Can someone please help me understand my sites recent loss of rankings?

My site has been top 3 for 'speed dating' on Google.co.uk since about 2003 and it went to below top 50 for a lot of it's main keywords shortly after 27 Oct 2012. I did a re-submission request and was told there was 'no manual spam action'.

I have a Page Authority of 53, a regular blog http://bit.ly/oKyi88, a KLOUT of 40, user reviews and quality content.

I did discover that another URL I using was set to a 302 instead of a 301 for some reason. I don't necessarily think this was an issue as Google should know which is the trusted URL and therefore which content to list. I removed this redirect completely about 3 weeks ago, but I've seen no improvement.

I'm looking at improving various things, but I'm still not sure why I've been hit and wonder if I'm missing something obvious? Any suggestions greatly appreciated.

Hi Ben,

These are the recent algorithm changes made by Google: http://mozcast.com/events

If your site did not get punished for any of these and you have a natural looking link profile (Anchor text ratio & authoritative qualities) then most likely you are not doing enough link "EARNING" Google+ search #RCS for some ideas : )

Hope this helps!

Thanks for your comments Bryan.

It seems the Exact-Match Domains update on the 27 Sept exactly coincides with my drop. I'm not sure why I would be affected as my domain name is my brand not keyword.

The other update on this day was Panda #20 but I don't what to take from the details of that update. I would say it's more likely Panda #20 and not the EMD update. Do you know what this means? "Abandoning the 3.9.X naming scheme"
