How Google’s Algorithm Changes Over Time, and How to Stay Ahead of Updates

Google algorithm updates are changes to the systems Google uses to rank search results. Most are small and never announced. Several times a year, Google confirms core and spam updates on its Search Status Dashboard. In 2025 it confirmed three core and one spam update. By October 2026 it had confirmed two core, four spam and one Discover update.

What are Google algorithm updates?

A Google algorithm update is a change to how Google finds, judges and orders pages for a search. Small changes ship all the time without notice. Larger ones, such as core and spam updates, are confirmed with a start date and a rollout period.

The word “algorithm” is a little misleading. Google does not run one formula. It runs many ranking systems that each look at different signals, such as relevance, quality, freshness and spam. An update changes one or more of these systems. If you want the basics of how those systems work together, our guide to how Google ranks and displays results explains them in more detail.

For a business, an update can move your pages up or down even when you changed nothing. That is why it helps to know what kind of change happened before you react. This guide sits within our wider explanation of what SEO is and how it works for businesses in Dubai and Abu Dhabi.

How often does Google change search?

Google launches thousands of changes to search each year, but it confirms only a handful as named updates. In 2023, Google ran 4,781 launches, 16,871 live traffic experiments, 719,326 search quality tests and 124,942 side-by-side experiments. Only a few of those changes became named, confirmed updates.

Thousands of tests behind the scenes

Google publishes its testing numbers on its rigorous testing page. Search quality tests use trained raters who judge results against written guidelines. Live traffic experiments show a change to a small share of users and measure the result. Side-by-side tests compare two sets of results for the same query.

Because changes ship this often, daily movement of a few positions is normal. On its own, it does not mean an update hit you.

A few confirmed updates each year

The bigger changes appear on the Google Search Status Dashboard. Google’s own core updates documentation says core updates happen several times a year. The dashboard data backs that up: three core updates in 2025, and two by October 2026.

The answer to “how often does Google update its algorithm” has two parts. It changes constantly in small ways. It changes in big, confirmed ways only a few times a year.

The four kinds of change you will see

Changes that affect your search traffic fall into four groups. They are core updates, spam updates, targeted system updates such as Discover, and changes to the results page itself, such as AI Overviews. Each one needs a different response, so naming the type comes first.

Core updates

Core updates are broad changes to Google’s main ranking systems. They do not target one type of site or one tactic. Google reassesses how well pages meet search intent and how helpful and reliable they are. Some pages gain, some lose, and many do not move.

Spam updates

Spam updates improve Google’s automated systems for catching content that breaks its spam policies. Those policies cover cloaking, doorway abuse, expired domain abuse, link spam, scaled content abuse, site reputation abuse and thin affiliation, among others. The policies page is the list to compare your own site against.

Targeted system updates

Some updates change one specific system or surface. The February 2026 Discover update is an example. It started on 5 February 2026 and took 21 days and 17 hours to roll out, according to the dashboard. It affected Google Discover, the feed of suggested content on phones, rather than normal search results. Past examples include the reviews updates of 2022 and 2023.

If your Discover traffic moved in February 2026 but your search traffic did not, this is the likely reason. Check the Discover report in Search Console separately from the Search results report.

Changes to the results page

The fourth kind is not a ranking update at all. Google adds or changes features on the results page, such as AI Overviews, People Also Ask boxes and other panels. Your page may keep its position but get fewer clicks, because the answer now appears higher up. Our guide on how Google AI Overviews work and which sources get cited explains this shift. We return to it in the Search Console section below.

A short history: from Panda and Penguin to helpful content inside core ranking

Google’s updates have moved from separate, named filters to systems built into core ranking. Panda (2011) targeted low-quality content and Penguin targeted link spam, and Google now lists both, along with Hummingbird, as retired systems. The helpful content system became part of core ranking in March 2024.

This matters because many articles still describe these as separate updates you can “recover from” one by one. Google’s ranking systems guide is clear: the helpful content system became part of its core ranking systems in March 2024. There is no longer a separate helpful content update to wait for.

Date	Change	What it means today
2011 onward	Panda, aimed at low-quality content, and Penguin, aimed at manipulative links	Both listed by Google as retired systems
Aug 2022	First helpful content update on the dashboard (15 days)	Introduced the people-first content idea
Sep 2023	Helpful content update (13 days, 11 hours)	The last one before helpful content joined core ranking
Nov 2023	Reviews update (29 days)	A targeted update for review content
Mar 2024	Core update (45 days), helpful content folded into core	Marked the move to today’s model
Dec 2025	Core update (18 days, 2 hours)	Current model: broad core updates plus spam updates

When Google announced the March 2024 update, it said it expected a 40% cut in low-quality, unoriginal content in results. It later reported a 45% reduction, according to its March 2024 Search update post. That update marked the shift to the model we see today.

What the 2025 and 2026 updates tell us

The Search Status Dashboard lists 11 confirmed ranking updates from January 2025 to October 2026. Core updates took 11 to 18 days to roll out, while spam updates ranged from 19 hours to more than 26 days. As of 28 October 2026, no ranking update had been confirmed after the September 2026 spam update.

Update	Start date	Rollout length
March 2025 core update	13 Mar 2025	13 days, 21 hours
June 2025 core update	30 Jun 2025	16 days, 18 hours
August 2025 spam update	26 Aug 2025	26 days, 15 hours
December 2025 core update	11 Dec 2025	18 days, 2 hours
February 2026 Discover update	5 Feb 2026	21 days, 17 hours
March 2026 spam update	24 Mar 2026	19 hours, 30 minutes
March 2026 core update	27 Mar 2026	12 days, 4 hours
May 2026 core update	21 May 2026	11 days, 21 hours
June 2026 spam update	24 Jun 2026	2 days, 1 hour
August 2026 spam update	18 Aug 2026	2 days, 16 hours
September 2026 spam update	24 Sep 2026	13 days, 16 hours

Three patterns worth knowing

First, core updates now arrive two or three times a year. That is a calmer pace than the four core updates Google confirmed in 2024.

Second, rollouts take time. In 2025 and 2026, core updates took 11 to 18 days to finish. Rankings often move up and down during that window. Judging the result on day three gives you a false picture.

Third, spam updates have become more frequent in 2026, with four by October. Several were short. Their target is the practices the spam policies describe.

Was it the update? Six checks before you change anything

Before you blame an update, rule out the other causes of a traffic drop. Check tracking, indexing and technical health, seasonality, results page changes, competitors, and finally the update dates. Any of the first five can look like update damage.

Work through the checks in order and stop at the first one that explains the drop.

1. Tracking

Check that your analytics still records data correctly. A removed tag, a consent banner change or a new site template can cut reported traffic overnight. Compare analytics sessions with Search Console clicks. If Search Console looks steady but analytics fell, the problem is tracking, not Google.

2. Indexing and technical health

Open the Page indexing report in Search Console. Look for a jump in pages marked noindex, blocked by robots.txt or returning server errors. Site migrations, redirect chains and broken canonical tags can all cause sudden drops. A technical SEO review can confirm whether Google can still crawl and index your key pages.

3. Seasonality

Demand in the UAE shifts with the calendar. Ramadan can change when and what people search. The summer months can slow some sectors as residents travel. Compare the same period last year, not just the previous month. If last year showed the same dip, the update may not be the cause.

4. Changes to the results page

Search for your main keywords and look at what appears above your listing. A new AI Overview, ads block or feature can push you down the screen without any ranking change. This shows up as steady impressions with falling clicks.

5. Competitors

Check who now ranks above you. A competitor may have published a better page, earned new links or launched a new site. That is a ranking change, but it is not something an update did to you. The fix is to improve your page, not to undo past work.

6. Update dates

Only now compare your drop with the dashboard table above. Does the decline start within the rollout window of a confirmed update? Does it affect many pages across the site rather than one or two? If both answers are yes, an update may be the cause, and the next section shows how to read the data.

Reading Search Console after an update

Wait until the rollout has finished, then wait at least one more full week. Compare equal periods before and after, and split the data by clicks and impressions, by page and by query. Google’s own core updates guidance recommends this approach.

Wait, then compare equal periods

Google’s core updates documentation advises waiting at least a full week after an update completes before you analyse Search Console. Compare the week after with a week before the rollout began, of the same length. Use the same days of the week. In the UAE, avoid comparing a Ramadan week with a normal week.

Split impressions from clicks

Look at the clicks line and the impressions line on their own.

• Impressions and clicks both fell: you likely lost positions. This points to a ranking change, possibly the update.
• Impressions stayed flat but clicks fell: you kept your positions but lost the click. This points to a results page change, such as an AI Overview or a new feature.
• Both stayed flat but analytics fell: go back to the tracking check.

Losing rankings and losing clicks need very different responses. Rewriting a page will not bring back clicks taken by a new results feature.

Split pages from queries

Open the Pages tab and sort by the change in clicks. Is the drop spread across the whole site or limited to a few pages? Then check the Queries tab. A drop in one topic suggests a relevance issue on those pages. A drop across every topic suggests a site-wide quality reassessment, which may point to a core update. Google’s documentation also says a small drop, such as from position 2 to 4, needs no drastic action.

Core update, spam update or manual action?

A core update reassesses quality, a spam update applies spam policies automatically, and a manual action is applied by a human reviewer. You find a manual action in Search Console, but you can only infer a core or spam update from the timing. The right response differs for each.

	Core update	Spam update	Manual action
What it targets	Overall quality and relevance	Breaches of the spam policies	Breaches of the spam policies, confirmed by a person
Who decides	Automated ranking systems	Automated spam systems	A human reviewer at Google
How you find out	Timing matches a dashboard rollout	Timing matches a dashboard rollout	Manual actions report and Search Console messages
What to do	Improve content quality and usefulness	Remove the spam practice	Fix every affected page, then request a review
How long	Often months, sometimes the next core update	After systems see the fix	Review takes several days or weeks

Core update

A core update does not single out your site. Google reassesses content, and other pages may now serve the query better. The response is a fair look at your content compared with what now ranks. Ask whether your pages show first-hand experience, answer the question fully and stay accurate and current. Our guide to Google’s search quality evaluation principles covers what raters look for.

Spam update

A spam update hurts sites that use tactics the spam policies describe. Common causes are paid or swapped links, mass-produced pages and hosting third-party content to exploit your site’s reputation. The fix is to stop the practice and remove the problem content.

Manual action

A manual action is different, because a person at Google reviewed your site. Google’s Manual actions report help page says you are told in the Manual actions report and the Search Console message centre. Once every listed issue is fixed on all pages, you request a review and explain what you did. Google says most reconsideration reviews take several days or weeks. If you have a confirmed manual action and need help with the fixes and the request, our Google penalty recovery service covers the fixes and the request.

What recovery looks like and how long it takes

Recovery from a core update is usually slow: Google says improvements can take several months to show, and some sites may not see a change until the next core update. Recovery from a manual action depends on a successful review. Small drops often need no action at all.

Google’s core updates guidance makes three points worth keeping in mind. Core updates do not target specific sites, so a drop does not mean your page is bad. Other pages may simply serve the query better now. Some changes take effect in a few days, but it can take several months for Google’s systems to confirm the improvement.

A sensible order of work looks like this:

1. Confirm the cause with the six checks and the Search Console split.
2. Fix technical or indexing faults first, because they block everything else.
3. Remove any spam policy problems.
4. Review the pages that lost most, comparing them honestly with the pages that now rank.
5. Improve those pages and give the changes time to be reassessed.

What to ignore matters as much. Ignore daily rank swings during a rollout. Ignore early social media claims about what an update “targeted”. Ignore advice to rewrite every page at once. If you are unsure where the problem sits, an SEO audit and diagnostic review can rank the issues by impact.

How to stay ahead: a resilience plan for UAE businesses

You cannot predict the next update, but you can build a site that tends to do well across them. Focus on useful, people-first content, first-hand experience, clean links, sound bilingual pages, a strong Google Business Profile and traffic from more than one channel.

People-first content with real experience

Write for the customer first. Show what you know from doing the work: your process, real examples and clear answers. Name the author and explain why they are qualified. Google’s core updates guidance points site owners to this kind of people-first content.

Clean links

Earn links through useful content, partnerships and genuine press coverage. Avoid paid link packages and link swaps. These are the practices that spam updates and manual actions catch.

Sound bilingual pages

Many UAE businesses run Arabic and English versions of their site. Give each language its own URL, such as an /ar/ subfolder, and connect the versions with hreflang tags. Translate fully rather than mixing languages on one page. A broken language setup can look like an update drop when it is really a technical fault.

Google Business Profile as a buffer

For local businesses in Dubai, Abu Dhabi and across the GCC, the local pack and Google Maps bring calls and visits that do not depend only on organic rankings. Keep your profile complete, keep hours current and reply to reviews. This keeps leads coming when organic rankings shift.

More than one channel

Do not let one source carry the whole business. Email lists, social channels, referrals and paid search all reduce the impact of any single update. A few weeks of lower organic traffic then hurts less.

A monitoring routine you can keep

Check the Search Status Dashboard and the Search Central blog for confirmed updates, and log each date next to your own traffic data. Review Search Console weekly. Use volatility tools as an early signal, not as proof.

A simple monthly routine works for most businesses:

• Weekly: look at Search Console clicks and impressions for your top pages and queries.
• When an update is confirmed: add the start date as a Google Analytics 4 annotation. Add the end date when the dashboard shows it complete.
• One week after a rollout ends: run the equal-period comparison described above.
• Monthly: compare with the same month last year to account for Ramadan and summer patterns.
• Quarterly: review your weakest pages and refresh or merge them.

The Google Search Central blog is where Google explains policy and product changes in more depth. Third-party volatility trackers, such as Semrush Sensor or MozCast, show when rankings move across many sites. Treat them as a prompt to look at your own data, not as a diagnosis.

Worldwide Google Trends data for October 2025 to October 2026 shows interest in core updates spiking as each one lands, then falling back. For most of the year, there is no confirmed update to react to.
