Duplicate and Thin Content Pages
Ever since the introduction of the Google Panda Penalty into their algorithm (see Josh Bachynski's website for the full list of factors), duplicate content and pages with little to no unique content have been penalised heavily within Google.
Entire websites have been filtered out overnight with a complete drop in Google traffic from this problem alone.
On the Amrita Nutrition website there are countless examples of this happening, from brand pages that have direct copies of the manufacturers bio (such as in the image above), to pages with a title and a list of products and nothing else on the entire page.
An example of the thin content pages is for the keywords around "Bone supplements", where the Amrita page has a title and a list of products, and ranks on page 2 for "buy bone health supplements" which is what their page title is optimised for.
If you compare this page to the simply supplements page which ranks in #4, you can see that they have much more content around the topic on the page:
Suggestions to fix:- Calculate the most profitable / easy to rank keywords and fully optimise their landing pages with unique, relevant content.
- Add internal links to these high priority pages from within the main content of pages with inbound links.
- Build inbound links to these pages through link building campaigns.
