My understanding is that, if content is old & is continuing to get good, varied links, it is treated as 'evergreen'.
In my experience, Evergreen is preferred to fresh which is preferred to old and dead. Think about it - if a piece of content is so good people are still talking about it 5 years later, that's surely a good indicator of its quality, right?
That could be why some are experiancing leaps when they update their content (Going from 'dead' to 'fresh') while others like the OP experience drops (Going from 'evergreen' to 'fresh')
Perhaps. Maybe. I dunno. I'm tired. Leave me alone.
