One of the things with this update from Google that is not mentioned much if at all, is that the adverse
affects will be felt by the high domain authority sites with crappy content.
I'm looking at you Yahoo News & CNN.
If you are publishing quality content that has some similarities to the rest of your sites content then your rankings will improve.
As ranking of the sites relying on their domain authority begin to sink because of their lack of "helpful content", your rankings will improve.
Google’s new helpful content update
specifically targets “content that seems to have been primarily created for ranking well in search engines rather than to help or inform people.”
The purpose of this algorithm update is to help searchers find “high-quality content,” Google told us.
Google wants to reward better and more useful content that was written for humans and to help users.
Content written for the purpose of ranking in search engines – what you might call “search
engine-first content” or “SEO content,” has been frequently written about lately and discussed across social media.
In short, searchers are getting frustrated when they land on unhelpful webpages that rank well in search because they were designed to rank well.
