Google released two broad core updates this year: the March 2026 core update, which ran from March 27 to April 8, and the May 2026 core update, which ran from May 21 to June 2, according to Google’s Search Status Dashboard. The short version of the Google core update 2026 story is that May mattered far more than March. To tell whether either one hit your site, compare your Search Console data for the weeks before and after each rollout, then rule out seasonality, technical problems and manual actions before you change anything.
Most local businesses won’t need a recovery plan. Google says core updates don’t target individual sites, and in Raptive’s study of more than 4,000 sites, 70% improved or held steady through the May update. But if your leads dipped in June, the steps below show how we check whether the update was the cause, using a real dental practice’s Search Console data.
Google’s Search Status Dashboard lists every confirmed ranking update with its start date and how long it took to roll out. Captured November 3, 2026.
What is a Google core update?
A core update is a broad change to how Google’s ranking systems judge content across the whole web, and Google releases several a year. It isn’t a penalty and doesn’t single out sites, so a drop often means other pages were judged more useful for those searches, not that Google flagged yours.
Google’s core updates documentation says the changes are broad, don’t target specific sites or pages, and that a page which moves down isn’t necessarily bad. That makes a core update different from the two things owners often confuse it with. A spam update targets practices that break Google’s spam policies, and a manual action is issued when a human reviewer at Google decides your pages break those policies, which shows up in Search Console’s Manual actions report.
The practical difference for a local business is the fix. A manual action tells you what’s wrong. A core update sends no message at all, so you have to work out from your own data whether it touched you.
Which core updates did Google release in 2026?
Two: the March 2026 core update, which started on March 27 and took 12 days, and the May 2026 core update, which started on May 21 and took 12 days. Google also ran a Discover-only update in February and four spam updates, the last of which finished on October 8.
Here’s every ranking update on Google’s Search Status Dashboard since December 2025, and what each one means for a local business website.
| Update | Started, and how long it ran | What it means for a local business site |
|---|---|---|
| December 2025 core update | December 11, 2025, 18 days | Broad; a dip in early January may trace back to it, or to the usual post-holiday lull |
| February 2026 Discover update | February 5, 22 days (done February 27) | Affects the Discover feed only; most local sites won’t notice |
| March 2026 spam update | March 24, under a day | Spam policies; unlikely to matter unless you used spammy tactics |
| March 2026 core update | March 27, 12 days (done April 8) | Broad but mild for most sites |
| May 2026 core update | May 21, 12 days (done June 2) | Broad and much stronger; the one to check first |
| June 2026 spam update | June 24, 2 days | Spam policies |
| August 2026 spam update | August 18, 3 days | Spam policies |
| September 2026 spam update | September 24, 14 days (done October 8) | Spam policies; see our September 2026 spam update guide |
Google hasn’t confirmed any ranking update for October 2026. If your traffic moved last month, look at the other causes below before blaming an algorithm change.
How was the May 2026 core update different from March?
May was the stronger update by a wide margin. Glenn Gabe of GSQi saw big swings within about 48 hours of launch, especially in health, finance and gambling, while March produced only modest movement for most sites.
His analysis of the May update describes March as mild and May as far more powerful, with early movement in health and finance, very large swings for gambling sites and a heavy loss for a site that had scaled lower-quality content through AI translation. Search Engine Roundtable’s report on the March update noted it took 12 days and 4 hours and didn’t seem as powerful as December 2025’s.
Most sites still came through fine. Raptive found that 70% of its 4,000+ sites improved or held steady in May and about a third saw meaningful declines, with lower ad density among the clearest signals of the sites that did well. Raptive’s sites are ad-supported publishers rather than local businesses, so read that as a reminder not to panic rather than as a benchmark for your own site.
How do you tell if a core update hit your site?
Line up your Search Console data with the rollout dates, then rule out everything else. If clicks or impressions fell sharply during or just after a rollout, across a group of pages, with no technical problem, manual action or seasonal pattern to explain it, the update is the likely cause.
- Get the dates right. Check the Search Status Dashboard for when each update started and finished. Google recommends waiting at least a full week after a rollout completes before you analyze anything.
- Compare equal periods in Search Console. Open Performance, then Search results, then Date and the Compare tab. Google’s example compares a week after the update with the week before it. For small local sites we compare 28 days on each side, because a single week of data is noisy, and we leave the rollout days out of both periods.
- Look at the shape. Google’s guide to debugging traffic drops says a sudden large drop points to an algorithm update, a security issue or spam, a gradual decline to a technical issue or changing interest, and a dip that repeats at the same time each year to seasonality.
- Find where the change happened. Click through the Queries and Pages tabs and sort by the clicks difference. Check whether a type of content or a group of pages moved together, which is what we usually see after a core update, or just one page. Add a query filter for your town’s name or “near me” to see whether the searches that bring customers moved, or only the general ones.
- Rule out other causes. Check the Manual Actions, Security Issues and Page indexing reports, and list anything you changed: a redesign, new URLs, a plugin, a robots.txt edit. In our experience, if a drop shows in Google Analytics but not in Search Console, a broken tracking tag is the usual cause.
- Check last year. Compare the same weeks year over year, and look up your main services in Google Trends. Plenty of local services have quiet months.
- Judge the size. Google’s core updates guidance gives its own example: slipping from position 2 to 4 needs no drastic action, while a fall from 4 to 29 deserves a deeper look.
What did the May 2026 core update look like on a real local site?
For one family dental practice we work with, it looked alarming and turned out to be mostly harmless. Impressions fell 28% and average position slipped from 16.6 to 23.7, but clicks held steady, because most of the lost visibility came from searches that had never sent a visitor.
We compared the 28 days before the rollout (April 23 to May 20) with the 28 days after it finished (June 3 to 30). Impressions fell from 56,921 to 41,205, while clicks went from 206 to 209. The March update had barely registered on the same site: over the same 28-day windows around it, clicks dipped from 219 to 197 while impressions rose from 53,911 to 57,031, and average position barely moved (13.8 to 14.8).
Breaking the drop down by query and page showed what had happened:
- About half of all the lost impressions came from one “family dentist” search for the practice’s city. It hadn’t produced a single click in either period, and the homepage it pointed to actually gained clicks, from 44 to 53.
- The real loss was one general article about the types of dental specialists. Its impressions roughly halved and its clicks fell from 29 to 9, while broad questions like “types of dentists” slid from page 2 to page 4.
- Seasonality explained the rest. The same weeks in 2025 had seen clicks fall 29%, so flat clicks in June 2026 were a reasonable result.
In July we reworked the practice’s main service pages, including implants, sedation dentistry and crowns, tightened internal links and published community pages. In August we reviewed the informational articles that earned impressions but few clicks. By September the site had 369 clicks and 65,629 impressions, with an average position of 12.4, compared with 245 clicks in April before the update and 226 in September 2025. No core update happened in between, only spam updates. We can’t prove which change did the most, but the timing fits Google’s advice that improvements can show between core updates.
Monthly Search Console clicks and impressions for a family dental practice we work with, January to October 2026, with both core update rollouts shaded. Name withheld.
Is a drop in Google Maps the same as a core update hit?
Usually not, though the two can overlap. Core updates change how Google ranks web pages, while the map pack runs mainly on relevance, distance and how well known your business is, so a Maps drop with steady website traffic usually points to your Business Profile.
Google’s local ranking help page lists relevance, distance and prominence as the main local factors, and says prominence draws on things like how many websites link to your business and how many reviews you have. That’s where the overlap comes from: links that help your website can help your map ranking too. So check two sets of numbers separately: Search Console for your website, and your Business Profile’s performance report for calls, direction requests and website clicks. Adding UTM tags to the website link on your profile keeps those visits apart from organic search in Google Analytics, which makes the next check much quicker.
If the profile numbers fell and Search Console didn’t, look at the profile before you blame an update. Check for a suspension, an edit to your category or hours you didn’t make, a change in your reviews or a new competitor close by. Our Google Business Profile checklist covers every field worth checking.
Can you recover from a Google core update?
Yes, and you don’t always have to wait for the next one. Google says improvements can take effect within a few days or take several months, and that if nothing changes after a few months you may need to wait for the next core update.
Google’s core updates guidance also warns against quick fixes, says to avoid changing content that’s already performing well, and calls deleting content a last resort. That rules out the usual panic moves: rewriting every page at once, deleting half the blog or buying links.
The dental practice above got its impressions and rankings back, and grew its clicks, in about three months without another core update. That’s one site, not a promise, but it shows recovery comes from the site getting better rather than from Google reversing anything.
What should a local business fix after a core update?
Fix the pages that lost real visitors, not the impressions nobody clicked. For most local sites that means service pages with more first-hand detail, clear authorship, and improving or merging thin general articles that compete with national publishers.
Google’s guide to creating helpful content asks whether your content offers original information, shows first-hand expertise, makes it obvious who wrote it, and whether it was made mainly to attract search visits. For a local service business, that turns into four jobs:
- Make service pages answer buyer questions. Price ranges, how the job works, the areas you serve and photos of your own work, written by people who do the work.
- Show who’s behind the advice. Name the owner, dentist or technician and their experience on the pages that give advice.
- Be honest about general articles. A local practice rarely outranks national health or trade sites for “what is” questions. Keep the articles that bring customers, and improve or merge the rest.
- Edit AI drafts with real experience. Google updated its guidance on using generative AI content on October 1, 2026 with information from its Search Quality Rater guidelines, according to its documentation updates log.
Then keep measuring with the same 28-day comparison every month, so the next update has a clean baseline to compare against.
What else do owners ask about Google core updates?
The questions below come straight from what people search on Google about core updates. Here are short answers to the six that come up most.
Is there a Google core update happening now?
Not as of November 3, 2026. The last core update was the May 2026 core update, which finished on June 2, and the last ranking update of any kind was the September 2026 spam update, which ended on October 8. Google’s Search Status Dashboard shows any rollout in progress.
How often does Google release core updates?
Several times a year, according to Google. Its Search Status Dashboard lists three in 2025 (March, June and December) and two so far in 2026 (March and May).
Is a Google core update a penalty?
No. Google says core updates don’t target specific sites or pages. A penalty from Google is a manual action, which shows up in the Manual Actions report in Search Console.
How do I know if Google penalized my site?
Open Search Console and go to Security and Manual Actions, then Manual actions. If it shows a green check mark and says there are no issues, you don’t have a manual penalty, and a drop is more likely an algorithm update, a technical problem or seasonality.
Can you undo or opt out of a Google update?
No. There’s no setting, appeal or request that reverses a core update for your site. What you can change is the site itself, and Google says improvements can show before the next core update.
How long does a Google core update take to roll out?
About two weeks. The March 2026 core update took 12 days and 4 hours and the May 2026 core update took 11 days and 21 hours, while the December 2025 update took just over 18 days.
