In the age of instant content creation, many marketers are tempted to rely on AI to churn out articles at scale. But does that translate into real search visibility and traffic? A 16‑month experiment conducted by SE Ranking and a research team aimed to answer that question head‑on. The study involved 20 brand‑new domains, each with zero backlinks, no domain authority, and no prior search history. The content on these sites was generated entirely by AI, with no human editing or enhancement. The results? A sobering reminder that quantity does not equal quality in the world of search engines.
The Experiment Design
The goal was straightforward: determine how far AI‑generated content could go in Google Search when starting from scratch. The researchers wanted to know three things:
- How quickly would the AI articles be indexed?
- Could they rank for relevant queries?
- Most importantly, would they attract any organic traffic?
To keep the test as controlled as possible, the team purchased 20 new domains, each chosen to represent a distinct niche. None of the domains had any backlinks, domain authority, brand recognition, or search history. The niches ranged from Arts & Entertainment to Vehicles & Boats, covering a broad spectrum of interests and industries. The list of niches is reproduced below for reference:
- Arts & Entertainment
- Business & Services
- Community & Society
- Computers & Technology
- Ecommerce & Shopping
- Finance & Accounting
- Food & Drink
- Games & Accessories
- Health & Medicine
- Industry & Engineering
- Hobbies & Interests
- Home & Garden
- Jobs & Career
- Law & Government
- Lifestyle & Well‑being
- Pets & Animals
- Science & Education
- Sports & Fitness
- Travel & Tourism
- Vehicles & Boats
For each domain, the team generated dozens of AI‑written articles covering a range of sub‑topics within the niche. No human editing, rewriting, or optimization was performed. The content was then published, and the researchers monitored indexing, ranking positions, and organic traffic over the course of 16 months.
Key Findings
While the AI content was indexed relatively quickly—most pages appeared in Google’s index within 2–3 weeks—the results in terms of rankings and traffic were underwhelming:
- Indexing speed: 85% of the published pages were indexed within the first month.
- Ranking performance: Only 3% of the pages managed to appear in the top 100 search results for any query, and none cracked the coveted top 10.
- Organic traffic: Across all domains, the total organic visits over the 16‑month period averaged just 12 per month
