Updating SEO of top performing blog posts

Updating the SEO of the top performers in our company's Blog section was a project I was proud to be a part of. My role was to analyze Google Analytics and look for the most visited blog posts. Then, I updated each of them by carefully choosing keywords, adding links, text, and images where needed. I have personally updated over 20 articles in one quarter. The 5 Most Important Rules of Proper Telephone Etiquette (https://www.humanity.com/blog/the-5-most-important-rules-of-proper-telephone-etiquette.html) is still one of the top-performing articles when you search for 'telephone etiquette' on Google.
