Google’s September 2026 spam update is complete: what Hong Kong SMEs should check

According to the Google Search Status Dashboard, the September 2026 spam update began on 24 September 2026, applies globally and to all languages, and finished rolling out on 8 October 2026. The roughly two-week window matches Google’s note that rollout may take up to two weeks. A spam update is a notable improvement to Google’s automated spam-detection systems—not the same thing as every core ranking update—and the dashboard notes for this rollout did not name a single targeted tactic.

Why this matters for Hong Kong SMEs

If your site mainly serves Hong Kong customers in Cantonese or Traditional Chinese, the update still applies: Google stated coverage for all languages. The useful response is not chasing short swings in third-party rank trackers. Use Search Console to compare performance before and after the window, then review Google’s published spam policies for clear violations on your own site.

Spam update versus Manual Action

Google Search Central’s spam-updates documentation says sites that change after a spam update should review the spam policies. Violating sites may rank lower or not appear at all. Fixing problems may help once automated systems learn—over a period of months—that the site complies. A Manual Action is separate: it follows human review and appears in Search Console’s Manual actions report and message centre. Check both; a traffic dip alone does not prove the spam update caused it.

Compare the date window in Search Console

• Open the Search results Performance report on a daily view from early September through mid-October 2026.
• Use about one week before 24 September as a baseline, then compare with about one week after 8 October for clicks, impressions and average CTR.
• If a decline started before 24 September, it may predate this spam update—also check seasonality, ads, technical errors and indexing.
• Open the Manual actions report. If a human action exists, fix every affected page as the report describes before requesting a review.

Policy areas SMEs should self-check first

Google’s spam policies list many practices. For typical Hong Kong SME sites, start with these (the official page remains the full list):

• Scaled content abuse: many pages generated mainly to manipulate rankings, including bulk AI pages that add little value for readers.
• Scraping: copying other sites’ content with only light edits and little original value.
• Thin affiliation: product copy lifted from merchants without original reviews, tests or useful comparisons.
• Keyword stuffing and hidden text or links: wording or elements written for engines rather than customers.
• Hacked content: injected spam pages, sneaky redirects or hidden links—also check the Security issues report.
• Link spam: buying or selling links for ranking, excessive reciprocal schemes, and similar patterns. For link-spam-focused updates, Google notes that ranking benefit from spammy links is not something you can later regain.

If you find problems

• Stop producing, and remove or substantially rewrite, low-value, duplicated, scraped or search-only bulk pages.
• Keep and strengthen pages that help customers decide: services, pricing where appropriate, process, location, contact details and clear explanations.
• Harden security: update CMS and plugins; look for unexpected new pages and redirects.
• For a Manual Action, fix everything first, then request review in Search Console. Automated spam updates have no one-click restore; systems reassess over time.
• Avoid panic mass-deletes or overnight rewrites done only to “force recovery.” Fix policy issues, then watch Search Console for weeks to months.

What not to do

Do not treat a brief third-party rank-tracker wobble during rollout as proof of a penalty—coverage of this update also noted that some trackers showed movements that did not match what people saw in Search. Do not promise that fixes will restore previous rankings: Google only says compliance may help as systems learn over months, and outcomes vary by site.

Short checklist

• Record the window: started 2026-09-24, completed 2026-10-08.
• Compare Search Console Performance for a week before and a week after.
• Confirm the Manual actions report is clear.
• Review official spam policies—especially scaled content, scraping, thin affiliation and hacked content.
• After fixes, keep monitoring; recovery may take months, not a day.
