Hey guys, I've been putting together an ecommerce site with a decent amount of content. I have tier 1 content that will act as essentially landing pages for major keywords. Then I have 1-5 tier 2 articles that are shorter and pointed to the tier 1 articles. It is aggressive because it is just interlinking on-site. No off-site backlinks just yet. I noticed my indexed pages went up to 80 and they have fallen back down to 67. I'm wondering what may have happened for these pages to be de-indexed? The content is all the same / similar topic so do you all think it might be too close to duplicate content? Also, part of my strategy is to syndicate the content from the site onto other outlets like Blogger, Wordpress (free site), and Tumblr. They are automatically syndicated so the duplicate content would be on those sites for sure. Bad idea? Love to hear your thoughts.
