Great feedback, guys. Thank you.
The articles are mostly news related so there's not a whole lot of reason to keep them, however we tend to have people dig fairly deep into topics such as cars or watches. This content tends to be timeless.
REASON FOR THE INITIAL QUESTION
We have however also seemed to hit a wall with organic traffic. We did think this was perhaps because of having too many articles on the site but we're not too sure.
We get 10k organic referrals per day, everyday. It fluctuates maybe +-100 but it's like it's we're stuck at a ceiling.... hence the reason we're looking at changing link structure to maybe help move this imaginary log jam.
Some of our in-house practices
Old evergreen articles are always being update
URLs updated so date stamp is more recent - then 301 redirect put in place
Major newspapers and high authority websites regularly linking to use for 'expert advice'
We seem to be doing everything by the book but something's stopping our growth.... maybe changing all the URLs and the structure may not help.
