Google’s March 2024 Search changes targeted scaled content made to manipulate rankings without adding value—not AI-generated writing as a category. The announcement covered scaled content abuse, site reputation abuse and expired domain abuse. Google later said the rollout was complete and reported a larger reduction in low-quality, unoriginal results than it had initially forecast.
What Google changed in March 2024
On March 5, 2024, Google announced improvements to its ranking systems and changes to its spam policies. The changes addressed three practices: scaled content abuse, site reputation abuse and expired domain abuse. The “AI-generated slime” framing in the March 6 Futurism headline is not Google’s name for a policy or a technical category.
For scaled content abuse, Google said it would focus on the behavior of producing content at scale to boost search rankings, whether automation, people or both were involved. The policy’s concern is manipulative production that fails to provide value—not simply the use of AI.
Does Google penalize AI-generated content?
Not simply because it was made with AI. Google’s policy describes abusive scaled content, and its current examples include using generative AI to create many pages without adding value for users. The same policy also covers low-value content produced by other means, including scraping and transforming material or combining pages without meaningful additions. Google’s spam policies say violations may lead to lower rankings or removal from Search results.

What counts as scaled content abuse?
Google’s current policy page gives examples of scaled content abuse. They include:
- Using generative AI to create many pages without adding value for users.
- Scraping and transforming other material without adding value.
- Combining content from different pages without meaningful additions.
- Creating multiple sites to conceal the scale of content production.
- Producing incoherent pages stuffed with search terms.
The examples illustrate that “scaled” refers to a production pattern used to manipulate Search, not just a high publishing volume. Google’s March announcement put it this way: “we’re strengthening our policy to focus on this abusive behavior — producing content at scale to boost search ranking — whether automation, humans or a combination are involved.” The current policy definition also covers attempts to manipulate generative AI responses within Google Search.
What did Google’s 40% and 45% figures mean?
Google’s March announcement initially projected that its ranking-system work, together with previous efforts, would reduce low-quality, unoriginal content in Search results by 40%. In an April 26, 2024 update, Google said the rollout had finished on April 19 and reported 45% less such content than before the work.

These are two different Google figures: 40% was the expected collective reduction; 45% was Google’s later reported result after rollout. Neither figure is an independently audited measure, and neither measures AI-generated content specifically.

The March 2024 announcement and the September 2026 update are separate Search events. The later update is a named spam-update incident on Google’s Search Status Dashboard, not a new name for the 2024 policy changes.
Rank #4
| Detail | March 2024 announcement | September 2026 spam update |
|---|---|---|
| Date and type | Google announced ranking-system improvements and spam-policy changes on March 5, 2024. | Google’s dashboard says the spam update began September 24, 2026 at 09:15 PDT. |
| Stated scope | Policy changes addressed scaled content abuse, site reputation abuse and expired domain abuse. | Google lists the update as global and applying to all languages. |
| Stated target | Google described specific policy areas, including scaled content produced to boost rankings without value. | The public dashboard entry does not name a specific spam tactic or say that AI-generated content is the target. |
| Status and timing | Google said the rollout completed on April 19, 2024. | Google says the rollout may take up to two weeks to complete. |
The September 2026 dashboard entry establishes the update’s scope and estimated rollout window, but it does not identify what kind of spam it targets or establish its effect on any particular site. It should not be treated as evidence that Google is now targeting AI-written pages as a class.
