Many Google algorithm updates have caused massive and sudden changes in the SERPs for the past few years. Google confirms several ranking updates a year, and the biggest can move traffic within days. In 2026 alone it ran core updates in March and May, and spam updates in March, June, August and September.

Google continues to focus on SERPs question-answer and continues to offer additional query matches in its “People also search for” feature.

Often, it feels like SEO is just an endless dance between constantly moving targets. Whenever you think you’ve hit your stride with a particular strategy, Google updates its algorithm, and everything changes.

Ever since the patenting of PageRank, you’ve been living in a world of constant change, and the impact of algorithm updates has become more pronounced as well.

Google makes thousands of changes to Search every year, and confirms only the larger ones. Google is constantly making changes to its algorithm. These changes aim to bring quality content to the top of search results and make it easier for users to find what they want.

It needs to maintain its credibility and integrity. The company monitors all its products and ensures they are up-to-date with the latest trends. But this also means several changes must be made to keep up with the changing times.

These changes are made through algorithmic updates. Algorithms are mathematical formulas that help computers solve problems. Google uses algorithms to process information in its database and make it available to users when they type a query into the search engine.

One important thing about Google algorithm updates is that they’re not all black and white. They’re not just good or bad – they’re somewhere in between.

If you’ve ever heard someone say, “The latest Google update killed my website,” then you know that not all algorithm changes are bad news. Some are very helpful for SEOs and webmasters by making it easier for search engines to crawl websites and index content.

For example, when Google introduced its Accelerated Mobile Pages (AMP) project in 2015, it made it easier for users by speeding up their mobile browsing experience and making it easier for search engines like Google or Bing to crawl those pages without having any impact on the user experience.

Major Google Ranking Updates Since 2022

Google lists every confirmed ranking update, with start and end dates, on the Google Search Status Dashboard. Since 2022 the confirmed updates fall into three groups: core updates, spam updates, and systems such as helpful content and reviews that Google later merged into its core ranking. These are the ones that mattered most.

Helpful Content System (August 2022)

Google announced it on 18 August 2022 and started the rollout on 25 August. It added a site-wide signal that rewards content written for people and demotes content made mainly to rank in search. In March 2024 Google made it part of its core ranking systems, so it no longer has separate updates.

Product Reviews Updates (2022)

Google released product reviews updates in March, July and September 2022. They rewarded reviews that show real, first-hand experience with a product. Google later moved this into a reviews system and stopped announcing separate reviews updates.

Announced on 14 December 2022, it used Google’s SpamBrain system to find unnatural links and stop them from passing credit. Links built only to influence rankings lose their value, and sites that depended on them can lose rankings.

March 2024 Core and Spam Updates

The March 2024 core update started on 5 March 2024 and finished on 19 April 2024. Google said it aimed to show less unhelpful, unoriginal content. At the same time it announced new spam policies against scaled content abuse, site reputation abuse and expired domain abuse. The helpful content system became part of the core update from this point.

Core Updates in 2025

Google confirmed three core updates in 2025: March (13 to 27 March), June (30 June to 17 July) and December (11 to 29 December).

Core and Spam Updates in 2026

The core updates of 2026 ran from 27 March to 8 April and from 21 May to 2 June. Google also confirmed spam updates starting on 24 March, 24 June, 18 August and 24 September 2026, plus a Discover update from 5 to 27 February. Spam updates target content and links that break Google’s spam policies, such as scaled low-value pages and manipulative links.

Why are Google Algorithm Updates Necessary?

Google mainly aims to provide users with relevant information as quickly as possible. To do so, they continuously monitor their search results and adjust their ranking signals accordingly.

It’s only natural that they would want to improve their existing algorithms by adding new ones, eliminating old ones, or making changes to existing ones.

Google has three main goals when it comes to algorithm updates:

  • Provide users with the best experience possible
  • Protect users from spammy content and sites
  • Improve user trust in Google search results

Google’s mission is to organise the world’s information and make it universally accessible and helpful. To accomplish this goal, the search engine giant has developed several algorithms to determine how pages are ranked in search results.

These algorithms are constantly improved based on new data from user behaviour and online trends.

You may wonder why Google needs so many different algorithms when its primary goal is organising information. The answer is simple: Google needs multiple algorithms because people use numerous ways to interact with search engines daily!

Impact of Google Algorithm Updates on SEO

Impact of Google Algorithm Updates on SEO

Google is the most popular and powerful search engine on the planet, meaning any change it makes to its algorithm can majorly impact your website. The primary purpose of these algorithmic updates is to ensure that the quality of search results remains high and relevant.

So, whenever Google does any update, it significantly impacts SEO (Search Engine Optimisation) strategies and traffic generated from search engines by websites.

This is particularly true if you run an e-commerce site or an online business that relies heavily on organic traffic for growth.

There are several changes that Google has made over the years that have had a significant impact on SEO; some have been good, others bad, but all have caused SEO professionals to rethink their strategies.

How Google Algorithm Updates Affect Your Site’s Positioning

How Google Algorithm Updates Affect Your Site's Positioning

Google updates can be divided into the core algorithm and regular, minor updates. The core algorithm updates are applied to all searches and are intended to affect all websites equally.

The other updates are specific to certain queries (such as local search or news).

Core Algorithm Updates

These are broad updates to the main ranking systems. Google has confirmed several a year recently, and each one takes roughly one to three weeks to roll out.

They roll out gradually, so rankings can keep moving until Google marks the update as finished.

Spam Updates

These go after content and links that break Google’s spam policies. They are usually shorter than core updates, and Google ran several in 2026 alone. They focus on specific problems instead of re-ranking every kind of page.

The bad news is that nobody can know in advance when Google will release an update or how much it will change your rankings. The good news is that you can prepare by knowing which types of sites tend to be affected by which types of updates and what to do once one hits your site.

Tips to Make Google Algorithm Updates Work for SEO

Tips to Make Google Algorithm Updates Work for SEO

Google changes its algorithm frequently and keeps a tight lid on what goes into it, but we know that Google wants to give people the best possible experience when they search online.

Whenever Google makes an update, it’s likely to impact your website in one way or another – either positively or negatively. The good news is that these updates aren’t permanent and can often be fixed if you know what to look for.

Many factors affect how Google ranks your website, but the most important one is the quality of your website. A good website will rank higher than a poor one in Google’s eyes and get more traffic.

The more traffic you get from Google, the more money you make off it, right? So let’s see what we need to do to improve our rankings on Google.

Know When an Update Is Rolling Out

Google does not announce updates in advance, but it confirms the larger ones on the Google Search Status Dashboard when they start and again when they finish. Check it whenever your traffic changes sharply.

Wait until the rollout has finished, then compare your Search Console performance with an equal period before the update. A drop that began before the update’s start date was not caused by it.

Stay Wary of Low-Quality Content

Core and spam updates both go after low-quality, unoriginal and scaled content, so make sure yours doesn’t fall into this category.

Publish original pages made for a real audience, and edit them before they go live. Don’t mass-produce pages or rewrite other sites’ content with AI.

Be on Google’s Good Side

If a site has been penalised, it’s not because of one lousy link or one piece of content. It’s more likely that the site has been involved in suspicious behaviour over time — for example, building links in ways that violate Google’s guidelines.

Sites penalised by Google usually have hundreds or thousands of unnatural links pointing at them from sites that violate Google’s guidelines.

Check Your Search Console Data

First, check your site’s crawl stats in Google Search Console (formerly Webmaster Tools). This will show how many URLs were crawled by Googlebot during a fixed period (usually one month).

If you see a sudden drop in the number of URLs visited by Googlebot, this could indicate an update that affected the indexation rate for specific pages or pages in general.

Wrapping Up

The algorithm is constantly changing, so it’s hard to track the true impact of a new update or when it will end—but one thing is sure: changes like these are never permanent.

The algorithms that Google uses for search are constantly shifting, evolving, and improving to respond to internet trends, changes in web usage, and fluctuations in search volume.

Each update is another step towards Google’s long-term goal of showing the most relevant and reliable information. Sites built for people, with original content and clean links, have the least to fear from the next one.
