The Challenge
18,000 Products. 10 Websites. Generic Supplier Copy Everywhere.
The client operates over 10 e-commerce websites, collectively listing more than 18,000 product SKUs. Every one of those product descriptions was sourced directly from the supplier — the same generic, often poorly written copy that appears on every other retailer’s website selling the same products.
This created two significant problems. First, from an SEO perspective, duplicate content across the web is penalised by search engines. The client’s product pages were competing against hundreds of other sites using the exact same descriptions, making it virtually impossible to rank well. Second, the generic supplier copy didn’t reflect the client’s brand voice, didn’t address their specific customer base, and often lacked the detail and persuasion needed to convert visitors into buyers.
Rewriting 18,000 product descriptions manually would be an enormous undertaking — potentially months of full-time work by a content team. And it’s not a one-off task: new products are added regularly, and descriptions need ongoing updates to stay competitive. The sheer scale made manual content creation completely impractical.

The Solution
AI-Driven Content Transformation at Scale
Black Lantern built an automated content engine that reads the existing supplier product data, processes it through AI with carefully crafted prompts, and generates new descriptions that are optimised for both search engines and the client’s target audience.
The system works by ingesting the current product data — titles, descriptions, specifications, categories, and attributes. It then applies a predefined AI prompt that has been carefully tuned to the client’s brand voice, SEO requirements, and specific content guidelines. The AI rewrites each description to be unique, engaging, keyword-rich, and tailored to the way the client’s customers search for and evaluate products.
The rewritten content is then dynamically pushed to the relevant website, updating the product pages without any manual intervention. The system is designed to handle the full catalogue across all 10+ websites, processing thousands of SKUs efficiently and consistently.

The Results
Months of Work, Completed in Hours
Before
- 18,000+ products with identical supplier copy
- Duplicate content hurting SEO rankings
- Generic descriptions with no brand voice
- Manual rewriting would take months
- New products added with default copy
- Inconsistent quality across 10+ sites
After
- Unique, optimised descriptions for every SKU
- SEO-friendly content improving rankings
- Consistent brand voice across all products
- Full catalogue processed in hours
- New products auto-processed on addition
- Uniform quality across all websites
What would have been an ongoing, resource-intensive content project was completed in a couple of hours. Every product across all 10+ websites now has a unique, SEO-optimised description that reflects the client’s brand and speaks directly to their customers. The system continues to process new products automatically as they’re added to the catalogue, ensuring the content never falls behind.
The client has already seen improvements in search engine visibility for product pages that previously struggled to rank due to duplicate supplier content. The AI-generated descriptions are more detailed, more persuasive, and better aligned with how their customers actually search — resulting in improved engagement and conversion rates across their entire product range.
Because the prompts are fully configurable, the client can refine their content strategy at any time. Seasonal adjustments, keyword pivots, or changes in brand direction can be applied across all 18,000+ products simultaneously — something that would be impossible to achieve at this scale with manual content writing.
