So, **I was thinking to update the blog post using all the new information.** (The updated information is about 10-20% of the whole blog post.) ----------**How to properly format a post update on a company blog?**----------1) Should I add some disclaimer at the beginning of the post to explain the update?2) Should I add (Updated) or (Revised) to the title?3) Should I somehow highlight the changed sentences or the whole paragraph they are in?---------- **If you have some examples of properly formatted blog post updates - please share**, they would help a lot.

Answer 1

I use red, bold, italicized type at the head of the article, but you can place it at the bottom, provided it's visible in one screen view. Also if you handle the social media for this company it would surely merit a tweet/IG mention etc.
