Google Search Console Impressions Drop | September 2025 Update

TL;DR – Why Impressions Dropped in Google Search Console

In mid-September 2025, Google Search Console data shifted in a way that not many website owners expected.

We saw Google Search Console impressions drop, while average positions improved.

Don’t panic — this isn’t a traffic collapse.

Google removed the &num=100 parameter that bots and scrapers used to view 100 results (or 10 pages on Google search) per query. That inflated impression counts in the past, even for rankings buried on page 9.

Now we’re seeing cleaner, human-centric data.

I’ve already seen this with clients: one lost nearly 10,000 daily impressions overnight, but clicks stayed steady, CTR improved by 1%, and their average position jumped from 26 → 15 over the last week.

Another client now averages position 10 instead of 20+.

Bottom line?

Your SEO isn’t broken. The data is just more accurate.

What Caused the Google Search Console Impressions Drop?

Around September 9–10th, 2025, Google removed the old &num=100 parameter that allowed bots and SEO tools to scrape the top 100 search results at once.

Why does that matter?

Because every time those bots ran a query, Google Search Console counted an impression — even if your site was sitting at position 87.

No real person was ever scrolling that far, but your report still showed “visibility.”

Now that the parameter is gone:

• Desktop impressions (where most scrapers operate) have plummeted
• Average position has improved (since those “page 9” impressions don’t count anymore)
• Clicks haven’t changed at all

In short: this is a data cleanup, not a penalty to you, or your site.

Why Rankings Improved Despite the Impressions Drop

As the September anti-spam Google update rolled out, there weren’t many people certain on what was going to happen.

However, they aren’t just theories anymore.

I’ve reviewed live Search Console data for multiple clients and here’s what we saw:

• Client A: Daily impressions fell by nearly 10,000, but clicks stayed steady. Average position improved from 26 → 15. CTR went up by a full percentage point.
• Client B: GSC Impressions dropped significantly, but their average position is now 10 (from high teens/20s). CTR also climbed.
• **Client C: **Google Search Console Impressions dropped by 35%, but their average position has now ranked inside the top 10 for the last 7 days.

Across the board: Traffic didn’t fall. Leads didn’t dry up. It’s only the metrics that shifted.

Clients were understandably curious when they saw impression graphs falling off a cliff.

But once I explained that most of those impressions came from bots, not humans, it was actually a relief.

They realized their sites weren’t invisible.

If anything, their data was finally telling the truth.

How the Google Search Console Update Affects Your SEO Reporting

• Year-over-year comparisons are now tricky. September 10, 2025, is a “data reset point.” Impressions before that date aren’t directly comparable to after.
• SEO tools will be disrupted. Rank trackers like SEMrush and Ahrefs relied on &num=100. Expect some reporting quirks or rising costs as they adapt.
• Clicks matter most. Your traffic didn’t change. If you’re getting found, you’re still getting found.
• CTR looks better. Because junk impressions are gone, your click-through rate is now a truer measure of performance.

What Businesses Should Do After the Impressions Drop in Google Search Console

Here’s the same advice I gave my clients:

• Don’t change your strategy. If you were ranking before, you’re still ranking. Focus on clicks, conversions, and leads.
• Mark September 10 in your reporting. Treat it like a line in the sand. Don’t panic when stakeholders see lower impression counts.
• Educate your team. Share this update with anyone who reviews your SEO reports so they understand the context.
• Keep doing what works. Quality content, optimized sites, and active Google Business Profiles still drive results.

Final Thoughts on the Google Search Console Impressions Drop

While the sound of a Google Search Console impressions drop sounds like a bad thing, it's actually on the contract.

For years, impression data was inflated by bots scraping search results.

Now your reporting reflects reality: real humans, real searches, real clicks.

If you’re staring at dropping impressions and wondering if your SEO is broken, take a deep breath.

**It’s not. The game hasn’t changed. **

Google just cleaned the scoreboard.
