Google’s September Spam Update: A Warning for Construction Websites
Google began rolling out its latest spam update on 24 September 2026. It applies globally, across all languages, and could take up to two weeks to complete.
Google has not said that it targets construction websites specifically. But the update should concern any contractor, consultant or product supplier relying on large volumes of generic SEO content.
Common risks on construction websites
Construction websites commonly contain:
- Near-identical location pages
- Recycled manufacturer copy
- Thin service pages
- Generic AI-written blogs
- Articles targeting keywords unrelated to commercial priorities
None of these formats is automatically spam. The risk is publishing pages primarily to capture search traffic without providing original, useful information.
The location-page problem
Creating a separate page for every town is still a common construction SEO tactic.
The problem is not the number of pages. It is whether they contain anything genuinely local.
Changing “Manchester” to “Stockport” does not create a useful new page. Strong location content should include relevant projects, service coverage, logistical considerations, local experience and evidence that the company operates in that area.
If a page could target another town after changing one word, it is probably too thin.
AI content is not automatically the issue
Google does not ban AI-generated content.
Its spam policies focus on scaled content created primarily to manipulate rankings—regardless of whether it was written by AI or a person.
That distinction matters.
An AI-assisted article reviewed by an experienced engineer or contractor can be useful. Fifty generic articles that repeat existing search results are unlikely to build meaningful authority.
Construction businesses should use their strongest advantage: first-hand experience. That means publishing:
- Detailed project case studies
- Original site photography
- Technical explanations
- Cost and programme considerations
- Problems encountered during delivery
- Material and system comparisons
- Measurable project outcomes
This is harder to reproduce and considerably more useful to potential clients.
Do not make reactive changes
The update is still rolling out. Short-term ranking movement does not prove that a website has been affected.
Before rewriting or deleting anything:
- Record current Search Console performance.
- Separate service, location, case-study and blog pages.
- Identify which page groups have lost impressions or clicks.
- Check indexing and technical issues.
- Review any large groups of duplicated or lightly rewritten pages.
- Wait for a sustained pattern before making major changes.
Google advises website owners to avoid radical changes in response to ordinary ranking fluctuations.
What construction companies should review
The immediate priority is not producing more content. It is assessing whether existing content demonstrates genuine capability. Review:
- Location pages with little local evidence
- Services without supporting projects
- Articles that receive traffic but no enquiries
- Copied supplier or manufacturer descriptions
- AI content published without technical input
- Multiple pages targeting slight variations of the same query
Weak pages may need improving, consolidating or removing from Google’s index. That decision should be made page by page—not through a blanket content purge.
The practical lesson
Publishing more pages is not the same as building more authority.
Google’s direction is clear: websites should provide original, useful information rather than manufacture pages around every possible keyword.
For construction businesses, the answer is already available in completed projects, technical knowledge and delivery experience.
The job of construction SEO is to turn that experience into credible evidence—and make sure the right clients can find it.
