Success cases about PIM-enrichment with SEO-benefits?

[Inevo]

Hello

Does anybody know about any ecommerce sites that have done PIM-enrichment projects with great success, resulting in significant increase in organic traffic and rankings?

Our agency is doing a presentation about leveraging better and more product information for long-tail SEO, and we'd like some success cases to point to.

Thanks
