Google announced the May 2026 core update on Thursday afternoon, and the SEO community quickly felt its effects over the weekend. Many webmasters and digital marketers reported noticing significant changes in their site rankings starting late Friday, continuing into Saturday and Sunday. While some signs of the update’s initial impact seemed to ease today, Monday, experts anticipate increased activity as the rollout progresses over the next couple of weeks.
The update was officially launched around 11:43 am Eastern Time, with Google indicating that the entire process could take up to two weeks to complete. Early observations suggest widespread volatility across various websites and niches.
Social media chatter and online forums are abuzz with reports of algorithmic shifts. Some SEOs observed sharp traffic declines, with one user attributing a 50% drop to the update, while others experienced unexpected surges or stability. Several site owners noted that their traffic dropped dramatically, with some seeing losses of 80-100%, reflecting a significant shake-up in search rankings. Conversely, a few sites, even with questionable content strategies, have experienced spikes in visitors or have remained unaffected.
In regions like Brazil, smaller sites still present on Google Discover have been removed, leaving only major news portals or sites with high backlink counts visible in search results—even those featuring superficial or clickbait content. Meanwhile, in Europe, the impact appears to be more stable so far, but this could change as the update continues.
Many site owners express concerns about the unpredictability of recent Google updates. Historically, recovery from algorithm shifts was possible; however, since 2022-2023, the situation has worsened. The pattern now exhibits a downward trend that seems increasingly irreversible, with site traffic diminishing exponentially over time. A number of SEOs have reported an overall decline of around 80% compared to pre-update levels, with some seeing near-total traffic loss.
Tracking tools indicate heightened volatility over the weekend. Platforms such as Semrush, Advanced Web Rankings, SimilarWeb, Zutrix, Wincher, SERPstat, Sistrix, and others have all shown spikes in fluctuations, confirming the unpredictable nature of this update. Notably, data visualization tools that aggregate multiple metrics display a clear increase in search volatility, reinforcing the perception that Google’s recent changes are particularly impactful.
Many SEOs and digital marketers share their observations publicly, noting that while some websites remain relatively stable, others have experienced dramatic ranking shifts. The broad consensus is that this update feels particularly aggressive and substantial, with a strong “teeth” and enforcement emphasis noticeable across various industries and regions.
Additional insights from industry analysts highlight the unpredictability of modern Google updates. Some report partial recoveries, but overall, the trend remains heavily downward for many sites. The recent volatility underscores the importance of staying adaptable and closely monitoring performance metrics as the update continues to unfold.
