We run an e-commerce site selling wholesale and retail technical hardware out of Düsseldorf. Our catalog has around 1,800 products and most of them previously only had the technical spec sheet directly from the manufacturer. To boost their organic visibility we set up an SEO text generator last month, auto-generated descriptions for 350 products in the first phase, and published them.
On the surface the descriptions are grammatically solid paragraphs packed with relevant keywords. However, even after 6 weeks, we havent seen any noticeable rank increases on Google nor any movement in organic clicks. In fact bounce rates went up on some pages. Im starting to suspect the content is just fluff that provides zero value to the user.
How can we measure the actual ranking impact of auto-generated texts? Which product categories should definitely be written by hand, and which ones can stick with automated templates? I'm looking for a clear vetting framework to make this distinction.
