranking lower.

The removal of the &num=100 parameter means that impressions are now counted only for search results that are more likely to be seen by users. As a result:
It’s important to note that this change is a reporting adjustment, not an algorithmic penalty. If your site’s traffic remains steady or continues to grow, this indicates that the update has not negatively impacted your SEO performance.
To accurately gauge your site’s SEO health in light of this update, consider the following steps:
