Google Blog
Is it a tacit admission of defeat when Google says it’s going to stop the spam from content farms, but then offers an extension to Google Chrome which lets users block content farms in their search results?
If people have to block content spam manually, that means Google can’t (yet) do it algorithmically. Of course, the “blocked sites” data is sent from Chrome back to Google so they can, hopefully, find a way to tweak their algo to automatically stop content farms from spamming their search results.
As article spinning gets more and more subtle, the line between genuine content and content farms is becoming more and more blurred. How Google can hope to do more to distinguish between the two types of “content”, even with user-input, is hard to see.
When you take into account LSI, content length, site quality, PageRank, domain age, authority, trust, keyword density, original v duplicate content, bounce rates, internal link patterns and all the other variables that Google measures yet they write on their blog, “people are asking for even stronger action on content farms and sites that consist primarily of spammy or low-quality content“, I don’t see what more they can do.
