Presenting Organic Visibility in an easily digestible but intuitive format--showing changes over time being one of the most useful. I really like the presentation of ONLY commercially viable keyword rankings as well. No use presenting 50k like SEMrush if 90% of them are Page 5+
The content manager and the content briefings make it even fun to write soulless keyword focussed texts. With the rising percentage of content score you get motivated to tweak your text to the max.
