Resoneo Publishes List of 120 Google Twiddlers That Re-Rank Search

Google runs at least 120 twiddlers — adjustable re-ranking systems that reshape search results after the main ranking pass — according to a list published on November 2, 2026 by Olivier de Segonzac of French agency Resoneo. Of those 120 names, 111 are exclusive to this list, meaning they had not appeared in earlier public documentation of Google's systems.

What is a twiddler, in plain terms?

A twiddler is a rule. It sits between Google's core ranking and the results you see. Core ranking decides roughly which pages deserve a spot. Twiddlers then boost, demote or rework that ordering based on dynamic criteria, signals and business rules. Think NavBoost, user engagement, freshness, or manual and algorithmic filters. A page can rank fifth on raw relevance and still disappear because a spam demotion or freshness signal pushed it down.

That layering matters for anyone doing SEO. You're not optimizing for one algorithm. You're optimizing for a base rank that then passes through dozens of adjustment layers.

Takeaway: twiddlers are the fine-print of Google ranking, and most of them were invisible until now.

Where did the names come from?

This isn't the first glimpse. Names like NavBoost and related systems surfaced during the Google documents leak in the DOJ antitrust proceedings. Resoneo built on that foundation. De Segonzac announced the catalog on X: "We found Google's list of twiddlers, the programs that rework search results after ranking: 120 of them! 111 names are exclusive, among them AI Mode's fan-out plan, a filter still named after Bard or an Expertise twiddler."

That quote carries the two most interesting data points. First, the count: 120 systems. Second, the exclusivity: 111 names are new to the public record. That's 93 percent of the list appearing for the first time.

The internal dating is telling, too. One filter still carries the name "Bard" — Google renamed the product Gemini long ago, but the internal plumbing kept the old label. That gap between public branding and internal machinery is a useful reminder that published product names rarely match what's under the hood.

How did Resonea organize the 120 systems?

The list breaks into seven functional categories:

• Web results: quality, authority, trust — systems like Expertise, Topic authority, Domain classification, Web health and "Natural Pearls"
• AI and rankers — RankBrain, the "Search plan (fan-out)" behind AI Mode, a "Relevance oracle," the Bard filter and a "For loop ranker"
• Spam, removals and safety — spam demotions, DMCA site penalties, crime demotion, SafeSearch variants, a revenge porn filter and kid-friendly search
• Freshness, repeat queries and preferences — date score, "Freshest on repeat queries," domain preference and personalization boosts
• SERP layout and verticals — dynamic SERP, web clusters, forums, hashtags, shopping clusters and "About this result"
• Images and Lens — image aesthetics, commercial images, Lens sensitivity filters and multimodal systems
• Video and YouTube — clickbait demotion, Shorts authenticity, channel diversity, playback speed and video engagement signals

Some names are self-explanatory. "YouTube clickbait" and "Short duration demotion" do what they say. Others are cryptic. "Starbow," "Toledo," "Beehive," "Aquila," "CatNorvi" and "RWJ" give no hint of function — likely internal codenames that will fuel speculation in SEO forums.

What should site owners watch?

The confirmed part: the list exists, it names 120 systems, and it aligns with what the DOJ leaks established about Google's layered re-ranking architecture. The speculative part: what each unnamed twiddler actually does. Resoneo published the names; the mechanics behind codenames like Toledo or Beehive remain inference, not documentation.

Vertical-specific twiddlers matter most for publishers in those lanes. Video sites face roughly a quarter of the list — YouTube deduplication, Shorts ranking, YouTube shopping, localization and demographics. E-commerce content passes through shopping personalization, deals, specialty merchants and shopping cluster annotators. Image-heavy sites deal with aesthetic scoring, commercial image boosts and "inspiration diversity."

AI Mode's presence in the list is the forward signal. A "Search plan (fan-out)" twiddler confirms re-ranking logic extends into Google's AI answers, not just the ten blue links.

Watch whether Google responds, and whether future testimony or leaks fills in the 111 blanks.
