Helpful Content Update
In one line
The Helpful Content Update (HCU) is Google's algorithm move to reward content built for people and demote thin pages built primarily for search engines.
Going deeper
The Helpful Content Update was introduced in 2022 and went through several iterations before being folded into Google's broader Core Update machinery in 2024. The core idea is simple: separate content made for people from content made primarily to rank.
Its direct target was thin, SEO-driven mass content — keyword-stuffed pages with little real value, lightly rewritten copy from other sites, and the wave of automatically generated AI slop now flooding the web.
For GEO, HCU is one of those updates that pulls SEO and GEO in the same direction. LLMs prefer first-hand, citation-safe sources, so the kind of page that survives HCU is the same kind of page that tends to get quoted in AI answers.
