A keyword search in Keyword Discovery returns a list of keywords sorted in descending order. Further analysis can be performed to help qualify keywords.
Previously, you could perform a keyword analysis only on keywords found by Keyword Discovery. Now, with the advanced Analyze Tool, you can anaylze your own keyword lists too.
The new Advanced Analyze Tool lets you choose from advanced filters, including specific Search Engines and Keyword Databases. And to save you credits, you can choose to show cached data only, fetch all (fetch only missing data) or reanalyze all.
