I also have noticed increased power of older domains/urls in caffeine. Can't tell if it's due to age of backlinks, or age of the urls. Any thoughts?
Most of my sites suffered a huge Google traffic loss one month ago. But the only two sites that have not been affected are both older than 8 years old. Additionally, looking at the pages that Googlebot comes to visit, I see them trying to read pages that do not exist since 2008 and have since been 301-ed to new URLs (on the same site)
