Types of Google Updates, Explained
| Type | What it does | How often | What to do if affected |
|---|---|---|---|
| Core update | Broad changes to how Google ranks content overall. Not aimed at specific sites. | Several times a year | Review content quality across the site; avoid quick fixes. |
| Spam update | Improves Google’s systems for detecting pages that break its spam policies. | A few times a year | Find and stop the practice (for example, link schemes or scaled low-value pages). |
| Link spam update | Targets links built to manipulate rankings. | Occasionally | Stop buying or exchanging links; links from spam stop counting. |
| Reviews/product reviews update | Rewards in-depth, first-hand reviews over thin summaries. | Ran 2021-2023 | Add real testing, evidence, and original insight to review pages. |
| Helpful content update | Rewarded content made for people rather than for search engines. | Ran 2022-2023; now part of core ranking | Same as core updates: make content genuinely useful. |
| Discover update | Changes how content is ranked in the Google Discover feed, not regular search results. | Rare | Follow Google’s Discover guidance. |

The dashboard also lists two “ranking is experiencing an ongoing issue” incidents (October 2023 and August 2024). Those were technical problems, not updates, so they aren’t included above.
How Many Times Does Google Update Its Algorithm Each Year?
Counting only the ranking updates Google confirmed on its dashboard:
| Year | Confirmed updates | Core updates | Spam updates (incl. link spam) | Other |
|---|---|---|---|---|
| 2022 | 10 | 2 | 2 | 6 (3 product reviews, 2 helpful content, 1 page experience) |
| 2023 | 9 | 4 | 1 | 4 (3 reviews, 1 helpful content) |
| 2024 | 7 | 4 | 3 | 0 |
| 2025 | 4 | 3 | 1 | 0 |
| Till Nov 2026 | 8 | 3 | 4 | 1 (Discover) |
Google also makes many smaller changes to Search that it doesn’t announce. Google’s own core updates guide describes core updates as happening “several times a year”, which matches the numbers above.
Was My Site Hit by a Google Update? How to Check
- Find the date your traffic changed: In Google Search Console, open Performance > Search results and look at clicks and impressions over the last 16 months.
- Compare it with the timeline above: If the change started during an update’s rollout, the update is a likely cause. Google recommends waiting until the rollout has finished and then at least a full week before comparing data.
- Check whether it’s site-wide or a few pages: Use the Pages tab to see which URLs lost the most clicks. A few pages usually points to content or competition; the whole site at once points to a broader quality issue or a technical problem.
- Rule out technical causes: Check the Pages (indexing) report for new 404s, server errors, or redirects. Our guide to HTTP status codes explains what each one means for SEO, and why Google might not be indexing your site covers indexing problems.
- Check for a manual action: In Search Console, open Security & Manual Actions > Manual actions. A spam update is automatic, but a manual action comes with a notice and can be fixed and reviewed.
What to Do If a Google Update Hurt Your Traffic
After a core update
Google’s guidance on core updates says core updates “don’t target specific sites or individual web pages.” A drop doesn’t mean your site broke a rule; other pages may simply be judged more helpful. Google’s advice:
- Small drop: Google recommends “avoiding making changes to content that’s already performing well.”
- Large, lasting drop: Review your most affected pages and the site as a whole against Google’s helpful content self-assessment questions.
- Avoid quick fixes: Google warns against quick changes and says “deleting content is a last resort.”
- Be patient: Some improvements show within days, but site-wide changes can take several months, and sometimes not until the next core update.
After a spam update
Find the practice that breaks Google’s spam policies and stop it: for example, paid or exchanged links, large numbers of thin pages, or third-party content hosted without oversight. Improvements can take months to show, because Google’s systems need to see the change over time.
Whatever the update
Keep a simple log of your own site changes (redesigns, migrations, content pruning). When traffic moves, you can then tell your own changes apart from Google’s.

Older Major Google Updates (2003-2019)
These updates are widely known by their nicknames. Google confirmed some; the SEO community named others.
| Update | Year | What it was about |
|---|---|---|
| Florida | 2003 | One of the first big updates; hit sites relying on keyword stuffing and other manipulative tactics. |
| Panda | 2011 | Lowered rankings for thin, low-quality, and copied content. Later became part of Google’s core ranking. |
| Penguin | 2012 | Targeted manipulative link building such as paid links and link schemes. |
| Exact Match Domain (EMD) | 2012 | Reduced the advantage of low-quality sites using a keyword-rich domain name. |
| Hummingbird | 2013 | A rebuild of Google’s core algorithm to better understand the meaning of whole queries, not just keywords. |
| Pigeon | 2014 | Changed how Google ranks local results, so local searches work more like regular web searches. |
| Mobile-friendly update | 2015 | Made mobile-friendliness a ranking signal for mobile searches. |
| RankBrain | 2015 | A machine-learning system that helps Google interpret queries it hasn’t seen before. |
| “Medic” | 2018 | The SEO community’s nickname for the August 2018 broad core update, which hit many health, finance, and other “your money or your life” sites. |
| Mobile-first indexing | 2018 | Google began using the mobile version of a page for indexing and ranking. It rolled out gradually over the next few years. |
| BERT | 2019 | Bidirectional Encoder Representations from Transformers: a language model that helps Google understand the context of words in a query. |
About E-E-A-T: In December 2022, Google added “Experience” to E-A-T, making it E-E-A-T, in its Search Quality Rater Guidelines. This was a change to the guidelines that human raters use to evaluate results, not an algorithm update, and Google says the guidelines “don’t directly influence ranking.”
How to Stay Updated on Google Algorithm Changes
Google doesn’t send a notification when an update starts, so you have to know where to look. Three places cover almost everything. The Google Search Status Dashboard is the main one. Google lists confirmed ranking updates there with start and end dates, and that’s where we take the dates in this post from.
The Google Search Central blog is where Google explains bigger changes, such as new spam policies or changes to how core updates work. Google Search Console is where you see what an update did to your own site. If you check your performance report every week, you’ll notice a sudden change early instead of weeks later. Bookmark this page too. We update it whenever Google confirms a new ranking update.

It varies. Google says some improvements can show within days, but site-wide improvements can take several months to be recognized, and in some cases a site may not see a change until the next core update.
