Understanding the Drop in Google Search Console Impressions
Recently, many SEOs have noticed a drop in impressions within Google Search Console (GSC). You might have seen shifts in average positions or a change in the number of reported queries. But before you panic, let’s break down what happened, why it matters, and why this change is actually a good thing for SEO professionals.
What Happened to GSC Impressions?
This drop isn’t due to a major ranking update, but a significant change in how Google reports data. In mid-September, Google quietly stopped supporting the &num=100 parameter, which previously allowed crawlers and third-party tools to retrieve up to 100 results per query. When this support was discontinued, many of the extra data points – including some impressions and positional averages – vanished from Google Search Console.
The good news? The search results themselves didn’t change. Google’s decision to stop supporting this parameter simply recalibrated the data to provide a more accurate representation of real user behavior. In short, it gave SEOs a clearer, truer picture of actual search visibility.
Why Does This Change Make Sense?
It’s time to reset how we interpret GSC impressions. Think of this change like simplifying a process for better efficiency. Similar to when you have fewer items at a garage sale, fewer choices lead to clearer, better results. By ending support for the &num=100 parameter, Google has focused on showing data based on real user activity rather than automated crawlers, which previously added noise to the data.
While this shift caused some disruption for third-party tools that relied on those extra data points, it ultimately aligns GSC data with what actual users are seeing. This means that the drop in impressions you’re seeing is likely a reflection of more accurate, real-world visibility.
The Alligator Effect: What Changed After September 12?
Earlier in 2025, a pattern emerged in GSC reports known as the “Alligator Effect.” This referred to the sharp increase in impressions that looked like an open alligator’s mouth, with steady clicks to match. While many attributed this to factors like AI Overviews or an increase in zero-click searches, it was actually a symptom of inflated data from automated crawlers.
After Google stopped supporting the &num=100 parameter in September, this “Alligator Effect” closed, and impressions returned to more realistic levels. The result? A more accurate baseline for measuring search visibility and performance.
What Does This Mean for SEO Reporting?
While it’s always been important to track impressions and average position, we now need to reconsider how we read these metrics. With the removal of crawler noise, GSC now provides a much clearer picture of what’s truly happening with your search traffic. This is a good thing for SEOs – it allows us to focus on the data that matters.
In conclusion, the drop in GSC impressions is not a cause for alarm, but rather an opportunity to recalibrate and gain a more accurate understanding of your website’s performance in search. By removing automated crawler noise, Google has made it easier to track true user engagement and visibility. Going forward, the data you see in GSC will reflect the reality of search activity – and that’s exactly what you want for effective SEO.
