Ok here is just one example of what we are seeing.
We follow video games, pretty bigname in our industry. So in this example we have a page which we wrote a review of one of the most popular games out today. This document is 6 years old. We all have played this game thousands of hours so we know what we are talking about. Anyhow this review also had a couple tutorials we wrote to help newbies to the game with specific things.
Those tutorials have been updated over the years with each expansion of the game. They are real step by step tutorials with screens and videos. Anyhow overtime these guides built links all by themselves due to usefulness, infact the actual game company which is PR 7 alexa 2000ish links to these guides and constantly points them out to the fanbase of millions in the forums.
So for a handful of these guides we ranked 1-3 over the years for various terms. Good traffic, less then 10% bounce rate, just really good stuff. Well we are now result 25ish for all terms related to this game. Very basic SEO, basically what Google advocates. What has replaced us you may ask? Well that's the fun part.
Result 1 Wikipedia with a general about for the game.
Result 2 A Ehow article from 4 years ago with absolutely no relevant content to the query.
Result 3 A hubpages article again that is totally out of date and useless to the querytype.
Result 4-24 I dont want to even bother typing as it is just about borderline spam.
So I guess our page that was written by people playing the actual game for 5-6 years, updating the article constantly to keep it useful to the games changes and linked to by thousands of game sites and forums and social platforms and the game creator itself has now been deemed useless!
I know you are reading this Google, what in the world are you doing? How does the above example show an improvement in your results? Do you define our article as low quality despite those natural signals and find wiki, ehow and hubpages better despite them being completely unrelated to the query type and 99% less related natural signal strengths?
This is one of thousands of examples I can post. What in the world did you push yesterday? Added note, we still are 1-3 in BingHoo.
