I'm doing some research to better understand the process around updating old content. I know google cares if your content is fresh. Updating old content seems like a cost effective way to increase freshness of content, improve rankings/click through, and isn't as much work as creating new posts.
I have a few questions:
Are you regularly updating old content? If so, what is your process?
Are there any agencies that specialize in updating old content?
Any software we can use to make this easier?
Thanks for your help!
