Welcome to the Q&A Forum

I have a client site that launched last June and rebranded this February 2012 as http://49thshelf.com The search traffic since Feb has been steadily declining despite some great campaigns to drive traffic and engagement. April down 40% vs. Mar May down 37% Jun down 51% Jul 16% We have a couple of challenges. The site is the only collection of Canadian-authored titles. It's like an Amazon of only Canadian titles. But it's not ecommerce, we direct traffic to other vendors like Amazon or the publisher to buy. We have 40,000 unique products on the site and the descriptions are primarily supplied by the publishers, which means it's the same content on the publisher site as Goodreads, Amazon and anyone else they share data with. Those big players like Amazon and Goodreads use user generated content to alter the descriptions but we don't have that level of activity on the site. Members create reading lists, the editorial staff curate collections on the homepage and there are interviews, blog posts and guest posts. No black hat SEO, no bad links that I can see. Great organic membership growth and interactions. Good activity from social media sites to the site. Good, trusted links from news sites and legit blogs. I don't know what to do to improve the organic traffic. July is the first month that we haven't seen 40-50% drops. Any advice is welcome, thank you!
