Hi, I have 3,700 pages indexed in Google and only 300 are non-supplemental. I have a site map, PR5 homepage, many incoming links and a good internal link structure, unique titles and unique descriptions. If anyone knowledgeable in this area can PM me, I will let you know the URL in question. Thanks
Content needs to be unique and not repeated in your site, you need to have backlinks to those sites (internal linking, and more external linking). Said that, your site should be fine..
If you have unique content and unique meta tags on the pages then try to get quality backlinks for your inner pages. It will help you to remove supplement.
Not true. I have a couple of very related PR7 links (not bought) but still lot of pages are supplemental.
Everybody has said it but Adding content should help. I had to remove a lot of content from a website, due to a new Google TOS, and got Supplementally penalised for being good. The pages were still there but the contents had shrunk. I had to add new content to each of the pages, and had to wait 2 months Such a pain. Rewriting 1000+ pages, and it was a good niche so I didn't want to outsource the content writing. Deep linking sure helps, but LITTLE content is what good don't like. PM me the url.
