I love the Content Experience features because they give you an objective perspective on how rankable the content is. I also find the Competitors Analysis inside Research Cloud's Organic Search feature super helpful. You can directly check other websites' keywords by the ones only they rank, the ones you have in common, and the ones only you rank. Super practical.
The easy to handle Dashboard and especially the Function of Backlink Check, Keyword Rankings and Google Alerts (SERP Up-Dates). Also the Content-Tool is a Top Feature
