Many large websites rely on machine generated and mashable content to differentiate their landing pages. And if done properly, I suppose it can present well to site visitors. But what about Google. How risky is this post Panda for sites, large or small?
I've been surprised (in the travel niche) by how many sites are getting good/improved results post-panda by simply having large numbers of pages of mashed date - weather, driving distances, maps etc for each location, along with adsense and affiliate links - with little or no UGC on the pages.
They do all seem to have lots of data on each page, though - I've not seen any with very low amounts of content that are rating highly, to the point that I suspect that the actual amount of content on a page, regardless of its source, is now a much more relevant ranking factor than it used to be.
I'm guessing these sites will largely get devalued in due course - but of course that's just a guess...
