So here are some facts,I have many sites some are high ranked some are poor ranked in Google due to seo that I do,now here is the latest thing i noticed my high ranked sites are now no where to be seen in the top 10 but my sites with no seo are in the top 10 not only that there are some blogs out there auto blogs that blatantly steal my content with a small link on the post back to my site and they out rank my site,they seem to be on first page with stolen content and mine are gone lol its laughable,maybe its time to look into yahoo and bing more Google is a disaster.
I think they know what they are doing but are just doing some experimenting right now or something - who knows!
Too many scammers and people who think putting up content means that they will constantly keep their rank. Google likes fresh, relevant content. If you keep your site with the same content for months and months, your site will be nowhere to be found.
Great to experiment in a lab or in places that does not affect others but not when it affects peoples lives hey maybe it will correct itself i see many posts about this latest change they made even affecting big companies who are making people jobless because of this not good in my opinion.especially when it affects sites that are legit and do everything by the book.
Remember that Google looks at things with a very wide angle view - when they roll out changes like this they measure the affect across a massive dataset with a whole load of different ways of judging the impact - positive or negative. Undoubtedly with an update this size there are going to be many places that are affected negatively, but in this case, I think the overall impact (from a user-experience POV) has been positive. They'll probably then work to weed out the negative areas with further, smaller updates. So don't give up hope yet - just keep trying to persuade Google you're full of good, high quality content.
