Since the farmer update I have been alarmed about old articles we have on one of our clients sites. Some of these article date way back and are all low quality (useless). Some are even feeds that were imported into the site (using a feed plugin) with just a snippet paragraph and a link back to the original article. This was done way back in 2006.
Now the site has great unique articles. But these old ones we tried to kick start the site with are terrible.
All of them are indexed in google but I am not sure if it is better to 404 delete them, "noindex" them or just leave them be?
As you all know making allot of changes can sometimes trip filters or penalties, which is why I am careful. I am talking about 300 articles here.
a) 404 delete the low quality articles?
b) no index them?
c) leave as-is?
