How do you guys handle changing the publishing date for the upcoming year. Do you switch it at the beginning of the year? Or update it midway through? Or some other strategy and how does this affect seo if the article is ranking well already? For example, if I have an article that covers 2017 offerings, but then I want to update one or two bits of information in the article for 2018 offerings, rather than rewriting the entire article (because maybe only a few manufacturers updated their offerings).
