Domain stuck at end of SERPs for main keywords

[poolhall]

I'm trying to figure out why a site has been stuck at the end of the SERPs for almost a year.  On August 5, 2011 the site went from getting 1,400 visits per day from Google down to 20 visits a day from Google.  For the keywords it ranked on the first page for it went to the last page in the SERPs.  With Panda and Penguin, it probably wouldn't rank like it used to, but it seems to be stuck in some sort of domain wide penalty that pins it to the end of the SERPs.  Even when completely new content  will show up at the end of the SERPs, which makes me think it's stuck in some sort of filter.  Thanks in advance for any constructive ideas.

Although there is less but one thing that you might be missing is the removal of dead links or low quality links that are pointing to your site…

Is there any network of sites that are pointing back to your website? If yes try and remove the links from network sites or site-wide links that are pointing back to you.

I think removal of bad links is going to help you get well in search engines.

On the analytics side, the only real data is the complete drop in Google organic visits, everything else looks normal and consistent with other sites that perform fine.

On the webmaster side, there is no data or information which would indicate what the problem is.  I did do a reconsideration request, but the message was that there was no manual spam penalty, only algorithmic ranking.  There are no, and have been no, messages from Google that anything is wrong.

I have tried changing titles, descriptions, sitemaps, page structure, page content, outbound links, inbound links, adding unique content, removing duplicate content, deindexing weak content, deindexing all content, reindexing all content, fixing html, validating html, breaking pages, fixing pages I broke.  Nothing seems to change the results.

The filter seems to work on searches that have some volume, as it will still rank for an occasional obscure long tail keyword phrase for a while and then fade from that search as well.

In the general analysis of your website the website seems good enough and properly optimized. The links seems to be relevant to the niche (in a quick overview) although the distribution of links pointing to internal pages is quite low but this should not cause this problem.

It’s difficult to solve this problem from this side of the corner but access to analytics and webmaster tool might help... take a deeper look in to analytics and webmaster tool and you might figure out where the exact problem is!

As this case is very interesting to me let me know if you need any help from me and i would be happy to assist you!
