AWhat happened?
One of the biggest changes in this period. Google folded its separate “helpful content” system into its core ranking systems and said it expected to cut low-quality, unoriginal content in results substantially.
From this update on, “helpful content” is part of core ranking, so this atlas shows no separate helpful content updates after September 2023.
BWhat did Google change?
A more complex core update involving changes to multiple core systems. The helpful content system was incorporated into core ranking, so there are no more separately announced helpful content updates. Google said it expected a 40% reduction in low-quality, unoriginal content in results, and later reported a 45% reduction.
Google’s announcement, summarised: Google released the March 2024 core update; the rollout may take up to a month. Completion was confirmed as of 19 April 2024.
CWho could be affected?
Documented by Google
- Search results broadly, with a stated focus on reducing unhelpful, unoriginal content.
Our inference — not confirmed by Google
- Sites previously hit by helpful content updates, and sites with large volumes of search-first content, were the most likely to see movement.
Being in a category above doesn’t mean a site was penalised; many sites in every category see no change.
DWhat should website owners do?
- 1Compare Search Console performance for the weeks before the update with the weeks after it finished, not during the rollout.
- 2Find which landing pages and queries changed most, rather than looking at the site total.
- 3Read those pages as a visitor would: are they original, complete, current and clearly better than what else ranks?
- 4Rule out technical causes first: indexing, redirects, canonicals, server errors, tracking changes.
- 5Improve content where it genuinely falls short; Google says changes can take months to be reflected.
