This is a list of all analysis you've conducted with Keyword Analyzer.
Every log shows you data on:
Query creation date
Analysis type (quick/full)
Type of device (desktop/mobile)
Once you hover a query from the list, you'll be able to remove it from the history.
Removing a query does not increase your daily limit.
If you want to go back to an analysis you created some time in the past, you can browse your history log by keyword.
