We have a lot of "Long URL" errors in moz, and our URLs have no helpful format to them. For example, our blog URLs currently have a date and the title so they end up looking like this: blog/year/month/day/long title that never ends.
If I were to setup a new URL structure using MOZ best practices, can I just make the change going forward and redirect a few high trafficked links to this new structure? Or do I really need to make the change for the website (specifically blog) as a whole to see a positive impact? I know this means there may be an initial drop in traffic which I'd like to avoid.
