Quick answer: At its Search Central Live Deep Dive event in Barcelona, Google explained why 2026 has brought more frequent spam updates. The short version: there is far more new content than before, Google is now using AI to find more spam, and scaled content has overtaken link spam as the bigger problem. Google’s Gary Illyes added that Google filters out 40 billion spam pages a day.
What happened
The comments came from Google Search Central Live Deep Dive Europe 2026 in Barcelona and were summarized in a recap by attendee John Campbell, then reported by Search Engine Roundtable on October 5, 2026. Google addressed a question many SEOs have been asking all year: why are there so many spam updates?
Google’s answer centered on volume. There is “so much more new content than before,” and much of it is low-effort, AI-generated material often called “AI slop.” To keep up, Google is deploying AI-based systems to detect spam at a scale its older classifiers could not.
Three reasons Google keeps updating its quality systems
- More formats: Search now includes far more than ten blue links, and each format needs its own quality standards.
- More breadth: Core updates increasingly work at the page level rather than the domain level, which is why individual pages on the same site can move in different directions.
- Content problems: Cloaking, doorway pages, scraped content, link spam and hacked sites remain issues, but Google said scaled content is now a bigger problem than link spam.
Why it matters
This is one of the clearest statements yet that mass-produced AI content is the main target of Google’s spam work in 2026. It also explains the timing: the September 2026 spam update is rolling out in multiple waves just as Google updated its guidance to say it is “critical” to manually fact-check AI-generated content. Sites publishing large volumes of unreviewed AI pages face rising risk with every update.
Key facts
- Event: Google Search Central Live Deep Dive Europe 2026, Barcelona
- Spam filtered: 40 billion spam pages per day (per Gary Illyes)
- New approach: AI-powered spam detection
- Biggest issue: Scaled content, now ahead of link spam
- Outlook: More spam thresholds and updates are expected
What to do now
- Review any programmatic or AI-assisted content for real added value, not just keyword coverage.
- Consolidate or remove near-duplicate pages created to target small keyword variations.
- Add human review, original data and first-hand experience to content that matters.
FAQ
Does Google penalize all AI content?
No. Google’s position is that content made primarily to manipulate rankings is the problem, regardless of how it was produced. But low-effort AI content produced at scale is exactly what its new systems are built to catch.
What is scaled content abuse?
It is the practice of generating many pages, by AI, people or automation, mainly to rank in search rather than to help users.
