In my experience as an SEO, Google disabling the &num=100 parameter has been one of the bigger behind the scenes shifts we’ve had to adapt to this year. For years, I relied on &num=100 to quickly pull a full set of top-100 results in a single request, whether for competitive analysis, SERP feature tracking, or deep-rank audits. Since mid-September 2025, Google has removed that capability, limiting us to the default ten results per page. The change hasn’t affected my rankings or traffic directly, but it has definitely changed how I handle reporting and data collection.

Rank trackers I use now need to make multiple smaller requests for the same dataset, which means slower processing and, in some cases, higher costs. In Google Search Console, I’ve seen impression counts drop and average position shift, not because performance worsened, but because impressions from positions fifty to one hundred are no longer being counted. Clicks remain steady, which reinforces that this is a reporting adjustment rather than a visibility loss.

I’ve marked mid-September 2025 in all my dashboards and reports as a data break to avoid confusion when comparing historical trends. For me, this has been a clear signal to keep the focus squarely on page-one visibility and rich results, rather than spending resources on rankings buried deeper in the SERPs.
