According to adCenter, it now has a new update to the keyword research tool aimed at finding keywords more efficiently and planning campaigns. it is designed to complement the Microsoft adCenter Add-inBeta for Excel by providing access to the deep audience insights directly in the adCenter Research tab.
The new keyword tool looks good and adcenter is providing the option to directly import keywords directly to the corresponding adgroups, this helps the adcenter users to save more time. But still they have to work on some factors, for few keywords there is no impressions or clicks but i'm able to see the CTR for the keywords. Adcenter has to eliminate the errors. Anyway it's great update to the adCenter users.
