I would suggest being more careful than ever on taking text link ads since the updates.

Sorry to hear you got dinged.  I've seen negative results after major updates in Google and they sometimes pass.  Google often makes modifications to their changes after they see their affect so I hope that happens for you.

In the meantime here are a few thoughts.

1.  Google is supposed to be good at recognizing tags and archives and not counting content it finds in those sections as duplicate content.

2.  Do you ever republish any of your guest posts on your own blog?  If so Google will count that as real duplicate content.

3.  Do you have pages with quotes or blurbs that are also on other domain's websites?

4.  Can you use Google Analytics to identify the pages and the search phrases that you are no longer ranking for?  If so you might you might be able to find similarities which could help to find a root cause.

5.  This may not matter but I personally would try to eliminate things like the lenghty author bio, double comment policy statement (above and below the bio on your site) and the disclaimer you have in the footer (I'd link to a disclaimer page instead).  This last point may not matter but in your case I'd be doing everything I could.

I hope that helps some.

once you've logged in to the webmaster tools, expand Diagnostics in the left column, then click HTML suggestions. Duplicate content issues will show up there, along with suggestions for fixing them.

Thanks.  I did check that and everything there seems to be fine.

I did check that and it was indexing tags and categories.  I've disabled it.

Thanks!

Have you logged into google's webmaster tools? That will show you if there are pages that google things are duplicated.

I've logged in, but I don't see where I can find out if anything is duplicated.  I did find a place to check duplicate meta tags, but nothing else.  Do you know how I could find out from Webmaster tools?

I’m one of the folks who got left in the dust when Google
updated their algorithm.  My search
traffic is down 40% and almost all of my biggest keywords disappeared off the
first page.  One phrase went from #7 to
#48.

I’m trying to figure out how to address the problem.

I did a check on http://www.virante.com/seo-too.....te-content
and it showed that I have duplicate content.

Here’s the message:

Similarity Check: FAILED

Google indicates that it has "omitted some entries very similar" to
the top 1000 pages on your site. This similarity is a duplicate content penalty
preventing these pages from being considered uniquely valuable in Google's
index.

Then I searched my site on Google:  site:moneyhelpforchristians.com and I went to
the last page entry and saw this message:

In order to show you the most relevant results, we have
omitted some entries very similar to xxx already displayed.  If you like you can repeat the search with
the omitted results included.

Questions:

1.      
 Anyone
know how to find which entries Google is categorizing as duplicates?

2.      
I had a series that ran for a couple of
months.  Each post had the exact same 2-3
sentence intro and the same last sentence though the body was different.  Could that be the problem?

3.      
Any general advice?
