Helpful Content Update (HCU)
The Helpful Content Update is a series of Google algorithm updates starting August 2022 that prioritize "human, people-first" content and demote thin, search-engine-first material.
Helpful Content Update — explained in more detail
The HCU launched as a standalone site-wide classifier update. Sites whose content Google classifies as “search-engine-first” (produced for rankings, not for readers) receive a sitewide penalty — even strong individual articles drop while the classifier signal is active. As of March 2024, the HCU classifier was rolled into the core ranking stack; standalone HCU rollouts are no longer announced, and the logic now runs with every core update.
Typical triggers: mass affiliate content without first-hand experience, AI text without human editing, generic “What is X?” pages adding no value over existing results, off-topic site expansion (“page sprawl”).
Example / In practice
A hobby site about coffee machines publishes 200 additional articles in 2023 on insurance and loans — generic affiliate content. With the September 2023 HCU, the entire domain loses roughly 70 % organic traffic, even on its core coffee topics. Fix: remove or split off the off-topic content.
Distinction from similar terms
Core update is the broad algorithm refresh; the HCU was initially separate and is now part of it. Spam update targets manipulative techniques (cloaking, link spam) — HCU targets content quality and writing intent. E-E-A-T is the evaluation grid given especially high weight during HCU.
