What is Google Algorithm Update?
A Google algorithm update is a change to the ranking system that reshapes SERPs across large swathes of the web. Google runs thousands of changes per year; only a few are "core updates" — broad, named, multi-week rollouts that shift 5-30% of rankings across most niches.
How Google Algorithm Update works
- Named update types: Core (broad quality reassessment), Helpful Content (content-quality signal), Spam (link + content spam crackdowns), Product Reviews (review-page quality).
- Rollouts take 1-3 weeks — do NOT panic-optimise on day 3. Wait for the update to finish before diagnosing losses.
- Recovery from a hit usually takes the NEXT core update — not fixable in days.
- Track update dates against your traffic — GSC + Search Engine Land + Google's official Search Status Dashboard.
- AI Overview + March 2024 Helpful Content update reshaped rankings more than any update since Panda 2011.
Example
The August 2024 core update rewarded sites with strong topical authority + first-hand experience and penalised thin AI-generated content, aggregator sites, and low-quality affiliate roundups. Recovery required a fundamental content-quality rebuild, not tag tweaks.

How do I know if I was hit by a Google algorithm update?
Cross-reference your traffic drop date with Google's Search Status Dashboard + Search Engine Land's update timeline. Losses on the exact rollout start date = algorithm impact.
How long does it take to recover from a Google update?
Typically the NEXT core update (6-12 weeks later) is the earliest recovery window. Some sites recover in mid-cycle sub-updates. Panic-tweaking rarely accelerates recovery.
What are Google's Core Web Vitals updates?
Page-experience updates that made Core Web Vitals a ranking signal, initially rolled out May-June 2021 with incremental refinements since. Impact on rankings is minor compared to content-quality updates.

Core Web Vitals
Core Web Vitals are Google's three page-experience metrics: LCP (loading), INP (interactivity — replaced FID in 2024), and CLS (visual stability). They're a confirmed Google ranking factor, though a small one — a tiebreaker between otherwise-equal pages more than a primary lever.
SERP Volatility
SERP volatility is a measure of how much Google's rankings are shifting across a keyword set on a given day. High volatility = many pages moving up or down = likely algorithm update or index refresh. Low volatility = stable SERPs. It's the single best real-time indicator of Google-side changes.
