We use Buzzsumo nearly every day at 99designs as part of our content strategy. Before we start writing any content piece we use the content watcher to research similar articles on the topic and see what gets the most shares. After the article publishes we use the influencer search to find relevant influencers to share the article with. A great tool to build your content creation and distribution strategy!
I am using Buzzsumo more than 1 year now. IT is very helpful for content marketing & research.
I have used this tool for the past couple of years it is great!
