So far, 2024 has seen 4 updates that have shaken up the SERPs in a big way.
Google December 2024 Core Update
December 11 marked the start of the Google December 2024 core update. Following closely after the November update, the December installment targeted different core systems.

Google November 2024 Core Update
The November 2024 Google Core Update was announced on November 11 and was estimated to take around 2 weeks to roll out. It highlighted Google’s ongoing commitment to making its search results as useful as possible for users. It cracked down further on websites that publish only SEO-driven content and sought to reward those with quality, user-first content.
—
Google August 2024 Core Update
Google announced its August Core Update on August 15, 2024, and it was completed on September 3, 2024, after 19 days. It marked a commitment to improving search results for users by cracking down on SEO-driven content with little user relevance and further promoting quality user-first content. This update also took on board feedback the search engine giant received from its September 2023 helpful content update, which meant many smaller, independent websites had a drop in rankings.
—
Google March 2024 Core Update
This core update started rolling out on March 5, 2024, and it took a huge 45 days to complete. One of the biggest updates in years, it aimed to improve user experience and crack down on unoriginal, low-quality content that has only been created with manipulating search results in mind. Instead, by refining its core ranking system, the update means that Google now puts original, helpful content that satisfies user intent first. Affecting all types of content across all regions that the search engine operates in, the update means that those who produce content that is human first and useful will be rewarded when it comes to search rankings. This change to Google spam policies has already had a big impact, with the amount of unoriginal content appearing in results being down a massive 45%, which can only be a good thing for enhancing user experience.

Google March 2024 Spam Update
March 5 was a big day for rolling out Google updates, with the search engine’s spam update starting on the same day. This one didn’t take quite so long to complete – just 14 days –
finishing on March 20, 2024. Google spam policies, like its previous link spam updates, have been around for a long time to make sure that poor quality, spammy content and links do not appear in search results. Google accepts AI-generated content that provides real value to the user. However, it’s thought that this update targets such content that is mass-produced on a big scale with the sole goal of climbing the SERPs in mind.
The update focused on 3 main areas:
· Expired domain abuse
· Scaled content abuse
· Site reputation abuse
To avoid falling foul of this update with negative search ranking movement, making content improvements that ensure the user is put first is the way to go.

—
November 2023 Core Update
November 2, 2023, saw the start of the Google November 2023 core update, and just under 26 days later, it was confirmed as complete. At the time, it was the longest core update rollout and the fact that it overlapped with the November 2023 reviews update and huge shopping days like Black Friday and Cyber Monday, it was seen as being pretty major. The broad core update affected all types of content in all regions and languages and promoted good webpages. With the overlapping updates, there was a lot of SERP volatility in the early stages. Ultimately, the update built on previous updates, refining how the search engine assesses content and promoting valuable content over low quality stuff.
—
October 2023 Core Update
The Google October 2023 core update came just a few weeks before the November one on October 5 and took 13 days and 23 hours to finish rolling out. It was a global update that focused on emphasising top-quality content in the SERPs to demote low-quality websites and promote those that produce trustworthy and helpful content. This core update had an impact on SERP features, including featured snippets and Google Discover. Any SEO strategy post-core update needs to take into account core update best practices, making helpful content a priority and focusing on user experience.
—
October 2023 Spam Update
At the same time as the October core update, on October 4, 2023, the Google October 2023 spam update started its rollout, ending 15 days later on October 20. This was a penalty update that targeted all languages and regions, including Vietnamese, Turkish, Chinese, Indonesian, and Hindi languages.

· Hacked content– Content that is published on a site without the owner’s permission due to security flaws. This type of content could also install malware or malicious content on devices used to access such content.
· Cloaking– Content that intends to mislead users and manipulate rankings.

September 2023 Helpful Content Update
The month before saw the September 2023 Google helpful content update come into force – starting on September 14 and spanning 13 days and 11 hours. This was a big update from Google as SEO-first content was impacted. As seen in previous helpful content updates, this one really cracked down on content that was poor quality, did not bring value to the user, and was only created with the aim of getting high up the results pages. To beat this helpful content update, content needed to be genuinely beneficial for humans or face big dips in rankings. The search engine confirmed the biggest impact on online educational materials, tech, shopping, and entertainment content and described its effects as being ‘meaningful’ for those affected. To keep the search engine giant happy, website owners must make sure that their material aligns with content quality signals, making sure content is informative and valuable.

August 2023 Core Update

As always, with a core update, this one was all about improving search results to make sure that users receive helpful and relevant results in response to their searches.
Importantly, this update was not a penalty, but the global impact of the August 2023 update was felt far and wide as it affected all types of content in all languages. However, it did have an effect on rankings, as many higher-ranked sites experienced a dip. In contrast, lower-ranked ones saw a positive improvement in rankings, boosting their visibility and having a knock-on impact on traffic. Again, quality, helpful content was the focus if you expected to bounce back from this update.

April 2023 Reviews Update
The Google April 2023 Reviews Update started being rolled out on April 12 and was announced as complete on April 25. This was the second type of reviews-based update of the year. However, there was one slight difference. For this update, Google dropped the word ‘product’ from the update’s name to reflect that it now focused on reviews about pretty much everything, including services, products and other things. It affected reviews in the following languages:
· English
· German
· Spanish
· Italian
· French
· Indonesian
· Dutch
· Vietnamese
· Polish
· Portuguese
· Russian
The review focused on rewarding those who are writing high-quality reviews that demonstrate real insight, analysis and research. There was a clear impact of search results for reviews that did not meet Google’s new criteria.

As with most core updates, organic traffic fluctuations were experienced. Those who were previously lower ranked experienced an uplift, and some saw their rankings drop. To show Google that your website’s content was worthy of being ranked higher up, it must be high-quality, helpful, support E-E-A-T (experience, expertise, authority, and trustworthiness), and provide a strong user experience.
—
February 2023 Product Reviews Update
The Google February 2023 update revolved around product reviews. The first update of the year took 2 weeks to finish – starting on February 21 and ending on March 7. As the name implies, it looked at product review content, assessing it for how helpful reviews actually are to other web users.

· French
· German
· Spanish
· Italian
· Indonesian
· Vietnamese
· Dutch
· Portuguese
· Polish
· Russian
For reviews to be ranked highly in the SERPs, they needed to provide helpful, in-depth details, demonstrate research, show quantitative measurements, and much more.

Google Updates in 2022
2022 had 9 updates throughout the year, with the first update happening in March and the last 1 of the year in December.
Google Spam Update (December 14)
Google released a link spam global update in mid-December, but it wasn’t until January 12, 2023, that the update was finally complete. The update was to improve the automated systems that detect search spam and make it better to spot new types of spam. Any site that violates their updated guidelines could drop rankings or not appear at all.
__
Content Continues To be Impacted By The Helpful Content Update (December 5)
At the start of December, Google released the next Helpful Content update (also completed on January 12, 2023). This sitewide signal update, which targets websites with high volumes of unhelpful content only created for search engines, was rolled out at a global level. Now this update affects all languages. The update is to make it easier for the systems to identify low-quality content on a much larger scale with additional signals to help them find content made for search engines compared to that made for people.
__
Google October 2022 Spam Update
October saw and completed a global spam update affecting all languages and regions in just 2 days. The update was designed to improve spam detection techniques and how they work to target the spam side of search results and reduce the number.

__
September Product Review Update
On September 20, Google set free their 5th Product Reviews update, which ended on September 26. This applied to all English-language product reviews. The update is to further reward high-quality product reviews, promoting them in the search engine rankings. If anyone has seen a dip since this update, working on your product review content is recommended. Google said this update only impacted product review content, but it came out just 6 days into a core update, which was not complete.
__
Core Update In September
On the 12th, the 2nd core update of 2022 came out less than a month after the Helpful Content update in August, taking 14 days to be fully released. While this came fast, in general, this core update had less impact than previous ones had seen, being viewed as a weaker update despite some volatility. This overlapped with the Product Reviews update, which caused a little confusion about which update affected sites. As is the case for many updates, there were many winners of the update who saw decent increases in traffic, but many, even big names, saw declines.
__
August Helpful Content Update
Google unveiled its Helpful Content update to the algorithm in August of 2022. This caused a major stir for all who dealt with content and had websites, as it was a sitewide change that could affect performance and rankings. Being designed to reward content that better meets expectations meant that content that wasn’t achieving this would see a negative impact. Google wanted people to “focus first on creating satisfying content, while also utilizing SEO best practices to bring searchers additional value.” This update only targeted English-language content.
__
Google 4th Product Reviews Update (July 27)
The 4th product reviews update in July was built around updates for English-language product reviews only and to make review-related content more helpful and useful to searchers. This update is not designed to be a penalty but rather a reward for those providing “insightful analysis and original research.” That being said, it could still affect your performance in Google Discover. Although Google would not disclose how many queries would be affected, they did make an interesting announcement about a future update for product review content – a global launch (which then happened in February 2023).
Before this update in July, there were only 3 major Google updates for the first half of 2022:
