Okay, I thought I was following best practices. In our industry, electronic hardware, we were ranking well for a particular product line (/spacers) but we wanted to do better. We addressed several concerns that Moz found first; duplicate page titles, lack of meta-descriptions and overall lack of targeted keywords. We also took a new approach to add a better structure to our site. Instead of being presented with a list of part numbers we wanted the user to learn more about our products with content. So we added a /products page with content and a product specific page (/spacers) that is almost a definitive buyers guide.
We are attempting to answer the questions that we think our customers find most relevant. Well our customers might find it relevant but Google sure didn't. After our deployment of new content our rankings for targeted keywords in Google fell from 10-15 to 80-95
As an open ended question, could somebody explain to me why our ranks fell off a cliff?
