In case you are not familiar with the tool at all, I recommend going through our quick Keyword Planner guide.
The new UI itself is a big step ahead. The material design looks way better that the old version.
Historical search volumes
Now let’s talk about the new features. For me, the major improvement is the historical data retention of search volumes. The new Keyword Planner enables us to see a lot more than search volumes from last 12 months.
We can select our own time frame, pick one of the presets and get historical data even from 2014 (depending on the keyword)!

Mobile search volumes
Another handy feature is the main search volumes chart now includes the mobile search volume share. You had to change the type of charts in the old version to see this.
