Here is the situation:
Coworker is a content writer working together with the SEO dept. They have to write blogs that are 400+ words long. Lets say the topic is "Digital Accessibility". The SEO guy says that you can't use that word more than 5 times. Get it? Not more than 5 times.. in a blog about... "Digital Accessibility". So I wanted to call bs on that but i lack the knowledge and evidence.
