Helpful content system and updates

A Google system launched in August 2022 to demote sites with a high proportion of content made for search engines, integrated into core ranking with the March 2024 core update.

In full

The system originally applied a site-wide classifier that could weigh on an entire domain, and it ran as discrete updates with long recovery cycles — the September 2023 update was particularly severe for many publishers. With the March 2024 core update Google folded the signals into its core ranking systems, so 'helpfulness' is now assessed continuously and there are no separate HCU announcements. The self-assessment questions in Google's creating helpful content documentation remain the reference standard.

Example

A recipe blog hit in 2023 rebuilt its content and saw partial recovery only at a subsequent core update, not in between.
