Reviews of the change started round September 10, and rapidly unfold by means of the website positioning neighborhood as rank-tracking instruments confirmed disruptions.
Google hasn’t but issued a public assertion.
What’s Occurring

Over the weekend, practitioners observed that forcing 100 outcomes typically not works, and in earlier checks it labored solely intermittently, which steered a rollout or experiment.

Google has seemingly eliminated the power to do &num=100, can anybody affirm?
In the event you use the parameter, solely 2 pages present. This “2 pages” filter has been examined for a yr, however often in the event you clicked to web page 2 they’ve the remainder the highest 100. Now it exhibits nothing after web page 2.

Ripple Results On Rank-Monitoring Instruments
Clark and others documented instruments displaying lacking rankings or error states because the change landed.
Some platforms’ search engine outcomes web page (SERP) screenshots and each day sensors briefly stalled or displayed information gaps.
A number of website positioning professionals noticed sharp declines in desktop impressions in Google Search Console beginning September 10, with common place rising accordingly.
Clark’s evaluation connects the timing of these drops to the &num=100 change. He proposes that earlier desktop impression spikes have been partly inflated by bots from website positioning and AI analytics instruments loading pages with 100 outcomes, which might register many extra impressions than a standard 10-result web page.
This can be a neighborhood idea at this stage, not a confirmed Google rationalization.
Re-Analyzing “The Nice Decoupling”
Over the previous yr, many groups reported rising impressions with out matching clicks and related that sample with AI Overviews.
Clark argues the &num=100 change, and the ensuing software disruptions, provide an alternate rationalization for not less than a part of that decoupling, particularly on desktop the place most rank monitoring occurs.
This stays an interpretation till Google feedback or gives new reporting filters.

Ryan Jones suggests:
“The entire AI instruments scraping Google are going to consequence within the shutdown of most website positioning instruments.

Wanting Forward

Device distributors are already adapting, and the neighborhood is reevaluating how a lot of the ‘nice decoupling’ story stemmed from methodology relatively than consumer habits.
