Do you have any blogs or articles on your website that are 2-3 years old? or maybe more? (no judgement)
When you write for your website, it’s likely that some content is going to become outdated or irrelevant. Search engines favor pages that are up-to-date and relevant, so it’s beneficial to look through your old blog posts every once in a while and rework them or remove them if they’re no longer relevant or useful.
Pro tip: make sure you put a page-level redirect in place if you decide to remove an old page or post!
