Google October 2023 Core and Spam Updates Explained

What happened in October 2023

Google’s Google Search Status Dashboard lists the October 2023 spam update as starting on 4 October 2023 and finishing on 19 October, about 15 and a half days. The October 2023 core update started a day later, on 5 October, and finished on 18 October. For almost two weeks, both were rolling out at the same time. The dashboard also shows a separate general “ranking is experiencing an ongoing issue” entry that began on 5 October, so that month was a busy one for search volatility.

That overlap is the most important practical fact. If a site lost or gained visibility between 4 and 19 October 2023, there is no clean way to say which update did it. The sensible approach is to treat the two as one event and investigate the affected pages for both kinds of problems: spam-policy violations and general quality.

The October 2023 spam update: what Google said

Google announced the spam update on 4 October through its Search Central channels. As reported at the time by Search Engine Roundtable, Google said the update applies globally and improves coverage in many languages, and it specifically named Turkish, Vietnamese, Indonesian, Hindi and Chinese. Google’s Search Liaison also said that English-language sites were affected to some degree, since the update involves all languages.

The types of spam Google said it was aiming at were:

• Cloaking: showing search engines different content from what visitors see.
• Hacked content: pages or spam injected into a site without the owner’s permission.
• Auto-generated content: pages produced mainly to manipulate rankings rather than help people.
• Scraped content: material copied from elsewhere that adds little original value.

Google also said it would refresh the systems periodically and that recovery from a spam-related drop can take a long time. Google did not publish how many queries or sites were affected, and it does not share the internal detail of how its spam systems work beyond what is in Google’s spam policies.

The October 2023 core update: what Google said

Core updates are broad changes. Google’s core updates guidance says Google makes these changes several times a year, that they do not target specific sites or pages, and that most sites do not need to take action. Google did not publish a list of what changed in October. What we do know is that the November 2023 core update was described by Google as improving “a different core system than last month,” which implies that the October update touched a different part of the ranking systems. That is an inference from Google’s own wording, not a detailed explanation, and Google has not said which systems were involved.

Helpful content context at the time

In October 2023 the helpful content system was still a separate system. It had been introduced in 2022, and an update to it had rolled out in September 2023, just weeks before these updates. According to Google’s guide to its ranking systems, the helpful content system became part of the core ranking systems in March 2024 and is now listed as retired. So when people say a site was hit by the helpful content update in autumn 2023, they usually mean the September update, the October core update, or the November core update. Often it is a mix, and the three are impossible to fully separate.

The guidance underneath all of it has stayed consistent. Google’s guidance on creating helpful, people-first content describes content made primarily for people, with original information, first-hand experience and a clear purpose, as opposed to content made primarily to attract search traffic. If your site was unaffected, that is a sign your approach was working. If it was hit, that same page is your best self-assessment tool.

Who was most likely affected

Google has not published a list of affected site types, so we will not pretend to know. Based on what the spam update was designed to catch, the sites with the most reason to worry were:

• Sites with auto-generated or heavily scraped pages, including affiliate and directory sites built from copied feeds.
• WordPress sites that had been hacked, where injected pages or hidden links were serving spam without the owner knowing.
• Sites using cloaking or sneaky redirects.
• Multilingual or foreign-language sites, because of the explicit language expansion.

For core update effects, the picture is broader and less predictable. Google says a drop does not necessarily mean content is bad, only that other content may now fit what searchers want better.

What to do if you saw a change in October 2023

1. Confirm the dates. Compare your Search Console data from the weeks before and after, using the full windows above. Our timeline of Google updates from 2023 to 2026 helps you place any date quickly.
2. Check for hacking. Search Console’s security issues and manual actions reports are the first place to look. Scan the site for unfamiliar pages, injected links and odd redirects. A WordPress site with outdated plugins is the usual suspect, and our WordPress services include cleanup and hardening.
3. Test for cloaking by accident. Use the URL Inspection tool to see what Googlebot sees, and compare it with what a visitor sees. Differences caused by a caching or security plugin are more common than deliberate cloaking.
4. Review auto-generated or scraped sections. If you have bulk pages that add no original value, improve, consolidate or remove them. Google recommends improving content first and deleting as a last resort.
5. Audit for technical problems. A technical SEO audit checks indexing, redirects, speed and crawl issues that can look like an algorithm hit.
6. Strengthen the pages that matter. Add real experience, clearer authorship and local detail. Our content SEO service focuses on that kind of improvement rather than volume.

What not to do

• Do not file a reconsideration request unless Search Console shows a manual action. Algorithmic spam demotions do not have a request form.
• Do not disavow links in a panic. A spam update is not evidence of a link problem, and disavowing without a clear reason is rarely the fix.
• Do not replace human-written pages with mass AI output. That is the kind of auto-generated content the update language targets when it exists mainly to rank.
• Do not make big edits while the rollout is still in progress. Wait for completion, then analyze.

Lessons that still apply

Looking back, the October 2023 updates were an early signal of a direction Google kept pushing: more attention to spam at scale, and more weight on content made for people. The spam policies were later expanded in March 2024, covered in our post on the Google updates blog and in our dedicated article on the March 2024 core and spam update. If you run a small Oregon business, the takeaway is not to chase each update. Keep the site clean and secure, write for customers, and fix problems when you find them. Our November 2023 core and reviews updates post continues the story.
