Like many of you I have been hard at work trying to sort out my site since the Panda update.
The problem I have is I have a large site (120,000 + pages) which I want to condense into about 20,000 pages. After reading everything about panda I think that this will be a good move. Basically we got a bit carried away and created too many thin database driven product pages.
My problem is that now we are now showing 100,000 404's in WMT.
Where we can we are redirecting old pages to the content packed upper sections (all good).
But in some strange instances we are 301 redirecting to a page that returns a 404 or we are 301 redirecting to a page that is then 301 redirecting on to a section head.
Has anybody had a issue with doing a double 301 redirect and is 100,000 404's too many?
We are also adding some excellent informative content. Its been about 3 weeks since we did all these changes but still no movement in the serps. I still have brand new scraper sites well above me.
