Many thanks for your replies - my feelings are that it's some sort of manual penalty, because ALL of my major keywords have been pushed to page two or below. These are keywords that have been held for years on an 8 year old domain.
The site in question is in the office consumables e-commerce niche and I would have expected it to have been affected by panda, to some degree by now.
All the main competitor sites have pretty much stuck to their old positions. The nature of the business means that none of the competitors sites or mine have brilliant or Shakespearean content.
The only thing I can think that could have caused the review was a sitewide (200,000+ pages) partner/sponsored/ paid link. I have removed this and put in a reinclusion request. But, what worries me is that there are competitors holding top5 positions with paid links coming from this same site.
Also, just noticed - I have our physical address & tel number in the footer of every page - searching for any of these does not bring any page 1 results for my site, but searching for the site/brand name does show us up at position 1.
If it's a manual penalty does anyone know how long would it normally last or how quickly do they get to act on a reinclusion request?
