Google's September 2026 Spam Update Is Done: What Should B2B Sites Check?

Did the September 2026 spam update hit your B2B site?

Google released the September 2026 spam update on September 24 and said the rollout was complete as of October 8, 2026. If your organic traffic dropped in that window, check whether the drop lines up with those dates, then compare your site against Google's spam policies before changing anything else.

I watch these updates closely because most of the people I work with run B2B and SaaS sites that depend on search for pipeline. A spam update is a different animal from a core update. It is not about who has the most helpful page. It is about whether a site broke a written rule.

That difference matters, because the right response is also different. You do not rewrite your best pages after a spam update. You audit for the specific practices Google names, and you leave good pages alone.

What did Google actually announce?

Google posted the update on its Search Status Dashboard on September 24, 2026. The note said the update applies globally and to all languages, and that the rollout may take up to two weeks. A second note on October 8 said the rollout was complete. Google did not describe a specific target beyond that.

That is the whole announcement. I want to be clear about it, because I have already seen posts claiming the update targeted AI content, or link networks, or a specific niche. The dashboard entry does not say any of that. Anyone telling you exactly what this update hunted is guessing.

It is also the second spam update in a short stretch. The same dashboard lists an August 2026 spam update that started on August 18. Two in close succession is a good reason to do a calm policy audit now instead of waiting for a third.

Why does a spam update matter for a B2B or SaaS site?

A spam update matters for B2B sites because organic search often feeds the top of the funnel. Google's spam documentation says affected sites may only see improvement after its automated systems learn, over a period of months, that the site complies with its policies. That is a long time to run without a steady lead source.

Think about what search feeds in a typical SaaS go-to-market motion. Comparison pages catch buyers who are shortlisting. Integration pages catch buyers who already use a tool like HubSpot or Salesforce. Glossary and how-to pages feed retargeting audiences and newsletter signups. When one of those clusters loses visibility, the drop shows up weeks later as thinner pipeline in the CRM.

So the question for a founder or marketing lead is not "did my site get hit?" It is "if it did, which revenue path depended on it?" Answer that, and you know how urgent the audit is.

Which spam policies should B2B teams read first?

Start with scaled content abuse, expired domain abuse, the site reputation policy, and link spam. Google's spam policies page lists sixteen named practices plus a catch-all section. These four are the ones I see B2B and SaaS teams drift into by accident while chasing traffic, often without anyone deciding to cut a corner.

Google defines scaled content abuse as many pages generated for the primary purpose of manipulating search rankings. Notice what that sentence does not say. It does not say AI is banned. It does not set a page count. The test is purpose. A template that creates five hundred city pages with nothing different on them except the city name fails that test, no matter who or what wrote them.

Expired domain abuse is buying an expired domain and repurposing it mainly to manipulate rankings. I still see growth playbooks that suggest buying an old domain with backlinks and redirecting it to a product site. Treat that as a risk, not a hack.

The site reputation policy covers third-party content published on a host site to borrow that host's standing. If you rent out a subdirectory on your SaaS blog for sponsored coupon pages or unrelated product reviews, read that section of Google's documentation carefully. I wrote more about how that policy evolved in my post on the Google site reputation policy update.

How do you tell a spam update drop from a normal dip?

Compare the timing of the drop with the update window, check whether it hit one page type or the whole site, and look in Google Search Console for a manual action. A drop that starts inside the window and clusters around one template is a strong signal. A gradual slide is usually something else.

Here is the order I use. First, open the Performance report in Google Search Console and set the date range to cover August through today. Look for a step change, not a slow curve. Second, filter by page and group the losses by template: blog posts, comparison pages, programmatic pages, integration pages. Third, open the Manual actions report. A manual action is a human review, and it comes with its own explanation, which is far more useful than guessing.

Then cross-check against your own changes. Did you migrate the site, change URL structure, or ship a new template in September? A broken canonical tag or a botched redirect can look exactly like a penalty in a traffic chart. I have seen teams spend a week reading spam policies when the real cause was a Webflow redirect rule pointing to the wrong folder.

What should you do if a page type lost visibility?

If one page type lost visibility, audit that template against the specific policy it most resembles, fix or remove the pages that exist mainly for rankings, and then give it time. Google says recovery happens as its systems learn compliance over months. There is no reconsideration form for algorithmic spam demotions.

For programmatic pages, ask a blunt question about each one: would a buyer be glad this page exists? If the honest answer is no, either add real substance or remove it. Real substance means data, a worked example, or a decision the reader can make from that page alone. Swapping one keyword in a template is not substance. If you built pages from a CMS collection, my programmatic SEO tutorial for Webflow CMS covers how to give each item genuinely different content.

For links, the news is harder. Google's spam update documentation says that when a link spam update neutralizes links, any ranking benefit those links generated is lost and cannot be regained. Cleaning up will not bring that benefit back. The only path is earning links that count.

Do not panic-delete good content. A spam update does not punish thin effort. It acts on specific practices. Deleting a strong case study because traffic fell sitewide only makes things worse.

Does publishing a lot of content put you at risk?

Publishing a lot of content does not break Google's spam policies by itself. The scaled content abuse policy is about pages made primarily to manipulate rankings. Volume is a signal worth watching, but purpose is the test. A large archive of distinct, useful answers is a different thing from a large pile of near-duplicates.

I have a personal stake in this one. I have published more than 1,000 articles on AI answer engines, schema, and E-E-A-T, and I use automation to research and draft. So I ask myself the same question I ask clients. Does each article answer a different reader problem, with a different decision at the end? If two posts would leave a reader with the same answer, one of them should not exist.

That is why I run a near-duplicate check before I publish anything. It compares every new topic against the full archive and flags overlaps. It is not a magic shield. It is a habit that keeps the purpose of each page honest, which is exactly what the policy asks for.

What should you leave alone after this update?

Leave your strongest pages, your schema markup, your internal links, and your publishing cadence alone unless you find a specific policy problem. Spam updates act on spam practices. Changing unrelated things at the same time makes it impossible to tell what helped, and it can create new problems while you wait.

The most common mistake I see after any Google update is the everything-at-once rewrite. A team loses traffic, then changes titles, deletes posts, rebuilds navigation, and swaps their SEO plugin in the same week. Two months later nobody knows which change mattered.

Make one change per page type, log the date, and watch that page type in Search Console. Treat it like an experiment in your GTM reporting. If you track pipeline sources in HubSpot, add a note on the date so the sales team knows why inbound volume moved.

What should you do next?

This week, confirm whether any traffic drop lines up with September 24 to October 8, check the Manual actions report, and read the four spam policies most relevant to B2B sites. If nothing lines up, keep publishing useful work. If something does, audit one template at a time and give it months.

Bookmark the Google Search Status Dashboard and check it whenever traffic moves. It is the primary source for every ranking update, and it will save you from reacting to rumors on social media. Pair it with a simple log of your own site changes, and most traffic mysteries solve themselves.
