Welcome to the Q&A Forum

Google hates duplicate near duplicate content so the first thing I would question is whether your new content falls into the category, if so will devalue your site - hence the traffic drop!

Thats a good point Adam. Thanks for your assistance.

Thanks Doug. That is really helpful.

Thanks for your help Chris

Yep. We did that. Thanks for the suggestion.

Thanks,

Thanks for your help Chris
