March 2024 core update – bigger than before

Google started to roll out its first core update of the year and its first algorithm update of the year – the March 2024 core update. Elizabeth Tucker, Director of Product, Search at Google, told Search Engine Land that the update will help reduce unhelpful content in Google Search by 40%. “We expect that the combination of this update and our previous efforts will collectively reduce low-quality, unoriginal content in search results by 40%,” Elizabeth Tucker wrote.

November 2023 Core and Review System Enhancements, Plus Course Discovery Innovations In November 2023, Google rolled out its fourth Core Update of the year, following its initial launch in March. This update was accompanied by another significant revision to the Review System, similar to what was seen in October. The primary focus of these updates is to refine the search experience. Key features include improved recognition of frequently visited websites, a multifaceted search filter for diverse viewpoints, and the introduction of “Notes,” an experimental feature from Google’s Search Labs.

Significantly, on November 15, 2023, Google announced an update that considerably boosts the online visibility of educational courses. By utilizing structured data, this update offers an enriched presentation of course details, such as price and duration, through a carousel display in Google Search results. This enhancement simplifies the process for users to locate and compare educational offerings, in line with Google’s ongoing efforts to enhance user experience. The update is especially noteworthy for its potential influence on how prospective students discover and evaluate educational opportunities.

October 2023: Dual Updates to Spam Detection and Core Algorithm Google’s October rollout featured two main updates: an enhancement to its spam detection capabilities and a significant change to its Core Algorithm. The spam update expands the system’s capacity to identify various languages and types of spam. Meanwhile, the Core Algorithm update influences search rankings and user experience, aiming to elevate search quality and decrease spammy content in search results.

Introduction of the Helpful Content System in September 2023 September 2023 saw the debut of Google’s Helpful Content System, a crucial update to its ranking algorithm. This system is designed to evaluate the relevance and value of web content more effectively. It marks a substantial shift in content strategy requirements, emphasizing the need for content that prioritizes user satisfaction and quality.

Broad Core Update of March 2023 Google initiated its first broad core update of the year on March 15, 2023, with completion 13 days later. This update was a continuation of Google’s commitment to promoting high-quality content. SEO analysts noted that the March update had more pronounced effects compared to the previous September update, with significant fluctuations in keyword rankings and SERP positions. This update warrants a close examination of analytics for any long-term content strategy adjustments.

February 2023 Product Reviews Update On February 21, 2023, Google announced an update to its product review system, expected to be fully implemented within two weeks. Building on its previous English-focused updates, this enhancement aimed to elevate the system’s utility on a global scale, promoting high-quality reviews in multiple languages including Spanish, German, French, Italian, Vietnamese, Indonesian, Russian, Dutch, Portuguese, Polish, and English. This marked the first update to the Product Reviews system since September 2022 and its sixth iteration overall.

Oct. 20, 2022

Google released the October 2022 spam upgrade on October 19–21, 2022. They provided a link to a document outlining SpamBrain, their AI spam filtering program. Spam Brain is adept at combating “behaviors that aim to narrowly escape breaching [their] quality requirements, but are still manipulative in nature,” according to the authors. One of the instances mentioned is being able to tell whether product reviews are actually hands-on evaluations or just updated product descriptions. Numerous sites were severely damaged by this upgrade. As of November 7, I believe that this modification was caused by SpamBrain being more adept at recognizing content that violates Google’s quality standards. This filter might be removed by disavowing. Read more here.
October 18, 2022 – There was no officially declared update, but several of the sites we watch saw enormous gains, and we have heard rumors of sites suffering significant losses. Some claim that Google’s index has far fewer pages now. It’s possible that Google changed the way it indexes information. Or perhaps Google’s helpful content classifier is at work here.

    The November 16th 2021 Confrimed

    Core Update is now rolling out live. As is typical with these updates, it will typically take about one to two weeks to fully roll out.

    July 2021 Core Update — July 1, 2021


    A follow-up to the June Core Update, the July 2021 Core Update rolled out from July 1-12. Peak volatility on MozCast hit 102.7°F on July 1st, but we saw temperatures in the 90s on July 5th, 8th, and 11th. Like most Core Updates, Google was light on specifics.

    Rank tracking tools and webmaster chatter suggested a significant update, with MozCast measuring 101°F, but no update was confirmed by Google. Some industry analysts suggested the changes were rolled back the next day and may have been temporary.

    Google Glitch — August 10, 2020

    ConfirmedSEOs reported massive ranking changes for a few hours on August 10, which then seemed to disappear. Google later confirmed a glitch in their indexing systems. MozCast registered 97°F the following day (August 11), but it’s unclear if this event was related.

    Google Bug Fix — June 22, 2020

    UnconfirmedRank-tracking tools showed heavy flux, with MozCast reaching 96°F. While no algorithm update was confirmed, a Google rep confirmed an indexing bug affecting Disqus comments that would be fixed during this time period.

    May 2020 Core Update — May 4, 2020

    ConfirmedGoogle announced another Core Update (the second of 2020), which caused heavy rankings flux from about May 4-6. Peaking at 113°, it measured on MozCast as the second-highest Core Update after the August 2018 “Medic” update.

    COVID-19 Pandemic — March 11, 2020

    UnconfirmedWhile not an algorithm update, per se, COVID-19 dramatically shifted consumer search behavior. The WHO pandemic declaration on March 11th seemed to be a pivotal turning point. In March on MozCast, 16 out of 31 days topped 90°F, and rankings were in high flux well into April and May.

    2019 Updates

    Site Diversity Update — June 6, 2019

    ConfirmedGoogle pre-announced a “site diversity” update, claiming it would improve situations where sites had more than two organic listings. Moz data showed that, while the update did marginally improve SERPs with 3-5 duplicate sites on page one, the impact was relatively small.

    June 2019 Core Update — June 3, 2019

    ConfirmedGoogle pre-announced a “core” update, but with limited details. Sites impacted in previous core updates seem to have been affected, in some cases, and some major UK publishers reported heavy losses. On average, the impact was smaller than the August “Medic” update, as measured by MozCast.

    Indexing Bugs — May 23, 2019

    ConfirmedTwo days in a row, Google confirmed indexing bugs. The first bug reportedly was preventing new content from being properly indexed. MozCast confirmed unusually high SERP flux from May 23-25 (peaking on the 23rd), but it’s unclear if this was directly related to the bugs.

    Deindexing Bug — April 5, 2019

    ConfirmedGoogle confirmed a bug that dropped pages from the search index around the weekend of April 5th. Moz data suggested drops on April 5th and 7th, with about 4% of stable URLs falling off of page one. Most sites recovered soon after.

    March 2019 Core Update — March 12, 2019

    ConfirmedGoogle confirmed a “core” update, stating it was the third major core update since they began using that label. MozCast hit a peak of 101.2°F, a bit below March 1st temperatures. No specific details were given about the nature of the update.

    19-result SERPs — March 1, 2019

    UnconfirmedFor one day, Google showed anomalous page-1 counts, with up to 19 organic results. These appeared to be related to In-depth Articles, which disappeared entirely on March 6. MozCast reached 108.2°F, but it’s unclear how much of this was due to the temporary boost in organic counts.

    Unnamed Update — February 6, 2019

    UnconfirmedAfter a relatively quiet December and January, tracking tools detected heavy ranking flux, with MozCast reaching 103.4°F.
