I have a website which targets the UK market with a .co.uk domain.
The site was setup in November 2009 and has always done well in the UK rankings. In the past 3 months the sites rankings grew naturally and I could literally publish a page and it be on the first page of Google with no link building what so ever.
and then this happened - [i51.tinypic.com
Whats strange is this doesnt seem to have affected all pages/keywords with a handful of them hanging on to their #1 positions. It's worth noting the keywords I target are usually of 3 or 4 words in length.
Also the October update people are talking of had no impact on the site at all around then.
Each of my pages feature-
100% unique content
Embeded video which is part of the videositemap
Links to relevant external sites
Keyword density between 2%-4%
LSI keywords included
Title tags are written like KEYWORD - Title, eg BLUE WIDGETS - What You Need To Know
I have looked through webmaster tools and there are 2 errors, both of which have been part of the site for a long time.
The first is that I use googlevideositemap.com plugin to generate the video sitemap. This puts a 301 redirect into the sitemap which then pushes people to the page the actual video is on.
The second is I have a plugin that adds pages of comments, so each comment has its own page which causes duplicate title/meta tags.
Other than that, webmastertools looks perfect but both of those have been in webmastertools for a while so I doubt they have made an impact.
So im scratching my head a little bit, I had thought the site had grown to become an authority in its niche as it was climbing rankings and I could literally be on the first page for nearly any term I wanted in my niche just by publishing a page.
I was wondering if anyone would be kind enough to share some advice or perhaps share similar experiences throughout the december period.
Thank you kindly for your time.
