This algo change does nothing to do with scraped content since i view a lot of scraped content in top result now, at least for my niche. And not a single element to add value for users.
Different types of sites has been affected, forums, blogs, e-commerce, sites with original or scraped content, small and old sites, affiliate or non-affiliate links, sites with a strong backlink portofolio gained by years.
Searching to see what sites are displayed now in SERPS shows me no improvement, even lower quality than before.
A possible cause can be the aggressive positioning of ads, users are likely to click an ad immediately they go on a page. But this can be weird since Adsense team recommends to put ads top of the article, do not hide ads in right sidebar, even e-mails like "we have noticed your website does not display ads on some pages with potential and we recommend to put ads to increase your revenue .." Or maybe they want to shut down Adsense? LoL
This update is still a mystery for me, since the new results doesn't bring quality.
