Before 2018, most SEOs treated a ranking drop like a puzzle with a hidden answer: find the "penalty", fix the cause, recover. In March 2018 Google publicly confirmed a broad core update and, for the first time in that form, told site owners there might be nothing to fix at all. That message changed how the industry talks about core updates to this day.
The update itself rolled out from around 8 March 2018 for almost two weeks. The industry nicknamed it "Brackets", a name credited to SEO consultant Glenn Gabe. Google simply called it a broad core algorithm update.
In this article you will learn what was confirmed, what Google's "no fix" guidance actually said, why it was such a shift, and how to apply that guidance sensibly in 2026 without ignoring real problems on your site.
Key Takeaways
- Google confirmed a broad core update in March 2018; update histories date it to around 8 March, rolling out for almost two weeks.
- "Brackets" was an industry nickname, credited to Glenn Gabe; Google did not use it.
- Google said there was no "fix" for pages that performed less well, other than to keep building great content.
- Google also said the changes benefited pages that were previously under-rewarded, so drops did not necessarily mean a site did anything wrong.
- Google reused this guidance for later core updates, and in 2019 expanded it with self-assessment questions.
The March 2018 core update at a glance
| Item | Details |
|---|---|
| Name | Broad core algorithm update (Google); "Brackets" (industry nickname credited to Glenn Gabe) |
| Start date | Around 8 March 2018, per Clickintelligence's update history and Wikipedia's Timeline of Google Search |
| Rollout | Almost two weeks, according to Clickintelligence |
| Google confirmation | Via the Google SearchLiaison account; Search Engine Journal reports Google's guidance dated 12 March 2018 |
| Type | Broad core update (not a penalty, not targeted at specific sites) |
| Confirmed by Google? | Yes |
Google gave no figure for how many queries were affected and did not name any target. That was deliberate: Google described broad core updates as routine changes it makes several times a year, rather than as targeted systems like Panda or Penguin.
Google's "no fix" message
The most important part of this update was not the ranking movement but what Google said about it. Search Engine Journal quotes the guidance Google posted on 12 March 2018:
“There's no "fix" for pages that may perform less well other than to remain focused on building great content.”

Google also said that changes to its systems were benefiting pages that were previously under-rewarded. Put simply, if your page dropped, it might be because other pages were now judged more relevant, not because yours had been demoted for a fault.
This was a big change in tone. For years, SEOs had been conditioned by targeted updates where there often was something specific to fix, such as manipulative links or thin pages. The March 2018 message separated core updates from penalties and manual actions. Our explainer on Google's "no fix" core update guidance traces how this wording has evolved.
How the message changed SEO thinking
| Before March 2018 (common SEO assumption) | Google's March 2018 message | What it means in practice |
|---|---|---|
| A drop means a penalty or a specific mistake | Pages that perform less well may not be doing anything wrong | Diagnose before "fixing"; a drop can reflect competitors being rewarded |
| Find the one technical fix and rankings return | There is no "fix" other than building great content | Focus on the overall quality and usefulness of affected pages |
| Updates mainly punish | Changes benefit pages that were previously under-rewarded | Look at who gained, not just who lost |
| Recovery happens as soon as the issue is fixed | Content may rise relative to other pages over time | Be patient; improvements may take time to be reflected |
The guidance became a template. When Google confirmed the August 2018 core update, it said its guidance remained the same as in March. When it began naming updates by month with the March 2019 core update, it again pointed back to this advice. Then, in August 2019, Google published a fuller post on core updates with a list of self-assessment questions about content quality. Search Engine Land described that as a change from the earlier "nothing to fix" framing.
Google's current documentation keeps the spirit of the 2018 message while being more practical. It says that most sites don't need to worry about core updates, that site owners should avoid "quick fix" changes, and that some improvements may only be reflected after a later core update.
What "no fix" does not mean
The phrase is easy to misread. It does not mean nothing about your site matters. It means there is no single switch to flip. In practice:
- Content quality, expertise and usefulness still matter, and often matter most.
- Technical problems (blocked pages, broken templates, indexing issues) are still worth fixing, but they are usually not what a core update is "about".
- A drop can be relative: competitors improved, or Google better understood which pages answer a query.
- Recovery, if it comes, tends to follow genuine improvement, often around a later core update rather than immediately.
A practical response to a core update drop
- Wait until the update has finished rolling out before drawing conclusions; Google recommends waiting at least a full week after completion before analysing.
- Compare a period before the update with a period after it in Search Console, at page and query level.
- Look at who gained for your lost queries and what their pages do better for the searcher.
- Assess your affected pages honestly against Google's helpful content questions.
- Prioritise meaningful improvements to your most valuable pages over cosmetic edits across the site.
- Fix any genuine technical problems you find, but do not expect them alone to reverse a core update drop.
- Track results over months, and expect that some changes may only show after a later core update.

Common mistakes
- Searching for a penalty that isn't there. A core update drop is not a manual action and will not appear in the Manual Actions report.
- Taking "no fix" literally. It means no quick fix, not no improvement.
- Making drastic sitewide changes in the first days of a rollout. Rankings often keep moving until the rollout ends.
- Ignoring the winners. The pages that gained usually show what Google now considers more helpful.
- Trusting nicknames as descriptions. "Brackets" tells you nothing about what the update targeted.
