TL;DR Summary:
Volatility Without Confirmation: Three ranking turbulence spikes hit within a week, but Google confirmed no algorithm update, so treat sudden changes as noise for now.Num=100 May Return: Google could restore the 100-results-per-page setting, potentially disrupting rank-tracking data and making historical comparisons unreliable.AI Shrinks Clicks: AI Overviews and AI Mode reportedly deliver about 0.9% click-through rates, while even opting out may reduce visibility in traditional results.Search Still Growing: Alphabet’s search revenue increased despite AI pressure, while Bing introduced separate controls for AI training and real-time content grounding.Google num=100 Parameter Signal Returns Amid Volatility Risk | Week of November 1 2026
No Google algorithm update was confirmed this week. Google’s own update dashboard did not report a live rollout even as rank-tracking tools and SEO forums flagged a third unconfirmed volatility spike in just over a week. The most concrete development instead involves tooling: Google may restore the num=100 parameter, the setting that let users and tools view 100 search results per page before Google removed it in September 2025.
Unconfirmed Volatility Spikes, Three Times in a Week
Barry Schwartz reported a new ranking volatility spike on October 27, writing that turbulence began roughly 12 hours before his report. This followed chatter on October 20–21 and an earlier unconfirmed update on October 24. That’s three separate volatility signals in about a week, and Google’s dashboard has not confirmed any of them as a live update. In practice, this means site owners seeing ranking swings right now have no official explanation to point to — only forum pattern-matching and tool data. Treat any single week’s ranking changes as noise until Google confirms otherwise, per Search Engine Roundtable.
The num=100 Parameter May Return
Google is reportedly considering restoring the num=100 parameter, which let users and rank-tracking tools pull 100 results per page instead of the default 10. Google dropped this option in September 2025 as part of an anti-scraping effort, and the removal scrambled impression and average-position data across many SEO tools overnight. If the num=100 parameter comes back, expect a second disruption: historical data before and after the original removal, and now potentially after a restoration, won’t line up cleanly. Anyone comparing year-over-year Search Console trends should flag this as a known data gap, not a real ranking change.
Search Console Link Reports Still Incomplete
Google reiterated this week that the Search Console link report does not show all links pointing to a site, including spammy ones, and that the report only ever showed a sampling. Google also confirmed the report can include disavowed links. This came alongside continued complaints from site owners that link counts have dropped compared to earlier periods. The practical takeaway: don’t use Search Console’s link report as a complete backlink audit. It was never designed to be one, and Google says that hasn’t changed.
Alphabet Q3 Earnings Show Search Growing, Despite AI Pressure
Alphabet’s Q3 2026 earnings showed total company revenue up 25% to $127.6 billion. Search-specific numbers varied slightly by source: one report put search revenue at roughly $82 billion, up from $74 billion a year earlier, while another figure cited search advertising growth of 12% to $63.35 billion, with YouTube ads up 9% to $11.21 billion. Some coverage noted both figures fell short of analyst expectations amid growing scrutiny of AI’s effect on Google’s ad business. For publishers, the headline is that search ad spending is still rising in absolute terms, even as AI Overviews changes how people click through to sites.
AI Overviews Click-Through Rate Sits Near 0.9%
A new study cited in Search Engine Roundtable’s October 29–30 recaps found AI Overviews and AI Mode produce roughly a 0.9% click-through rate on the links they surface. The same reporting found that opting out of AI inclusion doesn’t protect click volume — it still leads to a drop in clicks on regular web results. Google also rolled out query refinement bubbles inside AI Overviews and is testing sponsored and organic product blending in AI Mode. For site owners, this confirms that AI features are suppressing click-through broadly, whether or not you choose to participate in them.
Bing Adds Separate Controls for AI Training vs. AI Grounding
Microsoft announced new Bing controls letting site owners choose separately whether their content can be used for AI training, AI grounding (real-time retrieval for AI answers), or both. This gives publishers a level of control Google doesn’t currently offer in the same form — right now, opting out of Google’s AI Overviews affects broader search visibility too, per the 0.9% CTR findings above. Bing’s split-control approach may become a reference point if Google faces pressure to offer similar granularity.
What to do this week
Check your Search Console performance report for October 20–31 and note any unexplained ranking swings — do not act on them yet, since Google’s dashboard has not confirmed an update as of this week’s reporting. If you want a second opinion beyond raw Search Console numbers, a tool like Labrika can cross-check your indexed-versus-crawled pages and flag technical issues that might explain swings unrelated to any algorithm update.
If you use a rank tracker that reports average position or impressions, check whether it sources data via the num=100 parameter, and flag any sudden shifts in those metrics as a possible tooling artifact rather than a real ranking change.
Go into Search Console’s Links report and compare your current total linking sites count against a screenshot or export from three months ago — if the number dropped, check Google’s own clarification before assuming lost backlinks are the cause.
If you publish content you don’t want used for AI training, check Bing Webmaster Tools for the new AI training and AI grounding toggles and set them explicitly rather than leaving defaults in place.
