Num=100 and filter=0 gone

[Rlilly]

these 2 URL parameters no longer work in Google Search, Num=100 and filter=0

I used it extensively to check page power, how many results for a keyword pages from a site would come up in the first 100, and track competitor pages.

If anyone has suggestions how to get 100 results per page and using the filter, please let me know

Let’s hope it’s a bug, not intentional, and gets fixed:

Been gone for awhile for me. Only num=50 would work. You could use num=anything and it would default to either 10 or 50 if it were over 50.

Such a stupid change by Google that's done nothing but break so many rank trackers. Hoping it's a bug and they revert ASAP.

g ain't that stupid. It's NOT a bug. Kiss it goodbye because it revealed TOO much regarding biz and the web.

EVERY REPORTING TOOL that g allowed in the past has been NEUTERED or REMOVED. Expect more of the same, not less.

Google has finally commented on the removal of the &num=100 parameter, and the reply is as vague as expected:

“The use of this URL parameter is not something that we formally support.” – Google spokesperson

That’s it. No explanation for the strange GSC data we’ve been seeing.

Key Takeaways

•GSC Data Anomalies: Impressions and average position data remain skewed. In some cases, impressions dropped by nearly 47%.

•Rank Tracker Impact: Most tools are settling on tracking the top 20 results. But for diagnosing issues, the top 100 view is still valuable.

•Average Position Credibility: With &num=100 disabled, average position in GSC (especially desktop) may now be more reliable.

•Anti-Scraping Signal: Google even advertised an “anti-scraper” role recently; don’t expect a rollback.

What To Do?

•Annotate GSC reports for 10 Sept 2025 to account for the sudden change.

•Expect artificial impressions from rank trackers to creep back up over time, even as average position stabilises.

This quiet change has far-reaching consequences for rank tracking and client reporting; even if Google’s explanation is little more than a shrug.
