Hello Tompt,
thank for your answer.
No, duplicate content is not what I mean.
It's the point that these tag oder archive pages, which only contains of list of internal links and content snippels (like: http://www.seomoz.org/blog/popular/past-30-days) could be seen as low quality content, because its in fact just a mix of differant post snippets und linking titles and not a real article or one-piece of content.
1. Question: Do you think oder have data, if tag/archives sites like this (just internal links with little content snippets) are "low quality" in googles eyes, especialy after the Panda Update?
2. Question: If so, would it be a problem to have a great number of these pages in the index (700)? Especialy in view of the Panda Update? Because in fact I have more tag/archive pages than realy article pages (500) in the index.
If it is not a problem, it could stay as it is. If it could become a problem, when Panda rolls out in Germany - I may should change something or get these pages out of the index.
I realy hope, you understand what I mean.
Thank you.
